Intel scales low power I/O

In the limbo dance of the lowest mW per Gbit/second, Intel Corp. hasn't dipped as low as Rambus did earlier this year. However, it has gotten to a significant low with a chip-to-chip interconnect that scales better.

Intel presented at the VLSI Symposium this week the I/O links it uses in its Terascale research processor. The big figure of merit is 2.7 mW/Gbit/s, just slightly north of Rambus at 2.2. But the Rambus technology is fixed for use at 6 Gbits/s while the Terascale I/O can scale from 5-15 Gbits/s. For more see the EE Times story.
