Intel Xeon E3-1275 v3 vs Intel Xeon E5-2660

Xeon E3-1275 v3 vs Xeon E5-2660 comparison

In our benchmarks, the Xeon E5-2660 beats the Xeon E3-1275 v3 in overall performance. Despite this, the Xeon E3-1275 v3 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2660 has significantly more cores than the Xeon E3-1275 v3. Indeed, the Xeon E5-2660 has 8 cores compared to 4 cores found in the Xeon E3-1275 v3. It also has more threads than the Xeon E3-1275 v3. These CPUs have different clock speeds. Indeed, the Xeon E3-1275 v3 has a significantly higher clock speed compared to the Xeon E5-2660. Also, the Xeon E3-1275 v3 has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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.
