Phenom B3 cant even beat old Q6600, expect more from Nehalem.
we all know what current intel processors can do and how it kicks the butts of current AMD processors, including the new Phenoms who despite TLB bug fix in the B3 revision, the supposedly better hypertransport 3.0, the integrated memory controller advantage of AMD, etc... Phenom 9850 still cannot beat the good old Q6600 kentsfield in overall performance. and to remind you guys, the Q6600 is not even a Nehalem.
see Phenom, part deux: Ars reviews AMD's B3 silicon revision
now that Nehalem is coming, expect greater performance since Nehalems will come with 3-channel integrated memory controller and a hypertansport-like bus which is the QuickPath Interconnect, etc.
