The short answer
The Ryzen 9 9900X is the better value, though the Ryzen 9 9950X is the faster gaming chip.
- Ryzen 9 9950X is about 4% faster for gaming at 1080p (gaming index 76.9 vs 73.9).
- Ryzen 9 9950X is roughly 28% faster in multi-core work, an edge in rendering, encoding and compiling.
- Ryzen 9 9900X is the cheaper chip right now, by roughly 38%.
- Ryzen 9 9900X delivers about 33% more gaming performance per dollar.
- Ryzen 9 9950X has more cores (16C/32T vs 12C/24T), which helps in heavily threaded workloads.
- Ryzen 9 9900X has a lower TDP (120W 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.
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.
The Ryzen 9 9900X gives about 33% 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.
