Core i5-6600K vs Xeon E3-1275 v3 comparison

According to the hardwareDB Benchmark tool, the Xeon E3-1275 v3 is faster than the Core i5-6600K. Despite this, the Core i5-6600K has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Xeon E3-1275 v3 has more threads. According to our data, the Core i5-6600K and Xeon E3-1275 v3 have the same clock speed. In addition, both chips have the same turbo speed. A Core i5-6600K CPU outputs less heat than a Xeon E3-1275 v3 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
