This article contains information about scheduled or expected future computer chips.
It may contain preliminary or speculative information, and may not reflect the final specification of the product.

AMD Fusion is the codename for a future next-generation microprocessor design and the product of the merger between AMD and ATI, combining general processor execution as well as 3D geometry processing and other functions of today's GPUs into a single package. AMD's merger with ATI closed on October 25, 2006. This technology is expected to debut in the timeframe of late 2008 or early 2009; as a successor of the latest microarchitecture.

Regarding future AMD microarchitectures beyond the introduction of the latest microarchitecture at mid-2007 and a refresh of the microarchitecture in late 2007 and early 2008; AMD executive VP Henri Richard's June 2006 interview with DigiTimes hints at the future processor development beyond that of the well documented one:

Q: What is your broad perspective on the development of AMD processor technology over the next three to four years?

A: Well, as Dirk Meyer commented at our analysts meeting, we're not standing still. We've talked about the refresh of the current K8 architecture that will come in '07, with significant improvements in many different areas of the processor, including integer performance, floating point performance, memory bandwidth, interconnections and so on. You know that platform still has a lot of legs under it, but of course we're not standing still, and there's a next-generation core that's being worked on. I can't give you more details right now, but I think that what's important is that we're establishing clearly that this is a two-horse race. And as you would expect in a race, sometimes, when one horse is a little bit in front of the other, it reverses the situation. But what's important is that it is a race.

In an interview with Exec VP of AMD, Mario Rivas, CRN.com claims that: "With its Fusion program, AMD hopes to deliver multicore products using different kinds of processing blocks. A GPU, for example, will excel in multiple parallel computational tasks, while the CPU will take on heavy number-crunching duties. The Fusion-based processors, with the CPU and GPU integrated in a single architecture, should make the life of software programmers and application developers much easier, Rivas added." [1] This could signal that the design of Fusion has been going on for sometime. According to the article, further details will surface in December of 2006.

Preliminary Information

  • Fusion is a heterogeneous multicore microprocessor[2] combining a general purpose processing core and a basic graphics core into one processor package
  • Expected to come in 2008 to replace the AMD Turion 64 mobile processor for laptops
  • Four platforms focus on the four different aspects of usage[3]
    • General Purpose
    • Data Centric
    • Graphics Centric
    • Media Centric
  • Different clocks for the graphics core and the central processing core [4]
  • Benefitted from the modular design initiative by AMD, graphics core can be change without much re-design of the whole core [5]
  • According to Dave Orton, Fusion will have 10% more pins than a "normal CPU" [6] but failed to reveal what CPU he mentioned was a "normal CPU".
  • An unnamed AMD Vice President recently expressed that Fusion can be implemented into mobile phones, UMPC and small multimedia devices [7]
  • A new set of instructions and development libraries for Fusion were being developed [8]
  • The codenamed Bulldozer processor cores will be incorporated with GPU cores to form the first Fusion processors, codenamed the Falcon family, focusing on desktop market with TDP of 10 to 100 Watts. For the other product implementing the codenamed Bobcat focusing on low power consumption (1 to 10 Watts TDP) computations for handheld devices such as UMPC.
  • The Fusion series processor will see new modular design methodology named "M-SPACE", such that design of future multi-core processors will have a wider range of combination, as well as gaining enhanced flexibility, thus to minimize the architectural changes for different combinations of components.
  • Fusion products will include at least 16 PCI Express (presumably version 2.0) lanes.

Speed increase

There is to be an expected speed increase with the Fusion. Because the GPU and CPU will be on the same die, information transfer between the CPU and GPU/GPU memory will significantly increase since there will be no need for the information to travel on a bus as there is with current motherboards (resulting in the GPU able to shunt far more data than on the PCI Express bus, due to significantly larger amounts of bandwidth available). A motherboard is the central or primary circuit board making up a complex electronic system, such as a modern computer. ...
