the thing is that it would need to use system ram wich you probably already know, is much slower than those on high end graphics cards today.

its no different to current IGP's in that respect, but with DDR2 and DDR3 on the horizon system bandwidth will be rather decent and combined with AMD's on board memory controller (i presume they will keep this) the latencies will be much improved

of course it wont hold a candle to a discrete solution, but i bet it'll be more than enough for casual gamers and most 3d CAD packages etc

PS PLEASE FIX THIS STIE!!!

should make the system more refined, less heat, less cost etc

By the time Fusion comes out, I expect that we will see DDR-3 or perhaps even a quad-bank memory controller on the CPU to help with this.

There are also two seperate workstation markets out there, the low end and high end. For low end workstations, then this will be a great solution that will cut costs. For the high end, if the CPU/GPU can work in Crossfire mode, then we may see the CPU/GPU plus TWO crossfire enabled graphics cards for a total of three GPUs.

I don't know because that would take them right out of the enthusiast market. Why would I upgrade my CPU everytime I wanted a new graphics card?

The path currently is: CPU -> chipset -> PCIe -> GPU

Having direct CPU/GPU communications will vastly improve any app that doesn't use large testures - the vast majority of users.

You are forgetting that unless both have access to memory through the IMC; you still have at least one of those steps. No overhead would actually be removed as you are now flooding the HT interconnect. To top that off even if they go Quad-Channel by the time they start integrating, the bandwidth is not even close to what R600 is supposed to have. DDR3 and 4 are not gonna be any kind of salvation as all these offer only efficency, they are still DDR and all we will get is a speed bump. We can pray for lower latencies.

AMD is not a big enough player to be the one who starts the move to the next flavor of RAM. Intel has to do it and increasing the memory speed has proven to have marginal effects on Core 2 products when compare to Athlon64X2s. I wouldn't expect any real rush from Intel until we get the 1333FSB and they move to a 256-bit bus. This is gonna be integrated graphics level stuff. Unless Nvidia can pump out a CPU; Intel and AMD/ATI are gonna smother them out of the integrated market for desktops and notebooks.

I don't think people yet understand the way Fusion will work in tandem with Torrenza yet...
Phil Hester explained a bit to TheReg in this interview:

Notice that Fusion will be only a part of the modular design...
Very good article...
