Features
The AOpen DX2G Plus is a dual-processor system that supports two
Intel Pentium II/III Xeon processors running at 400/450/500/550 MHz
with possible higher frequencies supported in the future. It integrates
the latest multi-processor and I/O technology in the industry to provide
the best performance for workstation users.
AOpen DX2G Plus has been designed to support Intel
latest and
highest performance processor, the Pentium II/III Xeon. Like its
predecessors, the Pentium Pro and Pentium II/III processors, the
Pentium II/III Xeon processor implements a Dynamic Execution micro-
architecture - a unique combination of multiple branch prediction, data
flow analysis, and speculative execution.
This means that the
Pentium II/III Xeon can deliver higher performance than the Pentium
processor while maintaining binary compatibility with all previous Intel
Architecture processors. Other than that, the Pentium II/III Xeon
processor is available in 512K, 1MB, and 2MB L2 cache options with
the introduction of the Slot 2 socket. Unlike Pentium II/III processors,
which access the L2 cache at half the processor core speed, the
Pentium II/III Xeon processors access the L2 cache at full processor
core speed. DX2G Plus has the design to leverage this benefit to
process workstation applications with large data sets.
