Been out of the loop for about a year on GPU's and hardware so just wanted to get a bit of advise. Been traveling in my camper so had a Lenovo legion 5 laptop with NVIDIA 3070 and AMD Ryzen 7 5800H to play Warzone ;) . I've now moved into a house and using my laptop with a 1440p 144hz 27" screen and it runs great. To be honest there is no reason to change it but I fancy a desktop set again and just looking at option's. What would be a good jump up in performance from my current card, budget would be around the £500 mark and this is for second hand card.
 
Not sure the RX7800XT will be a huge leap over the 3070. You're probably looking at the RX7900XT at around £800 to see a noticeable improvement.
 
Checking the spec its a 3070 115w GPU so slightly slower than the Desktop version but interestingly I've read you can overclock it in the bios.
 
Depends a lot on the laptop variant - 115 watt is more circa desktop 3060 performance while the 130-140 watt variants aren't far behind a 3060ti. So most desktop GPUs in the £500 range will be a fair bit faster but probably not dramatic so.

A decent 7800XT will obliterate it! lol

Thanks I do a bit of research.

From a quick look it didn't look like a massive jump.

This seems to be the best value at the £500 mark

£500 is a nice price :)

Quite a bit slower - this is my full power 3070 mobile vs 3070 desktop in Hogwarts Legacy for instance:

99FPS for the 3070 laptop, 155FPS for the 3070 desktop.

Basically 55% difference - not entirely fair as the laptop has a little bit of a CPU disadvantage in the game otherwise it would be a fraction closer, the 115W 3070 in comparison would be getting around 90FPS in that scene. In comparison a desktop 3060ti would come in at ~140FPS and a 7800XT at 193FPS, 4070 at 167FPS, 4080 at ~233FPS.

In other games my laptop 3070 isn't too far behind a desktop 3060ti.

I thought mine was the 130w version making it a little better?
 
Legion 5 will be the max power variant of the 3070 so 125-140w with Dynamic Boost. Performance will be broadly in line with a Desktop 3060Ti thus use that as the comparison point for Desktop comparisons.
 
With a GPU costing £500 just by itself this is going to be one very expensive upgrade unless you already have a decent desktop pc that just needs a new GPU? It just doesn't seem worthwhile when you even say yourself that there is no real reason to upgrade apart from fancying a desktop setup again. You could always plug the laptop into your monitor and use a normal keyboard and mouse.
 
I would be tempted the same as above too, GPU prices are still a bit silly, especially if you have the higher power variant of the laptop 3070. If you really want a desktop now though, can't go wrong with the 7800 XT linked previously. Or if you can wait a couple of months see how the RTX 40 series super are priced.
 
i have just moved away from that exact laptop in question to a desktop pc, just got a 7800xt for it. main reason for me was i output to 1440p and the 3070 laptop gpu was struggling with a few games, but the other thing was the noise, the laptops are great but very noisy and i found the experience not as smooth due to boost clocks changing all over the place.

This is what I do at the moment, i'll probably just stick with this set up for now as it seems more like a side grade than a up grade.

Depends a lot on the game in my experience - some games were close to the desktop 3060ti but others like Hogwarts Legacy the gap can be quite a bit bigger - although I did it at 1080p above as I've reference for how some other GPUs perform in the game at the same settings, while the gap actually closes up a little more at 1440p - though I think that is mostly due to exposing the lower laptop CPU performance less rather than difference in GPU.
