Intel Xeon E5-1660 vs Intel Xeon X5647

Xeon E5-1660 vs Xeon X5647 specs and performance

Our benchmark analysis concludes that the Xeon X5647 performs better than the Xeon E5-1660. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-1660 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-1660 has significantly more cores with 6 cores compared to the Xeon X5647 that has 4 cores. It also has more threads than the Xeon X5647. Our comparison shows that the Xeon E5-1660 has a slightly higher clock speed compared to the Xeon X5647. Also, the Xeon E5-1660 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.

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.
