How long can the laptop VRAM last operating under high temperature?

[Vayra86]

Well, this laptop is advertised as a high-end gaming laptop for graphically demanding AAA games and portability is one of my priorities.

Life lesson: don't believe marketing.
Follow up class: adjust expectations.

Is 75-80 your VRAM temp after hours of heavy gaming? Some guys over at Reddit have the same problem on their high-end 4080/4090 Razor Blade and Lenovo Legion where the VRAM temp would heat up to 95-100 during GPU heavy load.

My GPU temp is mostly fine. The thing is the VRAM is always 12-16 degrees higher than my GPU core temp whether load or idle. I bought a 5-fan cooling pad but it doesn't seem to make that much difference compares to just lifting up my laptop for better airflow.

RMA doesn't seem like a great idea considering notebookcheck's review also was hitting 90+ on the GDDR6 in games. Aside from finding the courage to do a repaste for the VRAM packages, not much else to do here aside from crank up the airflow.

+10C for idle memory temp really isn't unheard of since 30 series on desktop. No point comparing core to VRAM they aren't even cooled primarily by the same part of the cooler.

I was going to buy this. mesmerized by the alien look.

but somehow I ended up DIY mini with lots of copper and liquid.

Okay, so around 3080 performance under ideal circumstances.

Aside from the repaste (who knows, maybe the stock paste application is pretty bad for the G6 and there are gains to be made), there's not much else to say.

iirc the only other example of 20Gbps GDDR6 we have right now are the two Navi31 cards, and they run scorching hot. Not sure if the G16 uses 16Gbps or 20Gbps packages for its 4080M, but if it's the latter then there doesn't seem to be any surprises (subpar VRAM cooling setup + 20Gbps G6).

4080 Mobile is between a 3080 and 3080 Ti, 4090 is close to a 3090 Ti or 4070 Ti.

My 4090 Mobile scores better than a typical 3090 Ti score in Timespy (23616 GPU score), and beats a 3090 Ti in most games, though there are occasional outliers where it loses by a few fps.

All the responses saying "Gaming laptop" is an oxymoron, or that no gaming laptops are competent are talking out their ass. These are people who have never used a high end modern gaming laptop.

I'm typing on one right now, it averages over 60 fps at 4k Ultra in basically every modern AAA title, over 100 fps in many. The GPU essentially never exceeds 70 C, in most games it doesn't exceed 65 C. The CPU doesn't get particularly hot either due to having a 4K display (so lower framerates than if I were gaming at a resolution like 1080P, which reduces the demand on the CPU) and a quad-fan setup.

My laptop has a i9-13980HX, 64 GB DDR5 @ 4800 Mhz, and a RTX 4090 Mobile.

And it weighs?

 

[Fizban]

And it weighs?

Around 7.5 pounds, I never said it was a thin & light.

It's a MSI GT77HX Titan.

Obviously still way more thermally constrained than a desktop, but the insides look like this, and it's quite well cooled.

That's a much older version of my laptop. High end, but doesn't look modern.

The 13980HX can actually score a lot higher than that cpu-monkey page suggests as well, this is a cinebench result I've personally gotten on my laptop:

In terms of silicon it's a 13900K, but performance doesn't quite lineup due to thermal constraints and reduced power draw, but not that far off, cpu-monkey shows a 13900K scoring 39652, so I got 91.58% of the desktop cpu's performance.

But the OP did specify portability as a big thing. This topic isnt about your lappy which is really just a small desktop with a battery. Good luck gaming on the go with that, for all of the 30 minutes you have without a wall socket.

Thin gaming laptops review very well. You can cry about how you're getting 200 FPS not 250 FPS, or about how your system is 30-40 dBA instead of 20-30, but most people don't care, and go back to enjoying gaming wherever they are.

As for battery life,

 

[Fizban]

Battery life really isn't all that bad. 6-8 hours of light usage. I wouldn't bother trying to play a AAA game on battery though.

 

[Bill_Bright]

Laptops can serve as desktop replacements just fine if your needs and expectations fit.

Yes, but that is a "IF".

I don't disagree, and congrats on the capable laptop, but OP specifically choose the G16 for a balance of top end performance and "portability". You have the benefit of significantly more fan and heatpipe and cooler mass. The reviews for his laptop corroborate his temps.

@EsliteMoby

I haven't tried vacuum coolers, but here's a review:

Another thing you can do is to use a thermal pad to connect hotspots inside your lappy to the chassis. using your laptop body as heatsink.

 

[sLowEnd]

Yes, but that is a "IF".

Right. It is an "if", and for many people that "if" is well within the capabilities of what the laptop form factor can deliver.

I saw an in-depth review on those vacuum air suckers and seems like they are mostly useless junks for modern gaming laptops with newer ventilation designs.

Anyway, I made a bit of a process. Did a stable -140mv core and -100mv cache UV on the CPU and a 2400mhz/875mv curve on the GPU my VRAM temp now won't exceed 90 and I'm still able to get a 18908 GPU score from Time Spy while running on MShybrid mode and performance profile with fan noise much quieter than turbo profile.

4080 Mobile is between a 3080 and 3080 Ti, 4090 is close to a 3090 Ti or 4070 Ti.

My 4090 Mobile scores better than a typical 3090 Ti score in Timespy (23616 GPU score), and beats a 3090 Ti in most games, though there are occasional outliers where it loses by a few fps.

I agree 4080/4090 mobile this gen is pretty amazing compares to the disappointing 3080 Ti last gen, and that's a pretty good score and GPU temp your getting. How's your VRAM temp?

 

[Bill_Bright]

Right. It is an "if", and for many people that "if" is well within the capabilities of what the laptop form factor can deliver.

My point was, it is a BIG "if" based, as you correctly noted, on the expectations and needs of the individual user. Heck, a $65 Dell Chromebook might meet the needs and expectations of some users. Does that justify the claim by some here that laptops are good gaming and desktop replacement computers?

If that $65 Chromebook does meet that user's needs, then IMO, that is great! It really is! And I am sure that user can play solitaire and gen up a small spreadsheet. Does that mean it IS a gaming laptop or desktop replacement?

I doubt the majority of gamers would say it is.

Your point and language changes depending on whether or not someone informed corrects it.

I think we get it, you don't like gaming laptops. That's fine, but it's an opinion, not a "fact of physics" or whatever you claimed.

Laptop GPUs are everywhere in the steam charts, so your perspective on whatever "the majority" of gamers think, seems to be somewhat disconnected from reality. Laptop workstations are also a lot more common than DIY towers, judging from the needs and buying habits of university students and the professionals I know who use software like AutoCAD. Some have both.

 

[Bill_Bright]

Your point and language changes depending on whether or not someone informed corrects it.

My point has remained mostly consistent throughout. Where I went astray, I admitted it, clarified, and even apologized for it.

My language naturally changes in response to who I am responding to. That tends to be how all humans act when conversing with different people who express different views.

I think we get it, you don't like gaming laptops.

Sadly, it is clear you don't get it. Not once, anywhere, did I say I "don't like" gaming laptops.

What I don't like is (1) folks who misrepresent what I do say and, most importantly in reference to this thread, (2) marketing weenies who misrepresent a product with exaggerated (if not totally misleading) marketing "hype".

Sure, many users are happy with their gaming laptops. And that is great! But there are plenty of examples on this site of users complaining that their "gaming laptop" keeps throttling back in performance when they play their demanding games. With a few exceptions (of course - there are always exceptions), throttling is not nearly the problem with well designed PCs designed for gaming.

Look at all the threads where users have to under-volt or add a cooling pad just to stay cool enough to play their favorites games. If a gaming laptop is being marketed as a gaming laptop, it should be able to do so with the default settings, and with out throttling.

Do you own a modern gaming laptop?

You can say this about any PC system, laptops are no different.

 

[Bill_Bright]

No - I'm just a formally trained and certified electronics technician with a computer repair business and a very long time forum helper with, "Heat is the bane of all electronics!" in my sig for a very good reason.

And yes, it is all about the Laws of Physics.

I note once again,

no less than 4 other posters in this thread commented before me that laptops and gaming are not meant for each other.

Cleary, you are right and everyone else is wrong so I see no point in discussing this further. It is not helping the OP.

What do you mean by desktop replacement though? Cause judging by your signature, a cheap ass laptop outperforms your desktop PC.

Obviously the more you want the performance of a laptop to match a desktop, the more you have to sacrifice in terms of mobility. But you can get the performance of a mid range desktop on a small lightweight laptop nowadays so don't see any issue with it.

You can get the performance of a last gen halo tier desktop (3090 Ti) with a current gen laptop that is 2cm thick.

That's about 4070 Ti level in current gen.

So far, those who've commented who actually own a modern gaming laptop seem pretty pleased with them.

I'm enoying more playing on my g14 than my 12900k + 4090 desktop, so there is that

Laptops can serve as desktop replacements just fine if your needs and expectations fit.

The laptop I used during my undergrad wasn't a blazing fast thing by any stretch of the imagination (i5 4200M, GTX 765m), but I adjusted the scope of my gaming to fit. (Was playing mostly Overwatch, FFXIV, and WoT at the time on med-low.) I had no issue doing assignments on it. Matlab, R, Excel...etc. ran without fuss.

I am back on a desktop now, of course, but that's because I don't need the portability of the laptop anymore and I enjoy the building process and customizability aspect of it. I'm not going to pretend that the laptop wasn't able to do what it needed to do though.

To answer OP question those temps are within spec, VRAM runs hot on desktop GPUs also.

For what its worth, i have actually been gaming on my laptop lately more often than my main PC in my system specs and it handles it flawlessly.. the 4080M helps though, its also docked with external display, keyboard, monitors, etc.

Nice to have the portability when needed with it.

4080 Mobile is between a 3080 and 3080 Ti, 4090 is close to a 3090 Ti or 4070 Ti.

Το be fair I consider them huge, I use it a lot on my couch and going above 14" is too much for me. So im kinda stuck at whatever hardware something like a g14 can offer. Although looking at your link, this years g14 comes with a 4090, lol. Going to check a review and see how well it performs.

With that said im ultra happy with my 2022 g14, and the nice thing about laptops is that - because of how small the screen is, you don't need to play every game at native 1440p or 4k resolutions. You can drop down a notch and still have insanely high ppi. Which is not the case with my desktop.

Hey uh op is still here asking questions… maybe stop detailing their thread to argue about your preferences
