Alpha 21064 was the first Alpha microarchitecture designed by DEC and introduced in 1992.
Contents
Etymology
The microarchitecture name Alpha 21064 is composed of both the ISA and the implementation. In particular, the "Alpha" refers to DEC's Alpha AXP instruction set architecture while the "21064" refers to a "21st century"-ready 64-bit "0th generation" microarchitecture.

Process Technology
- See also: 0.75 µm process
Alpha 21064 was manufactured on DEC's CMOS-4, their then-newest 0.75 µm process. The process offered three levels of aluminum interconnects and a nominal 3.3 V power supply. Note that prior to the introduction of the 21064, DEC produced early "assistance" samples for software developers which were manufactured on an older CMOS-3 process (1 µm). For that reason those chips also had reduced cache amount, in addition to no FPU support.
