Why isn't AMD Promoting its 90nm CPUs More?!?

"With all due respect, we think AMD has very good reason for staying quiet now and is quite wise in doing so, for now.
This article will explain why, again, with some new supporting information, and in the end, some new developments that ought to eventually be very good news for AMD fans and give a good indicator as to when the best time to go to Hammer ought to be for most. "

A good read on IBM/AMD 90nm SOI CPUsAMD has managed to convince an obviously not-too-inquisitive media that it has succeeded where Intel hasn't and can make cool-running 90nm chips.
What has escaped the media's attention is that AMD is making relatively slow, cool-running 90nm chips.
What happens when you try to run them faster?

Please tell me that your assorted errors in grammar and spelling were intentional.
They have it backwards. AMD isn't making slow chips. I believe that they knew full well of the voltage (and hence speed) limitations of SIO. It is Intel that has screwed the pooch. By making the P4 pipelines so long they enabled/required (depends on point of view) very high clock speeds. AMD chose a design that would yield similar performance at lower speeds an dmuch lower power consumptions.
If AMD is being too quiet I'll bet that it has to do with production capacity, yields, or some other such issues.
Intel vs AMD issues aside.....
I for one was wondering exactly why AMD could make 2.4ghz (& limited numbers of 2.6ghz) Athlon 64s but hadn't released any 90nm CPU at these speeds.
If you read all the way through it looks like 1H 2005 we'll see 2.4ghz & higher Athlon 64s with SSE3 instructions added
You can prioduce more 90nm CPUs than you can 130nm CPUs on a given Wafer Size. If AMD could make then run at that speed they would, to do otherwise indicates problems.
Remember it took AMD a whole year to move from the original 800mhz sample Clawhammer CPUs to the 1.4-1.8ghz Opteron range they introduced in Apr 2003
Another thought is that they may only have one fab that can produce .09 cpus?
I think their FX testing is rigouros (spelling?) as a lot of the 3500 winchesters i see do well over 2.6 ghz on the standard heatsink. I'm guessing the next cpu will be a 3700 Winchester at 2.4 very soon. The fact that half multipliers isn't supported is giving AMD a headache i think. A lot more cpu's could have been released.
And it did take 18 months for AMD to go from 1.8ghz to 2.6ghz with its 130nm process. It will probably take a similar amount of time to perfect the 90nm process too.
Next year will be exciting for Athlon 64 CPUs
