Core i7-4770K vs Xeon E5-1620 comparison

Our benchmark analysis concludes that the Xeon E5-1620 performs better than the Core i7-4770K. Despite this, the Core i7-4770K has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Xeon E5-1620 has a slightly higher clock speed compared to the Core i7-4770K. Despite this, the Core i7-4770K has a slightly higher turbo speed. A Core i7-4770K CPU outputs less heat than a Xeon E5-1620 CPU because of its 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 i7-4770K has more threads than cores. Each physical core is split into multiple threads.
