Intel Core i7-3820 vs Intel Xeon E5-620

Core i7-3820 vs Xeon E5-620 specs and performance

In our benchmarks, the Xeon E5-620 beats the Core i7-3820 in overall performance. Despite this, the Core i7-3820 has the advantage in our gaming benchmark.

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 i7-3820 has a slightly higher clock speed than the Xeon E5-620. Also, the Core i7-3820 has a much higher turbo speed. The Xeon E5-620 outputs less heat than Core i7-3820 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 i7-3820 has more threads than cores. Each physical core is split into multiple threads.
