AMD's 'Shanghai' processor is being readied for a scheduled fourth quarter release according to AMD. Shanghai is AMD's code name for its first processor based on a 45-nm manufacturing process. Targeted at the server market, the new processor will have 4 cores and represents a critical component in AMD’s bid to regain market lost to Intel in the sever segment after the Barcelona mistakes. AMD is being adamant that the problems encountered with Barcelona will not be repeated with the new processor. Originally slated for release earlier this year, AMD pushed the date back to Q4 to ensure the product will be stable and that their OEM partners will be able to begin validation as early as possible. Shanghai is reportedly going to be around 20 percent faster than Barcelona at the same frequency. Due to the small size, power efficiency has been increased and AMD has also said the die shrink yields “a lot more frequency”. Cache size on the Shanghai CPUs has been pumped up to 6MB versus 2MB on Barcelona chips. Additionally it will execute more instructions per clock cycle and come with HyperTransport 3. AMD says Shanghai is currently in production with the first chips to be shipped to its partners very soon.
