Intel Core i7-9700K vs Intel Xeon E5-2666 v3

Core i7-9700K vs Xeon E5-2666 v3 specs and performance

Our benchmark analysis concludes that the Core i7-9700K performs better than the Xeon E5-2666 v3. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2666 v3 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2666 v3 has slightly more cores than the Core i7-9700K. Indeed, the Xeon E5-2666 v3 has 10 cores compared to 8 cores found in the Core i7-9700K. It also has more threads than the Core i7-9700K. With our hardware info, we find that the Core i7-9700K has a slightly higher clock speed than the Xeon E5-2666 v3. The cache sizes of these CPUs are different. Indeed, the Xeon E5-2666 v3 has slightly more L2 cache than the Core i7-9700K. The Xeon E5-2666 v3 also has significantly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
