Core i7-8559U vs Core i7-9850H comparison

In our benchmarks, the Core i7-9850H beats the Core i7-8559U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8559U in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-9850H has significantly more cores with 6 cores compared to the Core i7-8559U that has 4 cores. It also has more threads than the Core i7-8559U. These CPUs have different clock speeds. Indeed, the Core i7-8559U has a slightly higher clock speed compared to the Core i7-9850H. Despite this, the Core i7-9850H has a slightly higher turbo speed. A Core i7-8559U CPU outputs less heat than a Core i7-9850H CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i7-9850H has significantly more L2 cache than the Core i7-8559U. The Core i7-9850H also has significantly more L3 cache.

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 i7-8559U has more threads than cores. Each physical core is split into multiple threads.
