Dude, Intel spends something like $80B/yr on R&D. This is closer to hitting fundamental laws of physics barriers.

They killed off their P4 line and developed their mobile line for a reason.

the $80B a year in R&D is off by an order of magnitude.

Isn't an order of magnitude 10x? According to your link they spent $12.74 billion in 2016.

Not necessarily, it could be e if you're using natural logarithms. Anyway: log10(12.74) = 1.10, log10(80) = 1.90. So, it's a little less than a full order of magnitude, but pretty close.

Although not normally used for smaller amounts it can go in both directions. ~1/10th is still an accurate if archaic use of the term.

Indeed, that's more than Intel earned in total revenues in 2016...
