Its not coming out Q1 2010 on a 28nm process... a lot of that info looks like someones wishful thinking to me... I'd be unsuprised if they did manage to get it onto a 28nm process towards the middle of the last half of the year tho - even Q2 wouldn't be entirely outside of possibility tho very unlikely. Q1 2011 would seem more likely by a long shot than Q1 2010 and they need it on 28nm really to get a decent performance gain - 1920 shader on 40nm wouldn't be much faster than the current 5870.
Q2 would be entirely outside the possible, likewise 1920 shaders would perform the same at the same clocks on 40nm as 28nm, and theres plenty of clock headroom left on 40nm.
But the whole thing is bogus, just down the awful fake maths used.
Did no one notice, 5870 to 5970, 2,154 transistors to 4,308, double.
5890 to 5990, supposedly 2540 to 4760 transistors...........
whoops, when someones faking a table, get the basic maths right. Other than that, its all bull, this is stemming back to the twaddle that the 4870 had a spare/redundant shader clusters, which it didn't. Someone simply completely misread the picture of the core, it didn't have any spare, neither will the 5870 architecture. Bonus clocks and better quality pcb/power circuitry, cooling and you'll have your 5890 with higher clocks.
This generation from AMD will not have a 384mbit bus, nor 1920 shaders. Its 1600 shaders, 256mbit bus and thats it. The 68XX's might finally move up to a 384mbit bus, but then, we're starting to look at a new architecture for early next year(possibly very late this year if Global get it right, TSMC will NOT get 28nm out this year, well, at launchable yields on large cores, limited run 4770 type core at poor yields as as tester, maybe).
Wishful thinking basically, what we'll probably see closer/before/just after Fermi actually gets released is a 5890 with circa 20% more performance than a 5870 for around the same price, with a 5870 dropping to maybe the £250 mark, the 5850/5830 dropping by 5-10% and probably the introduction of a 5950, but the most important card will be the 5970 actually being forced to its rrp of £420, which will likely make a mockery of the entire Fermi lineup.
