Intel Core i7-1255U vs Intel Core i7-1355U

Core i7-1255U vs Core i7-1355U benchmarks

In our benchmarks, the Core i7-1255U beats the Core i7-1355U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-1355U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Both the Core i7-1255U and Core i7-1355U have the same clock speed. Despite this, the Core i7-1355U has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core i7-1355U has significantly more L2 cache than the Core i7-1255U. 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.
