Core i3-2120 vs Core i5-750 comparison

In our benchmarks, the Core i5-750 beats the Core i3-2120 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-2120 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-750 has significantly more cores than the Core i3-2120. Indeed, the Core i5-750 has 4 cores compared to 2 cores found in the Core i3-2120. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i3-2120 has a slightly higher clock speed compared to the Core i5-750. A Core i3-2120 CPU outputs less heat than a Core i5-750 CPU because of its 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.
