Intel Core i7-9700KF vs Intel Core i7-7820X

Core i7-9700KF vs Core i7-7820X benchmarks

Our benchmark analysis concludes that the Core i7-7820X performs better than the Core i7-9700KF. Despite this, the Core i7-9700KF has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-7820X has more threads. In terms of clock speed, the Core i7-9700KF and Core i7-7820X are identical in this regard. Despite this, the Core i7-9700KF has a slightly higher turbo speed. A Core i7-9700KF CPU outputs less heat than a Core i7-7820X CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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. For instance, the Core i7-9700KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
