"Torrenza" systems will accept both multi-core, accelerators, or "Fusion" processors
AMD sheds more light on accelerated processing projects

This week at CeBIT 2007, AMD revealed more details about its "accelerated computing" platform, codenamed Torrenza. AMD's goal behind Torrenza is to create a platform where application-specific processors can interact cost effectively and offer better performance than a general purpose CPU, while remaining compatible with off the shelf platforms.

AMD guidance revealed this week that future processors will also have integrated "accelerators" embedded into them. A Torrenza system will have at least two sockets, and both will accept accelerators and accelerated CPUs.

One accelerated-processor project on AMD plate, slated for 2008 under the codename Fusion, and combines a dedicated GPU or GPU accelerator onto the same package or even the same silicon die as the main CPU. AMD has already set the ground-work for Fusion processing with its Stream Computing initiative -- utilizing ATI-based graphics adaptors for heavy number crunching. 

Other Torrenza ready projects are also coming to light.  Clearspeed announced its CSX600 math-coprocessor plug-in last year, with the stated intention of creating a socket plugin version for Torrenza.  Los Alamos National Labs is currently building the world's fastest supercomputer, Roadrunner, with Opteron and Cell processors on the Torrenza platform.

Torrenza is not just locked within the compounds of the CPU sockets. According to AMD, Torrenza systems will accept accelerators in a PCI-Express interface too, allow for multiple application specific accelerators to access system memory and processor functions directly.  Mercury systems announced a PCIe plug-in accelerator late last year.

While Torrenza is well on its way to seeing daylight, Intel is also working on its own open architecture platform. Notorious for keeping its CPU platform a closely guarded technology, Intel indicated that it was working on a competitive technology to AMD's HyperTransport, dubbed CSI, allowing direct CPU and memory access.

Intel guidance suggests the company will announce its Torrenza competitor sometime in mid-2008.

While this may be true, if it is then Intel must be well behind at the moment. In order for success as an open platform initiative, they will need to release the specs to developers well in advance (remember that AMD opened HT up to the Consortium almost 2 years prior to release, and Torrenza/Fusion is about the same). This is important because it takes a couple of years for developers to actually implement the new design...

AMD do not own Hyper-Transport, its an open standard owned by a consortium

That was my point...AMD did own HT, but they released it as an open standard to the Consortium for development. The theory being (which did work well) that by giving away the IP of HT, development for the standard would happen very quickly and in a much wider number of applications.
This is also what they have done with Torrenza...Torrenza is the coherent HT (which AMD had kept the rights to) that allows for direct connection into the cache rather than the HT controller on the CPU.

"Intel is already talking to some of the smaller companies working on accelerators about plugging into CSI and offering them a chance to play outside of the Opteron-only realm.

"There are a number of partners around CSI which we will talk about when we talk about CSI next year," Gelsinger said."

But CSI isn't an open license (unlike Torrenza and HT)...and that is a problem for developers.

It's the old story about open and closed architecture...
PCs are open architecture, and Macs are closed.
Mac makes some excellent product, but if you want to develop for Mac you must first get their approval on each product.
With a PC, you can develop whatever you want...this is FAR faster and cheaper to do, hence the difference in sales between Mac and PC.

There's also Geneseo.
