Core i5-8400 vs Ryzen 5 7640HS benchmarks

Our benchmark analysis concludes that the Ryzen 5 7640HS performs better than the Core i5-8400. Despite this, the Core i5-8400 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Ryzen 5 7640HS has more threads. With our hardware info, we find that the Ryzen 5 7640HS has a significantly higher clock speed than the Core i5-8400. Also, the Ryzen 5 7640HS has a slightly higher turbo speed. The Ryzen 5 7640HS outputs less heat than Core i5-8400 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Ryzen 5 7640HS has more L2 cache than the Core i5-8400. The Ryzen 5 7640HS also has significantly more 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. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
