I donno, looks like 6½ to me, and if the same pattern was repeated on the top part of that card, it would be exactly 12...

if the memory chips are planted on between pcie slot and gpu then you are correct.. i've never seen like that before though

Don't ruin peoples dreams!

I hope it is 256bit. I would prefer 64 ROPs and 256bit with fast RAM, than 48 ROPs and slower RAM with 384bit.

i think a bit more and it seems like you are right the white thing on the left of the photo is pcie clips and right side is card's top so upper side of photo is card's left side where dvi and other connectors are so there should be plenty of room for extra memory modules.. thats why there is a diagonal memory module.. if it was 256 bit there shouldnt be any just be L shape.. i believe the card is 384 bit

Yeah that's a novel memory chip layout for AMD/ATI.

There is enough space for a 384 bit interface, if you arrange the memory on 3 sides ( compare here for instance or simply look at a GTX480/580 ). But from that picture you can't tell what it is.

Still wouldn't fix it, when you turned the picture, it seems more obvious that the "possibly memchip spot" (now furthest down, not in line with the rest) isn't a memchip, which would mean you'd need to have 5 + the 2 45 degree chips on top line, doesn't seem likely to me.

HD1950XT had a similar (256 bit) one:

In the original orientation you need the 3 straight ones at the bottom and 3 in a similar arrangement at the top, 4 at the left and the 2 angled ones in the top left and bottom left corners to arrive at the 12 chips for a 384bit interface.

[Jawed]

Yeah that's pretty similar though in this case it's the indented chip nearest the bottom that is the most novel feature here. This seems to be explicitly for compactness, but we can't use this as evidence of >256-bit memory.

But the area near the top of the board between the GPU and the back plane is "quite empty" on HD6970, so it's easy to imagine 10th, 11th and 12th memory chips curving down into that space.

Indeed, brainfart.
Did a quick photochop, doesn't have any perspective taken into account, but seems too wide IMO
Distance between toprow chips is based on the distance between the 1½ chip visible in original

10 mc 320 bit 7950 ?

[Jawed]

Wow there's a memory chip between the GPU and the PCI Express slot interface.

[fellix]

11 DRAM chips?

[no-X]

I see 11, too

[fellix]

Well, unless AMD opted for 32-bit channel architecture--one DRAM device per channel, what we see now is very confusing.

[no-X]

Now I see even the 12th, it's between the green sticker a PCB border (near PCIe)

[Man from Atlantis]

what about the power plugs ? 2x8 pin, 8+6 pin or 2x6 pin ?

[fellix]

[Jawed]

Please refer to this article if you want to see my edited picture (derived from a picture posted above) with numbered memory chips:

[fellix]

LOL, I didn't saw that one!

That one below must be in a very tight fit.

384bit MC seems to be double-confirmed now.

[boxleitnerb]

There has to be one between the GPU and the PCIe interface. If you look closely, the area where the chips are is of a slightly different color:
