Shanghai, Advanced Micro Devices' next-generation processor, is being released ahead of schedule and, the company says, minus the mistakes of its last generation, Barcelona. "Originally the plan was that Shanghai would launch in Q1 of '09 and we were able to pull that into Q4," stated Pat Patla, general manager of AMD's server and workstation chip business.The product will not only be announced in the fourth quarter but vendors will also be shipping servers in the fourth quarter that feature Shanghai.
Shanghai is a quad-core product targeted at servers and will be AMD's first 45-nanometer processor, whereas Barcelona was 65-nanometer. Typically, the smaller the geometries, the faster and more power efficient the chip. Intel has been shipping 45-nanometer processors since last year and these processors now make up most of Intel's offerings.
AMD is also boosting the size of the cache memory, which typically speeds performance, from two megabytes to six megabytes. Another speed improvement will come from increasing "instructions per clock." Shanghai will also feature HyperTransport 3, a high-speed communication link technology between silicon.
