Core i9-11900H vs Core i5-12450H comparison

Our benchmark analysis concludes that the Core i5-12450H performs better than the Core i9-11900H. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-11900H in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i9-11900H has more threads. These CPUs have different clock speeds. Indeed, the Core i9-11900H has a slightly higher clock speed compared to the Core i5-12450H. Also, the Core i9-11900H has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

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 i9-11900H has more threads than cores. Each physical core is split into multiple threads.
