Xeon E3-1240 v3 vs Xeon E3-1280 v3 benchmarks

In our benchmarks, the Xeon E3-1280 v3 beats the Xeon E3-1240 v3 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E3-1240 v3 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. With our hardware info, we find that the Xeon E3-1280 v3 has a slightly higher clock speed than the Xeon E3-1240 v3. Also, the Xeon E3-1280 v3 has a slightly higher turbo speed. A Xeon E3-1240 v3 CPU outputs less heat than a Xeon E3-1280 v3 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 E3-1240 v3 has more threads than cores. Each physical core is split into multiple threads.
