This is a pretty old article to be posting today.
We still have some old Power PCs in our data center. They are white elephants. I don’t see any successor being more than a niche solution, Performance difference for most applications won’t be great, and support for the architecture has been less than stellar. Whether we like it or not, Intel’s architecture has so much support and benefits from the economies of scale, that I don’t see them being challenged in any realm other than small low power devices, which is ARM’s turf.
I think it has bit of new info and Graphs... AND I think this new material has implications in a few years.
