'''Alpha 21464''' was an ambitious [[Alpha]] microarchitecture designed by [[Compaq]] as a successor to the {{\\|Alpha 21364}} set to be introduced in 2004. The project was cancelled in June [[2001]] when Compaq announced their commitment to Intel's {{intel|Itanium}}.

== Die ==
* 1.2 GHz - 2 GHz @ ~1.2 V
* [[0.13 µm process]]
* ~250,000,000 transistors
* ~420 mm² die size
* PGA-??? package
** ~1100 signal pins

Floorplan was done but the design never made it to fabrication.
