Core i7-4790 vs Core i7-3840QM benchmarks

Our benchmark analysis concludes that the Core i7-4790 performs better than the Core i7-3840QM. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3840QM in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-4790 has a slightly higher clock speed compared to the Core i7-3840QM. Also, the Core i7-4790 has a slightly higher turbo speed. The Core i7-3840QM outputs less heat than Core i7-4790 thanks to a 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 i7-4790 has more threads than cores. Each physical core is split into multiple threads.
