Core i3-8145U vs Core i5-5257U comparison

Our benchmark analysis concludes that the Core i5-5257U performs better than the Core i3-8145U. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-8145U in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Core i5-5257U has a slightly higher clock speed than the Core i3-8145U. Despite this, the Core i3-8145U has a slightly higher turbo speed. A Core i3-8145U CPU outputs less heat than a Core i5-5257U CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches. The Core i3-8145U 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. Indeed, the Core i3-8145U has more threads than cores. Each physical core is split into multiple threads.
