This is the second instance of this question being raised; the other instance being on the KnC thread. So that makes two times that well known, highly experienced - maybe, some might even say, leading edge - chip design firms have gone with "massive" chip topologies.
As I said before, I like it - I think it would be cool to see Bitcoin mining start to drive advances in IC tech, as people try to extract more performance and efficiency. With bitcoin, the improvements just from better ICs immediately give you an edge, while with other hardware you have all the other limiting factors: drives, memory, bandwith, etc plus the fact that software might not be able to take advantage of your hardware easily. With bitcoin, simply having a faster chip gives you an advantage.
It's definitely cool to see bitcoin ICs being designed in an ultra-high end way, comparable to top end CPUs and GPUs (or network switch chips I'd bet), instead tiny 110 and 130nm chips, equivalent to the kind of chips people use for low end ICs in toys and support chips like USB controllers, etc.
All I'm sayin' here - because I don't know the answers - is maybe we should recall what many experts said about IBM a few decades back. I'm paraphrasing here, but:
What I don't get is why anyone so experienced would build such as small and underpowered computer and suggest it has business uses. With small computers you cannot mount and read tapes or card decks, and have to rely on memory discs, which are small, slow, and very expensive. I can only really think of not having to cool the iron core with water as an advantage, but then your processor is so slow and can't process even a moderate sized COBOL program.
See what I'm sayin'?
Still though, don't forget the Carl Sagen quote, though:
"But the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright Brothers. But they also laughed at Bozo the Clown."All great successes have their doubters, but there are far more failures then successes.
Still there's every reason to think
these guys will be able to deliver.
