Intel Core i9-10900X vs Intel Core i9-12900H

Core i9-10900X vs Core i9-12900H benchmarks

Our benchmark analysis concludes that the Core i9-12900H performs better than the Core i9-10900X. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-10900X in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-12900H has slightly more cores with 14 cores compared to the Core i9-10900X that has 10 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i9-10900X has a significantly higher clock speed compared to the Core i9-12900H. Despite this, the Core i9-12900H has a slightly higher turbo speed. The Core i9-12900H outputs less heat than Core i9-10900X thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i9-10900X has more threads than cores. Each physical core is split into multiple threads.
