Intel Xeon E5-2670 v3 vs Intel Core i5-1245U

Xeon E5-2670 v3 vs Core i5-1245U comparison

In our benchmarks, the Xeon E5-2670 v3 beats the Core i5-1245U in overall performance. Despite this, the Core i5-1245U has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2670 v3 has slightly more cores with 12 cores compared to the Core i5-1245U that has 10 cores. It also has more threads than the Core i5-1245U. With our hardware info, we find that the Xeon E5-2670 v3 has a significantly higher clock speed than the Core i5-1245U. Despite this, the Core i5-1245U has a slightly higher turbo speed. The Core i5-1245U outputs less heat than Xeon E5-2670 v3 thanks to a 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 Xeon E5-2670 v3 has more threads than cores. Each physical core is split into multiple threads.
