Intel Core i5-8600K vs Intel Xeon E5-2643

Core i5-8600K vs Xeon E5-2643 specs and performance

In our benchmarks, the Core i5-8600K beats the Xeon E5-2643 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8600K has significantly more cores with 6 cores compared to the Xeon E5-2643 that has 4 cores. Despite this, the Xeon E5-2643 has more threads than the Core i5-8600K. These CPUs have different clock speeds. Indeed, the Core i5-8600K has a slightly higher clock speed compared to the Xeon E5-2643. Also, the Core i5-8600K has a slightly higher turbo speed. A Core i5-8600K CPU outputs less heat than a Xeon E5-2643 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. For instance, the Core i5-8600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
