Core i3-5020U vs Core i5-3427U benchmarks

Our benchmark analysis concludes that the Core i5-3427U performs better than the Core i3-5020U. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-5020U in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. Our comparison shows that the Core i3-5020U has a slightly higher clock speed compared to the Core i5-3427U. A Core i3-5020U CPU outputs less heat than a Core i5-3427U CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i3-5020U has more threads than cores. Each physical core is split into multiple threads.
