Xeon E3-1275 v3 vs Xeon E5-2643 benchmarks

According to the hardwareDB Benchmark tool, the Xeon E3-1275 v3 is faster than the Xeon E5-2643. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2643 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon E3-1275 v3 has a slightly higher clock speed compared to the Xeon E5-2643. Also, the Xeon E3-1275 v3 has a slightly higher turbo speed. A Xeon E3-1275 v3 CPU outputs less heat than a Xeon E5-2643 CPU because of its 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 E3-1275 v3 has more threads than cores. Each physical core is split into multiple threads.
