Intel Core i9-9900 vs Intel Core i5-12450H

Core i9-9900 vs Core i5-12450H comparison

According to the hardwareDB Benchmark tool, the Core i5-12450H is faster than the Core i9-9900. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i9-9900 has more threads. Our comparison shows that the Core i9-9900 has a significantly higher clock speed compared to the Core i5-12450H. Also, the Core i9-9900 has a slightly higher turbo speed. The Core i5-12450H outputs less heat than Core i9-9900 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, both these CPUs have the same amount of L2 cache. The Core i9-9900 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. Indeed, the Core i9-9900 has more threads than cores. Each physical core is split into multiple threads.
