Intel Core i5-9500 vs Intel Core i7-1255U

Core i5-9500 vs Core i7-1255U comparison

In our benchmarks, the Core i7-1255U beats the Core i5-9500 in overall performance. Despite this, the Core i5-9500 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i7-1255U has significantly more cores with 10 cores compared to the Core i5-9500 that has 6 cores. It also has more threads than the Core i5-9500. Our comparison shows that the Core i5-9500 has a significantly higher clock speed compared to the Core i7-1255U. Despite this, the Core i7-1255U has a slightly higher turbo speed. The Core i7-1255U outputs less heat than Core i5-9500 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i7-1255U has significantly more L2 cache than the Core i5-9500. The Core i7-1255U also has slightly more 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. For instance, the Core i5-9500 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
