Core i7-3820QM vs Xeon E5-2643 benchmarks

In our benchmarks, the Xeon E5-2643 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.

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 Xeon E5-2643 has a slightly higher clock speed than the Core i7-3820QM. Despite this, the Core i7-3820QM has a slightly higher turbo speed. A Core i7-3820QM CPU outputs less heat than a Xeon E5-2643 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 i7-3820QM has more threads than cores. Each physical core is split into multiple threads.
