I think a few cheap fixes could put them back on track.
Some no and small cost ways I think AMD could immediately disrupt and take the market.
1. Unlock clocks and multipliers on all chips, evrything should be a "Black Edition"
2. Elliminate the one pin difference between consumer chips and Opterons all are technically the same and can go in N-way servers. This would kill Intel to follow.
3. Open source your drivers and OpenCL API, sceincey types love Linux/Open Source and dictate the big cluster market. Intel's not even in the GPU compute feild and this would prevent applications from being written in Nvidia's Cg. These Massively parallel apps have lifespans of decades.
4. IBM has put 4 chips on a single package using the same Hypertransport technology as AMD. 32 cores per socket is a win in the server market where it is said the battle is won and lost in 2 sockets.
5. Push the APU's hard into consumer goods, their power/performance ratio is great when you consider their multimedia ability.
l like the author's ideas of graphics chips on G34 packages as well as APU's I also think mixing them on package and even off chip L4 caches should be considered.
