Core i7-7820HQ vs Core i7-4870HQ benchmarks

In our benchmarks, the Core i7-4870HQ beats the Core i7-7820HQ in overall performance. Despite this, the Core i7-7820HQ has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Core i7-7820HQ has a slightly higher clock speed than the Core i7-4870HQ. Also, the Core i7-7820HQ has a slightly higher turbo speed. A Core i7-7820HQ 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.

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. Indeed, the Core i7-7820HQ has more threads than cores. Each physical core is split into multiple threads.
