so basically 2080 rtx is not good enough in a laptop anymore?
A very technical question this. Something to keep in mind when looking at a Laptop with a renderer (GPU).
Even though it has the same model number it is the "Mobile" Version. GPU's comes in different forms. You will get like a RTX 2080, a RTX 2080 (LP) and a RTX 2080 (M). Each one of them are different but has similar components.
LP is low profile and is weaker than it's "full" counterpart because it has about half the components the "Full" one has to be able to make it smaller. The Mobile is designed to be compact, energy efficient as well as thermal efficient so they are again weaker than the LP's.
Do not get me wrong, they are all RTX 2080 but when bench marking, they will have different results to what they were designed for but will be equal to another GPU when testing and not to the "Full" card.
When the game does it's checks on the system, it will detect the name but will adjust to the design. Worst case scenario you will have less FPS. SO not bad if you are not that much into the immersive experience.
Ony problem you might experience (I might be wrong here) will be bottlenecking. Data moving from CPU to GPU and back at such a speed that it loses track and it start slowing down to catch up. You usually see this when you get a sudden stutter or lag in a game. There are ways to get past it by tweaking some settings.
If it must be a laptop for mobility, then it should be fine. Check that you have an SSD in there (will give you 6GB/s transfer rate) and up the system cache to alleviate so of the data from the RAM. But overall, you should be fine. Unfortunately playing solitaire on a laptop also makes it a Gaming Laptop (Because that is what I use it for) so calling something a Gaming laptop does not necessarily mean it is.
Just saw your msg about the 3080. Great but again remember it is Mobile version.
Spec's
That is what I found on the Laptop. Obviously, you are already busy doing your homework on it which is the best way before buying. You will never (NEVER) find the perfect PC or Laptop. There will be pro's and Con's on all of them.
