Petz,

The FSB bandwidth is already 3.2 GHz. Intel doesn't need to increase it. They could introduce 128bit (2 channels) to memory, use PC-1600 and match the FSB bandwidth this way.

Intel's pins needle us theinquirer.net

In which Mike Magee has his take on the extra pins, or rather a reader's plausible countertake, which I think is the same as Scumbria's from long ago. 55 extra pins wouldn't be enough for another 64 bits on the bus, anyway. Foster has 603 pins, presumably to make up for all the pins Intel is saving by using Rambus.

To which a lovely reader was fast off the mark with the following at 08.47 BST:
"I'm assuming your smart comments are due to the fact that you live in the U.K. and
therefore grew up with the unrest in Ireland and violent football games.

"However, I would like to point out that the increase in pin count is really nothing more
than adding PWR/GND pins. Electrical switching can cause significant noise which
effects signal stability and is reduced by having an extremely stable power/ground plane.

"As frequencies rise, this is more and more necessary, otherwise both clock speed will be
limited or random failures may occur. The reason why this is not done from the start is
that this adds to the cost of the system. However, only having a one year lifetime for the
423-pin socket is a bit odd. (Our italics)

"I can almost guarantee you that the Hammer family will move to a different socket for
essentially the same reason. Or, look at RealWorldTech's Silicon Insider on IBM's Power4
processor, where the core is so huge that it has no less than 5,000 pins, with over half
being nothing but power and ground pins."

John,

Double wide PC100 performance may even be bearable.

That would offer lower bandwidth than PC2100, and be considerably more expensive. It might offer lower latency because of more open banks.
