Intel Core i7-3820 vs Intel Xeon E3-1220 v3

Core i7-3820 vs Xeon E3-1220 v3 benchmarks

Our benchmark analysis concludes that the Core i7-3820 performs better than the Xeon E3-1220 v3. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E3-1220 v3 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-3820 has more threads. These CPUs have different clock speeds. Indeed, the Core i7-3820 has a slightly higher clock speed compared to the Xeon E3-1220 v3. Also, the Core i7-3820 has a slightly higher turbo speed. The Xeon E3-1220 v3 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.
