Hmmm...I took another good look at it and used GTX 285 pcb where the memory chips are stacked as close side by side. I think Fermi chip is probably somewhat smaller then G200-B3 but not by a huge margin.

from this GTX 470 is 5 to 10% faster then HD 5870
oh and the clock is 700mhz :)

You can't determine die size from IHS size.

I wouldn't jump to such early conclusion since we all know Crysis is obviously optimized and runs better with Nvidia.

OMG its real!!

And all this time... what fools we were...

Now I want the nVidia CEO to make it look and work exactly as when he "first showed a retail board" to public ;)

Odd things about the Fermi photo:
- So very few capacitors/inductors/power-transistors.
- holes/silk-screen around inductors for different configuration?
- what's up with silly putty on two of the MOSFETS?
- At least 15 holes in PCB, 9 just around the IHS!!
- Notice what seems like space for 3rd PCIE power connector - a 6pin.
- Big ass clock generator in bottom left, and some weird black 4 pinout on bottom right (guessing the white one is for fan)...

Anyone else notice the 8pin+8pin+6pin possibility on the GTX480 PCB?

Liquid, Charlie didn't write that latest piece on SA.

Edit-Deimos, that "silly putty" is thermal tape, aka TIM.

Still not one image of an actual fermi card with the cooler on it. This is just bull:banana::banana::banana::banana:

At first glace thought they use same PCB for GTX470 and GTX480.
But the one in picture above looks shorter (and obviously 6+6 power).

Strange, but it has 10 DRAMs?

EDIT: Why do both 470 and 480 require the big fan holes in PCB? And 470 has them side-side, and 480 top-bottom. Wouldn't 2 fans be better/simpler??

According to Vantage, it's around the same speed to slower than the 5870 ;)

(pointless to compare scores without specs anyways)

From the pic, you can make it out. It says 625 core.

And 1250 or 1296 shader clock

GTX 470 = 320-bit = 1280 MB = 10 DRAMs

GTX480 = 384-bit = 1536 MB = 12 DRAMs

No?

320bit bus. 10x128 = 1280mb.

No?

Since nvidia uses 64 bit memory controllers,

gtx470 = 5x64 bit (320) = 10 drams x 128 = 1280
gtx480 = 6x64 bit (384) = 12 drams x 128 = 1536

Each controller utilizing two drams

So are we guessing what these blurred out numbers are? :D

Or do we already know?

I guess they are 625, 1250, respectively. ;)

snip..

And so this box pic is fake? Maybe just a misprint in the graphics? Many of these box are uses the same template of older box designs. Maybe they just forgot to change ATI to and NV bullet point. :confused:

Can be real, my xfx GTX 275 was sold in a box that proclaimed it was GTS 250 on the back and GTX 275 on the front :yepp:

Gigabyte probably hurried up to get a box out for CeBit, and boxes are often mistake filled anyways

Yeah, they use other boxes sometimes, but selling nVidia GPU in a ATi-box is crossing the red line.

Those pics are real. It's just gigabyte's mistake. ;)

It's not even sure if Gigabyte themselves have the design of the card ready... Printing the box is freaking easy. They did it to get some attention (which worked, obviously, even on a tech forum).

Lacking marketing information from NVIDIA, they probably copied and pasted too much from the other team's marketing material ;)

Move along people. I wonder why you're all so excited about a box launch.

The Chinese name card is most likely GTX470,but I'm not sure.

So, it still can't play Crysis?

If these are true and for a GTX 470, it's safe to say that it's between a 5870 and 5850 in lower settings and it more or less catches up with 5870 when image quality increases

so as those of us who knew ;) the GTX470 runs on par with a 5870, and the GTX 480 is 10% -15% faster, at the same TDP.

I love you Nvidia :clap:

Woah, not good for NV at all... :(
03-03-2010, 07:38 AM
annihilat0r

well I think it's not bad, this would mean that a GTX 480 could be avg. 20% faster than a 5870 with the "right" settings... Of course if you were expecting a 5970 level performance it will disappoint you, but I personally never expected such a thing

What do you smoke? Can I have some? :)
