    Bulldozer will be the first “clean break” we have seen from AMD’s K8 core. Bulldozer is easily the most promising architecture we have seen from AMD since its Opteron launch in April of 2003.

    The first Fusion processors will be split between the "Bulldozer" CPU core, which is specifically designed for desktops, servers and HPCs (high performance computers), and the "Bobcat" CPU core specifically designed for mobile and low power devices. It will be the first complete architecture change since K8 was introduced with the Athlon 64. This means it won't be socket compatible but it will still use features common like HyperTransport and eventually DDR3 memory.

    Specifically, the "Bulldozer" CPU cores will not feature VLIW (very long instruction words) but still OoO (out of order) execution on a superscalar architecture. It will have a far deeper pipeline than Barcelona and Shanghai while still maintaining a high IPC (instructions per clock cycle) and increased workflow capability. New x86 instructions will be included and specifically targeted at HPC and media processing, and an extended SIMD capability will be targeted specifically at media data. Finally, also included are four HT3.0 links, DDR3 memory with G3 memory extender (G3MX), PCI-Express 2.0 and IOMMU.

    Úgy néz ki hogy dolgoznak rendesen a fiúk.
