Intel Core i7-11700K vs Intel Core i7-9800X

Core i7-11700K vs Core i7-9800X specs and performance

In our benchmarks, the Core i7-11700K beats the Core i7-9800X in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-9800X in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i7-9800X has a slightly higher clock speed compared to the Core i7-11700K. Despite this, the Core i7-11700K has a slightly higher turbo speed. A Core i7-11700K CPU outputs less heat than a Core i7-9800X CPU because of its slightly 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. Indeed, the Core i7-11700K has more threads than cores. Each physical core is split into multiple threads.
