CPU and GPU all in one to deliver the best performance-per-watt-per-dollar

AMD today during its analyst’s day conference call unveiled more details of its next-generation Fusion CPU and GPU hybrid. Early mentions of Fusion first appeared shortly after AMD’s acquisition of ATI Technologies was completed a few months ago. AMD is expected to debut its first Fusion processor in the late 2008 to early 2009 timeframe.

AMD claims: “Fusion-based processors will be designed to provide step-function increases in performance-per-watt-per-dollar over today’s CPU-only architectures, and provide the best customer experience in a world increasingly reliant upon 3D graphics, digital media and high performance computing.”

The GPU and CPU appear to be separate cores on a single die according to early diagrams of AMD’s Fusion architecture. CPU functionality will have access to its own cache while GPU functionality will have access to its own buffers. Joining together the CPU and GPU is a crossbar and integrated memory controller. Everything is connected via HyperTransport links. From there the Fusion processor will have direct access to system memory that appears to be shared between the CPU and GPU. It doesn’t appear the graphics functionality will have its own frame buffer.

While Fusion is a hybrid CPU and GPU architecture, AMD will continue to produce discrete graphics solutions. AMD still believes there’s a need for discrete graphics cards for high end users and physics processing.

Also mentioned during the conference call is AMD’s new branding scheme regarding ATI products. Under the new branding scheme, chipsets for Intel processors and graphics cards will continue on with the ATI brand name. ATI designed chipsets designed for AMD platforms will be branded under AMD as previously reported.

Actaully it meant for both. It will used more in business class desktops then euthunistic class mother boards. But my guess AMD will only make 1 Chipset for bothe business and games. Then you can decide if you want 4 core CPU or a 2 core CPU/GPU. Really by then physics might be big and even gamers might choose the 2 core CPU/GPU over a 4 core system. Amd will al ready have DDR3 in systems by 2008 so maybe the system memery will be fast eonough for GPU (not gaming speed but physics or desktop 3d)

no, they won't make a graphics core a generic x86 one, this will kill the idea. forget about switching between 2/4 cores - but it doesn't matter anyway - just run specialized physics or whatever code on integrated gpu like it's done in G80 and get your 10x/100x speedup on that. with dicrete graphics card you can do this - run AI on a half of the gpu shaders and physics on the other half while cpu sits there doing nothing :)
