This is combining a GPU onto the CPU die. The CPU can already run graphical data (or any other kind.) However it is generalized for it all and not very optimized for anything (comparing to things like sound processors, physics processors, or graphics processors which are optimized solely for their respective tasks.) Laurabee is simply a CPU-like system optimized for graphics, ray tracing specifically.

There are several reasons why a GPU on die with the CPU makes sense: memory access, GPU computing, power savings, and economics.

Memory Access - Integrated GPUs (iGPU)share system memory since it doesn't have its own dedicated VRAM. The way it works now is that the GPU is on the NB. In order for the iGPU to use the memory that is connected off the CPU, the iGPU sends the request out via the Hypertransport bus to the CPU's memory controller (MCT) and then to the memory before making its way back to the iGPU. Because the physical distance is so far apart between the iGPU and the RAM, the latency is greatly increased. Putting the two side by side, the latencies will be greatly decreased. Latencies should further be decreased since the two will be communicating natively with each other without the use of the Hypertransport bus.

GPU computing - Because GPUs are so powerful these days, combining the two to maximize the advantages of both will yield a result that is greater that simply the sum of the two parts. The first generation will simply be a separate GPU right next to a separate CPU. In time, more and more of the GPU will be intertwined with the CPU so that the two will no longer be distinguishable from each other - true "fusion."

Power savings - Before the 780G chipset, all iGPUs are traditionally fabbed on manufacturing processes that are at least one generation behind CPUs so the iGPUs consumed more power. Also, in AMD systems, since the iGPU needs to use the memory that is attached to the CPU, memory access by the iGPU needed to "wake up" the CPU to its full power state, even if the CPU is idling. This is solved with the new generation of AMD CPUs where the memory controller has its own power plane but the Hypertransport bus still consumes power, especially under high memory access.

Economics - By placing the two on a single packaging, the NB will be rendered completely obsolete. As a result of this, mobo manufacturers will no longer need to worry about the VRMs, PWMs, tracing, heatsinks, etc. associated with having a NB. AMD is also guaranteed to make more money since they will be pushing the platform of the CPU and GPU and the mobo makers will probably end up getting more of a price break.

Will be great for laptops if heat is not a problem with them. Bet these chips will be little space heaters lol.

Those people that use PC for games make like 10%. Games are not everything!!!!!!!

I read an article from Amd last year about the fusion project. What I gathered from it was it is focused on workstations and buisiness computers that size, power consumtion, and over all cost, makes a big difference. These chips will be a big improvement in all of these areas. They also speculated on useing it in a crossfire setup simular to the hybrid systems but the fusion cores would act as a brain for the GPU's. In essence telling which card to render what and compiling it all together on the fusion core it self. Think of your manager he comes in tells the team what each member needs to get done then takes all your work puts it together and gets the credit, which would give a substancial boost in scaleability when xfireing multiple GPUs. I don't know if they are still going this route I have not heard anything else about it and like I said this article was when they first started talking about fusion cores over a year and a half ago.

When AMD have it this hard I have to be really angry or stupid to bash the CPU manufactor that took me into PC-gaming. Hope the sell like butter cuz we want more hardcore CPU's from AMD.

maybe they can make ram slot to dedicated to the internal GPU? I dunno why I always have this thing about memory for gpu, always wish I can add whatever much as I wish like system RAM
