Intel Core i7-5820K vs Intel Xeon E5-1660 v3

Core i7-5820K vs Xeon E5-1660 v3 comparison

According to the hardwareDB Benchmark tool, the Xeon E5-1660 v3 is faster than the Core i7-5820K. Despite this, the Core i7-5820K has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-1660 v3 has slightly more cores with 8 cores compared to the Core i7-5820K that has 6 cores. It also has more threads than the Core i7-5820K. These CPUs have different clock speeds. Indeed, the Core i7-5820K has a slightly higher clock speed compared to the Xeon E5-1660 v3. Also, the Core i7-5820K 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 Core i7-5820K has more threads than cores. Each physical core is split into multiple threads.
