Core i7-2700K vs Xeon E5-2643 comparison

Our benchmark analysis concludes that the Xeon E5-2643 performs better than the Core i7-2700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2700K in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i7-2700K has a slightly higher clock speed than the Xeon E5-2643. Also, the Core i7-2700K has a slightly higher turbo speed. A Core i7-2700K 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.

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. Indeed, the Core i7-2700K has more threads than cores. Each physical core is split into multiple threads.
