I don’t work for or at Intel.

But I would be surprised if their future direction was “simply more of the same.”

At some point, I would expect further differentiation between cores, e.g. not just E and P cores, but more letters of the alphabet, with different specializations per core type.

Maybe Arc moves into the main processor as A and/or G cores. Maybe an L and/or I core variant derived from E for even lower power when idle. Maybe yet more cores dialed in for bursty network traffic or sustained numerical workloads or equal-path crypto engines or who knows what.
