Intel Xeon E5-2643 vs Intel Xeon E5-2650 v3

Xeon E5-2643 vs Xeon E5-2650 v3 specs and performance

According to the hardwareDB Benchmark tool, the Xeon E5-2650 v3 is faster than the Xeon E5-2643. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2650 v3 has significantly more cores than the Xeon E5-2643. Indeed, the Xeon E5-2650 v3 has 10 cores compared to 4 cores found in the Xeon E5-2643. It also has more threads than the Xeon E5-2643. These CPUs have different clock speeds. Indeed, the Xeon E5-2643 has a significantly higher clock speed compared to the Xeon E5-2650 v3. Also, the Xeon E5-2643 has a slightly higher turbo speed. The Xeon E5-2650 v3 outputs less heat than Xeon E5-2643 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 E5-2643 has more threads than cores. Each physical core is split into multiple threads.
