Our Picks

Best for Gaming1 of 7

AMD Ryzen 7 9800X3D

The Ryzen 7 9800X3D pairs 96MB of L3 cache with eight Zen 5 cores.

Best for

Gaming-first builds.

Choose another pick if you can't accept this: no cooler in the box.
AMD Ryzen 7 9800X3D

Why we like it

AMD moved the cache below the cores on this generation, which lets it clock higher than the 7800X3D. Its 96MB L3 cache ranks second of 7 here, behind the Ryzen 9 9950X3D (128MB) and ahead of the Core Ultra 7 265K (30MB). Its 5.2GHz boost clock ranks sixth of 7 here, behind the Ryzen 9 9950X3D (5.7GHz) and ahead of the Ryzen 5 7600 (5.1GHz).

On core count it ties with the Ryzen 7 9700X at 8 cores. On rated power it sits mid-pack at 120W: the Ryzen 7 9700X offers 65W, and the Ryzen 9 9950X comes in at 170W. It also comes with an unlocked multiplier, a first for AMD's X3D chips. It was priced above the Ryzen 7 9700X and below the Core Ultra 9 285K at the time of writing.

Pros

  • 96MB of L3 cache from 3D V-Cache
  • Integrated graphics for display output without a graphics card
  • Second-generation 3D V-Cache placed under the cores
  • Unlocked multiplier, a first for AMD's X3D chips

Cons

  • No cooler in the box
  • Costs more than the Ryzen 5 7600 at the time of writing

The catch

What it gives up: no cooler in box, unlike the Ryzen 5 7600; by contrast, the Ryzen 5 7600 has it.

Largest Game Cache2 of 7

AMD Ryzen 9 9950X3D

The Ryzen 9 9950X3D combines sixteen cores with 128MB of L3 cache.

Best for

Games that are limited by the CPU at high frame rates.

Skip if

Skip it if this is a deal-breaker for you: 170W rating calls for a large air cooler or a 280mm-plus AIO.
AMD Ryzen 9 9950X3D

Why we like it

It is the chip for players who also render, compile or encode on the same machine. Nothing else here matches its 128MB L3 cache; the Ryzen 7 9800X3D comes closest at 96MB. On boost clock it ties with the Ryzen 9 9950X and the Core Ultra 9 285K at 5.7GHz.

It matches the Ryzen 9 9950X on core count (16 cores). It matches the Ryzen 9 9950X on rated power (170W). It also comes with 3D V-Cache on one of its two core dies and a design aimed at both games and content creation.

It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; a 600-series board may need a BIOS update first, so check the maker's CPU support list for the minimum version. It was the most expensive pick when we checked, so weigh what it adds over the Ryzen 9 9950X.

Best Mid-Range3 of 7

AMD Ryzen 7 9700X

The Ryzen 7 9700X runs eight Zen 5 cores at a 65W default rating.

Best for

Balanced builds.

Skip if

Look at the others if this bothers you: no cooler in the box.
AMD Ryzen 7 9700X

Why we like it

It needs only a modest cooler and has room to grow with AMD's power boost setting. On L3 cache it ties with the Ryzen 5 7600 at 32MB. On boost clock it ties with the Core Ultra 7 265K at 5.5GHz.

It matches the Ryzen 7 9800X3D on core count (8 cores). It matches the Ryzen 5 7600 on rated power (65W). You also get the Zen 5 architecture.

It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; a 600-series board may need a BIOS update first, so check the maker's CPU support list for the minimum version. No cooler is included; a single-tower air cooler is enough at its rating. On price it sat third of 7, between the cheaper Core Ultra 7 265K and the pricier Ryzen 7 9800X3D, at the time of writing.

Best Budget4 of 7

AMD Ryzen 5 7600

The Ryzen 5 7600 is the six-core AM5 chip with a Wraith Stealth cooler included.

Best for

Cost-conscious builds.

Skip if

Skip it if this is a deal-breaker for you: 6 cores leave less headroom for streaming alongside games.
AMD Ryzen 5 7600

Why we like it

The cooler saves money on a first AM5 build. It matches the Ryzen 7 9700X on L3 cache (32MB). Its 5.1GHz boost clock is the lowest in this group; the Ryzen 9 9950X3D leads at 5.7GHz.

On core count it trails the group at 6 cores, while the Core Ultra 9 285K offers 24 cores. On rated power it ties with the Ryzen 7 9700X at 65W. It also comes with the Zen 4 architecture, a 5nm process and PCIe 5.0 support on AM5.

It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; check the board's CPU support list for the minimum BIOS version. It cost the least of the 7 picks at the time of writing, with the Core Ultra 7 265K the next step up.

Best for Multi-Threaded Work5 of 7

AMD Ryzen 9 9950X

The Ryzen 9 9950X is AMD's sixteen-core AM5 chip without V-Cache.

Best for

Rendering and compiling.

Skip if

Worth skipping when 170W rating calls for a large air cooler or a 280mm-plus AIO is a problem.
AMD Ryzen 9 9950X

Why we like it

It aims at rendering, compiling and encoding more than frame rates. On L3 cache it sits mid-pack at 64MB: the Ryzen 9 9950X3D offers 128MB, and the Core Ultra 7 265K comes in at 30MB. On boost clock it ties with the Ryzen 9 9950X3D and the Core Ultra 9 285K at 5.7GHz.

It matches the Ryzen 9 9950X3D on core count (16 cores). It also offers AMD's recommendation of a liquid cooler. It needs an AM5 board (A620, B650, B850, X670 or X870 series) and DDR5 memory; a 600-series board may need a BIOS update first, so check the maker's CPU support list for the minimum version.

Budget for a dual-tower air cooler or a 240mm-plus AIO, since none is included. Its price falls between the Core Ultra 9 285K and the Ryzen 9 9950X3D, based on our last check.

Intel Core Ultra 7 265K

Why we like it

It is strong in multi-threaded work and supports only DDR5. Its 30MB L3 cache is the smallest in this group; the Ryzen 9 9950X3D leads at 128MB. It matches the Ryzen 7 9700X on boost clock (5.5GHz).

On core count it sits mid-pack at 20 cores: the Core Ultra 9 285K offers 24 cores, and the Ryzen 5 7600 comes in at 6 cores. On rated power it ties with the Core Ultra 9 285K at 125W. Like the Core Ultra 9 285K, it has an LGA1851 socket, while the Ryzen 9 9950X3D uses an AM5 socket.

It also comes with 8 performance and 12 efficient cores and a built-in NPU for AI features. It needs an LGA1851 board (Intel 800-series chipset) and DDR5 memory; LGA1700 boards and coolers without an LGA1851 mounting kit will not fit. It was priced above the Ryzen 5 7600 and below the Ryzen 7 9700X at the time of writing.
