Core i9-12900KS vs Ryzen 9 9900X comparison

According to the hardwareDB Benchmark tool, the Ryzen 9 9900X is faster than the Core i9-12900KS. Despite this, the Core i9-12900KS has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i9-12900KS has slightly more cores than the Ryzen 9 9900X. Indeed, the Core i9-12900KS has 16 cores compared to 12 cores found in the Ryzen 9 9900X. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 9900X has a slightly higher clock speed compared to the Core i9-12900KS. Also, the Ryzen 9 9900X has a slightly higher turbo speed. The Ryzen 9 9900X outputs less heat than Core i9-12900KS thanks to a 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 i9-12900KS has more threads than cores. Each physical core is split into multiple threads.
