Eliminating Architectural Bottlenecks
Legacy x86 Architecture
• 20-year old front-side bus architecture
• CPUs, Memory, I/O all share a bus
• Major bottleneck to performance
• Faster CPUs or more cores ≠ performance
AMD64 Technology with
Direct Connect Architecture
• Industry-standard AMD64 technology
• AMD’s revolutionary Direct Connect
Architecture eliminates FSB bottleneck
• HyperTransport™ Technology interconnect
for high bandwidth and low latency
