Ryzen 7 7840HS vs Ryzen 7 7745HX comparison

According to the hardwareDB Benchmark tool, the Ryzen 7 7745HX is faster than the Ryzen 7 7840HS. Despite this, the Ryzen 7 7840HS has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Ryzen 7 7840HS has a slightly higher clock speed compared to the Ryzen 7 7745HX. Furthermore, both these CPUs have identical turbo speeds. A Ryzen 7 7840HS CPU outputs less heat than a Ryzen 7 7745HX CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Ryzen 7 7745HX 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 7 7840HS has more threads than cores. Each physical core is split into multiple threads.
