AMD Radeon HD3850 and HD3870 - AMD's salvation?AA/ AF & Image Quality Testing
We tested the scaling of the cards with AA/ AF in ET: QW and World in Conflict at 1920 x 1200. AA was set to 4X and the AF to 16X.
AA/ AF Test Results
The HD3870 performed at the same level as the HD2900XT and the HD3850 just trails very slightly behind them.
Image Quality Comparison
Crysis in-game screenshot
Crops from above
Screenshots were taken in-game and crops were taken out for comparison.
In the first 2 pictures, we can discern a slight difference with the HD3870 giving better tonal range in the glass and at the curved edge, we can see that slightly more detail is rendered on the HD3870 than the 8800GT. In the next set of pictures from Crysis, there are more details on the surface of the rocks (mid-top & lower-right) from the HD3870. In both instances, the differences are not obvious at a glance and we can't say for sure that they would be noticed in gameplay or how much of a performance impact would be caused as a result.

eg. HD3850 @ Vr-zone
idle - 126W full - 204W
HD3850 @ Overclock3D.Net
idle - 60W full - 90W
wow, that is a big gap and if overclock3D.net's numbers of true, i will go change all my gaming systems' cards right now coz they suck twice less the power.!!! [lol]
at such numbers, 60W > 90W for HD3850, it is simply bollocks coz even my 7950GT 512mb is like 90W~ on idle and 145W on full. This is totally amazing coz which even more transistors (666 million) and even smaller process of 55nm, it draws so much lesser power!. Can someone verify the numbers for HD3850? then if 3850 is so low power consumption, HD3870 shouldn't be far with the almost close chip specifications!?
1 is full system power consumption and 1 is card only. i believe the HD3850 only consume 90W on load.
