Intel Core i7-7660U vs Intel Xeon E5-2420 v2

Core i7-7660U vs Xeon E5-2420 v2 specs and performance

According to the hardwareDB Benchmark tool, the Xeon E5-2420 v2 is faster than the Core i7-7660U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7660U in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Xeon E5-2420 v2 has significantly more cores than the Core i7-7660U. Indeed, the Xeon E5-2420 v2 has 6 cores compared to 2 cores found in the Core i7-7660U. It also has more threads than the Core i7-7660U. Our comparison shows that the Core i7-7660U has a slightly higher clock speed compared to the Xeon E5-2420 v2. Also, the Core i7-7660U has a significantly higher turbo speed. A Core i7-7660U CPU outputs less heat than a Xeon E5-2420 v2 CPU because of its significantly 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. Indeed, the Core i7-7660U has more threads than cores. Each physical core is split into multiple threads.
