Possible NVIDIA GM200 Specs Surface

[Sony Xperia S]

In theory, it would be fairly easy.

If you'd bothered to read what I wrote it would be obvious that what I was pointing out was that 3DC attributed the name Fiji to the 4096 shader part. I might also point out that many other sources do the same including a well known AMD brown-noser who claims intimate knowledge of AMD's business (although you'll have to stump up a fee to breach the paywall ). Have AMD swapped the names around? were they in the right order to begin with? Who knows, although I'd note that the other parts in the hierarchy don't seem affected.

3DC don't release leaks, they gather information and extrapolate from that. Their membership includes a number of industry insiders, coders, architects. Chiphell on the other hand are a conglomeration like any forum based site.

3DC info is old enough and we have new piece of data which changes initial plans.
Maybe initially Fiji had indeed been scheduled for production on 28nm with 4096 shaders, but afterwards it could be forward-ported to a more advanced manufacturing process, 20nm at GloFo.

In theory it would be ok but in practice, to me, releasing anything 28nm (even GM200) is purely a short-vision decision.

The more you delay in time

The 390x is rumored not to come till summer 2015. Would be a long wait till then with only a low-midtier class card.

the more likely those will use either 20nm or 16nm.

No doubt the design can be ported to a 20nm based process in future (although it seems unlikely with 16nmFF/14nm-XM not too far off), but I still haven't heard a single logical explanation why AMD would go from building large GPUs on 20nm (and if they are being benchmarked now production started at least a quarter ago) then move to 28nm SHP this year. Seems ass-backwards.

What makes it even more unlikely is that AMD will be unveiling the Carrizo APU with the same GPU architecture using 28nm (very likely at this weeks CES). Wouldn't it make more sense to consolidate APUs and GPUs on the same process when the APUs use the same graphics cores as the discrete GPUs?

In theory it would be ok but in practice, to me, releasing anything 28nm (even GM200) is purely a short-vision decision.

Graphics cards have a short shelf life. You build on the processes suited for the task and readily available.

the more likely those will use either 20nm or 16nm.

Unless AMD are really late to the party, I think you're setting yourself up for disappointment. The time frame for Fiji (its test and validation boards being sighted on Zauba some months back) almost certainly seems to point to 28nm IMO. Bermuda hasn't been sighted, so if it's a further development for a later launch then a smaller node is a definite possibility.

You miss the days of Seronxadamus predicting AMD's new CPU's performing 60% better than Intels with perfectly linear scaling and everyone in the software design industry magically coding for 32-threads? The news posts have always been hit or miss, this one is just especially silly.

Uum no! Got nothing to do with just AMD & Intel, I'm referring to the way ppl had discussions on this site, ppl actually helped each other without resorting to a fanboyish mindset, and there were rarely any trolls as well. But I'm going back to around 2008 - 2011....

why AMD would go from building large GPUs on 20nm

No, because Bermuda won't be so large in the first place.

(and if they are being benchmarked now production started at least a quarter ago)

Not necessarily. You had a benchmarked engineering sample.

then move to 28nm SHP this year.

I am still not quite sure about this.

Graphics cards have a short shelf life.

Unless AMD are really late to the party, I think you're setting yourself up for disappointment.

No.
No.

My finances would be actually quite relaxed to wait till real 20nm or 16nm products. Short shelf life doesn't equate to short service in consumers' cases.

Just for comparison, here's a direct comparison of the same situation ( Nvidia top-tier GPU release rumour) from 2009 - the fanboy accusations started flying inside the first 2 pages.

EDIT:

Fiji XT boards began shipping two months ago at least

From tape out to finished silicon takes 8-12 weeks ( Tape out > fabrication > die cutting > chip runtime testing > die packaging > board assembly). Eight weeks prior to 7 November makes it four months - a quarter of a year.

...

The problem with your theory is that if Fiji has been shipping for so long time, there is still no physical evidence or proof, or even a slight hint about coming launches.

So, when will it be released?
