RV560/570 Gemini roadmap

Isn't that the Asus 2xR520 mockup?

Is it a mockup? Afaik that was the Asus X1600 X2 (although they did mirror the picture). Asus supposedly also has functional models of the X1800 X2 and X1900 X2, but only the X1600 X2 would go into MP (from what I've heard). And the X2 cards would be able to run in "4GPU" setup.

Here's another pic of the Asus X1600 X2

If that is dual RV530XT (~85W), why would it need an external power plug if R580XTX (~120W)doesn't?

The external powersupply is optional. You don't need to use it. You can just as well connect it to your PSU.
 
The picture you see is of Asus' Dual 1600XT setup..
I think it is due launch somewhere in March as a prelude to Gemini.

Besides wanting to know if it works like SLI (i.e. Quad VPU) I'm more interested in what looks like a Carbon Heatsink to cool the two 1600's.
They can be passively cooled in single slot so I wonder about about this setup..

I'd expect quad CF to be a reasonable expectation for the near future (under the monkey see monkey do perspective which works both ways).

If the heatsink should be more than the board would actually need even with two chips, it could indicate a very potent overclocker.

ATi had dual core cards before nV, back with teh old rage that was killed mostly by the lack of XP support. and there were alot of multi core ATi "proffetional" solutions, since they were supported since the R300's. so i dont realy see a copycat pattern here.
nV's dual cards are designed by OEM's, i dont think there is much of hardware limitation to created dual CF cards.


IIRC, the Geforce 1 could do "multi-chip" too.

I remember a least one professional solution based on R200 - CAE Tropos:

Hmm, at the very bottom of this page our Chinese comrades are claiming RV570/RV560 will be 12-1-3-? and 8-1-2-?, respectively, with both sporting a 128-bit bus. Any buyers? :p

I think Dave already suggested that the last number will not be a 1 -> 2.

RV570 12-1-3-2
RV560 8-1-2-2

I'm guessing RV570 will be ~260 million transistors (on 80nm) which I'm guessing is enough for people to confuse it as a 256bit chip.

You just blew my mind. (Well, you and HKEPC, upon rereading.)

Fudo thinks and Xbit announced that RV570 is 256b, so maybe it is and RV560 is 128b. And maybe, as Dave suggested, RV570 is straight outta TSMC and RV560 is outta UMC.

Actually, didn't ATI use UMC back in the RV250 days? Have they used them since then for any GPU? If not, would it be reasonable to drop an ALU per TMU for higher yields (thinking like Jawed, here) in getting reacquainted with them?
 
Um, a tad off topic, but is it me or does that Asus concept look nearly identical to their dual 7800GT board?


Also, I like the size on that GeCube, anyone think it'd run in a non-CrossFire chipset equipped mobo?

It was RV280 (9200) that UMC fabbed back then. Since these would also be relatively high-volume parts, getting UMC's fab capacity back on board wouldn't be a luxury. Obviously the design team has conceded that 8-1-2-2 would be far more balanced an approach, now that we've all seen where RV530 falls short. And RV570 could shape up to be a formidable part for the mid-range segment even with a 128-bit bus, assuming that ATI can depart from its recent history of being too late to the party. Unless that roadmap has changed, volume production in July/August is not going to change their situation at all.
