I think if a X9000 don't in a intel iMac working, what would be if put something like T9500, T9300 or T8300 in iMac? Look like they don't have unlocked multipliers... Bus/core rate for T9500 is 13, for T9300 is 12,5 and for T8300 have 12.
Thermal specification and thermal design power are same as in T7700.
Maybe can anyone test?
