I have a Lenovo Ideapad 330-15ARR with Ryzen 5 2500U and Radeon 540 dGPU. I'm a bit confused as the dGPU performs poorly on some old games even though I installed official Lenovo drivers. CS:GO runs from 40-60 fps at max settings with V-Sync off which is a bit questionable since this is a really lightweight title and the dGPU should be able to life Source Engine without a problem. Looking at its spec sheet, it seems like the equivalent card would be the RX variant RX 540 which has a higher memory bandwith and texture compute units unlike the base 540 only. There are no reviews and comparisons for this specific GPU online so it's a bit confusing to see what this was really made for.
