The short answer

The Ryzen 7 9800X3D is the better buy here: it's both faster for gaming and gives more performance per dollar.

  • Ryzen 7 9800X3D is about 47% faster for gaming at 1080p (gaming index 97.0 vs 65.8).
  • Ryzen 7 9800X3D is roughly 11% faster in multi-core work, an edge in rendering, encoding and compiling.
  • Core i7-12700K is the cheaper chip right now, by roughly 33%.
  • Ryzen 7 9800X3D delivers about 11% more gaming performance per dollar.
  • Core i7-12700K has more cores (12C/20T vs 8C/16T), which helps in heavily threaded workloads.

Gaming performance

CPU-bound gaming score: a geometric mean of in-game frame rates at 1080p, normalized so the fastest gaming CPU we track = 100.

Ryzen 7 9800X3D97.0
Core i7-12700K65.8

Does the CPU matter at 1440p or 4K? Much less. At higher resolutions the graphics card sets the frame rate, so the gap between two CPUs shrinks — often to nothing. The 1080p figure above is the demanding case, where the CPU is stressed and the difference actually shows.

Performance per dollar

Gaming index divided by the current lowest price — higher is better value. This moves with the market as prices change day to day.

Ryzen 7 9800X3D24.5 / $100
Core i7-12700K22.1 / $100

The Ryzen 7 9800X3D gives about 11% more gaming performance per dollar at today’s prices.

Full platform cost

A CPU’s real cost includes the cheapest in-stock motherboard that can run it and, when the chip doesn’t bundle one, a cooler that can handle it. Here is the lowest-priced complete platform for each, and the gaming performance you get per platform dollar.
