Intel "Arrow Lake-S" to See a Rearrangement of P-cores and E-cores Along the Ringbus

[erek]

"Every P-core would be no more than one ring-stop away from an E-core cluster, which should benefit migration of threads between the two core types. Thread Director prefers E-cores, and when a workload overwhelms an E-core, it is graduated to a P-core. This E-core to P-core migration should see reduced latencies under the new arrangement."

Pair this with the upcoming removal of the “Hyper Threading” and changing how jobs are dispatched as a whole this could have some interesting benefits.
Primary game threads on P with secondaries on nearby E could relive pressure on Cache and such.
Looks fun all the same, can’t wait to see it in action.

You have the wrong picture, erek. You want this one, which is the new (rumored) layout, as if it were applied to RPL.

What's interesting is that this will use Intel's 20A process as well as TSMC's 3nm for the GPU, plus a tile based design is going to make this one very interesting CPU.
