Discussion Ada/'Lovelace'? Next gen Nvidia gaming architecture speculation

Looks like the Twitter leakers will have eggs on their faces.

The specs look right in line with the leaks.

Looks like nvidia has been testing PSUs at 12volts 55 amps:

Spoiler: GN youtube link

and recording connector failure / melting.

With the recent ones, sure. The performance doesn't. >2-2.5x GA102/Navi21 performance seems like a delusion right now.

There is no freaking way NV doesn't do a massive price drop when the Ampere inventory sells out or does the mid gen refresh "Ti model 1 tier down is within 5% performance of the non-ti model 1 tier up" shenanigans.

 

[DisEnchantment]

- AD102, ~600mm2 = $1599 ---> $2.67 $/mm2

Very unlikely to fit 76B in ~600mm2 which is 126 MTr/mm2 (iPhone SoC is 132 MTr/mm2) , Clocks will get nerfed. Hopper is only 98 MTr/mm2.

So wait, after all this time we have a 4080 12GB at $899 MSRP that just ties the 3090 Ti with DLSS3.0 off? Am I reading that correctly?
The same 3090 Ti that's only like 10% faster at 4k than a 12GB 3080 Ti, a card currently selling for under $750?

Woof.

LOL glad I didn't watch this garbage. What a joke, I hope Nvidia has to eat all those 30 series chips those vultures still have in stock.

Yes, but NVidia is actually claiming up to 4X performance in the video. So the leakers are basically confirming what the video says.

Yes, that claim is misleading, but I wouldn't blame the leakers for that. They had both the specs and NVidia's outlandish performance claims correct.

Hell, the most unimpressive launch in decades.

He just launched RTX4000 showcasing Portal (2007) ???? really ???

 

[moonbogg]

They are clearly only interested in selling 4090s and forcing everyone else to buy 3000 series cards. Used market is the only reasonable choice now.

God I hope AMD has something good coming. New generations are supposed to increase performance per dollar lol.

Im willing to bet from now , that they will match price the NVIDIA ADA and we will see the lower end SKUs only by next summer .

Ampere production on Samsung 8nm is continuing. They aren't going top "sell out" of Ampere anytime soon. Total guess but I see Ampere production continuing well into 2023 and likely until 4N is the new "value" node which would be 2024 when 3nm is beginning to start production on PC parts.

Woof.

nvidia priced 40 series to sell 30 series. MSRP wise 4090 is the only one that brings real meaningful increase in performance/$ metric. All other cards have very little to no increase in performance/$ metric. As expected from an arrogant monopolistic company that has a glut of 30 series to sell.

Your logic makes sense. We'll just have to wait until we get a teardown to confirm. Speaking of die shot, I didn't see what should be an obvious 96 MB of L2 cache on the die shot that was provided by Nvidia. I know it's a render, but even the render didn't show an obvious bank of cache.

 

[Borealis7]

the GTC presentation is VERY impressive. say what you will about nVidia - expensive, power hungry, greedy, whatever - the technology and the tools they have developed are AMAZING. this goes far beyond gaming. nVidia is operating in the upper atmosphere of AI and simulations while AMD is still benching Forza Horizon. i'm really wondering if these cards are aimed at gamers at all.

 

[Saylick]

Is it just me or are there no IPC gains for Lovelace?

Full AD103 = Full GA102 = 84 SM = 10752 shaders
4080 16 GB = 76 SM = 9728 shaders
Ratio = ~0.91

Rated boost clocks for 4080 16GB = 2.5 GHz (actual clocks likely higher)
Rated boost clocks for 3090 Ti = ~1.86 GHz (actual clocks are higher at ~2 GHz)
Ratio = ~1.34

Final ratio, excluding the reduction in memory bandwidth due to a smaller 256-bit bus = 1.22x

I feel strange having to ask this question, but what are GPUs used for these days? Why would someone buy a 4090 or 4080? For gaming? Gaming how? Because they want ray tracing in 4K with high FPS? How many people can be bothered to care about chasing that crap? Honestly.

 

[CP5670]

This is not that impressive compared to all the "leaks." Only the 4090 is a real step forward from current cards. It's cheaper than I was expecting though. I might get one but am not sure about the power and heat output.

Filling out PC cases with cool looking parts obviously

Exactly. For ANYONE playing competitive online games, you don't go higher than 1080p + 240hz. I suppose dudes playing single-player games want to sit there and stare at 4k with maximum effects but yes - we are at the point of diminishing returns. You can scoop up a vanilla 3080 and be set for competitive games, where frame rates actually matter, for the next 4 years.

 

[n0x1ous]

I see they finally removed the symbolic Nvlink connector even on 4090. @AdamK47 thats a real kick in the pants.....well no, not really. Its been dead for years. You grabbing one day one with me?

Machine learning stuff, broadly, I think. Hence them building some of these chips up so big/expensive. Perhaps AR/VR at some future point?

You can definitely see why they started focusing into RT. Without it, even at 4K, there just wouldn't be a remotely sane reason to have the top end cards. With it its just about possible to believe things if you've got the money & don't care about the power draw.

Yes very much. Outside of niche needs like high resolution VR headsets and flight sims, the whole thing is feeling pretty deflated.

ZOTAC unveils GeForce RTX 4090/4080 AMP & Trinity graphics cards - VideoCardz.com

ZOTAC GAMING ANNOUNCES THE GEFORCE RTX 40 SERIES POWERED BY THE NEXT GENERATION GPU ARCHITECTURE HONG KONG – September 21, 2022 – ZOTAC Technology Limited, a global manufacturer of innovation, ushers in a new era of PC gaming with the unveiling of our next-generation ZOTAC GAMING graphics card...

videocardz.com

Of the AIB PRs that Videocardz has, this is the only one I saw that mentions pricing. Even then... Zotac has 3 different cards each, one of which says it's the MSRP and the others are presumably more than that.
