Why?
Think of 770 -> 790 as X1800 -> X1900 (I think the 20% is really, really conservative. But that's just me.)
No shrinks, just a new chip with more oomph than just clocks *cough*

GT212 won't come before Q3 09, right ? If RV790 delivers its promises, it WILL be a kick a$$ card in the market for a while -a bearish market it is.Quote:

Whereas here, the 4870 was, and still is a very capable contender, and the 4890 is just a response to nvidia's refresh.
Also, I wouldn't hold my breath for this being 40nm. As others have mentioned, TSMC's 40nm node has been plauged with so many issues, and I think that ATI will not want to fumble the ball here when it comes to their "highend", or forefront products.
If GT212 is needed to beat RV790 then Nvidia is in a lot of trouble. GT215 or GT214 would be a more probable competitor.Quote:

TSMC really dropped the ball with 40nm
I think that's what ATI already did with the passage from RV670 to RV770.Quote:

I believe it's a 40nm card because if it is a 55nm i don't see the reason for the delay. At 55nm they should be able to foresee what they could and not do due to power limitations several months ago. So they could have launched the 55nm r790 at january as a response to the 285 which first benchmarks was available since the mid december, and ati already knew what would be 285 perfomance more or less and i don't believe they started r790 design after 285 was released. All that of course based on the fact that r790 is not a complete redesign on 55nm because it doesn't make much sense and either way even that wouldn't delay so much as april, since 55nm is a known process.
I'm hoping this means a $200 4870x2. :)
I'm still waiting for that price to get crossfire.Quote:

If it is a 55nm why didn't they released it earlier. As i said before i think they could foresee what they could do in 55nm, so ati should have gotten the r790 ready, and released it as soon as 285 released as a response. Otherwise i don't see why would they delayed it so long.
Trust me, he brought up a similair, short, and stuck-up statement in the last RV790 thread.Quote:

Don't get me wrong, I don't believe that it is 40nm. Just telling you "how he thinks it is wrong."

RV790 leaked info has a voltage 40% higher than what 40nm supposedly uses.
:rofl: Do you know where ATi's HQ is located? Toronto. :ROTF:Quote:

I didnt mean it as in nvidia will have something faster, what i meant is by releasing this, then 6 months later releasing the RV800 series (remember 7950GT and 8800GTX?), it is too little too late, which means people who already own a 4800 series card would be wasting money upgrading to a 4890, just like people who own a gtx 280 would be crazy to upgrade to a gtx 285, same thing, different company, as for other people who may want to upgrade, im sure they wouldnt mind waiting till the end of the year for better offerings from both sides, now as i look at the upcoming games for 2009, i see nothing special that will challenge anything higher than an 8800gt as all games seem to be xbox 360/ps3/pc games, which ofcourse means pc users just get a port. Hope this clears up some things. And no i wasnt kidding about their drivers, they suck to me, i know many people love it and thats fine, keep it to yourself, my opinion is ATI cannot make drivers if their life depended on it. Also to add a little something to what PERKAM said, ATI having the edge in the high end, well let me put it this way, i dont think that is totaly true, my reason being, the 4870x2 is two 4870 1GB's put together, so you have 2 mid-high end gpu's together, yes it becomes faster than any one gpu setup, intill nvidia releases the gtx 295 and takes back the performance crown, now if you look at the gtx 295, it is twi gtx 260's with 240 cores enabled running at gtx 260 speeds. So the GTX 260 was faster than the 4870 after all, in most cases. So as far as i am concerned nvidia has the high end for a single GPU which is ofcourse the GTX 285, till a "true" dual core GPU comes out, i mean something that doesnt need a profile or a driver update to work properly, i can only consider a single fastest GPU holder to hold the crown, hopefully you understand what i am trying to say, anyway these are my thoughts i dont expect everyone to agree, but im sure some people share the same vision as me.Quote:

Try to play FEAR with crossfire enabled with a 4870x2 frame rates suck, stuttering occours, disable crossfire and it works better, now tell me what is the point in having the fastest single card, when in reality it is not a single card, it is 2 cards in one, just like crossfire and just like sli. So nvidia had the high end all along by putting 2 gtx 280's together, cuz all the 4870x2 was 2 4870's after all.Quote:

So, you have acquired this info by putting your ear to the wall of their HQ? :ROTF:Quote:

ill definitely get 4890 1gb
but what about 4890x2.. when ?
Very interested in 4890x2 myself especially if all the supposed performance increase numbers turn out to be correct. GTX 285 SLI performance (with superior aa performance) in a single card solution sounds awesome.
Did you know? The people that work @ ATi HQ also live in the same area!! OMG!!! :eek::eek:Quote:
