Intel Xeon E5-2470 v2 vs Intel Xeon E5-2665

Xeon E5-2470 v2 vs Xeon E5-2665 comparison

In our benchmarks, the Xeon E5-2470 v2 beats the Xeon E5-2665 in overall performance. Despite this, the Xeon E5-2665 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2470 v2 has slightly more cores than the Xeon E5-2665. Indeed, the Xeon E5-2470 v2 has 10 cores compared to 8 cores found in the Xeon E5-2665. It also has more threads than the Xeon E5-2665. Both the Xeon E5-2470 v2 and Xeon E5-2665 have the same clock speed. Despite this, the Xeon E5-2470 v2 has a slightly higher turbo speed. A Xeon E5-2470 v2 CPU outputs less heat than a Xeon E5-2665 CPU because of its slightly 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 E5-2470 v2 has more threads than cores. Each physical core is split into multiple threads.
