AMD seeks redemption with ‘Shanghai’ chip

Let bygones be bygones. That's what Advanced Micro Devices is hoping for with the roll-out of its first 45-nanometer processor Thursday. The No. 2 PC processor supplier will make the case that Shanghai is not Barcelona. The latter chip–AMD's first quad-core processor–was rolled out in September 2007 to great fanfare but then faced prolonged delays. This gave Intel an opportunity to regain ground it had lost to AMD in the server chip market. Shanghai is not a new architecture but essentially a refresh of AMD's Barcelona Opteron chip. AMD claims Shanghai is 35 percent faster than Barcelona. The chip is being built on 45-nanometer process technology, while Barcelona was a 65-nanometer part. Typically, the smaller the geometries, the faster and more power efficient the processor
