RTX 3080 Mobile is… Complicated

Nvidia's new RTX 3080 mobile GPU is the fastest you can get in a laptop, but Nvidia's marketing team hasn't made it easy for consumers to tell how fast each laptop will actually be.

Normally i'm not all about calling out stupid titles or thumbnails, but what even is this thumbnail? At least put a laptop in there or something, jeez.

At 2:29, the aircraft shown is N694PB, which is a TBM 700 (https://flightaware.com/resources/registration/N694PB). I know it doesn't matter .

 

One thing that might be a bit more important though is that I'm pretty sure the laptop RTX 3080 uses the GA104 die. Nvidia should have called in an RTX 3070 Ti mobile or something like that imo.

 

Also, at 8:41, the graph is labeled as 4K, but I think the actual performance is from 1080p.

 

Overall though, I'm actually kind of impressed with these GPUs, the naming just doesn't make sense.

that thumbnail looks like Linus is on the toilet

now I dont even have to watch the video

Most Accurate Title 2021 being awarded early this year

There is an error in the video, 3080 mobile uses a fully enabled GA104 die, not GA102 like the desktop 3080.

again linus with something i can't even dream to buy come on linus and nvidia  something affordable please

The Thumbnail is no longer tech, just Linus.

You could also say that it's basically a rip-off, at least on some devices it will be. And IIRC the video also has something else wrong besides the GA102/104 confusion (if that is actually the case). They call it "3080/3070 Max-Q". Nvidia willingly dropped the "Max-Q" moniker, so they are called just RTX 3070/3080, but not "**** Max-Q" anymore. That's what is so bothersome, because on a regular non-Max-Q GPU, you knew what about to expect, even though the TGP variation was a thing after all. But now you have from the lowest Max-Q to the highest "Max-P" settings and it isn't even differentiated by the name. So you're practically buying the cat in a bag. It can range from slightly below desktop GTX 3080 performance (in ultra-fat laptops) to sub-3070 Mobile performance on a 3080.

max q branding still exist, just now the tdp in max q is flexable, this info is in the wan show

Is that constipated Linus in the thumbnail? LOL

 

Laptop manufacturers are rolling the dice if they think they can make a power trade-off between CPU and GPU. There are plenty of non-gaming workloads where GPU and CPU get maxxed out. The Dell XPS already suffers from this scenario eating into battery reserves when it's wimpy AC adapter cannot keep up.

 

Yeah, you could blame TB/USB-C spec for that, except nobody told Dell not to put a regular barrel connector on the damn thing for power like 99.99% of every other laptops do. The finger pointing goes to Dell. This is not the fault of bad design, rather senseless penny pinching.

 

A properly designed laptop power solution should be able to handle BOTH a CPU power draw and GPU running at 100%. In fact, with the display at full brightness, external peripherals drawing power and a mechanical drive inside there's really very little actual power being saved by downsizing that AC adapter. The fact that modern silicon is power efficient should equal to longer battery times - that's where the advantage needs to be shown. But attempting to restrict where the power goes is nothing but an unnecessary risk that the user should not be forced to choose.

 

There were days where a 300W power brick was NECESSARY because you had desktop CPU's and multiple graphics cards. Those days are gone. For a modern laptop with today's mobile spec processors and graphics there is just no argument to downsize on power, unless they have downsized on cooling, but that's another completely different can of worms.

Nice job matching the lipstick to the hat, Linus.

At 8:17 in the video, was that "deeper dive with numerous rtx 30 series laptops" ever published?
