Xeon E5-2643 v2 vs Xeon E5-2667 v2 specs and performance

In our benchmarks, the Xeon E5-2643 v2 beats the Xeon E5-2667 v2 in overall performance. Despite this, the Xeon E5-2667 v2 has the advantage in our gaming benchmark.

With info from our database, we find that the Xeon E5-2667 v2 has slightly more cores with 8 cores whereas the Xeon E5-2643 v2 has 6 cores. It also has more threads than the Xeon E5-2643 v2. Our comparison shows that the Xeon E5-2643 v2 has a slightly higher clock speed compared to the Xeon E5-2667 v2. Despite this, the Xeon E5-2667 v2 has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 v2 has more threads than cores. Each physical core is split into multiple threads.
