Zen 5 with 3D V-Cache
We tested the AMD Ryzen 9 9950X3D for 30 days in a high-end build paired with an RTX 5090. It handled everything we threw at it without breaking a sweat. In Cinebench R23, it scored over 38,000 points multi-core. In gaming at 1080p, it pushed 200+ fps in competitive titles and maintained smooth 1% lows.
What makes this chip special is the 3D V-Cache stacked on top of the Zen 5 cores. The 144 MB total cache is not just a number. In CPU-bound games like Cyberpunk 2077 and Microsoft Flight Simulator, we saw frame rate improvements of 15-25% compared to the non-X3D 9950X. For productivity, the 16 cores and 32 threads ripped through Blender renders and 4K video exports in DaVinci Resolve.

Thermals were manageable with a 360mm AIO cooler. Under full load, the chip peaked at 82C during our Blender stress test. Idle power sat around 45W, which is impressive for a 170W TDP processor. The AM5 platform also means you can drop this into an existing B650 or X670 motherboard with a simple BIOS update.
Our only real complaint is the price. At $679, it is a serious investment. But if you want the best CPU in the world that does not force you to choose between gaming and productivity, this is it. For users focused purely on gaming, the 9800X3D below offers better value.

Zen 5 with Next Gen 3D V-Cache
The AMD Ryzen 7 9800X3D is the #1 best-selling CPU on Amazon for a reason. We tested it for 45 days across 12 games at 1080p, 1440p, and 4K. At 1080p, it averaged 27% higher frame rates than the Intel Core i9-14900K in CPU-bound titles. The 1% lows were equally impressive, staying above 144 fps in every competitive shooter we tested.
The secret is the 96 MB of L3 cache delivered by AMD’s Next Gen 3D V-Cache technology. Games that are sensitive to cache latency, like Factorio, Stellaris, and Cities: Skylines 2, showed dramatic improvements. In Factorio, our UPS benchmark jumped by 34% compared to the 7800X3D. That is a real, noticeable difference for strategy game fans.

Power efficiency surprised us. Despite being a 140W TDP chip, it rarely drew more than 90W during gaming. Temperatures stayed under 70C with a mid-range 240mm AIO. This means you do not need an expensive cooling setup to get the most out of it. The 65W Eco mode also works well if you want whisper-quiet operation.
Forum users on r/buildapc consistently report 144+ fps in modern titles at 1080p with this chip. One user paired it with an RTX 5080 and saw zero bottlenecking at 1440p. Our testing confirmed this. The 9800X3D is the best gaming CPU in the world, full stop.

Who Should Buy the 9800X3D
Gamers who want the highest frame rates possible should buy this CPU. It is especially strong for high-refresh-rate 1080p and 1440p gaming. Esports players will appreciate the consistent 1% lows. Strategy and simulation game fans will see the biggest gains from the massive cache.
Streamers using GPU encoding (NVENC) will also do well here. The 8 cores handle gaming plus background tasks without issue. We streamed at 1080p60 while gaming and saw no frame drops.
Who Should Skip It
Heavy content creators who render video or compile large codebases will find the 8 cores limiting. The 9950X3D or 9950X are better fits for that workload. Also, if you already own a 7800X3D, the upgrade is not worth the cost unless you play cache-sensitive games heavily.
Budget builders should consider the 9600X or 7700X instead. You get 80% of the gaming performance at half the price.

Arrow Lake Architecture
Intel needed a win after the stability issues that plagued 13th and 14th generation CPUs. The Core Ultra 9 285K delivers it. We tested this chip for 30 days in a workstation build and came away impressed by the thermal improvements. Where the i9-13900K would hit 95C under load, the 285K peaked at 78C with the same 360mm AIO.
The Arrow Lake architecture on TSMC’s N3B node is a major step forward. In our SolidWorks CAD workflow, assembly rebuild times dropped by 18% compared to the 13900K. Video editing in DaVinci Resolve was equally smooth, with 8K timeline scrubbing showing no stutter. The 8 P-cores handle heavy threads while the 16 E-cores manage background tasks efficiently.

Gaming performance is solid but not class-leading. At 1080p, it trailed the 9800X3D by about 12% on average. At 4K, the gap shrinks to 3-5% since the GPU becomes the bottleneck. If you are building a 4K gaming rig, this difference is negligible. The integrated graphics are also useful for troubleshooting display issues without a dedicated GPU.
The biggest downside is the platform requirement. You need an LGA 1851 motherboard and CUDIMM memory to hit advertised speeds. This makes upgrades from LGA 1700 expensive. Forum discussions on r/intel suggest LGA 1851 may be a short-lived socket, which raises upgrade path concerns.

Who Should Buy the Core Ultra 9 285K
Professionals who need Intel-specific optimizations for CAD, simulation, or corporate software should consider this chip. The improved thermals and stability make it a reliable workstation choice. Content creators who split time between Adobe Premiere and gaming will also find it well-balanced.
Users coming from older Intel systems who want to stay in the Intel ecosystem will appreciate the familiar overclocking tools and BIOS layouts. For dedicated video editing performance, see our best CPUs for video editing recommendations.
Who Should Skip It
Pure gamers should buy the 9800X3D instead. The frame rate advantage is clear and the platform cost is similar. Users on LGA 1700 should also think carefully. The upgrade requires a new motherboard and RAM, making an AM5 switch equally viable.
Budget builders will find better value in the Core Ultra 7 265KF or AMD’s Ryzen 5 9600X. The 285K’s premium is hard to justify unless you need the full 24-core configuration.

The AMD Ryzen 9 9950X is the non-X3D version of our top pick, and it is a productivity monster. We ran it through Blender, HandBrake, and a full software compile test suite. It completed our Blender BMW render in 78 seconds. The 9950X3D took 82 seconds. For pure productivity, the standard 9950X is actually slightly faster in some workloads.
Where the 9950X3D costs $679, the 9950X sits at $529. That $150 savings buys you a better cooler or faster RAM. For users who do not play cache-sensitive games, this is the smarter buy. In our testing, the 9950X matched or exceeded the 9950X3D in video encoding, compression, and compilation tasks.

Gaming performance is still excellent. At 1440p and 4K, the difference between the 9950X and 9950X3D is 3-5% at most. Only at 1080p with a high-end GPU does the X3D’s cache advantage become noticeable. If you are building a 4K gaming and productivity hybrid, the 9950X is the better value.
Idle power draw impressed us at just 40W. Under full load, it peaks around 200W, so a quality 240mm or 360mm AIO is recommended. Linux users on our team reported flawless performance with no scheduler tweaks needed, unlike Intel’s hybrid architecture which sometimes requires thread affinity adjustments.

Who Should Buy the 9950X
Content creators, programmers, and power users who prioritize multi-threaded performance should buy the 9950X. It is ideal for video editing, 3D rendering, software development, and data analysis. The 16 full-performance cores avoid the scheduling quirks of Intel’s hybrid design.
Users who game at 1440p or 4K will not miss the X3D’s extra cache. The money saved can go toward a better GPU, which matters more at those resolutions. For programming workloads specifically, our best CPUs for programming guide has more details.
Who Should Skip It
Competitive gamers playing at 1080p high refresh should get the 9950X3D or 9800X3D instead. The cache advantage is real in those scenarios. Budget builders will also find the 9900X or 9600X more appropriate for their needs.
Users without adequate cooling should avoid this chip. It runs hot at stock settings and needs a quality AIO or high-end air cooler to maintain boost clocks.

Socket LGA 1700
Raptor Lake, Unlocked
The Intel Core i9-13900K remains one of the fastest CPUs ever made, but it comes with baggage. We tested it with the latest 0x125 microcode and Intel Default Settings BIOS profile. With these fixes applied, stability was rock-solid over our 30-day test period. Without them, we experienced two crashes during Cinebench runs.
Performance is undeniable. The 5.8 GHz boost clock delivers exceptional single-threaded speed. In gaming, it trades blows with the 9950X3D at 1440p and 4K. In productivity, the 32 threads chew through renders and encodes. We exported a 10-minute 4K H.265 video in 4 minutes and 12 seconds. That is workstation-grade speed.

Thermals are the main concern. With a 360mm AIO, we saw peaks of 88C under sustained load. A high-end air cooler will struggle. Intel recommends a 240mm AIO minimum, but we would not go below 360mm for this chip. Power draw spikes to 253W under Turbo, so a quality 850W PSU is essential.
Stock is dwindling. With only 14 units left at major retailers at the time of our research, this chip is approaching end-of-life. If you already own an LGA 1700 system and want a final upgrade, it is a viable option. New builders should look at LGA 1851 or AM5 instead.

Who Should Buy the i9-13900K
Existing LGA 1700 users who want maximum performance without a full platform swap should consider this CPU. It is also a good choice if you find it heavily discounted. At under $500, it is competitive with newer chips. The integrated UHD 770 graphics are handy for systems where the dedicated GPU fails.
Who Should Skip It
New PC builders should avoid LGA 1700. The platform is dead, with no future upgrades. Anyone unwilling to carefully manage BIOS settings and thermals should also look elsewhere. The stability risks, while manageable, are not worth it for most users when the Core Ultra 9 285K exists.

The AMD Ryzen 7 7800X3D was the best gaming CPU in the world before the 9800X3D arrived. It is still an excellent choice, especially at its current price of $377. We tested it side-by-side with the 9800X3D and found a 6-10% gaming performance gap at 1080p. At 1440p and 4K, that gap shrinks to 3-5%.
For gamers on a budget who want X3D performance, the 7800X3D is the sweet spot. The 96 MB L3 cache delivers the same cache-sensitive game benefits as the newer chip. In our testing, Factorio, Cities: Skylines 2, and Starfield all ran smoothly with high frame rates. The chip also handles streaming and multitasking well.
Thermals are a strong point. With a $40 air cooler, we saw gaming temperatures around 68C. The 120W TDP is easier to manage than the 140W of the 9800X3D. Power draw during gaming hovered around 75W, making this an efficient choice for builds where electricity costs matter.
The main downside is the Zen 4 architecture. It is slightly less efficient than Zen 5, and the AM5 platform will eventually phase out support for Zen 4 in favor of newer chips. That said, AMD has committed to AM5 through at least 2027, so you have years of upgrade headroom.
Who Should Buy the 7800X3D
Budget-conscious gamers who want X3D cache benefits should buy this chip. It is also ideal for small form factor builds where thermals matter. The lower TDP means smaller coolers and less case airflow are needed.
Who Should Skip It
Users who want the absolute best gaming performance should spend the extra $70 for the 9800X3D. Productivity-focused builders should consider the 7700X or 9700X instead, which offer similar multi-threaded performance at lower cost.

The AMD Ryzen 9 9900X sits in a unique position. With 12 cores and 24 threads, it splits the difference between the 8-core gaming chips and the 16-core flagship. We tested it in a content creation workstation and found it handles 4K video editing, streaming, and gaming simultaneously without stutter.
In Cinebench R23, the 9900X scored 28,500 multi-core. That is 15% behind the 9950X but 35% ahead of the 9700X. For users who need more than 8 cores but cannot justify the 9950X price, this is the logical middle ground. At $344, it is also one of the better value propositions in the Zen 5 lineup.
Gaming performance is strong but not class-leading. At 1080p, it trails the 9800X3D by about 18%. At 4K, the gap is negligible. If you are building a hybrid gaming and productivity rig, the 9900X makes sense. Pure gamers should look at the 7800X3D or 9800X3D instead.
Temperature management requires attention. Under full load, we saw spikes to 92C with a 240mm AIO. BIOS adjustments to PPT, TDC, and EDC limits brought this down to 84C with minimal performance loss. A 360mm AIO is recommended for sustained workloads.
Who Should Buy the 9900X
Streamers, content creators, and power users who need 12 cores but want to stay under $400 should buy this chip. It is also a good choice for users upgrading from 6-core or 8-core AM4 chips who want a meaningful core count boost without paying flagship prices.
Who Should Skip It
Pure gamers and budget builders have better options. The 9600X at $177 offers better value for gaming, and the 9950X is worth the extra $180 for serious productivity work. Users without quality cooling should also avoid this chip or plan to undervolt.

Raptor Lake, Unlocked
The Intel Core i5-13600K is widely considered one of the best value CPUs ever made. At $319, it delivers near-flagship single-core performance and enough multi-threaded muscle for most users. We tested it in a mid-range gaming build and were impressed by how little it bottlenecks even an RTX 4070 Ti Super.
In gaming at 1440p, the 13600K averaged within 5% of the 13900K. The 6 P-cores handle game threads while the 8 E-cores manage background tasks. We streamed at 1080p60 while playing Call of Duty and saw no frame drops. For a mid-range chip, that is impressive.
The DDR4 compatibility is a hidden advantage. Users upgrading from older Intel systems can reuse their RAM, saving $80-120. We tested with DDR4-3600 and DDR5-5600 and saw only a 3% gaming difference. For budget builders, DDR4 is the smarter choice.
Overclocking is possible but requires patience. We pushed our sample to 5.3 GHz all-core on the P-cores with a 280mm AIO. Temperatures hit 85C under stress test, which is manageable but loud. Stock operation is fine for most users.
Who Should Buy the i5-13600K
Mid-range builders who want Intel compatibility and DDR4 reuse should buy this chip. It is also ideal for media servers and Plex transcoding setups. The 14 cores handle multiple transcode streams without breaking a sweat. Users coming from 10th or 11th gen Intel will see a massive upgrade.
Who Should Skip It
New builders should consider AM5 instead. The LGA 1700 platform has no future, and the 13600K’s stability risks, while lower than the i9, still exist. Users who want the safest upgrade path should look at the Ryzen 5 9600X or Ryzen 7 7700X.

The chip also boots noticeably faster than 13th gen Intel, with our test system posting in 12 seconds versus 18 seconds on a 13700K.

Temperatures are a major improvement over Raptor Lake. Under sustained Cinebench load, the 265KF peaked at 72C with a 240mm AIO. Gaming temperatures sat around 58C. This is a cool-running chip that does not demand exotic cooling.
The main caveat is motherboard compatibility. Some early MSI boards had stability issues with Arrow Lake chips. We recommend sticking to ASUS or Gigabyte Z890 boards for now. BIOS updates have resolved most issues, but it is worth checking compatibility lists before buying.

Who Should Buy the 265KF
Mid-range builders who want Intel’s latest platform and strong multi-tasking should consider this chip. The 20 cores provide headroom for content creation, streaming, and gaming. Users who do not need integrated graphics save money with the KF variant.
Who Should Skip It
Budget builders will find better value in the Ryzen 5 9600X or Ryzen 7 7700X. The LGA 1851 platform requires new motherboards and CUDIMM RAM, which raises total build cost. Users who want guaranteed socket longevity should consider AM5 instead, given forum concerns about LGA 1851’s future.

The AMD Ryzen 5 5500 is proof that you do not need to spend a lot to get solid PC performance. At $84, it is the cheapest CPU in our roundup by a wide margin. Yet it delivers 1080p gaming performance that rivals chips costing three times as much. We tested it with a GTX 1660 Super and saw 100+ fps in Fortnite, Rocket League, and CS2 at medium settings.
The 6 cores and 12 threads handle everyday tasks without issue. We ran Windows 11, Chrome with 15 tabs, Discord, and Spotify simultaneously with no slowdown. The bundled Wraith Stealth cooler is adequate for stock operation, though it runs a bit loud under sustained load. A $20 aftermarket cooler solves this.

The AM4 platform is mature and affordable. B450 and B550 motherboards are widely available for under $80. DDR4 memory is also cheap, with 16GB kits costing around $35. This means a complete CPU, motherboard, and RAM upgrade can be done for under $200. That is unbeatable value.
The limitations are real. PCIe 3.0 means newer GPUs will not run at full bandwidth, though the difference is minimal below RTX 4070 tier. There is no integrated graphics, so a discrete GPU is mandatory. And heavy productivity work will choke the 6 Zen 3 cores. But for budget gaming and general use, this chip is a legend.

Who Should Buy the Ryzen 5 5500
Extreme budget builders, secondary PCs, and entry-level gaming rigs should use this CPU. It is also perfect for upgrading older AM4 systems without replacing the motherboard. We have seen users drop this into 5-year-old B450 boards and get modern performance for under $100.

Who Should Skip It
Anyone building a new high-end system should avoid AM4. The platform is end-of-life, and DDR5/PCIe 5.0 are the future. Users who need integrated graphics should look at the Ryzen 5 5600G instead. Heavy content creators need more cores and a newer architecture.
How to Choose the Best CPU In The World for Your Build
Choosing the right processor comes down to understanding your workload, budget, and platform preferences. After testing 15 CPUs over 3 months, we have identified the key factors that matter most.
Cores and Threads
Modern games use 6-8 cores effectively. For gaming, 6 cores is the minimum we recommend in 2026, and 8 cores is the sweet spot. Productivity workloads scale higher. Video editing, 3D rendering, and software compilation benefit from 12-16 cores. Our testing showed Blender render times improve by 40% going from 8 to 16 cores.
Clock Speed and Cache
Single-core performance still matters for gaming and responsive desktop use. Look for boost clocks above 5.0 GHz for the best gaming experience. Cache size is equally important. AMD’s 3D V-Cache technology proves that extra L3 cache can deliver 15-30% gaming improvements in CPU-bound titles. For strategy games and simulation titles, cache matters more than core count.
Socket and Platform
AMD’s AM5 platform offers the best upgrade path today. AMD has committed to supporting AM5 through at least 2027, meaning a B650 board bought now can accept future Zen 6 and beyond chips. Intel’s LGA 1851 is newer but faces questions about longevity. LGA 1700 is effectively dead. Consider your 3-5 year upgrade plans when choosing a platform.
TDP and Cooling
High-end CPUs need quality cooling. A 170W TDP chip like the 9950X3D requires at least a 240mm AIO. Budget chips like the 9600X and 5500 run fine on basic air coolers. Always factor cooler cost into your total budget. We have seen users buy $600 CPUs and pair them with $20 coolers, then wonder why performance suffers.
Memory Compatibility
AM5 requires DDR5 memory. Intel LGA 1851 also requires DDR5, and specifically CUDIMM kits for optimal speeds. LGA 1700 supports both DDR4 and DDR5. Budget builders can save money with DDR4 on Intel 12th and 13th gen, but new platforms are DDR5-only. Plan for $60-100 in RAM costs for a 16GB DDR5 kit.
Integrated Graphics
Most high-end CPUs do not include integrated graphics. Intel’s K-series and AMD’s X-series chips require a discrete GPU. This is fine for gaming builds but inconvenient if your GPU fails. Consider a cheap backup GPU or choose a chip with integrated graphics if reliability matters. Our best APUs for budget gaming guide covers CPUs with strong integrated graphics.
