AMD's Director of Product Marketing for Server/Workstation John Fruehe admitted today that 12-core Opteron chips have already begun shipping, as reported last week. What the company is calling its most advanced x86 processor, codenamed Magny-Cours, is officially named the Opteron 6100 Series and production has started weeks ago at a factory in Germany. Fruehe goes on to say that OEM partners began receiving production chips in February, though exactly who received the chips is not yet being publicly revealed.
