Look who decided to take some time off from the PC Games section and join us...
Definitely.Fake, imo.
1. Who says they won't?
2. Who needs a paperlaunch if they don't?
Totally fake. There is no reason to do a major shift to XDR2 when theres plenty of headroom left in GDDR5.
What "plenty of headroom" do you mean?
Making memory wider is expensive. And ATI/AMD does not seem to like non-power-of-2 memory bus widths. And there is 7 GHz(data rate) GDDR5 available, but that's not much more than the 5.5 GHz(data rate) 6970 currently has.

XDR 2 wooot

Seems like it to me.Hasn't there been a trend towards increasing bandwidth efficiency faster than actual delivered bandwidth?
The nominal voltage of the 28HP process is just 0.85V (40G has 0.9V but AMD as well as nv used to "overdrive", which is said to be problematic on TSMCs 28nm gate last process).OTOH, voltage on 28nm HP is 1.05v, and HLP (if that rumor is true) 1v flat, down from the 1.2v of virtually every other process they've used up to this point (not counting the 1.3v spec they helped create and used on 55nm), close/identical to the nVIDIA standard 1v operating voltage across all those same processes (and they'll probably use again.)
Any rumours on when the next range of wonder cards are expected to arrive?
