After a brief hiatus on articles, I just wrapped up a new one that discusses version 1.1 of the Quick Path Interconnect.

Here's a brief summary:

Intel’s Quick Path Interconnect (QPI) was a massive step forward over the front-side bus that was used from 1995-2008. QPI finally caught up and exceeded AMD’s HyperTransport, helping Intel retake much of the server market.

The next generation QPI 1.1 was re-architected based on trends and changes in the computer industry. QPI 1.1 is an incremental improvement at the physical and logical layer, but a substantial change in the coherency protocol. Sandy Bridge-EP will be the first product to implement QPI 1.1, later this year.

As always, comments, questions and feedback are welcome.


Regards,


David
