The K10 part codenamed Barcelona is up and running. It's not ready for launch, but AMD has already got parts ready and working.
We don't have many numbers but at least in specfp_rate2000 Barcelona ends up a bit less than 50 percent faster than Intel quad core codenamed Kentsfield.
We are quite sure that this is the best score but it definitely sounds impressive. AMD chaps are very confident that K10 marchitecture and native Quad core is the way to go and Intel will probably have to pay the price for duct taping its chips. AMD will come to collect in second half of 2007.
