Ryzen 9 7940HS vs Ryzen 7 7840U benchmarks

In our benchmarks, the Ryzen 9 7940HS beats the Ryzen 7 7840U in overall performance. Despite this, the Ryzen 7 7840U has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Ryzen 9 7940HS has a slightly higher clock speed than the Ryzen 7 7840U. Also, the Ryzen 9 7940HS has a slightly higher turbo speed. The Ryzen 7 7840U outputs less heat than Ryzen 9 7940HS thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches and L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Ryzen 9 7940HS has more threads than cores. Each physical core is split into multiple threads.
