AMD Opteron Processors w/ Bulldozer Architecture Launching September 26th
PCMag.com claims that AMD will be releasing the companies first Opteron server processors featuring the new ‘Bulldozer’ core architecture will take place on September 26, 2011. It will be on this date that the Opteron 4200 series, codenamed Valencia, and the Opteron 6200 series, codenamed Interlagos, will hit the market. Those waiting on the desktop variant known as Zambezi-FX will be happy to know that things are still on track for a September October (Q3 2011) launch for those parts as well. This confirms the rumor about Zambezi-FX processors launching on September 19th, 2011.
At AMD’s analyst day last November, the company described its next-generation Bulldozer core as the biggest change in x86 servers in a decade. The new processor cores offer up to 50 percent more throughput as AMD’s current 12-core Opterons while sitting in the same power envelope, according to AMD, while a redesigned memory controller serves up a 30 percent boost to memory performance and a flexible 256-bit floating point unit. AMD’s 32-nanometer Bulldozer two-core modules share some components across the two cores, namely fetch and decode units, L2 memory cache, and a floating point scheduler, but each core in a module has its own L1 cache and integer unit scheduler. Each core has just one thread but by sharing some resources with another core, those threads come less expensively than they would if each Bulldozer core was an entirely stand-alone unit.
