I used to have a, I believe, three processor Alpha computer when I worked at Microsoft. I had a MIPs, PPC and X86 based computers as well and all were top end and the Alpha always seemed to outpace them all. I was sad when it was discontinued.
- thesz 6y agoFrom what I know (I used to be software engineer in the hardware design team) Alpha designers used to use domino logic [1]. It allowed for some quite beefy circuits expressed in smaller space, because domino logic dominantly used nFET transistors which are usually smaller than pFET. Typical k-input Logical AND-NOT uses k pFET and k nFET transistors, the domino logic uses one pFET and k nFET for similar purposes. The paper about domino logic synthesis [2] hints at what Apple uses for their CPU cores.
