Intel Xeon E5-2643 vs Intel Xeon E5-2670 v2

Xeon E5-2643 vs Xeon E5-2670 v2 benchmarks

Our benchmark analysis concludes that the Xeon E5-2670 v2 performs better than the Xeon E5-2643. Despite this, the Xeon E5-2643 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2670 v2 has significantly more cores than the Xeon E5-2643. Indeed, the Xeon E5-2670 v2 has 10 cores compared to 4 cores found in the Xeon E5-2643. It also has more threads than the Xeon E5-2643. With our hardware info, we find that the Xeon E5-2643 has a slightly higher clock speed than the Xeon E5-2670 v2. Also, the Xeon E5-2643 has a slightly higher turbo speed. The Xeon E5-2670 v2 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.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Xeon E5-2643 has more threads than cores. Each physical core is split into multiple threads.
