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

[Saylick]

More Twitter leaks. Allegedly not the flagship Lovelace card, this is 4K RT (no DLSS). Probably the 4090 in Nvidia picked games.


To be honest, this is kind of lackluster? The rumor mill has hinted that the raster uplift is ~2x and the RT uplift is supposed to be higher than the raster uplift, but this doesn't seem to back that claim unless Lovelace is pretty much Ampere with a larger L2 cache to make up for the same width memory bus, because then both raster and RT scales similarly with the SM count.

Also, N21 RT performance is roughly 2/3rds that of GA102, so if N31 can hit 3x the RT performance (as surmised by a couple of Twitter leakers, i.e. RT uplift is much closer to the TFLOP uplift) then we can expect N31 to be similar to the 4090 as well. This is shaping up to be a very interesting GPU generation.

Edit: Apparently, NV will show off the 4080 as well? Looks like a triple slot cooler for either the 4080 or 4090.

Yeah I'm kind of expecting the increase in raster and RT to be about the same. I still suspect there is a bandwidth problem even with the big L2. The fullish AD102 is probably 20-25% faster.

I think it's going to be two slots for RTX 4080 and three slots for RTX 4090. RTX 4080 would be wider than previously thanks to larger fan.

They could see the same sort of bottlenecks forming as AMD already has. EG During a bandwidth heavy deferred game the title has to go out to main memory to build the g-buffer, there's no cache tricks available there, so at high resolutions the lack of bandwidth to main starts choking relative performance.

Fortunately for all of us programmers are well aware of the bandwidth deficit and newer engines are concentrating on things like visibility buffers, which swap heavy bandwidth use for heavy ALU use, which is fine as there's plenty enough ALU to go around. EG UE5 has a visibility buffer setup, and a 6900xt runs almost as fast as a 3080ti at 4k in the Matrix demo, despite the 6900xt being at a deficit at 4k in older traditional deferred titles.

Wouldn't it be funny if Lovelace edges out RDNA3 is raster, but RDNA3 takes top spot in RT oomph this gen? 😅

Either way, more powerful RT capabilities across the entire spectrum of vendors (hell, even Intel's Alchemist is not too shabby in RT, relative to it's raster showing at least) is a very good thing. Moves the industry more towards a Metro Exodus: EE direction. Current console gen refresh ain't that far away either (and for the love of god I hope they focus more on 4K60 and much improved RT rather than silly 8K marketing grabs).

Interesting. AMD's "together we advance_PCs part 2" centered around RDNA3 (and probably V-Cache Zen4) will probably be announced soon as well.

I am so f'ing ready for next gen to be announced. One way or another, we'll finally be leaving this cursed generation behind (aside from hopefully a dirt cheap top end card from this gen occupying my PC).

LOL, so apparently the Twitter user QXL made up the Ada Lovelace performance chart as a honeypot for the rumor mill and the usual suspects took the bait, according to MLID:

Alleged GeForce RTX 4090 GPU runs at 3.0 GHz, scores 20K points in TimeSpy Extreme - VideoCardz.com

First leaks on NVIDIA upcoming GeForce RTX 4090 Over at Chiphell forums, mysterious screenshots were posted showing an unnamed GPU reaching 3.0 GHz clock. The graphics card scored 20192 points in 3DMark Time Spy Extreme, so just a bit more than rumored 19K for GeForce RTX 4090 GPU. The overall...

Speaking of sketchy rumors, got a claim of the 4090 doing 20k in TSE. Which is about 35% faster than a 2.9 Ghz 3090 Ti. So the scaling isn't great given the extra 50% SMs that the 4090 has.

Clocks are higher than expected, also considering this is @450W. Performance/W seems to be almost doubled. Scaling seems not OK but this may be also a bandwidth starved part (which may also mean higher SM count parts would not gain much if not paired with adequate memory). All in all, strong showing.

 

[Karnak]

Maybe its 450W at stock but not in that TSE while running at 3GHz. I seriously doubt that.

They are claiming it was running in "silent mode" (given that they claim it has a cooler rated for 600+ W). We'll just have to see.

It was their claim, according to that thread on Twitter, not mine.

Gigabyte GeForce RTX 4090 cards now listed in Australia - VideoCardz.com

2 Australian retailers have put up Gigabyte 4090s on their website. The prices are probably placeholders since there haven't been any legit leaks about what nVidia is planning on charging.

Maybe on an open bench?

AD106 only has 8 lanes. This is a change since I think normally the 106 chip has usually has the full 16 lanes.

 

[Mopetar]

Is this legal?

What would be illegal about making up something to trick a bunch of rumor sites or YouTube channels into posting it?

No one is paying for a fraudulent product and the only thing that might be considered damaged is the reputation of the people who were duped, but no one made them cover it.

And now a possible leak of the Zotac 4090 and it's box.

Only thing I could notice is that it confirms that Ada is PCIe 4 only.

What do you mean PCIe 4 only? If you plug it on a PCIe 3.0 bus, it won't work? Why?

Since Gen 5 is pretty rare out in the world I imagine they decided the gains weren't sufficient to spend the money on a Gen 5 design.

 

[Aapje]

It's questionable that you would see any significant gains with PCIe 5 and it probably saves a bit of money. I'm very interested to know what AMD will do. They are typically more eager to adopt a new PCIe version, but they might also skip it.

If so, that makes X570E rather silly, though.
