Intel has been known to cancel chips while still at the sampling stage.

It married an E6xx Tunnel Creek Atom SoC with an Altera FPGA in the same package (different die). They had E6xxC part numbers. A quick check on Intel's website didn't find any that aren't marked EOL. The E6xx Atoms (without FPGA) are still available. Regards, Allan

A hybrid is multiple die on one substrate. This is nothing new. Intel and Altera have been proposing this for years. It is interesting that it seems to be more real now with power reduction goals in the server market as the target. We'll see. -- Rick

Ever. For just that reason.I don't, mainly because they have no idea how to build (and market) anything outside of vanilla x86. Their prices are astronomical.

Especially after this announcement http://newsroom.altera.com/press-releases/nr-intel-packaging.htm The interesting part will be how deep the integration is, its easy to get thousands of signals with very low power in 2.5/3D technologies. --Kim
