Decent performing CPU considering it's age, general computing tasks tend to run smoothly. CPU intensive games tend to suffer slightly, but overall a great foundation for a budget system. Would not recommend for newer builds however unless found at a low price as there are many more cost effective choices available.—Dec '20

good cpu, 2.7 ghz is fast enough. if only it used a uhd graphics chip but that's fine, going from a 4200u 1.6ghz. so this is good
