Xeon E5-2640 vs Xeon E3-1280 v3 benchmarks

Our benchmark analysis concludes that the Xeon E5-2640 performs better than the Xeon E3-1280 v3. Despite this, the Xeon E3-1280 v3 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2640 has significantly more cores with 6 cores compared to the Xeon E3-1280 v3 that has 4 cores. It also has more threads than the Xeon E3-1280 v3. Our comparison shows that the Xeon E3-1280 v3 has a significantly higher clock speed compared to the Xeon E5-2640. Also, the Xeon E3-1280 v3 has a slightly higher turbo speed. The Xeon E3-1280 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.

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 E5-2640 has more threads than cores. Each physical core is split into multiple threads.
