Intel Xeon E5-1660 vs Intel Xeon E5-2660 v3

Xeon E5-1660 vs Xeon E5-2660 v3 benchmarks

Our benchmark analysis concludes that the Xeon E5-2660 v3 performs better than the Xeon E5-1660. Despite this, the Xeon E5-1660 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2660 v3 has significantly more cores with 10 cores compared to the Xeon E5-1660 that has 6 cores. It also has more threads than the Xeon E5-1660. These CPUs have different clock speeds. Indeed, the Xeon E5-1660 has a slightly higher clock speed compared to the Xeon E5-2660 v3. Also, the Xeon E5-1660 has a slightly higher turbo speed. The Xeon E5-2660 v3 outputs less heat than Xeon E5-1660 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Xeon E5-1660 has more threads than cores. Each physical core is split into multiple threads.
