A Semi-accurate Look into Fermi

[Eastcoasthandle]

lol wow, the web is a fickle place. all those that despise Charlie D suddenly approve of him because his article supports their loyalties... in reality, his writing style hasn't changed one iota. the only thing that's changed is the calender and it's getting closer to when nvidia finally has working silicon, so that is what he is reporting. so it turns out it should have been nv those people should have been dispising all along. oh the irony!

given patterns like this, it seems there must be some real inherent social dangers to the internet.

And I thought I was the only one who noticed this. They seem to love Charlie now. After reading the article (not just what was quoted in the OP which omitted a lot) Charlie hasn't deviated at all. For example:

If you assume that A3 will fix all the problems, and that it will be the launch stepping, there are two main things that will affect the launch date from there. First are the risk wafers. If they are still valid, then that will probably shave a few weeks off the time until production silicon will start rolling off the lines. Lets call the savings about four weeks, or six weeks versus ten weeks if the risk wafers had to be scrapped.

The next variable is based on how sure Nvidia is that A3 worked out the way it wanted that to. If it is 100% sure that A3 is the one it will launch, Nvidia could have started running wafers at the same time it put the A3 hot lots in.

Since the problems that we hear about on A2 silicon are related to bin splits and clock speed problems, and general yield in the good versus bad chip sense, this might be a fairly large risk for Nvidia to take. Given that, six weeks out from Dec 1 if it put A3 in on day one and the risk wafers are still valid, ten weeks if not. If it waits, that is +6 and +10 weeks from Jan 1 or so.

Last we have the time it takes to make boards, put them in boxes, and ship them. A good guesstimate is two weeks for the initial boards, including air freighting them from Taiwan or mainland China to get them ready for the big party. This assumes the prep work has been done, and the PCBs are simply waiting for chips.

The first take home message is that Nvidia can likely show hot lot early A3 silicon at CES, but we doubt the company will launch it there. Tegra 2 is probably a better fit for that, but don't be shocked if it has A3 silicon floating here and there.

If all goes well, risk wafers valid, A3 production went in on Dec 1, and all the stars align, you are looking at Dec 1 +6 weeks +2 weeks, or about Feb 1 for real availability. More realistically, if it waits until the A3 hot lots get back, that would be Jan 1 plus eight weeks, or March 1 for a hard launch. Basically, the best case is Feb 1 for a real launch.

The negative view is that the risk wafers are invalid, and Nvidia waits for A3 to come back before it puts in production wafers. That would be the outer bound, Jan 1 +10 +2 weeks, or April 1, Q2 of 2010. If you have a really negative outlook and think there will be an A4 stepping, add about four to six weeks for every stepping past A3. That is really unlikely to happen - really, really unlikely.
