- Ryzen 7 9800X3D delivers about 109% more gaming performance per dollar.
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 7 9800X3D gives about 109% more gaming performance per dollar at today’s prices.
Full platform cost
A complete-platform price needs a live CPU price and an in-stock compatible motherboard on both sides. We can’t build one for Core i7-11700K right now, which is common for older sockets like AM4 where we don’t track current boards. The gaming, value and specs comparisons still apply.

Efficiency
Gaming performance per watt (gaming index per 100W of TDP) — higher means more frames for the heat and power.
