So, do we know anything about RV670 yet?

Easy. Whatever they have to in order to win the important benchies

 

....

 

pfffffft

I'll believe it when I see it.

 

But still that would be great news. With ATI being late the last few times, its nice to have them on the early side1

 

Certainly it would be great news. Sadly, their track record the last couple years leads me to classify this rumor in the "unlikely" category.

 

I think it's likely actually, since the chip is supposedly not much different than R600, thus not a huge overhaul.

 

Word is that there will be a RV680, consisting out of 2 RV670's, with quite good performance compared to a R600 CF. Q4 and Q1 will be quite interesting.

 

RV680 or R680?

Jawed

 

RV680. It was just announced unofficially.... R680 is no more if I'm correct.

Oh and it's a beast. And RV670 is on track for a launch in mid November.

 

Ah the irony, a process node that's kind to ATI and ATI decides to drop the top GPU apparently planned for it.

Anyway, I can't get excited by this stuff. Something whose only ambition is to compete with 8800U, or 8800GTS in the case of a single RV670, is yawnsome.

Jawed

 

Paper or hard?

 

Well, it kinda makes sense to drop the top GPU planned for the processnode if you know that there's another top end (next generation) GPU coming soon.

If the rumored performance numbers given for RV680 are true (eg up to 1.5x faster than a HD2900XT CF), it might actually be a very nice solution until that next generation GPU comes along.

• RV670 GPU is 13.38x14.47 = 194mm2
• I count 1289 balls on the package

Thats very small, so its not a whole r600 at 55nm.
On the link confirmed card with the reference dual slot cooler is the gddr4 version.

 

If 55nm was always lined up for Q108, then the gap between it and R700 (Q208) would always have been small. This doesn't seem to quite add up to me. Unless R700 was originally Q408.

Maybe R650 was supposed to be 65nm in Q207 (after R600 in Q406 on 80nm - but then R650 got canned). I'm just thinking of the more traditional May/November timings for releases, implying that R700 was always scheduled for Q208 (May) and 65/55nm have slipped back, with 65nm being "skipped" as quickly as possible.

For those willing to gamble excessively on drivers, yeah.

256-bit bus I guess, half the MCs (or they're half-sized), half the ring-bus size, smaller ring stops?

Jawed

 

My quess its have "only" 240SPU.

 

Afaik it's still 320 streamprocessors. That would also seem likely since targeted performance is comparable (or even higher) than a HD2900XT.

 

ATI is a great company.

Full 320 Stream processors, as whole, is as fantastic as Customer would like it.
I was informed that Nvidia will not launch any fully enabled G92( From 8 TCPs cut down to 6 TCPs) in 2007.

 

420mm2 (die size of R600) / 80^2 * 55^2 = 198.5 mm^2.

So 194mm^2 for RV670 looks right on target to me...
If it doesn't have a 512bit memory bus (can you fit that many external connections into a package of this size? I've no idea) that alone would probably more than make up the (very small) theoretical size difference (though I'd expect it to have UVD but that should be small, I think there was some number quoted for that somewhere but I can't remember).
