Sandy Bridge 1.6Ghz Vs Core i7 1.6Ghz Benchmark Test

A new numbers showed up on a German blog citavia showing some new Sandy Bridge numbers,

So the average performance increase with those CPUs at the same base clock, but with different Turbo Boost implementations,  is about 20%. In the diagram below we can see a significant average difference in multi-threaded benchmarks"

The Sandy Bridge CPU:
Sandy Bridge is the codename for a processor microarchitecture that is being developed by Intel and is the planned successor to Nehalem. Intel started development of Sandy Bridge in 2006. Sandy Bridge uses the 32 nmWestmere (formerly known as Nehalem-C) and applies it to the new Sandy Bridge microarchitecture.  manufacturing methods from According to statements made by Intel, Sandy Bridge is expected to be released in Q4 2010.
