Core i7-8700K vs Ryzen 5 7640HS comparison

According to the hardwareDB Benchmark tool, the Ryzen 5 7640HS is faster than the Core i7-8700K. Despite this, the Core i7-8700K 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. These CPUs have different clock speeds. Indeed, the Ryzen 5 7640HS has a slightly higher clock speed compared to the Core i7-8700K. Also, the Ryzen 5 7640HS has a slightly higher turbo speed. The Ryzen 5 7640HS outputs less heat than Core i7-8700K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 5 7640HS has significantly more L2 cache when compared to the Core i7-8700K. The Ryzen 5 7640HS also has slightly 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. Indeed, the Core i7-8700K has more threads than cores. Each physical core is split into multiple threads.
