Intel Core i5-12450H vs Intel Core i7-1355U

Core i5-12450H vs Core i7-1355U benchmarks

According to the hardwareDB Benchmark tool, the Core i5-12450H 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.

In terms of the number of cores of each of these CPUs, the Core i7-1355U has slightly more cores than the Core i5-12450H. Indeed, the Core i7-1355U has 10 cores compared to 8 cores found in the Core i5-12450H. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-12450H 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 i7-1355U has significantly more L2 cache when compared to the Core i5-12450H. 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 i5-12450H has more threads than cores. Each physical core is split into multiple threads.
