Intel Core i5-8400 vs Intel Core i5-12450H

Core i5-8400 vs Core i5-12450H comparison

In our benchmarks, the Core i5-12450H beats the Core i5-8400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-12450H has slightly more cores with 8 cores compared to the Core i5-8400 that has 6 cores. It also has more threads than the Core i5-8400. Our comparison shows that the Core i5-8400 has a slightly higher clock speed compared to the Core i5-12450H. Despite this, the Core i5-12450H has a slightly higher turbo speed. The Core i5-12450H outputs less heat than Core i5-8400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i5-12450H has slightly more L2 cache when compared to the Core i5-8400. The Core i5-12450H also has slightly more 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. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
