A family of high-performance 64-bit RISC workstations and servers based on the new Digital Alpha AXP architecture is described. The hardware implementation uses the powerful new DECchip 21064 CPU and employs a sophisticated new system interconnect structure to achieve the necessary high bandwidth and low-latency cache, memory, and I/O buses. The memory subsystem of the high-end DEC 3000 AXP Model 500 provides a 512KB secondary cache and up to 1GB of memory. The I/O subsystem of the Model 500 has integral two-dimensional graphics, SCSI, ISDN, and six TURBOchannel expansion slots. The DEC 3000 AXP system family consists of both workstations and servers that are based on Digital’s Alpha AXP architecture.[1] The family includes the desktop (DEC 3000 AXP Model 400) and desk-side and rack-mounted (DEC 3000 AXP Model 500) systems. The available operating systems are the DEC OSF/1 AXP and the OpenVMS AXP systems. All systems use the DECchip 21064 microprocessor.[2] Table 1 gives the specifications for the three DEC 3000 AXP systems.
