Core i7-9700K vs Core i7-7820X comparison

In our benchmarks, the Core i7-7820X beats the Core i7-9700K in overall performance. Despite this, the Core i7-9700K has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-7820X has more threads. According to our data, the Core i7-9700K and Core i7-7820X have the same clock speed. Despite this, the Core i7-9700K has a slightly higher turbo speed. A Core i7-9700K 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.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
