The short answer

The Ryzen 9 9950X is the better value, though the Core i9-13900KS is the faster gaming chip.

  • Gaming performance is effectively a wash at 1080p (index 76.9 vs 76.8); at 1440p and 4K the GPU sets the frame rate, so the gap shrinks further.
  • Ryzen 9 9950X is roughly 8% faster in multi-core work, an edge in rendering, encoding and compiling.
  • Ryzen 9 9950X is the cheaper chip right now, by roughly 42%.
  • Ryzen 9 9950X delivers about 42% more gaming performance per dollar.
  • Core i9-13900KS has more cores (24C/32T vs 16C/32T), which helps in heavily threaded workloads.
  • Core i9-13900KS has a lower TDP (150W vs 170W), 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 9950X76.9
Core i9-13900KS76.8

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 9 9950X15.4 / $100
Core i9-13900KS10.9 / $100

The Ryzen 9 9950X gives about 42% 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.
