We've been hearing about it for awhile now, but Intel officially expanded the availability of their Nehalem-based Xeon processors today. Even though it was first introduced in the Mac Pro, the processors are now available in a wider-range of products.
These new processors support HyperThreading and a Turbo Boost feature that increases clock speeds and shuts down unused cores, allowing for a serious boost in overall performance.
The Xeon 5500 ranges in price from $188 for the 1.86GHz dual-core to $1,600 for the 3.2GHz quad-core. There is also a Xeon 3500 available in three different models that range from 2.66GHz to 3.2GHz. Pricing for these ranges from $284 to $999. These Xeon processors are now available in Dell Precision systems and the HP Z800.
