Intel Core i5-2400 vs Intel Core i7-2820QM

Core i5-2400 vs Core i7-2820QM benchmarks

In our benchmarks, the Core i5-2400 beats the Core i7-2820QM in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2820QM in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-2820QM has more threads. These CPUs have different clock speeds. Indeed, the Core i5-2400 has a slightly higher clock speed compared to the Core i7-2820QM. Furthermore, both these CPUs have identical turbo speeds. The Core i7-2820QM outputs less heat than Core i5-2400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-2400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
