Intel Core i7-8665U vs Intel Core i7-8850H

Core i7-8665U vs Core i7-8850H comparison

In our benchmarks, the Core i7-8850H beats the Core i7-8665U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8665U in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-8850H has significantly more cores with 6 cores compared to the Core i7-8665U that has 4 cores. It also has more threads than the Core i7-8665U. These CPUs have different clock speeds. Indeed, the Core i7-8850H has a slightly higher clock speed compared to the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. A Core i7-8665U CPU outputs less heat than a Core i7-8850H CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i7-8665U has more threads than cores. Each physical core is split into multiple threads.
