The short answer

The Ryzen 7 9700X is the better value, though the Ryzen 9 9900X is the faster gaming chip.

  • Gaming performance is effectively a wash at 1080p (index 73.9 vs 73.0); at 1440p and 4K the GPU sets the frame rate, so the gap shrinks further.
  • Ryzen 9 9900X is roughly 38% faster in multi-core work, an edge in rendering, encoding and compiling.
  • Ryzen 7 9700X is the cheaper chip right now, by roughly 13%.
  • Ryzen 7 9700X delivers about 11% more gaming performance per dollar.
  • Ryzen 9 9900X has more cores (12C/24T vs 8C/16T), which helps in heavily threaded workloads.
  • Ryzen 7 9700X has a lower TDP (65W vs 120W), so it runs cooler and is easier to cool quietly.

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 9 9900X73.9
Ryzen 7 9700X73.0

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 9 9900X22.3 / $100
Ryzen 7 9700X24.7 / $100

The Ryzen 7 9700X 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.
