Been thinking about Zambezi.

post #1 of 6
Thread Starter 
So, i have been thinking for a while about Zambezi, and what might have happened. Seeing the "AMD taking questions" thread on [H] i decided to write my thoughts down and address AMD.

really no point to this OCN thread other than sharing my thoughts with the OCN community. Some of them might be irrational or incorrect, but i did my best to look at bulldozer in a different manner.

Here is what I posted in [H] thread:

All of the market hype, the FX moniker, and the early rumors of extremely high total performance, all seem to point to AMD having much higher initial performance results.

Question: Was some sort of critical flaw found that required AMD to hamper performance in order to ensure such flaw would not end up in the final silicon?

This seems likely to me for a couple reasons:
1. Delays, it is obvious that you were trying to fix something. Yields have not been reported to be low, so I don't think that is the issue, Global Foundries' 32nm node seems to be relatively efficient.
2. High Clocks, over high IPC. Everyone learned long ago that more instructions per clock are a better solution than more clocks. the high clocks of Zambezi seem to indicate a last ditch effort to improve performance.
3. Current issues. BSOD in certain games. Some retail CPUs showing strange issues even at stock settings (random BSOD, black screen, etc.), maybe remnants of such flaw?
4. relatively high transistor count. It seems to me that you should have been able to reduce # of transistors. Possibly indicating that some of the transistors are left overs from the original "flawed" design.
5. Not a huge advance over Thuban. With the many years AMD sank into BD, it seems that a greater improvement could have been achieved.
6. Wonky BIOSes, and some older boards that originally had support for Zambezi, not working at all. To me this shows that something changed between last year when BD rumors, and such started swirling.

Thank you for your time, and I look forward to a response.
Please, trolls, stay out....please.

[qoute]1. Delays, it is obvious that you were trying to fix something. Yields have not been reported to be low, so I don't think that is the issue, Global Foundries' 32nm node seems to be relatively efficient.[/qoute]

llano is in short supply because of global foundries 32nm not being perfect. yet.

mostly marketing fault if you ask me,and the fact they are labeling this as an 8 core cpu.
even the engineers who designed it are calling it a 4 core.

when you say it has 8 cores you would expect it to eat everything in sight, and it don't.

If they would have labeled it a 4 core this whole fiasco would be a different story.

^this

I have been saying this for so long
but since they decided to call it an 8 core, people expect it to keep up with the x6s, which is a bit ludicrous

The problem comes from the GPUs the CPUs are fine.

GPU on SOI process is kinda new i think.

The problem is that Dirk Meyer became CEO and left a crippled engineering team with not many resources. It's unfortunate, but BD is a pile of crap as a result.

I think that future revisions will bring it more on the playing field but AMD will lose a lot in the process.

On the bright side, at least AMD kept in mind that enthusiast level chips are not a major part of their market, which is why they were focusing so much on the fusion platform, since OEMs would eat it up
