Core i3-2120 vs Core i5-5257U benchmarks

According to the hardwareDB Benchmark tool, the Core i5-5257U is faster than the Core i3-2120. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-2120 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i3-2120 has a slightly higher clock speed than the Core i5-5257U. The Core i5-5257U 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.
