Intel Xeon E5-2643 v2 vs Intel Core i7-1255U

Xeon E5-2643 v2 vs Core i7-1255U specs and performance

Our benchmark analysis concludes that the Core i7-1255U performs better than the Xeon E5-2643 v2. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 v2 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-1255U has significantly more cores than the Xeon E5-2643 v2. Indeed, the Core i7-1255U has 10 cores compared to 6 cores found in the Xeon E5-2643 v2. But they both have the same number of threads. Our comparison shows that the Xeon E5-2643 v2 has a significantly higher clock speed compared to the Core i7-1255U. Despite this, the Core i7-1255U has a slightly higher turbo speed. The Core i7-1255U outputs less heat than Xeon E5-2643 v2 thanks to a 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 Xeon E5-2643 v2 has more threads than cores. Each physical core is split into multiple threads.
