Core i7-9700K vs Core i9-7900X benchmarks

Our benchmark analysis concludes that the Core i9-7900X performs better than the Core i7-9700K. Despite this, the Core i7-9700K has the advantage in our gaming benchmark.

With info from our database, we find that the Core i9-7900X has slightly more cores with 10 cores whereas the Core i7-9700K has 8 cores. 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 i9-7900X. Also, the Core i7-9700K has a slightly higher turbo speed. A Core i7-9700K CPU outputs less heat than a Core i9-7900X CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
