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.
