AMD hypes Linux goers about Opteron

Quote

Using a technology AMD calls x86-64, the company added new instructions to the current x86 processor architecture that extended the chip to 64 bits of data. The move to 64 bits enhances performance for servers by allowing them to support much larger amounts of memory than current AMD Athlon chips, which manage only 32 bits of data. Thanks to the extra memory, a server can decrease access times for data by minimizing its need to seek out that data on a hard drive.
