Well Mike, there are some things that all of us can guess and some things that are allready proved.As with Nehalem, I want to get views on AMD's next architecture, K10 and I ask for non-fanboyism. Some sources say it is dead, while others say it is on track for release. What I know about K10 is that it will bring Multi-Core, possibly 8-Cores or more, DDR3/DDR4, use HyperTransport 3.0 or 4.0, probably use Z-RAM or another form of Static RAM for L2 Cache and may include L3 Cache. I also heard AMD is shooting for 10GHz Operation, including additional registers, possibly SSE4, and looking for a 2007-2009 release date. What you guys think?

10GHz sounds SF to me as long as this manifacturing process is used. SOI offers less power consumation, but will not offer operating freqfency at 10GHz on 65nm or 45nm either. Adding unreasonable number of stages of the pipes is proved(P4 Netburst) as unsucessfull for performance(less instructions per clock are achieved). Today parallel processing at lower clock is forced instead of sequentional at higher, as more efficient for the overall performance race.
4 core chips are in the baseline of AMD and they are expected to apear in the 65nm SOI after H2 2K7. SOI might offer implementation of Z-RAM and that could be expected in K10 too. I guess lower freqfency than 4GHz while on 65nm SOI.
SSE4 are not only registers, instructions(not much effective on the reviewed Conroe) are also included. I guess there would be no problems for AMD to implement them in the current K8 and future K10.
No DDR3 before 2009, its too much expencive and there will be no need of that much memory bandwidth until then. I guess they will optimize the current architecture for high latency memory and will find DDR2 usefull for their chips.
I think there will be no L3 Cache. The integrated memory controler and the DDR RAM are exactly L3 for the K8. If Z-RAM technolgy succeed, with builtin memory controler there is no reason for another level of cache.
We shall see more HTT links and with better badnwidth(more bits width and on higher freq) for sure.
