NVIDIA ‘Ampere’ 8nm Graphics Cards

humbug said:
Yeah, the 5700XT is a middle of development GPU, half old GCN, half new RDNA, its the GCN part thats holding it back from scaling, GCN is horrible for scaling.... they pushed it out half finished mid development because its all the had to stay relevant with Turing strutting its mighty stuff.

Despite this it shows so much promise, with 40 CU's its as fast or faster than a 60 CU Radeon VII at the same clock speed, and the Radeon VII has about double the memory bandwidth.
Its a glimpse of what's coming once all the GCN crap has been ripped out, the IPC is at least on par with Turing, the XBox Series X proves they have scaled it to at least 52 CU's, it has a very clever and capable way of dealing with Ray Tracing, the PS5 proves it clocks to at least 2.3Ghz.
Whats more that XBox is a 330mm2 die which includes a Ryzen 3700X and a total package power of 170 Watt's, take out 40 / 50 Watt's and 80mm2 for the CPU, what are you left with for this 52 CU <2080TI RDNA2 GPU? 2500mm2 and about 120 to 130 Watt's

(Speculation) RDNA2, 64 CU's, 2.3Ghz, a small 10% bump in IPC.... that's a monster, one that should worry the Leather Jacket tho i still think Nvidia WIL WIN. but Jens will sweat buckets to get the win and not by all that much.

That's my prediction.

Nvidia were always going to throw everything at Ampere to ensure it won at all costs. If Nvidia retain the performance crown, what will be the cost for their approach of 'stop at nothing' to win.

If they beat AMD by 20% but use 80% more power, that's not a good look for a GPU company that previously boasted hard about their efficiency.

The difference there though is that these are all generally heavily overclocked AIB cards, hence the larger coolers but the 3090 we've seen pictured is the bog standard FE version.

How big would the AIB coolers have to be on this card if they were able to create KP versions or similar? It's already massive, so I dread to think how big they would have to go :D

Indeed, they are heavily overclocked cards and on the KP even heavier because you can unlock the voltage. I haven't done that yet (there's absolutely no need, the card does 2150mhz on the stock stuff) but later I may as it will give me extra perf when I need it (once the warranty is gone). But yeah, that's a big SOB for a "reference" card.

As for AIBs? I bet they are ripping their hair out designing a third party PCB right now tbh. That cooler (1080Ti KP, 2080Ti KP, HOF cards, certain Aorus cards etc etc) is about as high as you can go (140mm) without making it incompatible with nearly all cases. Apart from gert big heffer cases of course.

But. There are going to be more issues with it than that. Firstly I have been using vertical risers for about two years now, and my Vega 64 would not work in any of them. I tried Cooler Master, Phanteks and another one and it just crashed out once it started pulling power from the lanes. And given most will want to VM this thing? yeah it may be an issue.

Another issue? well, back in the days of the proper guzzlers (590, 6990, 5970, 480 etc that all broke PCIE power spec) the 24 pin cables would melt. The 12v lines, basically. Those who have been around for long enough will remember, and especially the nut cases like myself who used to run SLi or CFX with these guzzlers.

It made most manus have to redesign motherboards (after X58, which were the culprits for melting the 12v wires on the 24 pin) and add in extra PCIE power sockets on the board. This was common on X79. You had either an 8 pin PCIE, 8 pin EPS or 6 pin PCIE to prevent that happening. However, in recent times? that has all vanished because GPUs stopped shorting out the national power grid and became much better behaved.

So fully expect to need a new PSU, possibly new case* and if you are running SLi or Nvlink? probably a new mobo also.

It's going to be at least 300mm long, with the power connectors looking like they are going to be in the end like the 1080Ti KP I listed above. Meaning all but very deep cases will not even hold the sucker.

Indeed, Nvidia just want it more, and they have the architecture...

My very rough measurements/scaling put it at around 135 high and 335 long, which as you say isn't any higher than current "big" cards but is one of the longest I've ever seen.

Yeah there have been limits to stupidity before now. At the end of the day it has to fit in at least some cases.

Maybe Samsung 8nm is a hot piece of sh.t that requires such a massive cooling.

I just wrote an epic long post on another forum about it, but yeah it will eat power.

I strongly suggest a watch, as it explains it all in great detail. The upshot "Short" answer? yes, it will consume lots of power. Nvidia would not have made a card like that or a cooler like that with power connectors like that for fun.

The 2080Ti Kingpin? wasn't done for fun. It was done to break records. LOLably I bought mine for the simple reason it came with a 240 AIO and I usually water cool my PCs but really couldn't be assed this time around. However, what I can tell you was it was a sod to get it running. I bought a 750w Strix PSU (Seasonic) which is really lovely but because of the death of SLi and CFX it only had two 8 pin PCIE. So, I had to convert the extra EPS (thankfully it even had one or I would have had to send it back and get an even bigger PSU !) to the last 8 pin just to get it to fire.

Then there is all of the talk about this 12 pin, etc etc. Nvidia have not done any of that for the fun of it, so they can show off, or how their end users can wave their willies about over it (see meme haha)

3 8 pin on a "reference" card is pretty extreme. In fact no, no it isn't, it's VERY extreme and there will 100% be a very good reason for it.
 
Reminds me of the Intel Socket 3647 systems, the Asus Dominus board with no less than five 8-pin CPU power connectors, and a six pin just for good measure! :D
 
It's not single fan, mate. Well, not the 3080 at least. It has one in the "back plate " side too. Looks like dual 92, 100 or what not.
 
Well I just had a result. Went to check on my GPU fund and discovered £400 I’d squirrelled away two years ago.

Should make a purchase slightly less painful. :)

Current Zotac card is 320mm long. Could see some AIB’s being up to 400mm at this rate. Or will the triple slot design make that unnecessary?

Suppose it depends how good the FE is. That rumoured $150 cooler could be as good if not better than AIB designs so AIB cards may not need to be much more sophisticated.

Just seems surprising, if the photos are true, that it only has two fans on it but it’s still a triple slot card.

Think we’ve all come to the conclusion that it’s going to take some serious cooling. Wonder if we’ll see the first ever quad fan card from an AIB.

What's the opportunity cost of that £400?
 
Oh well, if their performance doesn't justify the prices, I'll see if AMD can offer a good upgrade from my 1080Ti.
