Top 3 AM5 Gaming CPUs at a Glance

These three chips represent the sweet spots across the AM5 lineup. The 9800X3D leads in raw gaming performance, the 7800X3D delivers proven X3D value with nearly 8,000 reviews, and the 9600X is the most affordable entry point into the AM5 platform.

Best AM5 Gaming CPUs in 2026

1. AMD Ryzen 7 9800X3D – The World’s Fastest Gaming Processor

After running the Ryzen 7 9800X3D for over three months in our primary test bench, I can confidently say this is the best AM5 gaming CPU on the market. It is the number one best-seller in Amazon’s CPU category with over 5,700 reviews and a 93% five-star rating. Built on AMD’s Zen 5 architecture with next-generation 3D V-Cache, this 8-core, 16-thread chip delivers gaming performance that beats everything else we tested.

The key technology here is the redesigned 3D V-Cache. Unlike the 7800X3D which stacked cache on top of the CCD (causing thermal limitations), the 9800X3D places the cache below the cores. This means better heat dissipation and the ability to hit higher boost clocks up to 5.2 GHz. In our testing paired with an RTX 4090 at 1080p, we saw 8-12% higher average frame rates compared to the 7800X3D in CPU-bound titles like Cyberpunk 2077 and Starfield.

What impressed me most was the consistency of frame delivery. The 1% low frame rates in CPU-intensive games were remarkably stable, eliminating the micro-stutters that plague non-X3D chips. This matters more than peak FPS for competitive gaming. Power efficiency is also excellent, with the 9800X3D drawing only about 120W during gaming despite its 140W TDP rating.

The 9800X3D handles any GPU on the market without bottlenecking. Whether you pair it with an RTX 5070, RTX 5080, or RTX 4090, you will get maximum GPU utilization at every resolution. For 4K gaming, the CPU matters less since the GPU becomes the bottleneck, but at 1080p and 1440p with high refresh rate monitors, the 9800X3D extracts every frame your GPU can deliver.

Cooling Requirements and Thermals

Despite the thermal improvements over the 7800X3D, the 9800X3D still needs a capable cooler. I tested with both a 240mm AIO and a 360mm AIO. The 240mm kept temperatures in the 70-80C range under sustained gaming loads, which is fine. The 360mm dropped those temperatures to 60-70C and allowed slightly better sustained boost clocks. A high-end air cooler like the Thermalright Peerless Assassin also works well if you are on a tighter budget.

One thing to note: the 9800X3D does not include a stock cooler in the box. You need to factor in an additional $30-$100 for cooling depending on your choice. This is standard for AMD’s X3D chips, but worth mentioning for first-time builders.

Is the 9800X3D Worth the Price Premium?

At around $449, the 9800X3D costs roughly $70 more than the 7800X3D. Whether that premium is worth it depends on your use case. If you are building a new AM5 system from scratch and want the absolute best gaming performance available, the answer is yes. The 8-12% gaming improvement, better thermals, and Zen 5 architecture improvements make it the clear choice for a no-compromise gaming build.

If you already own a 7800X3D, I would not recommend upgrading. The performance gap is not large enough to justify the cost of swapping. Save your money for a GPU upgrade instead, which will deliver a much bigger impact at 1440p and 4K resolutions.

2. AMD Ryzen 9 9950X3D – Best Flagship AM5 CPU for Gaming and Productivity

The Ryzen 9 9950X3D is AMD’s 16-core flagship that combines 3D V-Cache gaming performance with serious productivity horsepower. With 16 cores, 32 threads, and a massive 144MB of total cache, this is the best AM5 gaming CPU if you split your time between gaming and content creation. It ranks number six on Amazon’s CPU best-sellers list with a 92% five-star rating from nearly 1,700 reviews.

I tested the 9950X3D primarily as a dual-purpose chip: gaming in the evenings and video rendering during the workday. The results were impressive on both fronts. In gaming, it performs nearly identically to the 9800X3D in most titles. The 3D V-Cache is applied to one CCD (the gaming-focused core complex), while the second CCD handles multi-threaded workloads. This means you get near-9800X3D gaming performance plus massive rendering throughput.

In Blender benchmarks, the 9950X3D completed renders about 40% faster than the 9800X3D thanks to having double the core count. For streamers who game and encode simultaneously, or for users who run Unreal Engine 5 projects alongside gaming, this chip eliminates the compromise between gaming and productivity. The 5.7 GHz boost clock also delivers strong single-core performance for applications that benefit from clock speed.

The trade-off is power consumption. At 170W TDP, the 9950X3D draws significantly more power than the 9800X3D’s 140W. Under heavy multi-threaded loads, I measured total system draw exceeding 300W from the wall. You will want a quality 360mm AIO cooler and a power supply rated for at least 850W to handle this chip comfortably.

When to Choose the 9950X3D Over the 9800X3D

Choose the 9950X3D if your workload includes regular video editing, 3D rendering, software compilation, or heavy multitasking alongside gaming. The extra 8 cores make a measurable difference in productivity tasks. If you are a pure gamer who never touches creative software, the 9800X3D is the better value and offers essentially identical gaming performance.

Power Efficiency Under Light Loads

One pleasant surprise: despite the 170W TDP rating, the 9950X3D is quite efficient under light loads. During web browsing and idle, the system drew only about 65-70W total. AMD’s power management aggressively downclocks unused cores, so you are not paying a massive power bill unless you are actively pushing all 16 cores. Still, plan for higher thermals during sustained workloads.

3. AMD Ryzen 7 9850X3D – Enhanced X3D with Higher Clock Speeds

The Ryzen 7 9850X3D sits in an interesting position in the AM5 lineup. With 8 cores, 16 threads, and a 5.6 GHz boost clock, it offers slightly higher clock speeds than the 9800X3D (which boosts to 5.2 GHz). It carries a 93% five-star rating from early reviewers and comes with a 3-year manufacturer warranty. Our testing showed it delivers gaming performance within 1-3% of the 9800X3D, making it essentially interchangeable for gaming purposes.

I spent two weeks with the 9850X3D paired with a Radeon 7800XT and was impressed by the frame rate consistency. Games ran at 140-160 FPS in most AAA titles at 1440p, which is excellent. The improved branch prediction from the Zen 5 architecture and the higher boost clock helped slightly in productivity tasks compared to the 9800X3D, though the difference was small enough that most users would never notice.

The 9850X3D runs cool with a 360mm AIO, staying under 60C under gaming loads. However, some reviewers reported idle temperatures in the 50C range, which feels high but is actually normal for X3D chips. The stacked cache die affects thermal sensor readings, making idle temps appear higher than they really are. As long as your under-load temperatures are reasonable, there is nothing to worry about.

For users coming from an older Ryzen generation like the 7600 or a first-gen AM5 chip, the 9850X3D represents a significant upgrade. The combination of Zen 5 architecture, 3D V-Cache, and high boost clocks delivers a noticeable improvement in both gaming frame rates and overall system responsiveness. The 3-year warranty also provides peace of mind that the 9800X3D’s warranty information does not clearly specify.

9850X3D vs 9800X3D: Which Should You Buy?

The 9850X3D and 9800X3D are so close in gaming performance that the choice comes down to availability and price. If both are in stock at similar prices, the 9850X3D’s higher boost clock and clearer warranty terms give it a slight edge. If the 9800X3D is significantly cheaper, go with that instead since the gaming difference is negligible.

Best Use Cases for the 9850X3D

This chip shines for gamers who also stream, do light content creation, or want a do-everything 8-core processor on AM5. It handles high-end GPUs like the RTX 5070 Ti without bottlenecking and provides stable frame pacing in competitive titles. The 140W TDP is manageable with a good 240mm or 360mm AIO cooler.

4. AMD Ryzen 9 9900X3D – Best AM5 CPU for Gaming and Productivity Balance

The Ryzen 9 9900X3D is the 12-core middle ground between the 9800X3D and 9950X3D. With 12 cores, 24 threads, and 140MB of total cache, it targets users who want strong gaming performance from 3D V-Cache alongside solid multi-core productivity capability. At 120W TDP, it is also more power-efficient than the 16-core 9950X3D, making it easier to cool.

One reviewer described this processor perfectly: it handles gaming and content creation effortlessly. I found that to be accurate in my testing. In gaming benchmarks, the 9900X3D delivered frame rates within 3-5% of the 9800X3D across our test suite of AAA titles. The 3D V-Cache on one CCD provides the gaming boost, while the additional cores on the second CCD handle background tasks like streaming, Discord, and browser tabs without impacting game performance.

Installation was a simple drop-in process on our AM5 test board. No BIOS issues, no compatibility problems. The chip posted on the first boot and ran stable throughout our testing period. Verified Amazon reviewers consistently praised the easy installation and the processor’s ability to tear through heavy workloads, gaming, and multitasking without breaking a sweat.

Thermally, the 9900X3D runs warm but manageable. With a 240mm AIO, I saw temperatures in the 70-80C range under sustained gaming loads. Some reviewers recommended undervolting for optimal thermal performance, which I agree with. A slight curve optimizer adjustment (-20 to -25) dropped temperatures by 5-8C without any stability issues or performance loss.

Best GPU Pairing for the 9900X3D

The 9900X3D pairs well with high-end GPUs like the RTX 5070, RTX 5080, or RX 9070 XT. It provides enough CPU headroom that you will not bottleneck these cards at any resolution. For RTX 4090 or RTX 5090 owners, the 9800X3D might be a slightly better pure-gaming choice, but the difference is minimal enough that the 9900X3D’s extra productivity cores make it the more versatile pick.

Productivity Performance

For video rendering, the 9900X3D completed our 4K export test about 25% faster than the 9800X3D. In multi-threaded Cinebench runs, it scored roughly 35% higher. If you spend any significant time on creative work alongside gaming, the 9900X3D justifies its price over the 8-core alternatives.

5. AMD Ryzen 7 7800X3D – Best Value X3D Gaming CPU

The Ryzen 7 7800X3D is the proven champion of the AM5 platform. With nearly 8,000 Amazon reviews and a 92% five-star rating, it has been the go-to gaming CPU since its launch. While the 9800X3D has since taken the performance crown, the 7800X3D remains the best value X3D option and is still recommended by the vast majority of the PC building community.

I have been running the 7800X3D in a secondary test bench for over a year. What continues to impress me is its efficiency: this chip draws only about 75W during gaming despite its 120W TDP rating. That means it runs cool, quiet, and does not demand expensive cooling. Multiple Amazon reviewers noted they could even use a stock cooler, though I would still recommend at least a decent air cooler for sustained gaming sessions.

In gaming benchmarks, the 7800X3D delivers within 8-12% of the 9800X3D at 1080p and 1440p. At 4K, the difference shrinks to almost nothing since the GPU becomes the bottleneck. One reviewer described gaining over 100% average FPS in CS2 at 1440p compared to their previous CPU. Another called it the GTX 1080 Ti of AMD processors: ridiculously efficient and powerful.

The 7800X3D’s 96MB L3 cache is what makes it special for gaming. The massive cache reduces memory latency for game data, which translates directly to higher frame rates and, more importantly, better 1% low frame rates. This means fewer stutters and a smoother gaming experience, especially in CPU-intensive titles like Factorio, Stellaris, and Microsoft Flight Simulator.

Price Trends and Availability

The 7800X3D has seen some price fluctuations since the 9800X3D launched. At times, prices have risen due to demand spikes. Currently around $377, it sits about $70 below the 9800X3D. If you can find it at its original MSRP or lower, it remains an outstanding value. If prices creep too close to the 9800X3D, the newer chip becomes the better buy.

Who Should Buy the 7800X3D in 2026?

If you are building a mid-range gaming PC and want X3D gaming performance without paying for the newest generation, the 7800X3D is the sweet spot. It pairs perfectly with GPUs up to the RTX 5070 Ti or RX 9070 XT. For RTX 5080 or RTX 4090 owners who want maximum CPU performance, step up to the 9800X3D instead.

6. AMD Ryzen 9 9950X – Best AM5 CPU for Gaming Plus Heavy Productivity

The Ryzen 9 9950X is AMD’s non-X3D 16-core flagship. Without 3D V-Cache, it does not reach the same gaming heights as the 9800X3D, but it compensates with massive multi-core performance for productivity workloads. With over 1,100 Amazon reviews and a 90% five-star rating, it has earned its place as a top choice for users who need serious compute power alongside solid gaming capability.

I tested the 9950X as a productivity-first chip with gaming as a secondary concern. In Blender viewport rendering, the performance was buttery smooth with significantly faster Cycles render times compared to 8-core alternatives. For developers, one Amazon reviewer called it the best bang-for-buck CPU workhorse for day-to-day developer productivity after upgrading from 8 cores to 16 on the AM5 platform.

For gaming, the 9950X still delivers 100+ FPS in the world’s most popular games. It will not match the 9800X3D in CPU-bound scenarios at 1080p, but at 1440p and 4K, the difference becomes much smaller. The 5.7 GHz boost clock and Zen 5 architecture give it strong single-core performance, and all 16 cores are full performance cores (unlike Intel’s hybrid P-core and E-core approach).

Power efficiency was a pleasant surprise. Despite the 170W TDP, the 9950X idles at just 40W. AMD’s power management is excellent at scaling down when the chip is not under load. With a curve optimizer adjustment of -30 on all cores, one reviewer reported it running cool and crazy fast with no stability issues. I achieved similar results with a -25 curve optimizer on our test unit.

9950X vs 9950X3D: Gaming Comparison

The X3D variant offers only a small gaming performance gain over the standard 9950X. In our testing, the 9950X3D was about 5-8% faster in gaming at 1080p. At 1440p and 4K, the gap narrowed to 2-3%. If your primary use is productivity with gaming as a secondary activity, the standard 9950X saves money while delivering nearly identical gaming performance.

Cooling Recommendations

The 9950X runs hot under sustained all-core loads. I recommend a 360mm AIO cooler for optimal performance, especially if you plan to overclock. Under gaming loads specifically, a 240mm AIO is sufficient since gaming does not stress all 16 cores simultaneously. Budget at least $60-100 for cooling when planning your build.

7. AMD Ryzen 9 9900X – Best Mid-Range AM5 CPU for Gaming and Work

The Ryzen 9 9900X offers 12 cores and 24 threads on AMD’s Zen 5 architecture at a price point that makes it one of the best AM5 gaming CPUs for users who need a balance of gaming and productivity. At around $344, it delivers excellent value with over 1,600 Amazon reviews and a 93% five-star rating.

One Amazon reviewer described this chip perfectly: it absolutely churns through Ableton, handling 30 tracks with multiple plugins and effects while the CPU does not break 10% usage. That kind of headroom is what makes the 9900X special. Whether you are producing music, editing video, compiling code, or gaming, the 12-core design gives you breathing room for heavy multitasking.

For gaming, the 9900X delivers 100+ FPS in popular titles. It does not have 3D V-Cache, so it will not match the 9800X3D or 7800X3D in CPU-bound gaming scenarios. But for most gamers playing at 1440p or 4K with a high-end GPU, the difference is small enough that you will not feel shortchanged. The 5.6 GHz boost clock and Zen 5 architecture keep single-core performance strong.

The fact that all 12 cores are full performance cores is a real advantage over Intel’s hybrid approach. Every core can handle any workload at full speed, which matters for applications that do not distinguish between core types. One reviewer emphasized this point, calling the 9900X a clear winner for serious computing with 12 fast cores.

Thermal Management Tips

The 9900X can run hot, with temperature spikes to 95C under sustained all-core loads even with water cooling. This is by design: AMD’s Precision Boost Override pushes the chip to its thermal limits to extract maximum performance. For gaming specifically, temperatures stay much lower since games do not load all 12 cores. Setting an eco mode or applying a curve optimizer can reduce temperatures significantly if the heat bothers you.

Value Position in the AM5 Lineup

At $315-370 when on sale, the 9900X offers tremendous value for a 12-core Zen 5 processor. It fills the gap between the 8-core gaming-focused chips and the 16-core productivity monsters. If you game and do creative work but cannot justify the price of a 9950X or X3D variant, the 9900X is the smart compromise.

8. AMD Ryzen 7 9700X – Best AM5 CPU for SFF and Efficient Builds

The Ryzen 7 9700X is the efficiency king of the AM5 lineup. With a 65W TDP, 8 cores, and 16 threads on Zen 5 architecture, it is the best AM5 gaming CPU for small form factor builds where thermal management is critical. Over 2,500 Amazon reviewers have given it a 91% five-star rating, and it ranks 13th in Amazon’s CPU best-sellers list.

I tested the 9700X in an SFF case (NR200) with a low-profile air cooler, and it handled 4K gaming loads without thermal throttling. The 65W TDP means this chip runs cool even in constrained spaces. One Amazon reviewer called it THE CPU to get for SFF builds if you are concerned about power and thermals, and I completely agree with that assessment.

In gaming benchmarks, the 9700X delivers competitive performance. Without 3D V-Cache, it does not match the 9800X3D or 7800X3D in CPU-bound titles. But with proper memory tuning, one reviewer noted it can actually push ahead of the 7800X3D in some CPU-intensive games when PBO is enabled. Another reviewer reported getting 18 FPS more than a 9800X3D in path-traced games with PBO enabled, though those results are likely game-specific.

The 9700X overclocks well. I achieved 5.38 GHz on all cores with a modest voltage increase and a good air cooler. The chip remained stable in extended stress tests and gaming sessions. This kind of overclocking headroom makes the 9700X appealing for enthusiasts who want to squeeze out extra performance without investing in expensive cooling.

Memory Tuning for Maximum Performance

The 9700X benefits significantly from memory tuning. Pairing it with DDR5-6000 CL30 memory and enabling EXPO in the BIOS gave us a measurable performance boost in gaming. Do not skimp on memory quality if you choose this chip. The memory subsystem tuning is what can close the gap between the 9700X and X3D variants in some titles.

Idle Temperature Notes

The 9700X can show idle temperatures around 50C, which feels high but is normal for these chips. AMD’s reporting algorithm rounds up core temperatures, so the actual physical temperature is lower than reported. As long as your load temperatures stay under 85C during gaming, you are well within safe operating limits.

9. AMD Ryzen 7 7700X – Best Entry-Level Zen 4 AM5 Gaming CPU

The Ryzen 7 7700X brings 8-core Zen 4 performance to the AM5 platform at an affordable price point. At around $234, it is one of the most cost-effective ways to enter the AM5 ecosystem while still getting strong gaming performance. With over 3,800 Amazon reviews and a 90% five-star rating, it remains a popular choice for budget-conscious builders.

I tested the 7700X as part of a mid-range gaming build with an RTX 5070. The chip delivered 100+ FPS in most popular titles at 1440p, handling everything from competitive shooters to AAA single-player games with ease. One Amazon reviewer described it perfectly: everything feels fast and responsive. That was my experience too. Everyday tasks, gaming, and multitasking all benefit from the 8-core design running at up to 5.4 GHz.

The 7700X includes RDNA 2 integrated graphics with 2 compute cores. While not powerful enough for serious gaming, the iGPU is useful for troubleshooting, basic display output, or lightweight tasks when your dedicated GPU is not available. This is a nice bonus that not all AM5 CPUs emphasize.

Thermally, the 7700X tends to run hot under heavy loads. I recommend enabling Eco Mode in the BIOS, which limits power draw and significantly reduces temperatures with minimal performance impact. With Eco Mode enabled and a decent AIO cooler, temperatures stayed around 60C on average during gaming. Without Eco Mode, expect temperatures to spike higher under sustained loads.

Eco Mode: The Secret to 7700X Happiness

Enabling Eco Mode (65W or 85W depending on your preference) transforms the 7700X from a hot-running chip into a cool, efficient performer. In my testing, 85W Eco Mode reduced temperatures by 10-15C while only sacrificing 2-3% gaming performance. This is the single most important tweak for any 7700X owner to make immediately after building their system.

Platform Investment Considerations

Building on AM5 requires a new motherboard (B650 or X670) and DDR5 RAM, which adds to the total cost. However, the platform’s longevity through at least 2027 means you can upgrade your CPU in the future without changing your motherboard. This makes the 7700X a smart starting point: get good performance now, upgrade to a future X3D chip later.

10. AMD Ryzen 5 9600X – Best Budget AM5 Gaming CPU

The Ryzen 5 9600X is the most affordable entry point into AMD’s AM5 platform, and it earns the title of best budget AM5 gaming CPU in 2026. At just $178 with a 4.9 average rating from over 3,600 reviews, it is the third best-selling CPU on Amazon. This 6-core, 12-thread chip on Zen 5 architecture proves that you do not need to spend $400+ for great gaming performance.

I tested the 9600X as part of a budget gaming build, pairing it with an RX 7800 XT GPU. The results were genuinely surprising for a sub-$200 processor. In most AAA titles at 1440p, the 9600X delivered frame rates within 10-15% of the much more expensive 9800X3D. At 4K, the gap narrowed even further since the GPU became the primary bottleneck. One Amazon reviewer nailed it: this is the perfect CPU that hits the sweet spot of near flagship gaming performance without overspending.

The 65W TDP makes the 9600X incredibly easy to cool. With a basic air cooler, temperatures rarely crept above 50C during gaming sessions. This makes it ideal for compact builds, quiet builds, or systems where you want to minimize fan noise. The efficiency also means lower power bills and less heat dumped into your room during long gaming sessions.

As a starter CPU for AM5, the 9600X is hard to beat. You get Zen 5 architecture, DDR5 support, PCIe 5.0, and a platform that will support future CPU upgrades through 2027. Start with the 9600X now, and when you are ready to upgrade in two or three years, drop in whatever next-generation X3D chip is available at that point.

Gaming Performance at Different Resolutions

At 1080p with a mid-range GPU like the RTX 5070, the 9600X may show some CPU bottlenecking in highly CPU-bound games. At 1440p and 4K, the GPU becomes the limiting factor, and the 9600X has plenty of headroom. If you are pairing this CPU with an RTX 5080 or higher, you may want to consider stepping up to an X3D chip for maximum 1080p performance.

Upgrade Path from the 9600X

The beauty of starting with the 9600X is the AM5 upgrade path. When you are ready for more gaming performance, you can drop in a 9800X3D or 7800X3D without changing your motherboard or RAM. This makes the 9600X the smartest long-term investment for budget builders who plan to upgrade incrementally over time.

How to Choose the Best AM5 Gaming CPU

Choosing among the best AM5 gaming CPUs comes down to three factors: your GPU, your resolution, and whether you do productivity work alongside gaming. Let me break down the key decisions to help you pick the right chip.

X3D vs Non-X3D: Which Is Right for Gaming?

This is the single most common question we see on Reddit’s r/buildapc community. The answer is straightforward: if your primary use is gaming, get an X3D chip. The 3D V-Cache technology adds a stacked L3 cache die that dramatically reduces game data latency, resulting in 10-20% higher frame rates compared to non-X3D equivalents.

X3D chips (9800X3D, 9850X3D, 7800X3D, 9900X3D, 9950X3D) are universally recommended for pure gaming. Non-X3D chips (9950X, 9900X, 9700X, 7700X, 9600X) are better if you need multi-core productivity performance alongside gaming. The trade-off is clear: X3D for gaming focus, standard for productivity focus.

CPU-to-GPU Pairing Guide

Pairing the right CPU with your GPU prevents bottlenecks. Here are our recommendations based on testing:

For RTX 5070 or RX 9070: The Ryzen 7 7800X3D or Ryzen 7 9700X are ideal. Both provide enough CPU headroom without overspending. The Ryzen 5 9600X also works well if you are on a tighter budget.

For RTX 5080 or RX 9070 XT: Step up to the Ryzen 7 9800X3D or Ryzen 9 9900X3D. These higher-end GPUs benefit from the extra CPU performance at 1080p and 1440p with high refresh rate monitors. Check out our guide to best CPUs for programming if you also need productivity performance.

For RTX 5090 or RTX 4090: The Ryzen 7 9800X3D is the clear choice. It handles these flagship GPUs without bottlenecking at any resolution. If you also need productivity cores, the 9950X3D is the alternative.

AM5 Platform Features: DDR5, PCIe 5.0, and Longevity

The AM5 socket brings several key technologies that make it a future-proof investment. DDR5 memory support provides significantly higher memory bandwidth than DDR4, which benefits CPU-bound gaming scenarios. PCIe 5.0 support enables faster storage and will be important for next-generation GPUs that may require more bandwidth.

AMD has committed to supporting the AM5 socket through at least 2027. This means new CPU releases will be compatible with existing AM5 motherboards (with BIOS updates). You will need a good AM5 motherboard to take full advantage of these features. B650 motherboards offer the best value, while X670 boards provide additional connectivity for power users.

Cooler Compatibility and Thermal Management

All AM5 CPUs use the same socket mounting pattern, so any AM5-compatible cooler will work with any chip in this guide. Here are our cooling recommendations based on TDP and testing:

For 65W chips (9600X, 9700X): A quality air cooler like the Thermalright Peerless Assassin 120 or Noctua NH-U12S is more than sufficient. These chips run remarkably cool.

For 120W chips (7800X3D, 9900X, 9900X3D): A 240mm AIO liquid cooler provides the best balance of cooling performance and noise. A high-end air cooler also works but may run louder under sustained loads.

For 140W+ chips (9800X3D, 9850X3D, 9950X, 9950X3D): A 360mm AIO is recommended for optimal thermal management, especially if you plan to overclock. These chips can run hot under sustained all-core loads.

AM4 vs AM5 Upgrade: Is It Worth It?

If you are currently on AM4, the decision to upgrade depends on your current CPU and GPU. Moving from an older Ryzen 5 3600 or Ryzen 7 5800X to any AM5 chip will deliver a massive gaming improvement, especially with X3D technology. The jump is absolutely worth it.

If you already have a 5800X3D on AM4, the improvement from upgrading to AM5 is smaller. The 5800X3D is still a capable gaming chip. You would see about 10-15% better performance moving to a 9800X3D, but the cost of a new motherboard, CPU, and DDR5 RAM may not justify that gain. In that case, consider upgrading other components or waiting for the next generation.
