Core i9-12900KF vs Ryzen 9 7900 comparison

Our benchmark analysis concludes that the Ryzen 9 7900 performs better than the Core i9-12900KF. Despite this, the Core i9-12900KF has the advantage in our gaming benchmark.

With info from our database, we find that the Core i9-12900KF has slightly more cores with 16 cores whereas the Ryzen 9 7900 has 12 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 7900 has a slightly higher clock speed compared to the Core i9-12900KF.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i9-12900KF has more threads than cores. Each physical core is split into multiple threads.
