I'm looking at getting the Dell gaming laptop with a Ryzen 7 5800H and rtx 3060. What kind of fps can I expect? Can it run 4k @ 120Hz? It has a HDMI 2.1 output that can output to my 4k HDMI 2.1 TV. Thank you.
https://www.cpubenchmark.net/singleThread.html You should be more than fine according to these benchmarks for single thread CPU, maybe not at 4k though.
His CPU is not on the list for some reason, but should be enough, yes: https://www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+7+5800H&id=3907
It is on the list but you have to select laptops from the menu for them to appear. Single core is over 3000, similar to the latests 11th Gen i7 high performance models, which are real flying machines apparently.
