However professional programs like CAD use both DP and ECC memory you can't afford it to make a rendering error on a 200 million dollar structure.

 

so then would this GPU even be aimed to a gaming consumer market?

The card maybe not but they tend to re-use the chip throughout every segment they can maybe with minor adjustments.

Typically, workstation cards like the FirePro series and gaming cards like the Radeon series use (mostly) the same ASICs with different features turned on and off. The drivers are also different. That is what I was getting at with my post you quoted--the ASIC could be built for ECC so that they can release workstation cards with that feature while the gaming variants would just not use the full bus width. You could release 576-bit workstation cards with ECC and 512-bit gaming cards without while using the same chip as is common practice. Either way you'd end up with "round" capacities which was the original question I was answering.

How about no? I'd be the first to buy one but no...

According to the information there, the die is only 410 mm^2 - the largest, assuming that spec sheet is true, was the 2900 XT at 420 mm^2. Sadly that chip did not work out too well for AMD.

It seems to be that ever since the 4800s, they've been making larger dies; I would not be surprised in the future to see an AMD version of the Titan, assuming this one goes well.

69x0 cards were 389mm^2, I don't see why a 410mm^2 die should be considered even remotely extravagant. If anything, it is very possible that a supposed 79x0 successor on a 28nm process (a refresh so to speak) will be around that size (~420mm^2 actually), given that cayman also got a ~15% die increase over cypress.

Open-Source AMD Driver Gets "Hainan" GPU Support

http://www.phoronix.com/scan.php?page=news_item&px=MTM3MTA

The open-source AMD Linux graphics driver now boasts support for AMD's next-generation "Hainan" GPU products, a.k.a. the Radeon HD 8800 series.

AMD Hainan is rumored to be the performance GPUs making up the Radeon HD 8800 series with the HD 8850 "Hainan Pro" and HD 8870 "Hainan XT" products initially.

I thought there was no sea islands anymore but going straight to VI?


ps. I was really looking forward to upgrading my 6850 this christmas with a 20nm chip! lol

The 8xxx cards are supposed to be OEM rebrands of 7xxx cards.

Semi Accurate has basically debunked this Volcanic Island "Design Leak".

So what we have is an illustration to go with a forum post from last fall that was discovered by tech sites. These technology “news” sites all appear to have taken an image from a random Flicker site, now pulled to avoid more stupidity, that was not claimed to be real by the author, not meant to look like an official AMD slide in any way, and explicitly posted under the authors handle on our forums and turned it into their own “news”.

“I thought I made myself clear that I was just illustrating a point in transistor scaling from 28 nm to 20 nm when I first posted the image on the forums: http://www.semiaccurate.com/forums/showpost.php?p=168728&postcount=7″

A lot of people have mentioned this, yet, some choose to believe that this was not only real, but coming end of the year.

Prediction: Between Oct - Dec. there will be a refresh on 20nm, GCN 2.0, 20nm will come next year.

We haven't had any news of any chips taping out on 20nm from either camp. NVIDIA is just barely getting their refresh out now.

Amd is in stealth mode right now, even with their upcoming frame rate driver fix. I like it.....
