Intel Xeon E5-2630 v2 vs Intel Xeon E5-2665

Xeon E5-2630 v2 vs Xeon E5-2665 specs and performance

Our benchmark analysis concludes that the Xeon E5-2665 performs better than the Xeon E5-2630 v2. Despite this, the Xeon E5-2630 v2 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2665 has slightly more cores with 8 cores compared to the Xeon E5-2630 v2 that has 6 cores. It also has more threads than the Xeon E5-2630 v2. With our hardware info, we find that the Xeon E5-2630 v2 has a slightly higher clock speed than the Xeon E5-2665. Furthermore, both these CPUs have identical turbo speeds. A Xeon E5-2630 v2 CPU outputs less heat than a Xeon E5-2665 CPU because of its 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 E5-2630 v2 has more threads than cores. Each physical core is split into multiple threads.
