Intel Core i3-7020U vs Intel Core i7-4558U

Core i3-7020U vs Core i7-4558U comparison

In our benchmarks, the Core i7-4558U beats the Core i3-7020U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-7020U in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i7-4558U has a slightly higher clock speed compared to the Core i3-7020U. A Core i3-7020U CPU outputs less heat than a Core i7-4558U 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 i3-7020U has more threads than cores. Each physical core is split into multiple threads.
