Default AMD Radeon HD 8990 dual-GPU specs leak out

Well it was bound to happen sooner or later...

looks cool! Keep in mind that a dual-core card will only use half of what it is labeled at, EX a 6 GB card doesn't really have more usable than a current 7970 or 7950 because each GPU is limited to 3 GB.

And we would just have to worry about price

Fake. Look at the original source:



8770 at 896 SP=14 CU=56 TMUs, not 48
1500MHz memory on a 384bit interface yields 288GB/s, not 322GB/s.
8950 should have 4.84 TFLOPs according to specs, not 4.5
The XTX moniker usually designates an ultra high end single-GPU SKU like X1900XTX with slightly higher clocks. To my knowledge no dual-GPU SKU has ever received a special moniker.
8750 and 8770@250W max???
Both tables contradict themselves. 3.4 or 3.2 bn tranistors for 8800? 2.0 or 2.1 bn for 8700? 1GB or 2GB for 8770? 2.8 or 3.94 TFLOPs for 8870? etc etc.

Additionally many key values are taken from 3DCenter speculation half a year ago. Plagiarism and fantasy at their finest.

yeah, this sounds like a fantasy

we never got an official 7990, and the rumor of the 8900 is an even bigger chip on the same 28nm, which can only mean hotter/more power...I can't imagine even the most miraculous architectural improvements would allow them to put two into a single card if they never felt comfortable enough to produce a 7990

Heck, even the FirePro S10000 that uses two Tahiti GPUs uses the cut down LE and not the full XT...and its still 375W TDP...

I hope the specs for the 8900 GPU are close if not spot on, however I seriously doubt we'll see two of them in single card, certainly not fully enabled.
