Probably, but who knows if it's a 65nm part, it may just be a final respin on 80nm that they are unwilling to wait the extra time to complete, so they're mass producing an early revision first just to get it out there. Remember R520 and the crappy metal spin batch that was rumored to have ended up in at least the first batch of XL's (Which I think was FUD, but I'm sure you know what I'm talking about)? Perhaps this time they're just going to get the darn thing out the door and will give us the final spin with a nice ol' 50 attached to it. Hmm...X2800 to compete with G80 in Q2, X2850 to compete with G81 in Q3, and X2900 (65nm/R680) to compete with G90/G85 (65nm) going into the end of the year? Sounds plausible enough, although...
Still, I do smell FUD. Wasn't A12 supposedly NOT going to be the release version according to several sources? Either that's flat out wrong, or plans seemed to have changed.
Still, even stranger enough, there was that rumor from Level505 (please don't hit me) that they were going to release the current revision, and revise the chip and release a better version a few months later. As much as we'd like to hate that site, that lines up more or less (except for time frame and only GDDR3 on the early model) with this current rumor. I suppose it's possible plans (launch dates, versions launched) have changed, and l505 could've been right, and now they will make a GDDR4 version with the first chip. It may be or have been a fluid situation depending on how quickly they could get what turned out to be A15 produced, amongst other things. The fact UFO seems to have been planned, cancelled, planned again, cancelled, and now on track again lends credence to that.
DAAMIT, I'm confused.
