AMD Phil Hester, AMD's chief technology officer, stopped by the Hot Chips conference here at Stanford University on Tuesday to talk a little more about Fusion, AMD's plan to integrate a graphics processor and PC processor onto the same chip. By the time the chip is ready around 2009, Hester thinks the growing explosion of video and 3D graphics on PCs these days will require an affordable chip that still delivers great graphics performance.

chipsets -- the gpu is only half the battle!

dear amd, please integrate the entire chipset, not just a gpu. hopefully you already know this, and have some idea how useless chipsets are.

the conventional role of chipsets has been to connect memory and i/o devices to the cpu. amd has already moved memory controllers onto the cpu core, and this news item specifies that the highest bandwidth output device in the computer is going to be integrated too. remaining roles for a chipset could be a usb controller, sound card, ethernet card, pcie bus, or any other i/o device commonly found in PC systems. chipsets also contain the bios bootcode for the system.

now that the two highest performance subsystems have been integrated onto the cpu (memory & graphics), there is no need to continue offering a seperate i/o chip: just integrate the remaining peripherials on die. x86 remains the only market where chipsets are used, and its a heapload of complexity that serves no advantage, particularly for anyone in embedded space (where complexity comes at tangible cost of boardspace).

so, put the sound controller, ethernet controller, pcie host, all those little things, into the cpu. its 2007 and the x86 is the only architecture still hampered by being a processor that is completely useless without a high bandwidth connection to a chipset whose seeming only purpose is to boot the cpu and host its peripherials. get rid of this relic, put everything on die, and bring x86 into embedded space. every other embedded cpu has a fairly complete i/o spec built in, and x86 is stuck in the past with massively over-complex system over-engineering.

(i've also heard rumors that fusion is not going to be x86, but no matter the architecture, get rid of the chipset)
