As in March for the 448 piper (20% faster than HD 5870) and September for the 512piper which would trade blows with the HD5970?
Ati will most likely release a HD 5890 come May which will significantly narrow the Fermi performance lead to just a few %.
If ATi can get a 2GB at least 950Mhz or even 1Ghz HD 5890 out of the door it will be the first time I have purchased an ATi card since the Radeon 9700 Pro. If not then I will most likely stick it out with a working GTX 285 OCX I receive from RMA until something with more VRAM comes along.

It seems both cut-down and full part will be launching in March, placed on top of the GTX275 in the price list. Dual Fermi a couple of weeks after that. can't say if the cut-down part is 384 or 448. TDP for the "big" part should at least match HD5970.
Really?Quote:

Could this be an Ultra Part?
What everyone needs to remember is that the ASUS M.A.R.S was essentially a rebaged Quadro FX 5800
Whatever is coming in September, is going to be huge (6GB of VRAM for a start). Could this be the dual Fermi?
Perhaps the cut-down part has 1.5GB of VRAM, the full part 3GB of RAM and the Dual part "6" GB?
It would make sense as OpenCL, DirectCompute, CUDA etc love the VRAM too you know..

HD5970's TDP is 300w if I am not mistaken, so as far as I know there can't be a "at least as high as hd5970" situation, there's no higher than 300w in pcie tdp... plus, how is dual Fermi gonna be made with such TDP's with the single version, I don't know.Quote:

I believe a dual Fermi would come soon. One of the reasons why NVIDIA has managed to built quite a number of loyal followers in the past years was their "fastest card on the market" claim. I don't think NVIDIA would want to lose that claim, especially after all the heat Fermi has taken.Quote:

i'm still running g92's, they've served me well, it's a good product when priced right. i just want to see at least 3 gf100 based geforce cards.Quote:

Yeah, right...Quote:
GTX395 is 60% faster than GTX380
GTX395 is 70% faster than HD5970
Release Date : May 2010, Price : 499-549 USD.
I'm talking based upon the points neliz made. He said that a single Fermi's TDP would be 300w. Now you could take a stripped Fermi part and downclock it even further maybe like you said to make a dual Fermi, but it would still have a TDP of 300w and it would be SLI.Quote:

LOL indeed. 70% faster than a 5970 at the same power level? $500?Quote:

Right.
499-$549? FAIL, also 640-bit? Man if it could pack all those things listed at 40nm then this card would have to be like probably at least 35~40cm long which I doubt will happen.
It could be as tall as MSI 5870 Lightning! :DQuote:

Remember nvidia says "up to" 512 cuda cores.. and they don't want to be caught lying. dual fermi part is definitely a number of weeks after that.Quote:

Now that rajiff the thief (whatever) guy can either deny or confirm it, but in march we will see one hug *ss fermi based chip and one of more decent size. It would also be nice if the confirmed the three different part available in this and the next quarter. So far he seems to be telling me less than people that actually are under NDA.
their single card (GTX380) won't gain their performance crown, so I wouldn't be surprised if they release a dual-gpu based fermi shortly after their fist single gpu cards, but lets see GTX 380 tdp and temps goes...
as annihilat0r pointed out there's just no space in 300W budget to squeeze two GTX380's... hell even two 360's would be challenge, and that would require significant mumbo-jumbo on binning side... but... they can always stitch something like they did with EVGA... you know GTX275+GTS250 freak... but this time with GTX360 and... err... GTS340!? They have know-how, and they'll have bunch of 360's if rumored yield is true ;)Quote:

Whatever they do to castrate Fermi to put 2 of it into 1 card, it must still be 300W. So I am guessing that Fermi won't be 300W but something like 240 or 250W. That way, a dual version might be at least somewhat faster than the GTX 380.
or they can create card that would require completely new ATX power standard, and push it for broad acceptance :)Quote:
