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

Core i7-3770S vs Core i7-3940XM benchmarks

According to the hardwareDB Benchmark tool, the Core i7-3940XM is faster than the Core i7-3770S. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3770S in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Core i7-3940XM has a slightly higher clock speed than the Core i7-3770S. Furthermore, both these CPUs have identical turbo speeds. The Core i7-3940XM outputs less heat than Core i7-3770S 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 i7-3770S has more threads than cores. Each physical core is split into multiple threads.
