UP1000 Performance

The UP1000 pairs a single Alpha 21264 processor with the AMD-751 System Controller, giving it cache and memory bandwidth well ahead of contemporary x86 workstation boards at launch.

Bandwidth

• L2 cache bandwidth: up to 3.2GB/s sustained
• Main memory bandwidth: up to 800MB/s (100MHz 64-bit memory bus)

Where the UP1000 excels

The 21264's deep out-of-order execution engine and the UP1000's memory subsystem make it well suited to memory-bandwidth-bound workloads: scientific/numeric computing, compilation farms, and Linux/Alpha compute-cluster nodes built around the PowerRAC Chassis 320.
