Xeon E5-2643 vs Xeon E3-1505M v6 comparison

Our benchmark analysis concludes that the Xeon E3-1505M v6 performs better than the Xeon E5-2643. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Xeon E5-2643 has a slightly higher clock speed than the Xeon E3-1505M v6. Despite this, the Xeon E3-1505M v6 has a slightly higher turbo speed. The Xeon E3-1505M 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.

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.
