Intel Core i7-8700K vs Intel Core i7-9700K

Core i7-8700K vs Core i7-9700K comparison

Our benchmark analysis concludes that the Core i7-9700K performs better than the Core i7-8700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8700K in all gaming tests too.

With info from our database, we find that the Core i7-9700K has slightly more cores with 8 cores whereas the Core i7-8700K has 6 cores. Despite this, the Core i7-8700K has more threads than the Core i7-9700K. With our hardware info, we find that the Core i7-8700K has a slightly higher clock speed than the Core i7-9700K. Despite this, the Core i7-9700K 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. The info from our database shows that the Core i7-9700K has more L2 cache than the Core i7-8700K. However, both these chips have the same amount of 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 i7-8700K has more threads than cores. Each physical core is split into multiple threads.
