AMD Ryzen 9 3900XT vs Intel Core i7-12800HX

Ryzen 9 3900XT vs Core i7-12800HX comparison

Our benchmark analysis concludes that the Core i7-12800HX performs better than the Ryzen 9 3900XT. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 3900XT in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-12800HX has slightly more cores with 16 cores compared to the Ryzen 9 3900XT that has 12 cores. But they both have the same number of threads. Our comparison shows that the Ryzen 9 3900XT has a significantly higher clock speed compared to the Core i7-12800HX. Despite this, the Core i7-12800HX has a slightly higher turbo speed. The Core i7-12800HX outputs less heat than Ryzen 9 3900XT thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Ryzen 9 3900XT has significantly more L2 cache than the Core i7-12800HX. The Ryzen 9 3900XT 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 Ryzen 9 3900XT has more threads than cores. Each physical core is split into multiple threads.
