AMD HD 8970/9970 specs just for fun.

[Fastx]

I was wondering if anyone wants to predict what they think the specs might be on the *HD 8970/9970 AMD card before the launch announcement.


Die-chip 28mn (sp/mm) size?
SP's?
TMU's?
ROP's?
Core clock?
Memory clock?
Memory size?
MI?
TDP?
Performance increase percent #'s over the HD 7970GE?
Price?

Also does anyone think AMD might bring out two different 28nm chip sizes per a larger size/one (440mm or +) specifically for the *HD 8970/9970?

*HD 8970 = HD 9970

Thought these were leaked months ago

Just posing this for fun to see who comes the closest on the above listed spec questions and performance once the official specs are released and we see the performance per review bm's on the 8970/9970 vs. the HD 7970GE.

Ill go with exactly the leaked specs.

2304 stream processors
144 TMUs
48 ROPs
1100 MHz
6 GB of GDDR5
384-bit memory interface at an effective speed 7.0 GHZ
35 % faster than 7970
TDP of 250 W

1,024,000 stream processors at 2000 GHz.

The Bonnaire core actually makes a good starting point. At the expense of trivializing the GPU manufacturing process, it would logically make sense to double and treble the resources that Bonnaire has. It seems to be a very balanced core and keeps TDP low.

3xBonnaire = 8970/9970
SPs: 2688
TMUs: 168
Bus width: 384
TDP: 255-265W
ROPs: 48
Die: 450-480mm
Transistors: 5.5-6 billion

Again at the expense of trivializing, looking at the 77xx to 78xx series which of like doubling of everything, did not see doubling of either the die size or transistor count hence the estimated figures above.

Similarly, this leaves room for a 2304SP part to compete against the Gtx 780.

It also means that if they double bonnaire for 88xx/98xx series they will have smaller die for the 1792 SP part = cheaper to manufacture and competing with 760/670
