NVIDIA GTX 280 Series 55nm cards...How will they perform???
 
I heard in late August 2008 that NVIDIA will release their GTX 280 Series cards with with 55nm technology. How will it perform and what are the official specs? This could be the upgrade I've been waiting for since using 8800 Ultra's in SLI.

Let me check my magic sphere... Yep, they'll suck...

Official specs haven't been released yet. They should perform well, but in the end they will just be highly overclocked 280's. Of course, they will overclock well beyond that due to the small manufacturing process, but nothing groundbreaking here AFAIK. Good competition for the 4870X2 if it's the beast we've been led to believe. I'd be very surprised if they ended up faster then the X2, probably close or equal in some cases, but nothing more. The real benefits of these cards will come not in pure speed but lower heat/power consumption and hopefully a low price all in a reliable single GPU package.

Agreed.

If they tweak the number of gates in the chip like from G70 -> G71, they could raise the clocks by a nice margin. Personally, i do not expect more than 700/1500, and prolly they will reuse the same memory chips at the same speed.

The memory chips are certainly not lacking though - 2.6GHz is common.

I believe they're going to be AWESOME but since it's not around the corner this tread belongs more in the rumors forum.
If the GTX 280 55nm was going to be released in August one should be able to Google much more details about it. Maybe even some previews on Chinese sites.
Therefore I believe we will see the GTX 280 55nm towards the end of the year.

Are they going to be GDDR5?

I wouldn't hold your breath. 55nm isn't that much smaller than 65nm and on top of that Nvidia isn't getting much of a shrink or much of a power reduction out of 55nm compared to 65nm, as seen by the 9800 GTX+ previews on anandtech. I don't think they'll get below 500mm^2 and if they did it would be just barely, maybe the size of of the G80's chip, which is still huge.

The power reduction would be the bigger issue, because that directly relates to clock rates, if they are only getting 3%(see anandtech) power reduction then likely clocks would only be slightly better, probably stock clocks would be in the range of the high end GTX 280 OC boards that are out now. I still think they're holding out for 45nm or 40nm, in 1st or 2nd quarter of '09.

The only good thing will be they are cheaper to produce due to the die size so will be more afordable.

I don't know about the memory thing, you can't push GDDR3 much farther than they are now. I think only Samsung makes GDD3 faster than the 0.8ns chips they are using on the GTX 280, and even then only barely, 0.77ns, which is 1.2GHZ vs 1.3GHZ.

Cooler & less power-hungry GT200 ftw!
