Intel Core i7-8665U vs Intel Core i7-2700K

Core i7-8665U vs Core i7-2700K specs and performance

In our benchmarks, the Core i7-8665U beats the Core i7-2700K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2700K in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i7-2700K has a significantly higher clock speed than the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. A Core i7-8665U CPU outputs less heat than a Core i7-2700K 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 i7-8665U has more threads than cores. Each physical core is split into multiple threads.
