Honestly the HD 8850 is weak. For $220 other than 40W
less power consumption, the HD7870GHz edition is about the same price.
The HD8870 is probably going to get a VRAM bottleneck since it's clocked to 6GHz effective. The HD8950 seems to have better memory clocks, maybe due to a different memory supplier but for 10% gains over a HD7970 everyone would just grab the HD7970 unless the HD8950 was cheaper. It is also the same chip as 8870 it seems.
The TDP drop better not be from cutting compute on all the midrange cards, even if HD7790 is reassuring us this won't happen.

They will probably play the NVIDIA strategy of putting out a big hole in their lineup and when people stop paying for the TITAN/GTX 680 introduce the bad dies as GTX 780 or GTX 670/GTX 660 Ti.
They probably learned from sales figures that majority went for HD7950s over HD7970s so this gen they're doing away with that and going what amounts to a HD7970--> HD7870XT-->HD7870-->HD7850 kind of thing at launch.

This is my expectations
HD 8970 - 2304 sp, 3 geometry engines, 8 ACE 2.0, 48 ROP, 6 GB GDDR5, 384 bit memory (1100 / 7000) for USD 600. +35% perf wrt HD 7970 Ghz
HD 8950 - 2048 sp, 3 geometry engines, 8 ACE 2.0, 48 ROP, 3 GB GDDR5, 384 bit memory (1000 / 6000) for USD 400 - 450. +15% wrt HD 7970 Ghz
HD 8870 - 1792 sp, 2 geometry engines, 8 ACE 2.0, 32 ROP, 2 GB GDDR5, 256 bit memory (1200 / 7000) for USD 300. HD 7970 Ghz perf (+45% wrt HD 7870)
HD 8850 - 1536 sp, 2 geometry engines, 8 ACE 2.0, 32 ROP, 2 GB GDDR5, 256 bit memory (1100 / 6000) for USD 230. GTX 670 perf (+30% wrt HD 7870)
HD 8830 - 1280 sp, 2 geometry engines, 8 ACE 2.0, 32 ROP, 2 GB GDDR5, 256 bit memory (1000 / 6000) for USD 200. GTX 660 Ti / HD 7950(800 Mhz perf) (+15% wrt HD 7870)
Put it in a chart graphic with an OCN logo and we can drive traffic to OCN! These rumor mills like chiphell and wccftech have been wrong before, so at least raghu78's prediction would be more useful

Its amazing how people still don't get this. AMD is a business just like Nvidia. They both want money. They don't care about the consumer as long as their products are being bought. People think AMD/Nvidia are their best friends. Its laughable.
I agree, both are bad but NVIDIA is worse. Look how bad compute is crippled on Kepler and their stranglehold on their partners with respect to OCing and voltage control.
AMD and NVIDIA are like LG and Samsung for LCDs: they have a cartel on pricing.
160W TDP though instead of 185W. and unlike HD7870Xt which only has 10% more FP32 performance this has 40% more
The GTX 670 is 170W , GTX 680 is 195W
If they just used the same as HD7790 FP32 performance per watt the specs make sense (about 20GFlops/W)Edited by AlphaC - 5/28/13 at 7:41pm
