Intel Core i7-7820HQ vs Intel Core i7-3940XM

Core i7-7820HQ vs Core i7-3940XM benchmarks

According to the hardwareDB Benchmark tool, the Core i7-3940XM is faster than the Core i7-7820HQ. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7820HQ 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 i7-7820HQ. Furthermore, both these CPUs have identical turbo speeds. A Core i7-7820HQ CPU outputs less heat than a Core i7-3940XM CPU because of its 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 i7-7820HQ has more threads than cores. Each physical core is split into multiple threads.
