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.

i second that - as long as fusion on-die gpu is generic enough, has no fixed pipeline, is DX10 only and can be employed for vector/parallel calculation code like G80 today - this is some unduckingbelievable speedup for the cpus. the physics simulation on integrated gpu shaders? it's just the beginning. now we have two/four genric cpu cores - but then with 45nm we'll have some superduper version of cell with not just puny 7 SPEs - that's gonna be some serious stuff - folding at home and rc5 will suddenly have nothing to do after a couple of years - coz the speedup in vector fp code will be not even _orders_ of magnitude.

right, so this will be specialized cores scheme, not a bunch of generic cores like now, but this is actually good - see how nicely stuff is done today when we have specialized gpus and generic cpus working together? this cell idea is ripe and ready, sony is outdated now by the graphics with G80, but with fusion sony's cell will be total nothing - 7 puny SPEs versus ATI integrated DX10 massively parallel shader engine? ha ha ha ha [demonic laughter here]
