Core i7-8086K vs Xeon E5-2666 v3 comparison

Our benchmark analysis concludes that the Xeon E5-2666 v3 performs better than the Core i7-8086K. Despite this, the Core i7-8086K has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Xeon E5-2666 v3 has significantly more cores than the Core i7-8086K. Indeed, the Xeon E5-2666 v3 has 10 cores compared to 6 cores found in the Core i7-8086K. It also has more threads than the Core i7-8086K. These CPUs have different clock speeds. Indeed, the Core i7-8086K has a slightly higher clock speed compared to the Xeon E5-2666 v3. The cache sizes of these CPUs are different. Indeed, the Xeon E5-2666 v3 has significantly more L2 cache than the Core i7-8086K. The Xeon E5-2666 v3 also has significantly more L3 cache.

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. Indeed, the Core i7-8086K has more threads than cores. Each physical core is split into multiple threads.
