Intel Core i7-7820HQ vs Intel Core i3-1215U

Core i7-7820HQ vs Core i3-1215U benchmarks

According to the hardwareDB Benchmark tool, the Core i3-1215U 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.

In terms of the number of cores of each of these CPUs, the Core i3-1215U has significantly more cores than the Core i7-7820HQ. Indeed, the Core i3-1215U has 6 cores compared to 4 cores found in the Core i7-7820HQ. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-7820HQ has a significantly higher clock speed compared to the Core i3-1215U. Despite this, the Core i3-1215U has a slightly higher turbo speed. The Core i3-1215U outputs less heat than Core i7-7820HQ 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 i7-7820HQ has more threads than cores. Each physical core is split into multiple threads.
