Xeon E5-2640 vs Xeon E3-1245 v3 specs and performance

In our benchmarks, the Xeon E5-2640 beats the Xeon E3-1245 v3 in overall performance. Despite this, the Xeon E3-1245 v3 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2640 has significantly more cores than the Xeon E3-1245 v3. Indeed, the Xeon E5-2640 has 6 cores compared to 4 cores found in the Xeon E3-1245 v3. It also has more threads than the Xeon E3-1245 v3. Our comparison shows that the Xeon E3-1245 v3 has a slightly higher clock speed compared to the Xeon E5-2640. Also, the Xeon E3-1245 v3 has a slightly higher turbo speed. The Xeon E3-1245 v3 outputs less heat than Xeon E5-2640 thanks to a 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 E5-2640 has more threads than cores. Each physical core is split into multiple threads.
