This processor has never bogged down. Running it on a Dell Latitude 5591 and powering 2 additional monitors. During pandemic runs like a champ, compiling code and tons of huge spreadsheets open.

loud, but performance as hell for a notebook cpu

This is a okay H series mobile CPU. 4C 8T CPU with base clock of 2.5Ghzm turbo up to 4.2Ghz. TDP of 45W, maximum down to 35W with 2.0Ghz. Should perform very well when doing daily task. Could handle most of the game with ultra setting, but will going to need a good GPU for that.
