Intel Core i3-8145U vs Intel Core i5-7300U

Core i3-8145U vs Core i5-7300U specs and performance

Our benchmark analysis concludes that the Core i3-8145U performs better than the Core i5-7300U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-7300U in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-7300U 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.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i3-8145U has more threads than cores. Each physical core is split into multiple threads.
