The decision to sell StrongARM was an absolute disaster and IMO, set Intel back by 10 years!
Dude your hindsight is severely broken.
The StrongARM MPU was a technically excellent design - it ran at 3-5 W and outperformed PowerPC and MIPS processors consuming may times that. But is was an ARM chip at a time when the market for ARM cores/ chips was for devices in the mW range. The utter vast majority of ARM customers back then wanted cheap chips and didn't care about the performance of StrongARM and just wouldn't pay for it. At most they wanted XX MIPS at $Y dollars, not XXX MIPS at $YY dollars. It was also an non-integrated MPU with no chipset when ARM customers wanted (and still do) ASICs and SoCs.
The StrongARM was a technical achievement as a CPU core but an utter business failure as a product. It was a failure under DEC. It was a failure under Intel.
Your clouded rose coloured memories of StrongARM as some huge success just waiting to happen but fumbled by Intel is just a bunch of crap. Wake up and give your head a shake.
