NVIDIA GeForce RTX 4090 Laptop GPU Pulls up to 200W, GA103-based, Lineup Power Detailed

[btarunr]

At its 2023 International CES event, NVIDIA is expected to launch not just its desktop GeForce RTX 4070 and RTX 4070 Ti graphics cards, but more importantly, also its GeForce RTX 40-series Laptop GPU series powering next-generation gaming notebooks based on the upcoming 13th Gen Core "Raptor Lake" processors. NVIDIA seems to be making a very tight rope-walk between power-management and generational performance increase in this power- and thermal-constrained form-factor. Wccftech scored a major scoop on the specs of various RTX 40-series Laptop GPUs.

The GeForce RTX 40-series "Ada" Laptop GPU lineup will be led by the RTX 4090 Laptop GPU, based on the 4 nm "AD103" silicon (same one that powers the desktop RTX 4080). It will be equipped with 16 GB of memory, a yet-unknown core-configuration, GPU Boost frequencies of up to 2.04 GHz, and typical power draw ranging between 150 W to 175 W, which can peak up to 200 W thanks to the 25 W dynamic boost range (power permissible by the platform if the other components such as CPU aren't drawing their peak power).



Moving down the lineup, we see the RTX 4080 Laptop GPU being based on the "AD104," the same silicon that powers the upcoming desktop RTX 4070 Ti and RTX 4070. The core-configurations remain unknown, but given the naming, the RTX 4080 Laptop GPU likely maxes it out. The SKU features 12 GB of memory across the chip's 192-bit memory bus, boosts up to 2.28 GHz, and has a similar power-limit to the RTX 4090 Laptop GPU—150 W to 175 W typical graphics power, with additional room for 25 W.

The RTX 4070 Laptop GPU is based on the yet-unreleased 4 nm "AD106" silicon which, unless we're mistaken, features a 128-bit GDDR6X memory interface, giving this SKU its 8 GB of memory. This GPU gets typical graphics power in the range of 115 W to 140 W, with room for 25 W more. Moving lower down the stack, we have the RTX 4060 Laptop GPU, and the RTX 4050 Laptop GPU, both of which are based on the 4 nm "AD107" silicon, which is probably the smallest "Ada" implementation. The former gets 8 GB of memory, and the latter 6 GB of it.

I can only imagine the efficiency of AD103 in a laptop being fed 175-200W, that would be insane for a portable powerhouse.

Naturally the price will be sky high, but I can't see that top chip being challenged for the mobile crown unless Navi 32/33 are considerably more efficient than Navi 31, should be an interesting generation for <200w parts both mobile and desktop.

Finally they went back to 200w, unfortunately the naming scheme is as bad as with Ampere.

 

[Chaitanya]

So coupled with 150W CPUs, these laptops are going to need a large power adapter coupled with beefy cooling systems(so only suited for 17" and larger laptops).

Yup. Should be as fast as a desktop 3080 at minimum and nipping on the heels of a desktop 3090.

I can't imagine this being fun.

I played with a Gigabyte A5 K1 recently, Ryzen 5600H, a 100W+ 3060, 180W power brick. At full draw it was tested as 58 dB, one of the loudest laptops - and it really does sound as a hairdryer, and performas as one - small slots expelling 180W of heat, one of them aimed directly at your right hand... I can't Imagine another 150W (hungrier GPU + CPU) in a laptop body.

Enjoy your 20 minutes of autonomy.

 

[TheinsanegamerN]

And even the 4050 is an 85 watt part.

That does not bode well at all for those of us with low profile desktops that we will ever get a proper replacement for the 1650

 

[Bwaze]

All these high power gaming laptops jump to energy saving when unplugged. So they do last longer - although they usually have small batteries, so they can have bigger coolers.

But then you're carying around a bunch of performance you're not using. And 200+W power bricks also weigh as much as a low power laptop.

 

[fancucker]

200W is the upper limit of power consumption (in limited scenarios), it's going to pull much less. The same fuss was made over the desktop counterparts and their power draw during gaming proved to be much better than the competition.

 

[Bwaze]

But card like this will be paired with 1440p 144Hz+ laptop monitor, if not 4K. Sure you can limit what the card will pull by giving it an easier job... Run Portal, and it will hardly warm. Run Portal RTX, and you'll have full power draw, although you'll use DLSS and see only low FPS...

Just as desktop 4090 takes 450w while day-to-day gaming, the leptop version will take 200w.
That is, next to never.
We all know it, but it's still fun to make jokes about high NV power consumption

 

[ExcuseMeWtf]

That's DTR territory, not much of a portable anymore.

 

[ARF]

Meh, I prefer AMD Radeon.

No, this is simply a 200W card with a much lower peak performance. This is not a 4090. Its not even built on a 102 SKU (so its not wider than it needs to be, to consume less for same perf).

Nobody is even remotely considering an overclock here... and this mobile gpu won't be CPU limited either.

These are portable computers, not laptops.

And there are many people who need this kind of compute power on the go. And those people don't care one bit about running on a battery. There are outlets everywhere.

 

[Sake]

The usual pro-Nvidia comments are coming faster than ever . But it's actually ridiculous that anyone thinks this is an efficient video card.

As long as business is going well, and the pay is coming, nothing else matters.

AD103?

200W in mobile? Jayzuz!

Everywhere...

And we all thank you for your service, coming to this news article, just to say this.

AMD'S volunteer marketing department seem to be really happy doing this for free.

Good for bending plastics, acrylic or scorching wood.

 

[TumbleGeorge]

I think that after exceeding a certain weight and consumption, it is mandatory to exclude products with exceeding parameters from the class of mobile devices, also mobile components. Otherwise, I, as a person of average physical abilities, can carry the 25 kg desktop computer in my hand by installing a handle on the case lid. Can I convert class of my PC from desktop to mobile(laptop) based on this option?

 

[TheDeeGee]

4090, but the performance of a 4060.

 

[trparky]

I thought that they can't call them laptops anymore ever since someone had their crown jewels baked.

 

[ThomasK]

I wonder why neither nvidia or amd still can't avoid deceivingly naming their mobile GPU's according to their correct desktop counterparts.
