[AEgem]

Hello, I have HP 250 G3 K7J62ES Notebook which has 4210U (4th generation), and I have a Lenovo Thinkpad T420 i5 which has 2520M (2nd generation). Lenovo's features is better than HP but Lenovo's proccesor is a 2nd generaiton i5 (features better) and HP 's proccesor is a 4th generation i5. Which one I should use? Which one has more performance? There are links of laptops. ((Sorry HP's site language is Turkish.)) Thank you for your responses...

If Windows 10 is your goal, use the i5-4210U. You will have far better support, especially with graphics. With the i5-2520M and Windows 10, you only have the Microsoft generic graphics driver.

Thank you for your answer. My goal is performance. So, which one I should use?

While it's going to be close, considering the Turbo feature, the i5-4210U should come out on top of the i5-2520M -- and consume half the power in the process.
