Core i7-7820X vs Core i9-11900H specs and performance

In our benchmarks, the Core i7-7820X beats the Core i9-11900H in overall performance. Despite this, the Core i9-11900H 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. These CPUs have different clock speeds. Indeed, the Core i7-7820X has a significantly higher clock speed compared to the Core i9-11900H. Despite this, the Core i9-11900H has a slightly higher turbo speed. The Core i9-11900H outputs less heat than Core i7-7820X thanks to a 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 i7-7820X has more threads than cores. Each physical core is split into multiple threads.
