Sony Xperia S3DC 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.

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?

Sony Xperia SIn 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.

Sony Xperia Sthe more likely those will use either 20nm or 16nm. :rolleyes:

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.

xenocideYou 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! o_O 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....

HumanSmokewhy AMD would go from building large GPUs on 20nm

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

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

Not necessarily. You had a benchmarked engineering sample.

I am still not quite sure about this.

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.

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.

HumanSmoke...

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? :D
