More Sandy Bridge performance numbers (+Rumoured Pricing)

[informal]

There is something interesting here. For some FP test the perf delta between single-threaded to multi-threaded is about 6x-7x. Which mean that, even if we assume an equal turbo for 1 to 4 cores, HT efficiency is reaching 50-85% on a threads with an equal code. Thats very strange.

That or in single thread mode the Turbo on the old i7 is ridiculously high while in MT mode it is only one bin.With SB,the Turbo in single thread mode is maybe lower but it kicks in aggressively in MT mode providing the performance gains of 6x or 7x. Also you can see in my previous post that there are numerous 5100+ results on 32bit win7 OS for the i7 Q720. Q720 Turbo with 3-4 loaded cores is 1.73Ghz while for 1 core it's 2.8Ghz.
