You havent bought it yet ? Prices are climbing steadily .

I'd like to know myself. I heard it's pretty good and can maintain around 60 fps on Cyberpunk 2077 RT overdrive and can use like 15gb vram usage at 2k, but it is still an inferior version.

is it bad? well no.
but it's ALOT slower on average then the desktop version, as usual.

this also heavily depends on what laptop you get. as they will all have different wattage allocation to the graphics chip. will also depend on how well this laptop cools said gpu.

will it be fine for minecraft with your mods and textures. i'm going to say yes. as even a low wattage 5080 mobile chip is still a decent chip.

I don't own it but it will be great at 1440P gaming when plugged in, it's a flagship mobile chip.

Cooling to run it's max TDP is usually the biggest issue.

5080 mobile is weaker than a desktop 5070
but better than 5060ti

but also depends on the laptop its in
if the laptop has good cooling and better power delivery to the mobile gpu, it will perform better

mobile 5080 is 80-150w
nowhere near the 360w of the desktop version

In regards to loading modded Minecraft with shaders: what settings would be recommended for maintaining stable FPS?

This question is like asking "how long is a piece of string" and the answer is "it can vary" because there's so many variables that come into play here. Notable ones would be on your desired frame rate target, your render distance, your other in game settings (simulation distance, entity distance, etc.), your mods, your shaders, your shader settings, and (if using shaders) your resolution.

The way the game is designed and operates does not perform well with real time lighting. Adding it drastically (and I can not emphasize that word enough) reduces performance. Expect a fraction of the performance you would get without shaders. This is more true with recent versions (1.21.5+).

To get playable performance at a not-tiny render distance with shaders, you typically need mods like Distant Horizons or Voxy. These are mods that allow you to keep your "real" render distance tiny, but they generate LODs to display (instead of chunks) at a distance. While these result in more performance, they come at a quality cost (configurable) as well as a one time up front CPU performance (cost depends on LOD quality). By default, Minecraft doesn't use LODs like other games because its world is something that isn't generated until runtime (meaning there is no existing world to use for creating them). Therefore, these LODs need created in real-time and have an added CPU cost.

In general, if you are serious about heavily modded Minecraft with shaders, a laptop wouldn't be my first recommendation. The thermal/power constraints of laptops tend to become more relevant than usual, and like the above post mentions, the limits can vary model to model and it can be hard to find out what they are. If you need a portable solution though, then the RTX 5080 mobile is one of the most performant options as far as that goes, so...

According to techpowerups charts it's around a 4060 ti 8gb or a 5060 8gb. No idea if that is accurate at all. 80w power draw. Gpu also has 16gb vram. It's not comparable to the desktop 5080 just treat it like a seperate card.

That's at half performance, here is a vid of a laptop where the 5080 runs at 170W and it's pretty good, just need a thicker laptop with good cooling not a thin and light.
