Intel Xeon E5-2640 v3 vs Intel Xeon E5-2643

Xeon E5-2640 v3 vs Xeon E5-2643 comparison

According to the hardwareDB Benchmark tool, the Xeon E5-2640 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 E5-2640 v3 has significantly more cores than the Xeon E5-2643. Indeed, the Xeon E5-2640 v3 has 8 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 slightly higher clock speed compared to the Xeon E5-2640 v3. Also, the Xeon E5-2643 has a slightly higher turbo speed. A Xeon E5-2640 v3 CPU outputs less heat than a Xeon E5-2643 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 E5-2640 v3 has more threads than cores. Each physical core is split into multiple threads.
