Core i7-7700K vs Core i7-9750HF specs and performance

According to the hardwareDB Benchmark tool, the Core i7-9750HF is faster than the Core i7-7700K. Despite this, the Core i7-7700K has the advantage in our gaming benchmark.

With info from our database, we find that the Core i7-9750HF has significantly more cores with 6 cores whereas the Core i7-7700K has 4 cores. It also has more threads than the Core i7-7700K. Our comparison shows that the Core i7-7700K has a significantly higher clock speed compared to the Core i7-9750HF. In terms of cache, the Core i7-9750HF has significantly more L2 cache when compared to the Core i7-7700K. The Core i7-9750HF 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 Core i7-7700K has more threads than cores. Each physical core is split into multiple threads.
