Core i5-1235U vs Core i5-12450HX comparison

According to the hardwareDB Benchmark tool, the Core i5-12450HX is faster than the Core i5-1235U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-1235U in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-1235U has slightly more cores than the Core i5-12450HX. Indeed, the Core i5-1235U has 10 cores compared to 8 cores found in the Core i5-12450HX. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-12450HX has a significantly higher clock speed compared to the Core i5-1235U. Furthermore, both these CPUs have identical turbo speeds. A Core i5-1235U CPU outputs less heat than a Core i5-12450HX CPU because of its significantly 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 i5-1235U. 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 i5-1235U has more threads than cores. Each physical core is split into multiple threads.
