Xeon E5-2643 vs Xeon E3-1245 v5 comparison

In our benchmarks, the Xeon E3-1245 v5 beats the Xeon E5-2643 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Xeon E3-1245 v5 has a slightly higher clock speed compared to the Xeon E5-2643. Also, the Xeon E3-1245 v5 has a slightly higher turbo speed. The Xeon E3-1245 v5 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.
