Have to wonder about the literacy levels of some of the above readers. Lawrence Livermore identified this design as the best way forward over 3 years ago. https://www.llnl.gov/str/November05/pdfs/11_05.3.pdf Intel has been asleep at the switch as they are way behind where this design is and can't make the cut in DARPA's research projects. HEC Phase III for 2010 is AMD and IBM http://www.nitrd.gov/Pubs/2009supplement/NITRD-09Supp_FINAL-hec-rd.pdf So it looks like Charlie got the story right as usual.

the reality is that fusion has degenerated into a branding exercise - kind of sad.

amd should just bury it b/c when intel release a real fusion chip, amd would be caught with its pants down.

but what is with the anti nvidia and pro AMD news reporting from Charlie. Surely you are meant to hide the fact that you work for a company much better than this.

no Shame, although ive yet to see an Nvidia "Scandal today". Im waiting to see whats next from the guys in green. Always entertaining !

CUDA vs CAL is apples vs oranges. In one you must worry about the cache and mem, in the other you don't have to.

AFACT 4870 has better DP FP performance but GT200 has better SP FP performance.

Pick you problem and your method of solution, the choice of product will be clear.

Perhaps OpenCL will supplant CAL and CUDA at the API level. Nevertheless each company will offer products with better or worse performance.

Just like, say, POSIX threads on Intel vs AMD, OpenCL on AMD vs Nvidia will be a question of which company make better hardware for the API.

Apologies Cool Tech. You are quite right concerning OpenCl. I had in mind CAL which AMD markets as STREAM which is their version of Nvidia's CUDA.

Of course, AMD supports OpenCL as well.

Thanks.

1st things 1st, Charlie, please don't mix up product names/codes. You of all people should know its the HD4870 not the R4870 (the R belongs to the GPU code name, the RV770). And @The Sentinel, AMD didn't come up with Open CL, Apple kinda did that. But anyway, interesting article and amazing to see AMD getting so many GPUs to work together when CrossfireX is so pish, lol

SGI just isn't SGI without their pretty workstations (so I'm ignoring their IRIS/4D series).

If AMD really has SGI in mind when planning their moves, I'll get around to sending an email to AMD to start making stylish, colourful, overpriced computers with names based on hydrocarbons pretty soon

Charlie must work for AMD. This is pure marketing! Man, how I hate such articles. Why don't you improve your new site with a filter for author? Blargh.

I think the most interesting comment in this article was about the tight synchronization between the AMD CPU and the AMD GPU.

With Intel and Nvidia getting in each others space concerning both CPU's and GPU's, could this become an Archilles heel in Intel/Nvidia marchitecture especially concerning bus archicture,licensing and ultimately performance?

Also, could this comment (if it has any vailidity) portend the fact that AMD could become the next SGI...not in the sense of actually building extraordinarily pretty and overpriced graphics workstations and supercomputers...but in the sense of SGI at the time they owned MIPS and controlled and engineered both the CPU and GPU they flogged into their boxen? Also consider this....SGI came up with OpenGL. Now AMD comes up with OpenCL to "sychronize" CPU's and GPU's for higher levels of performance.

History may not repeat but AMD may be on the verge of rhyming quite a bit with the SGI of old.

Just some interesting thoughts.
