Budget is the key here.
Entry level pick for me would be Intels B390 iGPU comes with the X7/X9/G3e chips in a laptop or gaming handheld, it would be about 10-20% faster than a 980Ti but comes with modern hardware for scaling and framegen puts it around an Nvida 4050 level but without VRAM limiting issues that happens on 8Gb dedicated cards these days, get 32Gb as mentioned, 24 as a minimum. Beauty of this is IGPU it will game on battery where many dGPUs in laptops do not.
A laptop 5050 should have no performance deficit to a desktop one as they both unusually have the same chip and RAM speed, most laptop chips generally offer lesser power (GPU unit config) chips with same name but not in this case, I had a 5050 in my LG gram though it was a power capped one (can’t remember if it was 45 or 65w) due to being a Thin and light and it gamed really well but you will have to manage settings more so for the VRAM limits, it can drive decent quality.
Here is B390 vs 5050 in timespy you can see graphics score level between the two 6.8k vs 8.3k, bare in mind my 5050 was power limited, a full power 5050 (non TDP capped) is probably nudging 10k I think an average 980Ti is about 5.5k on graphics score front obviously you can run this on yours and see.
But you can get some laptops with 5060 at a bargain rate if you don’t mind cheaper chunkier ones, they will only have 8Gb VRAM. Again with laptop graphics the important thing is the sustained power limits etc so you need to do research for the laptop you choose to see what it is offering, we live in a world where a well specced 5070Ti can outperform a T&L 5090, so chip name is rarely the full picture. Same for the iGPU actually, my laptop has B390 with 7500 ram and my other B390 have 8533 and 9600 RAM, higher number generally = better for an iGPU as memory bandwidth matters for graphics, though not everything, I am hardly slumming it with 7500.
In a laptop I would be looking for a 5070+ with 12/16gb VRAM personally but budget is +++ that said if you have more VRAM system RAM can drop to 16Gb if it helped bring something in budget in these RAM constrained times.
