AMD Radeon HD 6850 Specs, Pricing Surfaces
AMD's latest graphics processors is just around the corner, and one of the first of them is the Radeon HD 6800 series. The value version of it is the Radeon HD 6850, its most probable specifications have surfaced. To begin with, HD 6850 is based on AMD's new Barts GPU, built on the 40 nm process. The source mentions that the SKU will have 800 stream cores enabled, from earlier reports we're lead to believe that these stream cores are individually more complex than AMD's traditional 5D (4 simple + 1 complex) approach to unified shaders. There is a 256-bit wide GDDR5 memory interface holding 1 GB of memory, the card uses 5 GT/s memory chips, so the memory should be clocked around 1200 MHz (or 4800 MHz effective), if not more. The core is clocked at 775 MHz. Its FOB (freight on board) price is expected to be US $175. Power is drawn from a single 6-pin PCI-E power connector, the draw is expected to be less than 150W. Partners have the option of using a premium blower-type cooler, or a cost-effective heatsink-type cooler. The latter had been pictured a while back, posted below for reference.

Is this is new plan? Nvidia and AMD using coolers other than blower style coolers for better temps or possibly fpr noise reduction
whats up with that?
5850?
I lost track when they started rebranding cards :(
I'm aiming for 5850 replace, maybe something a bit better if the price is right.
460 and 470
the rest is pretty much rubish...
And they haven't picked up that much, loosing steady the last 12 months. atleast here.
The second thing is that AMD cards never really had 1600 or 1440 SPs. What they had was 320 or 288 shader processors, each of them being vector 5 or 5D (5x320=1600, 5x288=1440). Now they are 4D, in this case is 200x4= 800 and these ones are more complex/can do more than the old ones. Through experimentation it was constantly demostrated that the average use was usually less than 4, in between 3 and 4 so in practice the HD5850 could have been seen as a 864-1152 SP card. They have just taken away a shader that was never really in use anyways.
Hopefully they will let the partners redesign that and allow 3 and 4 way Xfire. Or at the very least allow Barts XT to have it.
from the 2xxx
But of corse i dont have a clue what i'm talking about untill the range is out and tested as so far i have no clue what any model will perform like including the 6770/50 as they could be improved on for all i know (faster core clock/memory?). I would hope its just a board limitation not chip/hardware limit to keep the reference models as cheap as possible and that board partners will be able to add a second.
With this name, it should be faster than a HD5850, probably on HD5870 levels. But it looks more like ~HD5770 level performance :(
GTX480, 470, 465 and 460 all of them compete against the 5800 series. The combined DX11 share for GTX460-to-480 is 15,72% against 31.13% for HD5800. Twice the number of cards for twice the amount of time in the market. Thanks to GTX460 that will only raise in Nvidia's favor in October, most probably.
