Power regulation on the left? That's really odd.
It's awful!
Doesn't that mean we're expecting around cypress class performance for Bart? That's good news to me.
Well with that said, one crossfire connector. Looks like triple-quad crossfire is only for the higher ends. Good decision if you ask me, driver support might be better.
that could be good in some sense. the hot air after your gpu is cooled down is used to finish off cooling the VRMs, since they dont need to be nearly as lowQuote:

I wonder how big the chip is, considering that GF 106 is ~240 mm with less than Juniper XT performance, if AMD can squeeze ~HD 5850 performance into a 260-280 mm^2 chip, that would be great and a serious knock down to nVidia, considering GF 104 360 mm^2 diesize that got owned badly in the efficiency department, first by 330 mm^2 Cypress, then furthermore by this baby giant greenbat killer.

AMD's next generation mid-range GPU is code-named Barts. As previously revealed Barts will be the first graphics circuit to market in October, but it will be named Radeon HD 6800, while Cayman will be saved for the Radeon HD 6900 series.

According to other sources to NordicHardware AMD will start shipping reference cards to manufacturers and partners this week, for testing and evaluation. We can confirm that several manufacturers have tested the card and performance is said to be on par with Radeon HD 5850, but we will have to return with more details on the performance of the new mid-range cards.
idk, calling something a 6800 when it performs very similar to the last sounds a little lack luster.
i wonder if they are going to do serious price drops (30%+) or just push these out at the same price point for 5% better perf and a much better margin and hope we take the bait, again.
Well, think about it, market price for hd5,8k is more than rsp. So market has decided that performance is worth more than amd rsp. So if you make new card, there really is no point price it lower for similar performance.Quote:

I hope that Bart XT, if on performance's level of HD5850, is well below 200$
and I hope I win a million dollars. why would amd and partners give away $100 bucks on every card?Quote:

Only way I could see this as beneficial to AMD is that the card would be something like 6810-40, and cheap, so people will feel like "wow, it's a fast 6800-series card and as cheap as a GTX 460 at the same time". If it's just a 5850 with a 50$ premium I doubt it's going to be received well.
Well, judging on how harshly nVidia whacked GTX 460 street price recently, i think your wish isn't too far offbase, i think Bart XT MSRP won't be any higher than 220 US$. Launched at that price, with ~HD 5850 raw performance and much better tesselation power (the achilles heel of current Evergreen family), GTX 460 1 GB needs to be priced at 180 US$ or lower to stand any chance against this new little beast from ATi.Quote:

It's a mainstream part, it will be priced just above 5770, probably in the 5830 realm, with better performance.Quote:

It is ES! there is measurement points etc in board.
so? why would you design an es board that probably has a lot of noise on the video output signals?Quote:

Sapphire has had the VRM in between the GPU and the display out, so nothing too strange. Not sure why they would do this electrically, though.
Again, good job AMD. :down: Replacing HD5700 series and calling it HD 6800 series.
Well, or maybe now they are going back to their roots with smaller and cheaper chips and sweet spot strategy.
Don't be so quick to judge.Quote:

To confirm if the noise is real or not. Theory takes you only that far...Quote:

So now just focusing on smaller chips to sell lots of them during the christmas and H1 next year, they can drop in a real jawbreaker with 28 nm flagship chips.
Well, guess it gains them better money to make as big leaps as possible all the time, rather than now focusing on small, cheap chips and sell them with very good perf/$ to gain market share, then drop the real leap to the table with 28 nm. Right now gamers don't give a :banana::banana::banana::banana: about ATI, let alone AMD, when compared to Nvidia and Intel. Somehow they need to change that, and I'd bet they have perfect recipe for it right now when Nvidia is at it's weakest.
I think you must have meant less than 50% don't give a dancing banana about ATI, and more than 50% don't give a dancing banana about nvidia.Quote:
