The short answer
The Core i5-14400F is the faster chip for gaming, with the two closely matched on price-to-performance.
- Core i5-14400F is about 9% faster for gaming at 1080p (gaming index 58.0 vs 53.0).
- Core i5-14400F is roughly 45% faster in multi-core work, an edge in rendering, encoding and compiling.
- Core i5-12400F is the cheaper chip right now, by roughly 12%.
- Core i5-12400F delivers about 2% more gaming performance per dollar.
- Core i5-14400F has more cores (10C/16T vs 6C/12T), which helps in heavily threaded workloads.
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 Core i5-12400F gives about 2% 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.
