Ryzen 7 4700U vs Ryzen 9 7945HX comparison

In our benchmarks, the Ryzen 9 7945HX beats the Ryzen 7 4700U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 7 4700U in all gaming tests too.

With info from our database, we find that the Ryzen 9 7945HX has significantly more cores with 16 cores whereas the Ryzen 7 4700U has 8 cores. It also has more threads than the Ryzen 7 4700U. Our comparison shows that the Ryzen 9 7945HX has a slightly higher clock speed compared to the Ryzen 7 4700U. Also, the Ryzen 9 7945HX has a slightly higher turbo speed. A Ryzen 7 4700U CPU outputs less heat than a Ryzen 9 7945HX CPU because of its 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 7945HX has significantly more L2 cache than the Ryzen 7 4700U. The Ryzen 9 7945HX 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. For instance, the Ryzen 7 4700U has the same number of threads as cores. This means the the CPU does not support hyperthreading.
