Intel Core i3-2120 vs Intel Core i5-5300U

Core i3-2120 vs Core i5-5300U benchmarks

Our benchmark analysis concludes that the Core i3-2120 performs better than the Core i5-5300U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-5300U 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 i3-2120 has a significantly higher clock speed compared to the Core i5-5300U. The Core i5-5300U outputs less heat than Core i3-2120 thanks to a significantly lower TDP. 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 i3-2120 has more threads than cores. Each physical core is split into multiple threads.
