Best gaming CPUs: AMD Ryzen X3D and Intel Core Ultra picks

The processor matters most for gaming at 1080p and at high refresh rates, where a fast graphics card can wait on the CPU. In late 2026, AMD’s Ryzen chips with 3D V-Cache (the “X3D” models) lead gaming benchmarks, and Intel’s Core Ultra 200S Plus refresh is the strongest Intel option for mixed gaming and work. This guide groups current CPUs by tier, based on launch list prices, and names the exact models.

We write from manufacturer specifications and published reviews, mainly Tom’s Hardware’s best CPUs for gaming guide (updated October 2026) and CPU benchmark hierarchy, and TechPowerUp’s Ryzen 7 9850X3D review. We have not hands-on tested the products mentioned. Want a full parts list instead? See our gaming PC builds.

How to choose a gaming CPU

• Match the CPU to your graphics card and monitor. At 4K the graphics card does most of the work, so a mid-range CPU loses little. At 1080p and 1440p with a high-refresh monitor, a faster CPU shows up in frame rates. See our graphics card guide to pair the two.
• Gaming cache matters. AMD’s X3D chips stack extra L3 cache on the processor. Tom’s Hardware ranks X3D chips at the top of its gaming hierarchy.
• More cores help with streaming and work, not much with games. Six fast cores are enough for most games today. Intel’s Core Ultra chips add many efficient cores, which helps with encoding, compiling and multitasking.
• Platform cost. AMD’s AM5 socket takes Ryzen 7000 and 9000 chips; Intel’s Core Ultra 200S chips use LGA 1851 and 800-series boards. Both need DDR5 memory.

CPU compatibility checklist

1. Socket and chipset. Ryzen 7000 and 9000 need an AM5 board (A620, B650, B850, X670 or X870). Core Ultra 200S chips need an LGA 1851 board (B860 or Z890).
2. BIOS version. Older AM5 boards may need a BIOS update before a Ryzen 9000 chip will boot. Many boards can update without a CPU installed; check the board’s manual.
3. Cooler. None of the picks here include a cooler. A dual-tower air cooler such as the Thermalright Peerless Assassin 120 SE suits six- and eight-core gaming chips. Check the cooler’s height against your case.
4. Memory. DDR5 only. Choose an AMD EXPO kit for Ryzen and an Intel XMP kit for Core Ultra; our RAM guide explains the difference.
5. Power supply. CPUs draw far less than graphics cards, but a high-end CPU plus a big GPU still needs a quality power supply.

Budget gaming CPUs

AMD Ryzen 5 7600X. Tom’s Hardware’s best budget CPU for gaming: six Zen 4 cores, up to 5.3 GHz, on AM5. Because AM5 also takes Ryzen 9000 chips, you can drop in a faster CPU later without changing the board.

AMD Ryzen 5 9600X. The Zen 5 six-core, up to 5.4 GHz at a 65 W TDP. It sits a little ahead of the 7600X in Tom’s Hardware’s gaming hierarchy (72.6% against 67.3% of the fastest chip). Choose whichever costs less when you buy.

Mid-range gaming CPUs

Intel Core Ultra 5 250K Plus. Tom’s Hardware’s best mid-range gaming CPU. Its 18 cores (6 performance and 12 efficient) make it a strong pick if you stream or work on the same PC. Tom’s found it reaches about 95% of the Core Ultra 7 270K Plus in games. It needs an Intel 800-series motherboard.

AMD Ryzen 7 7800X3D. The previous-generation X3D chip is still one of the fastest gaming CPUs, at 85.6% of the top chip in Tom’s Hardware’s gaming hierarchy. It pairs well with a high-refresh 1440p monitor.

Premium gaming CPUs

AMD Ryzen 7 9800X3D. Tom’s Hardware’s best CPU for gaming overall, and one of the top-selling CPUs on Amazon. It has eight Zen 5 cores, 96 MB of L3 cache and boosts up to 5.2 GHz. Tom’s found the Core Ultra 7 270K Plus about 20% slower in games.

AMD Ryzen 7 9850X3D. A faster-clocked version of the 9800X3D, up to 5.6 GHz. It tops Tom’s Hardware’s gaming hierarchy, but TechPowerUp measured only about 2.5% more performance at 1080p and 0.5% at 4K. Buy it only if the cost difference is small.

Intel Core Ultra 7 270K Plus. Tom’s Hardware’s Intel alternative at the top: 24 cores (8 performance and 16 efficient), up to 5.5 GHz. It trails the X3D chips in games but is much stronger in multi-threaded work. Tom’s found it about 10% faster than the Core Ultra 7 265K.

What about the Ryzen 9 9950X3D2? Tom’s Hardware names it the top pick for buyers who also run heavy workloads, but reviews found its gaming performance tied with the 9950X3D. For a gaming PC, the 9800X3D is the better buy, so we don’t list it.

FAQ

AMD or Intel for gaming? For pure gaming, AMD’s X3D chips lead Tom’s Hardware’s benchmarks. Intel’s Core Ultra Plus chips are the better pick if you also do a lot of multi-threaded work.

Do I need an X3D chip? Not for 4K or for 60 FPS gaming. X3D chips pay off most with a fast graphics card and a high-refresh monitor.

What about an older DDR4 PC? Tom’s Hardware still recommends the Ryzen 7 5800X3D as a drop-in upgrade for AM4 boards. Our RAM guide has a DDR4 kit for older builds.

Verdict

For a budget build, the Ryzen 5 7600X or 9600X is the start of a long-lived AM5 platform. The Ryzen 7 7800X3D is the value gaming pick, and the Core Ultra 5 250K Plus suits gamers who also stream. For the fastest gaming PC, buy the Ryzen 7 9800X3D. See how these fit into complete parts lists in our gaming PC builds.
