The short answer

The Ryzen 9 5900X is the better value, though the Ryzen 7 9800X3D is the faster gaming chip.

  • Ryzen 7 9800X3D is about 70% faster for gaming at 1080p (gaming index 97.0 vs 57.0).
  • Ryzen 7 9800X3D is roughly 12% faster in multi-core work, an edge in rendering, encoding and compiling.
  • Ryzen 9 5900X is the cheaper chip right now, by roughly 85%.
  • Ryzen 9 5900X delivers about 9% more gaming performance per dollar.
  • Ryzen 9 5900X has more cores (12C/24T vs 8C/16T), which helps in heavily threaded workloads.
  • Ryzen 9 5900X has a lower TDP (105W 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 7 9800X3D97.0
Ryzen 9 5900X57.0

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 7 9800X3D24.5 / $100
Ryzen 9 5900X26.6 / $100

The Ryzen 9 5900X gives about 9% 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.
