Core i3-8145U vs Core i5-5300U comparison

According to the hardwareDB Benchmark tool, the Core i3-8145U is faster than the Core i5-5300U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-5300U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-5300U has a slightly higher clock speed compared to the Core i3-8145U. Despite this, the Core i3-8145U 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. The data shows that both these CPUs have same sized L2 caches. The Core i3-8145U also has slightly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i3-8145U has more threads than cores. Each physical core is split into multiple threads.
