arcticstoat writes "The wait for AMD's next-gen CPUs is finally over., as the company has now officially launched its first 45nm 'Shanghai' Opteron chips for servers and workstations. AMD's move to a 45nm process relies on immersion lithography, where a refractive fluid fills the gap between the lens and the wafer, which AMD says will result in 'dramatic performance and performance-per-watt gains.' It's also enabled AMD to increase the maximum clock speed of the Opterons from 2.3GHz with the Barcelona core to 2.7GHz with the Shanghai core.
Shanghai chips also feature more cache than their predecessors, with 6MB of Level 3 cache bumping the total up to 8MB, and the chips share the same cache architecture as Barcelona CPUs, with a shared pool of Level 3 cache and an individual allocation of Level 2 cache for each core"
