Ryzen 9 8940HX vs Ryzen 7 5800XT comparison

Our benchmark analysis concludes that the Ryzen 9 8940HX performs better than the Ryzen 7 5800XT. Despite this, the Ryzen 7 5800XT has the advantage in our gaming benchmark.

With info from our database, we find that the Ryzen 9 8940HX has significantly more cores with 16 cores whereas the Ryzen 7 5800XT has 8 cores. It also has more threads than the Ryzen 7 5800XT. With our hardware info, we find that the Ryzen 7 5800XT has a slightly higher clock speed than the Ryzen 9 8940HX. Despite this, the Ryzen 9 8940HX has a slightly higher turbo speed. A Ryzen 9 8940HX CPU outputs less heat than a Ryzen 7 5800XT CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Ryzen 7 5800XT also has significantly more L3 cache.

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 8940HX has more threads than cores. Each physical core is split into multiple threads.
