Default Anand prods AMD for answers...

Interesting read.

Tight lipped AMD gives up a little more info .

-Fusion, merging cpu/gpu. I was actaully surprised how far they could take this.

Quote:
The final step in the evolution of Fusion is where the CPU and GPU are truly integrated, and the GPU is accessed by user mode instructions just like the CPU. You can expect to talk to the GPU via extensions to the x86 ISA, and the GPU will have its own register file (much like FP and integer units each have their own register files). Elements of the architecture will be shared, especially things like the cache hierarchy, which will prove useful when running applications that require both CPU and GPU power.
-Torrenza for adding in specialty accelerators.

Quote:
AMD drew the parallel to the 287/387 floating point coprocessor socket that was present on 286/386 motherboards. Only around 2 - 3% of 286 owners bought a 287 FPU, while around 10 - 20% of 386 owners bought a 387 FPU; when the 486 was designed it simply made sense to integrate the functionality of the FPU into all models because the demand from users and developers was there. Torrenza would allow the same sort of migration to occur from external socket to eventual die integration if it makes sense, for any sort of processor.
Quote:
In a sense, AMD's approach is much like that of the Cell processor, the difference being that with AMD's direction the end result would be a much more powerful sequential core combined with a true graphics core. Cell was very much ahead of its time, and by the time AMD and Intel can bring similar solutions to the market the entire industry will be far more ready for them than it was for Cell. Not to mention that treating everything as extensions to the x86 ISA makes programming far easier than with Cell.
-Why Barcelona was delayed...

The successor to the K8 was originally scrapped.
Apparently the design was massively parallel, designed for heavily multithreaded applications.
AnandTech: AMD - The Road Ahead

Could be interesting stuff if AMD can keep thier boat afloat for several more years and we see the fruition of these technologies.

Intel and AMD have been rapidly advancing our desktops and there is lots more on the horizon.

Gadzooks, I hope it doesn't take years to see some fruition! (posted this article yesterday too!)

Sorry, I missed your post on this...

They are talking about 2010 and later in the article. So with AMD delays ....~2015 ish ?
