The new products will hit the shelves before Nvidia launches its GT-200 cards

AMD will premiere its upcoming generation of RV770 XT and RV770 PRO graphics cards during the Computex show in Taipei. According to industry rumors, the graphics specialist has been shipping sampling units of its RV770XT chips for some time now, as the new GPUs are extremely stable.

Moreover, the new cards will start shipping sometime in the last week of June, as previously planned. Unlike its arch-rival Nvidia, AMD did not have to update its GPU micro-architecture. While Nvidia is reportedly placing orders for both 65- and 55-nanometer GT-200 graphics processors, AMD already has working samples of its 55-nanometer RV770XT.

However, Advanced Micro Devices also plans a redesign, but it mostly pitches at replacing the RV770PRO with GDDR3 with the faster and more efficient RV770PRO with GDDR5 combination. Earlier this week, Qimonda announced that it was ready to ramp up production of GDDR5 memory and mass quantities of GDDR5 chips are expected to be available sometime during the third quarter.

It is alleged that AMD will initially deliver its RV770XT paired with GDDR3 memory, then add a new GDDR5 version of the cards as GDDR5 gains more ground. Replacing GDDR3 with GDDR5 will require additional tweaks to the printed circuit board, as the two memory types come in distinct packages (GDDR3 comes in a PG-TFBGA-136 package, while GDDR5 sports the PG-TFBGA-170 technology).

The RV770XT graphics card will also sport a 512-bit memory controller and will be bigger than the previous RV670XT offering. According to the company, it will feature full support for Microsoft's DirectX 10.1 technology. Since it will run pretty hot, the stock graphics card design comes with a bigger cooling solution.

At the moment, there are no pricing details about AMD's upcoming lineup of graphics products, but since Nvidia priced its GT-200 offerings in the $499 space, we'd expect AMD to follow the same pricing trend.

hmmmm.. no gddr5 to begin with, but a 512bit interface..

i see some bascially AMD is waiting for the memory to come in?
what happened to all their GDDR4 memory?
and what happened to all that stuff about making it fit the 140/110 TDP?
512-memory interface? hope AMD knows what their doing.

512bit interface is complete BS. I don't believe they would use a 512bit interface AND GDDR5.

512-bit + GDDR5 = overkill, and not mention unnecessary added costs that either eat margins or is passed along down to the consumer which might hurt sales. Also, what happened to the RV770pro being released in late May?

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.

They should put 512bit to ddr3 cards. And 256bit for GDDR3. But i trust ATi.

Fixed

It still adds extra costs to the cards, they'd have the same performance, with different setups. Their R&D doesn't have enough money to do that!

The "holdup" with the HD 4xxx series might be that the nVidia 9xxx series are faster(plz don't flame, just a possibility) and ATi is trying to overclock(?) their own gpus, but again that's just my big mouth shouting something just to be heard

There is no doubt that NVidia's 9900GTX will be faster than RV770xt, the problem is, it will probably be 5-10% faster and cost 30-40% more.

That's allways the problem with nVidia: high prices for a small difference.
