Intel Core i7-5820K vs Intel Xeon E5-2650 v2

Core i7-5820K vs Xeon E5-2650 v2 comparison

Our benchmark analysis concludes that the Core i7-5820K performs better than the Xeon E5-2650 v2. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2650 v2 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2650 v2 has slightly more cores with 8 cores compared to the Core i7-5820K that has 6 cores. It also has more threads than the Core i7-5820K. With our hardware info, we find that the Core i7-5820K has a slightly higher clock speed than the Xeon E5-2650 v2. Also, the Core i7-5820K has a slightly higher turbo speed. The Xeon E5-2650 v2 outputs less heat than Core i7-5820K thanks to a 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. Indeed, the Core i7-5820K has more threads than cores. Each physical core is split into multiple threads.
