Intel Core i7-1355U vs Intel Core Ultra 5 135U

Core i7-1355U vs Core Ultra 5 135U benchmarks

According to the hardwareDB Benchmark tool, the Core Ultra 5 135U is faster than the Core i7-1355U. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-1355U in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core Ultra 5 135U has slightly more cores with 12 cores compared to the Core i7-1355U that has 10 cores. It also has more threads than the Core i7-1355U. These CPUs have different clock speeds. Indeed, the Core Ultra 5 135U has a slightly higher clock speed compared to the Core i7-1355U. Despite this, the Core i7-1355U has a slightly higher turbo speed. In terms of cache, the Core Ultra 5 135U has significantly more L2 cache when compared to the Core i7-1355U. 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 i7-1355U has more threads than cores. Each physical core is split into multiple threads.
