Ryzen 9 7945HX vs Ryzen 9 7940HX comparison

According to the hardwareDB Benchmark tool, the Ryzen 9 7940HX is faster than the Ryzen 9 7945HX. Despite this, the Ryzen 9 7945HX 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 9 7945HX has a slightly higher clock speed compared to the Ryzen 9 7940HX. Also, the Ryzen 9 7945HX has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 and L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Ryzen 9 7945HX has more threads than cores. Each physical core is split into multiple threads.
