Xeon E5-2643 vs Xeon E3-1535M v6 specs and performance

Our benchmark analysis concludes that the Xeon E5-2643 performs better than the Xeon E3-1535M v6. Despite this, the Xeon E3-1535M v6 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E5-2643 has a slightly higher clock speed compared to the Xeon E3-1535M v6. Despite this, the Xeon E3-1535M v6 has a slightly higher turbo speed. The Xeon E3-1535M v6 outputs less heat than Xeon E5-2643 thanks to a 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 E5-2643 has more threads than cores. Each physical core is split into multiple threads.
