Core i7-1255U vs Core i7-9750HF comparison

Our benchmark analysis concludes that the Core i7-9750HF performs better than the Core i7-1255U. Despite this, the Core i7-1255U has the advantage in our gaming benchmark.

With info from our database, we find that the Core i7-1255U has significantly more cores with 10 cores whereas the Core i7-9750HF has 6 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-9750HF has a significantly higher clock speed compared to the Core i7-1255U. The info from our database shows that the Core i7-1255U has more L2 cache than the Core i7-9750HF. However, both these chips have the same amount of L3 cache.

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 i7-1255U has more threads than cores. Each physical core is split into multiple threads.
