Core i7-1255U vs Core i5-1235U benchmarks
Our benchmark analysis concludes that the Core i7-1255U performs better than the Core i5-1235U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-1235U in all gaming tests too.
When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-1255U has a slightly higher clock speed compared to the Core i5-1235U. Also, the Core i7-1255U has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i7-1255U has significantly more L2 cache when compared to the Core i5-1235U. 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.
