Intel Core i7-4790S vs Intel Core i7-3940XM

Core i7-4790S vs Core i7-3940XM specs and performance

Our benchmark analysis concludes that the Core i7-4790S performs better than the Core i7-3940XM. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3940XM in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-3940XM has a slightly higher clock speed compared to the Core i7-4790S. Despite this, the Core i7-4790S has a slightly higher turbo speed. The Core i7-3940XM outputs less heat than Core i7-4790S thanks to a slightly 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 i7-4790S has more threads than cores. Each physical core is split into multiple threads.
