Core i7-3820QM vs Core i7-870 benchmarks

Our benchmark analysis concludes that the Core i7-3820QM performs better than the Core i7-870. Despite this, the Core i7-870 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i7-870 has a slightly higher clock speed than the Core i7-3820QM. Despite this, the Core i7-3820QM has a slightly higher turbo speed. A Core i7-3820QM CPU outputs less heat than a Core i7-870 CPU because of its significantly 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 i7-3820QM has more threads than cores. Each physical core is split into multiple threads.
