Core i7-8700 vs Core i5-12450HX comparison

Our benchmark analysis concludes that the Core i5-12450HX performs better than the Core i7-8700. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8700 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-12450HX has slightly more cores than the Core i7-8700. Indeed, the Core i5-12450HX has 8 cores compared to 6 cores found in the Core i7-8700. But they both have the same number of threads. Our comparison shows that the Core i7-8700 has a slightly higher clock speed compared to the Core i5-12450HX. Also, the Core i7-8700 has a slightly higher turbo speed. The Core i5-12450HX outputs less heat than Core i7-8700 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core i5-12450HX has more L2 cache than the Core i7-8700. However, both these chips have the same amount of L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-8700 has more threads than cores. Each physical core is split into multiple threads.
