AMD's Thunderbird & yield on wafers
On the website www.hart-core.de there is very interesting news about AMD's future. Since the text from there is far too good to shorten and omit unimportant information, you can view it in full here:
WAFERs The current number of wafers is approx. 800 pieces per week and the trend is rising. More than 200 CPUs are packed on one wafer.
The T-Bird was produced in Dresden from the beginning with 1.5 GHz. Until April only in small numbers. Since May in significant numbers. The number of approx. 180,000 CPUs mentioned by Sanders for the 2nd quarter applies. These were produced in the factory until May. The production of the second half of May and June will only go on sale in the third quarter. On June 5, the T-Bird with 1.5 GHz in copper technology will be officially presented. This is already being produced near 130 nm. 180 nm is no longer an issue for Dresden. 1.5 GHz Thunderbird has already been sold to large customers. But only on the shelves from June 5th. CPUs over 1500 MHz have been and are being produced.
Work is already underway on the sledgehammer, here the 130 nm have already been undercut. So there is no doubt about commercial production by the end of the year. It is difficult to predict the quantities in which it will initially be produced. Significant numbers will be produced by the end of the year at the latest. It is less a question of ability than of economic policy considerations. The decisions about this are reconsidered almost every day. The decisive factor is the profit see Gaussian curve. Sledgehammer will in any case come onto the market in frequencies above 1500 MHz.
YIELD AT AMD COMPARED TO MOTOROLA
The systems in connection with the technology allow processors with several GHz. FAB 30 is the only company in the world that is high in copper technologyRecovery rates achieved with fast CPUs (approx. 70% at 1.5 GHz !!!!!). A little more than 200 CPUs are already packed on the wafer. Motorola, from which the patent was taken, is unable to do this itself. The G4 for Apple is produced with a yield of approx. 5% (!!!!). Motorola has therefore offered AMD to manufacture the processor in Dresden. AMD declined because the FAB will be 100% full. In case of bad times, you can still fall back on the offer. The rejection at Intel at 180 ns must be correspondingly huge at high frequencies.
Technically speaking, nothing negative is known from Germany, everything is going better than expected.
The source is 'innsbruck':
I have the information from my/our best source and have to rely on it. I have no reason to doubt the seriousness, on the contrary. Admittedly, the news, which can be described as sensational without exaggerating, also makes me hesitate, because there are no other rumors about it.
In terms of rank and name, the origin of the information would in any case be able to to judge these things absolutely correctly. So it should all be deliberate misinformation, which, I repeat myself, but I don't think so.
