Intel has shed additional light on the performance of its P-Core & E-Core hybrid design architecture featured on Alder Lake CPUs. The company initially compared the performance increase versus the Skylake architecture but now, Intel has provided us the performance per power charts pitting its P-core and E-core next to each other.

In the latest slides presented at HotChips 33, Intel shows the relative single-threaded & multi-threaded performance comparison between its P-Core (Golden Cove) and E-Core (Gracemont).
