Michael Feldman The Battle for 64-bit x86 Supremacy
Post Date: April 20, 2006 @ 9:00 PM, Pacific Daylight Time
Blog: From the Editor

With the popularity of the 64-bit x86 architecture in the high performance computing market now established, a lot of us in the HPC community closely follow the rivalry between the two chip vendors, AMD and Intel. Rivalries are fun, especially when it's a "David and Goliath" story. But a lot is on the line. At a time when the demand for commodity clusters and blade servers is rapidly growing, these two companies have much to gain and just as much to lose.
