Intel Core i7-3820QM vs Intel Xeon E5-520

Core i7-3820QM vs Xeon E5-520 comparison

In our benchmarks, the Xeon E5-520 beats the Core i7-3820QM in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3820QM in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i7-3820QM has more threads. With our hardware info, we find that the Core i7-3820QM has a slightly higher clock speed than the Xeon E5-520. Also, the Core i7-3820QM has a significantly higher turbo speed. A Core i7-3820QM CPU outputs less heat than a Xeon E5-520 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 i7-3820QM has more threads than cores. Each physical core is split into multiple threads.
