Intel Core i7-2820QM vs Intel Xeon E5-620

Core i7-2820QM vs Xeon E5-620 benchmarks

Our benchmark analysis concludes that the Xeon E5-620 performs better than the Core i7-2820QM. Despite this, the Core i7-2820QM 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. These CPUs have different clock speeds. Indeed, the Xeon E5-620 has a slightly higher clock speed compared to the Core i7-2820QM. Despite this, the Core i7-2820QM has a slightly higher turbo speed. A Core i7-2820QM CPU outputs less heat than a Xeon E5-620 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i7-2820QM has more threads than cores. Each physical core is split into multiple threads.
