MIDDLE core.... this is comedy gold.Exactly, Gracemont with IPC around Sky Lake would be pretty powerfull and IMO it's not correct to be named as LITTLE core (as ARM's LITTLE cores are typically very low IPC in-order cores). It's more like MIDDLE core: saving a lot of die space and energy while delivering 80% IPC of Sunny Cove (or 60% of Golden Cove).
big and LITTLE are names based on relative die area, not performance. We already have a clear visual indicator of what that means in Lakefield, with 4-core Tremont cluster being only slightly bigger than a single Sunny Cove core.
Pretty competitive?! High core count configurations in desktops are meant for throughout. In highly multi-threaded workloads this 8+8 config will behave like a 16 core ICL at best. It would be competitive... this year.8x Golden Cove (IPC +40% over SKL) + 8x cores of SKL IPC .... this thing could be pretty competitive against Zen3 and Zen4.
The only way this addition of small cores would make real sense would be with a different ratio, so that final throughput does not dilute the big core potential, but enhances it instead. Something like 8+16 could make sense from a performance perspective.
