The Rewards of Good Plumbing

•High Bandwidth – 2P system is designed to achieve 7 GB/s aggregate memory Read bandwidth – 4P system is designed to achieve 10 GB/s aggregate memory Read bandwidth

•Low Latency – Average 2P unloaded latency ( hit) is designed to be < 120 ns – Average 4P unloaded latency (page hit) is designed to be < 140 ns – Latency under load increases slowly due to excess Interconnect Bandwidth – Latency shrinks quickly with increasing CPU clock speed and HyperTransport™ link speed
