Intel Core i7-2820QM vs Intel Xeon E5-2420

Core i7-2820QM vs Xeon E5-2420 comparison

Our benchmark analysis concludes that the Core i7-2820QM performs better than the Xeon E5-2420. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2420 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2420 has significantly more cores with 6 cores compared to the Core i7-2820QM that has 4 cores. It also has more threads than the Core i7-2820QM. Our comparison shows that the Core i7-2820QM has a slightly higher clock speed compared to the Xeon E5-2420. Also, the Core i7-2820QM has a slightly higher turbo speed. A Core i7-2820QM CPU outputs less heat than a Xeon E5-2420 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.
