Ryzen 9 7900X vs Core Ultra 9 275HX specs and performance

Our benchmark analysis concludes that the Ryzen 9 7900X performs better than the Core Ultra 9 275HX. Despite this, the Core Ultra 9 275HX has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core Ultra 9 275HX has significantly more cores with 24 cores compared to the Ryzen 9 7900X that has 12 cores. But they both have the same number of threads. With our hardware info, we find that the Ryzen 9 7900X has a significantly higher clock speed than the Core Ultra 9 275HX. In terms of cache, the Core Ultra 9 275HX has significantly more L2 cache when compared to the Ryzen 9 7900X. Despite this, the Ryzen 9 7900X has significantly more L3 cache compared to the Core Ultra 9 275HX.

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 Ryzen 9 7900X has more threads than cores. Each physical core is split into multiple threads.
