In terms of the number of cores of each of these CPUs, the Core i9-7940X has slightly more cores than the Xeon E5-2666 v3. Indeed, the Core i9-7940X has 14 cores compared to 10 cores found in the Xeon E5-2666 v3. It also has more threads than the Xeon E5-2666 v3. These CPUs have different clock speeds. Indeed, the Core i9-7940X has a slightly higher clock speed compared to the Xeon E5-2666 v3.

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 i9-7940X has more threads than cores. Each physical core is split into multiple threads.
