Intel Core i5-1240P vs Intel Core i7-1355U

Core i5-1240P vs Core i7-1355U comparison

In our benchmarks, the Core i5-1240P 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.

In terms of the number of cores of each of these CPUs, the Core i5-1240P has slightly more cores than the Core i7-1355U. Indeed, the Core i5-1240P has 12 cores compared to 10 cores found in the Core i7-1355U. It also has more threads than the Core i7-1355U. Both the Core i5-1240P 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 slightly more L2 cache than the Core i5-1240P. However, both these chips have the same amount of L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i5-1240P has more threads than cores. Each physical core is split into multiple threads.
