Xeon E5-1660 vs Xeon E5-2643 comparison

According to the hardwareDB Benchmark tool, the Xeon E5-1660 is faster than the Xeon E5-2643. Despite this, the Xeon E5-2643 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-1660 has significantly more cores than the Xeon E5-2643. Indeed, the Xeon E5-1660 has 6 cores compared to 4 cores found in the Xeon E5-2643. It also has more threads than the Xeon E5-2643. Both the Xeon E5-1660 and Xeon E5-2643 have the same clock speed. Despite this, 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.

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 E5-1660 has more threads than cores. Each physical core is split into multiple threads.
