Intel Core i7-9700K vs Intel Core i9-9940X

Core i7-9700K vs Core i9-9940X specs and performance

According to the hardwareDB Benchmark tool, the Core i9-9940X is faster than the Core i7-9700K. Despite this, the Core i7-9700K has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i9-9940X has significantly more cores than the Core i7-9700K. Indeed, the Core i9-9940X has 14 cores compared to 8 cores found in the Core i7-9700K. It also has more threads than the Core i7-9700K. With our hardware info, we find that the Core i7-9700K has a slightly higher clock speed than the Core i9-9940X. Also, the Core i7-9700K has a slightly higher turbo speed. A Core i7-9700K CPU outputs less heat than a Core i9-9940X 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 i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
