Intel Core i7-3770K vs Intel Core i7-3940XM

Core i7-3770K vs Core i7-3940XM comparison

In our benchmarks, the Core i7-3770K beats the Core i7-3940XM in overall performance. 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 i7-3770K has a slightly higher clock speed compared to the Core i7-3940XM. In addition, both chips have the same turbo speed. The Core i7-3940XM outputs less heat than Core i7-3770K 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 i7-3770K has more threads than cores. Each physical core is split into multiple threads.
