Intel acquired StrongARM from Digital (DEC) in 1997 (after DEC sued Intel over Pentium). Intel turned StrongARM into Xscale. You are correct that Intel sold part of their Xscale business to Marvell, but they also kept the Xscale storage processors. http://edc.intel.com/Platforms/Previous/Processors/IOP/ All the generations of XScale are 32-bit ARMv5TE processors (ARMv5TE ISA without the FP instructions) manufactured with a 0.18 µm or 0.13 µm (as in IXP43x parts) process. I think the reason for Intel selling off most of the Xscale business to Marvell is that Marvell has an architecture license, and ARM, Ltd probably didn't want to sell one to Intel. Apple helped develop ARM, so it likely has a less expensive license than anyone else. Given that Intel knows how to get an ARM5 into 0.13, getting a theoretic A6 into its 0.22 process is likely straight-forward. |

Even the 3GS is a cortex A8 which is built on a 45nm core.
From what you're sayin intel is very far behind in ARM technology.
