AMD reveals Radeon HD6850 and HD6870
CHEAP BUT POWERFUL is AMD's sales pitch for its second generation DX11 graphics cards that are also the first products to drop the ATI brand and instead be called AMD Radeon.
Both the Radeon HD6850 and Radeon HD6870 have a 256-bit memory bus, 1GB of GDDR5 RAM, but the similarities stop there.
The HD6870 has a 900MHz clock speed, maximum power consumption of 151W, 56 texture units and 1,120 stream processors.
The HD6850 has a clock speed of 775MHz, a maximum power consumption of 127W, 48 texture units and 960 stream processors.
Both cards can support up to three displays from a single port, deploying AMD Eyefinity technology, and they have two DVI ports, two mini-DP sockets in line with the Displayport 1.2 specification and an HDMI 4.1a port.
AMD is promoting improvements in tessellation technology and describes the HD6800 series as the seventh generation in tessellation progress with improved thread management and buffering.
The cards are now on sale in the US for $179 for the HD6850 and $239 for the HD6870. AMD says those are significant price reductions for the performance provided. The cards are an evolution of the ATI branded HD5800 series. That series, according to AMD, could deliver 6Gflops per dollar while the HD6800 series will deliver over 8Gflops per dollar, a 33 per cent jump in performance.
Games identified by AMD as DX11 that will benefit from the Radeon HD6800 cards include Rebellion's Aliens vs Predator and Electronic Arts' Medal of Honor, which are out now and Eidos' Deus Ex: Human Evolution that will be out in the first quarter of 2011. µ

Actually the 6850 and 6870 are more a replacement for the 57xx series and the 6870 is slightly slower than the 5870 which is about 6% faster in most all games.
Although the HD6870&6850 do have some new tricks like 3D support on their HDMI and displayport connectors and a much lower price.
The real new and faster cards from AMD will arrive late november.
For the price these babies are pretty sweet, and it's good timing to have cheaper but capable cards arrive now.
For now this batch competes with the nvidia GTX460 and the HD6870 even with the nvidia GTX470, and might be a good pick if you prefer not to drain too much power and don't like too much noise, and they are expected to push the price of nvidia cards down even more too, which is never bad news.
Gigantic Flopp per Watt per Dollar ?

AMD must have an inside track with the HDMI folks if they are running 4.1A. My understanding is that they were only up to 1.4A. I wonder if the card is capable of not only 3D but also 5D or 6?!
