Core i9-12900HX vs Ryzen 9 7900X comparison

According to the hardwareDB Benchmark tool, the Ryzen 9 7900X is faster than the Core i9-12900HX. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-12900HX in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-12900HX has slightly more cores with 16 cores compared to the Ryzen 9 7900X that has 12 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 7900X has a significantly higher clock speed compared to the Core i9-12900HX. Also, the Ryzen 9 7900X has a slightly higher turbo speed. A Core i9-12900HX CPU outputs less heat than a Ryzen 9 7900X CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Ryzen 9 7900X has more L2 cache than the Core i9-12900HX. The Ryzen 9 7900X also has significantly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i9-12900HX has more threads than cores. Each physical core is split into multiple threads.
