AMD's 64-Bit Opteron Powers Appro 1122H

The time for 64-bit processing has arrived. With the introduction of AMD's 64-bit processor, customers now have a platform that addresses their current and future computing needs.

The AMD 64 architecture extends the x86 instruction set architecture to support 64-bit processing, offering full compatibility with both 32-bit and 64-bit systems. It delivers 64-bit capability while remaining compatible with the vast quantity of 32-bit x86 software. In fact, 32-bit and 64-bit applications can run side-by-side atop a 64-bit operating system. Even on a 32-bit OS, AMD 64 enhances legacy applications' performance because of its wider data paths. There's no instruction translation layer or compatibility mode to limit the performance of 32-bit applications.

Using the correct benchmark for testing an AMD 64 system is very important; choosing the wrong one could produce misleading results. Despite the fact that the Athlon 64 runs both 32-bit and 64-bit code, mixing and matching 64-bit and 32-bit code in the same executable to run a benchmark may not be the best solution. Careful code optimization most likely would be required to get big leaps in performance, not just doing a recompile in 64 bits.

Engineers recently evaluated a high performing Opteron server built on AMD's 64-bit architecture from Appro, a system builder located in Milpitas, California.
The system incorporates MSI's K8D Master Series MS-9131 motherboard, a highly scalable mainboard for AMD's 8131 chipset. Running Microsoft Windows Server 2003, the system features two AMD Opteron 248 64-bit processors running at 2.20GHz with HyperTransport technology. The server includes 2Gbytes of 333MHz DDRSDRAM, an 80Gbyte Seagate Barracuda ATA/133 hot-pluggable hard drive, one 64-bit 100/133MHz PCI-X slot and dual Gigabit ports.
