Intel Xeon E5-2660 vs Intel Xeon E3-1245 v5

Xeon E5-2660 vs Xeon E3-1245 v5 specs and performance

In our benchmarks, the Xeon E5-2660 beats the Xeon E3-1245 v5 in overall performance. Despite this, the Xeon E3-1245 v5 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2660 has significantly more cores with 8 cores compared to the Xeon E3-1245 v5 that has 4 cores. It also has more threads than the Xeon E3-1245 v5. These CPUs have different clock speeds. Indeed, the Xeon E3-1245 v5 has a significantly higher clock speed compared to the Xeon E5-2660. Also, the Xeon E3-1245 v5 has a slightly higher turbo speed. The Xeon E3-1245 v5 outputs less heat than Xeon E5-2660 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Xeon E5-2660 has more threads than cores. Each physical core is split into multiple threads.
