quote: Fusion: The CPU world as we know it is heading for change. AMD with the acquisition of ATI in their fusion concept can drop 2 R600 cores, and 2 Barcelona+ cores onto 1 die, and drop two of these into a much maligned Quad FX mainboard (yes, or pretty much any Dual or Quad socket Opteron mainboard as well).Wonder why 45nm and fusion is so special for them?

quote: Fusion = Torrenza on-die. It's basically including the graphics coprocessor into the die itself.
quote: A chip die with 2 R600 cores and 2 Barcelona cores would be the largest cpu ever. The R600 is rumored to be well above 600 million transistors, so 2 of the is over 1.2 billion. The current dual core K8 chips are roughly 227 million transistors, so even if we say the Barcelona has the same number of trasistors as K8 (which it won't) this brings us to a total of 1.4 billion transistors. Conroe at 65nm (with 4MB of cache) is roughly 300 million transistors and 143mm^2. At 45nm you could fit roughly 600 million transistors in that same 143mm^2. This means that the chip you described would be more than double that size at around 300mm^2.
