Core i7-6700 vs Xeon E5-1660 v3 benchmarks

According to the hardwareDB Benchmark tool, the Xeon E5-1660 v3 is faster than the Core i7-6700. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6700 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-1660 v3 has significantly more cores with 8 cores compared to the Core i7-6700 that has 4 cores. It also has more threads than the Core i7-6700. These CPUs have different clock speeds. Indeed, the Core i7-6700 has a slightly higher clock speed compared to the Xeon E5-1660 v3. Also, the Core i7-6700 has a slightly higher turbo speed. A Core i7-6700 CPU outputs less heat than a Xeon E5-1660 v3 CPU because of its significantly lower TDP. 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 Core i7-6700 has more threads than cores. Each physical core is split into multiple threads.
