My thinking about all performance questions:
1) older x6 Thuban with die size 370+mm could be better than FX 8150 with 315mm size?
2)older x6 Thuban with 3.3 GHz/3.7 GHz (half of threads) could be better than FX 8150 with 3.6 GHz/4.2 GHz?
3)If yes, why is not 32nm Phenom II x8 with die size simillary as FX? It would been finally better (and at 32nm maybe could Thuban higher stock clocks)!

No, it make no senses..
