My vague statement was correct. I don't reveal the full details on purpose.
In about 45 days (October batch) the SP30 will be 5.5 THs
(The limiting factor will remain the PSUs. The RockerBox has much more potential for over clocking)
This will be done without mask fix, just production tuning.

jtoomim more or less got it right.

My point is that TSMC will not have 'accidentally' botched 3 separate batches of lots (August, September, October). Remember, these are the same 28nm lines that Qualcomm and Broadcomm use. The notion that it is TSMC's 'fault' is simply a convenient excuse to a design mistake. I have no doubt that TSMC is capable of a retarget of your LVT devices to meet your original performance target. However, that 10% increase you were hoping to achieve with a post engineering run retarget has disappeared. Guy, I applaud your ability to perform damage control.

jtoomim, yes my name is intentionally chosen to troll. That doesn't delegitimize my arguments. Source: I run fab sync for a major US semiconductor company. You don't have to believe me, but you can do your own research on the topic.

How do you know that they didnt get all the SP30 chips in one batch? And it just takes this long to build and ship them. Plus I think its just August and September, the October batch is purported to be back up to 5.5TH so is probably separate. Thats the way I read it anyway.

I don't think TSMC makes too many mistakes, they are not worth 106 Billion dollars for nothing.

thats the catch...it is NOT a mistake by TSMC if they are as spondoolies said 'within spec' just at the low end of that ...I"m sure if they were truely out of spec
spondoolies would have other options....such stuff is likely written by TSMC to benifit them in slippage one direction or the other on performance anyway imho.
