Intel Core i5-13420H vs Intel Core i5-1245U

Core i5-13420H vs Core i5-1245U benchmarks

Our benchmark analysis concludes that the Core i5-13420H performs better than the Core i5-1245U. Despite this, the Core i5-1245U has the advantage in our gaming benchmark.

With info from our database, we find that the Core i5-1245U has slightly more cores with 10 cores whereas the Core i5-13420H has 8 cores. But they both have the same number of threads. Our comparison shows that the Core i5-13420H has a slightly higher clock speed compared to the Core i5-1245U. The cache sizes of these CPUs are different. Indeed, the Core i5-13420H has slightly more L2 cache than the Core i5-1245U. 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 i5-13420H has more threads than cores. Each physical core is split into multiple threads.
