AMD has released more details about the processor chip 12 core Magny-Cours or AMD Opteron 6000, which will be applied to gaming servers. Later in the year 2010, with 45nm SOI process, Magny-Cours chip will use the same micro architecture processor server quad-core Shanghai, so if there is an additional per-thread performance, the chip will be designed to support a better system.Basic idea of the chip Opteron Magny-Cours 6000 began from 6-core processor 2 Istanbul, combined to reduce power, then pressed into a single multichip module that can be condensed into a single socket. By using multichip module, AMD will be able to make 12 cores in the temperature and the same power to Istanbul. While used initially, AMD make dual-core multichip for the first, the Smithfield-based Pentium 4, which mimic the first Intel quad-core. However, the existence of a clear Nehalem chip per-core performance, AMD seems to have improved the credibility of the server processor chip with multichip strategy is adopted.
Multichip AMD has a more complex architecture than Intel, because each chip has a memory controller Istanbul dual-channel DDR3 own, plus 4 Hyper Transport link. This is caused, the user can not encourage each chip with full interconnection bandwidth through a single socket, so AMD had to reduce some of the link. Multichip designs Magny-Cours has a 4 port and 4 port HT DDR3 memory. Even so, 12 cores from AMD Opteron 6000 is still a lot if placed in a socket and probably will happen paralysis bandwidth. To help drive the transistors in the bus bandwidth, making the type of cache AMD HT Assist, just like the one in Istanbul.
