on the 80-core Intel Terascale chip:"The chip uses a LGA package like Intel's Core 2 and Pentium 4 processors, but features 1248 pins. Of the 1248 pins on the package, 343 of them are used for signaling while the rest are predominantly power and ground."
That's 905 power and ground balls!
Remember when Trilogy went down, taking over $200 million of start-up funding with it, attempting packages with 1200 pins. How we laughed ;-)
