Core i7-975 vs Xeon E5-620 comparison

According to the hardwareDB Benchmark tool, the Core i7-975 is faster than the Xeon E5-620. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-620 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 i7-975 has a slightly higher clock speed than the Xeon E5-620. Also, the Core i7-975 has a slightly higher turbo speed. The Xeon E5-620 outputs less heat than Core i7-975 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 i7-975 has more threads than cores. Each physical core is split into multiple threads.
