Core i5-6400 vs Xeon E5-620 comparison

Our benchmark analysis concludes that the Core i5-6400 performs better 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 but the Xeon E5-620 has more threads. Our comparison shows that the Core i5-6400 has a slightly higher clock speed compared to the Xeon E5-620. Also, the Core i5-6400 has a slightly higher turbo speed. A Core i5-6400 CPU outputs less heat than a Xeon E5-620 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core i5-6400 has more L2 cache than the Xeon E5-620. The Core i5-6400 also has significantly more L3 cache.

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 i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
