Intel Core i7-2820QM vs Intel Core i7-4870HQ

Core i7-2820QM vs Core i7-4870HQ comparison

Our benchmark analysis concludes that the Core i7-4870HQ performs better than the Core i7-2820QM. 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 and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-4870HQ has a slightly higher clock speed compared to the Core i7-2820QM. Also, the Core i7-4870HQ has a slightly higher turbo speed. A Core i7-2820QM CPU outputs less heat than a Core i7-4870HQ CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-2820QM has more threads than cores. Each physical core is split into multiple threads.
