We know that RV770 is in production and that things have been going quite smoothly up till now. We've been looking forward to seeing the first cards at Computex in June, but it seems like the card will be ready even sooner. We've been hearing stories about a launch in late May, and more stories have popped up now saying the same thing. Since GDDR5 is still at an early stage it seems that the first models may use GDDR3 instead. This should put RV770 cards at a very interesting price point. Yields are good and GDDR3 chips are plentiful. Let's just hope that there is something to the specifications circulating in the east, and we might have a real killer at hand.

You know, I really like what ATI is doing, it may not be the GDDR5 varient we have read up on, but, if it is just enough to knock off the 9800GX2, and, with ATI's very favourable pricing scheme (apparantly will cost same as 3870x2 does now), like the article said, we 'have a real killer at hand'

What's wrong with using GDDR4?

Think the basic argument against it is, using GDDR4 would impose a fairly substantial price hike on the part, and a minimal performance boost. So they dont bother, apparantly nvidia are not going to dable with GDDR4 atall for the very same reason.

Whilst on a similar topic, what does the G stand for? And why is (G)DDR3 so common in GPU's yet hardly used as RAM?

Just means graphics ''Graphics Double Data Rate'' followed by what ever version it is 2,3,4,5 etc).

Though am not entirely sure on the whole RAM thing. But then, GDDR3 is specific to graphics memory, it isnt the same thing really. Atleast, that is my understanding of it. Theres a lot of GDDR3 chips available as well, so that contributes to the cost effectivness of using it in GPU's

GDDR3, Graphics Double Data Rate 3, is a graphics card-specific memory technology, designed by ATI Technologies.

It has much the same technological base as DDR2, but the power and heat dispersal requirements have been reduced somewhat, allowing for higher-speed memory modules, and simplified cooling systems. Unlike the DDR2 used on graphics cards, GDDR3 is unrelated to the JEDEC DDR3 specification. This memory uses internal terminators, enabling it to better handle certain graphics demands. To improve bandwidth, GDDR3 memory transfers 4 bits of data per pin in 2 clock cycles.

Bell +1 for this news. I'm getting the X2 as soon as it hits the market.
