Bright Side of News has some more information about AMD's upcoming eight-core Valencia and sixteen-core Interlagos processors, you can read it over here.
Enter Interlagos and Valencia; AMD's first processors based on the revolutionary [for AMD, of course] CPU architecture. According to released information, a 170% increase in number of cores [from 6 to 16] should result in 400% performance increase in Floating-Point calculations on a clock-per-clock basis. Add variant clocks to that and we have a receipt for a hard battle in server/workstation segment. Valencia's theoretical numbers should show similar jumps, but overall performance will differ due to difference in memory controller: Valencia comes with a dual-channel, 144-bit memory controller while Interlagos features a quad-channel, 288-bit memory controller.
