Intel Xeon E5-2640 vs Intel Xeon E3-1231 v3

Xeon E5-2640 vs Xeon E3-1231 v3 benchmarks

In our benchmarks, the Xeon E5-2640 beats the Xeon E3-1231 v3 in overall performance. Despite this, the Xeon E3-1231 v3 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2640 has significantly more cores than the Xeon E3-1231 v3. Indeed, the Xeon E5-2640 has 6 cores compared to 4 cores found in the Xeon E3-1231 v3. It also has more threads than the Xeon E3-1231 v3. With our hardware info, we find that the Xeon E3-1231 v3 has a slightly higher clock speed than the Xeon E5-2640. Also, the Xeon E3-1231 v3 has a slightly higher turbo speed. The Xeon E3-1231 v3 outputs less heat than Xeon E5-2640 thanks to a 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 E5-2640 has more threads than cores. Each physical core is split into multiple threads.
