Core i7-12700K vs Core i9-12900K specs and performance

According to the hardwareDB Benchmark tool, the Core i9-12900K is faster than the Core i7-12700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-12700K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i9-12900K has slightly more cores than the Core i7-12700K. Indeed, the Core i9-12900K has 16 cores compared to 12 cores found in the Core i7-12700K. It also has more threads than the Core i7-12700K. These CPUs have different clock speeds. Indeed, the Core i7-12700K has a slightly higher clock speed compared to the Core i9-12900K. Despite this, the Core i9-12900K has a slightly higher turbo speed. A Core i7-12700K CPU outputs less heat than a Core i9-12900K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i7-12700K has more threads than cores. Each physical core is split into multiple threads.
