Core i3-12100 vs Core i5-10600K
Compare the Core i3-12100 and Core i5-10600K on real gaming and productivity benchmarks, full specifications, live retailer prices and performance-per-dollar, then jump straight to the cheapest in-stock option.
The short answer
The Core i3-12100 is the faster chip for gaming, with the two closely matched on price-to-performance.
- Core i3-12100 is about 16% faster for gaming at 1080p (gaming index 48.0 vs 41.3).
- Core i5-10600K is roughly 30% faster in multi-core work, an edge in rendering, encoding and compiling.
- Core i5-10600K is the cheaper chip right now, by roughly 20%.
- Core i5-10600K delivers about 3% more gaming performance per dollar.
- Core i5-10600K has more cores (6C/12T vs 4C/8T), which helps in heavily threaded workloads.
- Core i3-12100 has a lower TDP (60W vs 125W), 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 Core i5-10600K gives about 3% 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 i5-10600K 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.
