Well, it "looks" nice, but I'm still extremely skeptical of them reaching even 55xx levels of performance with the 65xx nomenclature. Just look at 68xx compared to 58xx. And this being on the CPU die with the bandwidth contraints to memory that it implies just makes me even more skeptical.
IMO, at least 56xx performance is what I'd need before I consider it adequate for gaming. Still it might be good for light gaming. More importantly for me is that it will be fantastic for HTPC duties if its real world power consumption is significantly lower than an equivalent CPU + 54xx or 55xx with at least the same audio and video playback capabilities.

The naming of HD6800 tells nothing of the rest
HD5550 = 320 SP / 16 TU / 8/32 ROP @ 550MHz / 800-900MHz DDR3 or 900-1000MHz GDDR5 @ 128bit
HD5570 = 400 SP / 20 TU / 8/32 ROP @ 650MHz / 800-900MHz DDR3 or 900-1000MHz GDDR5 @ 128bit
HD5670 = 400 SP / 20 TU / 8/32 ROP @ 775MHz / 1000MHz GDDR5 @ 128bit
HD6670 = 480 SP / 24 TU / 8/32 ROP @ 800MHz / 1000MHz GDDR5 @ 128bit
