The AMD Opteron™ processor for servers and workstations is based on AMD’s 64-bit architecture, which represents the landmark introduction of the industry’s first x86-64 technology. The AMD Opteron processor is designed to run existing 32-bit applications with unsurpassed performance, and will offer customers a seamless transition to 64-bit technology as they require. This next-generation processor provides a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership and development.


The AMD Opteron Processor features:

• Exceptional 32-bit performance to run existing applications at next-generation processor speeds
• 64-bit extensions for applications that demand 64-bit support, the AMD Opteron processor delivers flexibility and performance
• The option to migrate only those applications that require 64-bit support while running existing 32-bit x86 applications natively on the same system
• Support of up to three (3) HyperTransport links, providing up to 19.2GB/s peak bandwidth per processor
• 64-bit wide key data and address paths that incorporate a 48-bit virtual address space and a 40-bit physical address space
• ECC (Error Correcting Code) protection for L1 cache data, L2 cache data and tags, and DRAM with hardware scrubbing of all ECC protected arrays
• .13 micron SOI (Silicon on Insulator) process technology for lower thermal output levels and improved frequency scaling
• Support for all instructions necessary to be fully compatible with SSE2 technology
• Two (2) additional pipeline stages (compared to AMD’s seventh generation architecture) for increased performance and frequency scalability
• Higher IPC (Instructions per Clock) achieved through additional key features, such as larger TLBs (Translation Look-aside Buffers), flush filters, and enhanced branch prediction algorithms
