A life and death of Alpha Processor

Heralded as one of the best designed RISC based Processor by the best Engineers, this Alpha Processor had gone from rising to fallen from grace by Intel's dirty hands. And of course HP's Carly Fiona was one of the string puller in Alpha demise by sleeping with Intel. For all ya info, Intel and HP co-developed Itantium for high end server 64 bit processor, but the one that stood its way was Digital Alpha. Thus HP having brought out Compaq who happened to own Digital killed the whole development. Many DEC engineers joined AMD and live to fight another battle with Intel.

In facts many release generation of AMD's processors ranging from K6-2, K6-3, Athlon and eventually the existinng Opteron processor were based on its concept.

Sniped from X-bit labs

Those processors belonging to RISC are Motorola Power4, IBM's PowerPC G4, G5, UltraSparc
Processor in CISC camps are AMD ,486-100, K5, K6, K6-2, K6-3, Athlon, Duron, Sempron, Opteron, Intel, Pentiums, Pentium-Pro, Pentium II, II, IV, Pentium-M, Cryix x686....

And recently anti-trust law suit from AMD had shown they had gotten more confidence on their AMD processor and they are ready to take on Intel with volume and innovation.

Let's us join the processor crusader against Intel.

For those who want to seek more knowledge.

Right here Right now.
