As per the details, it looks like Meteor Lake CPUs will be a refinement of the existing Golden Cove cores while featuring a brand new architecture for the E-Cores.
The details reveal that Intel's 14th Gen Meteor Lake CPUs will once again utilize a hybrid approach which shouldn't be a surprise by now.
The Intel 12th Gen Alder Lake CPUs feature the 0x0 "Core" also known as the Golden Cove P-Core and 0x1 "Atom" also known as the Gracemont E-Core.
Now coming to 14th Gen Meteor Lake CPUs, the Redwood Cove P-Cores are once again expected to be based on the 0x1 "Core" design which means that while there will be Core-level upgrades, the architecture will more or less remain the same
While Intel Meteor Lake CPUs utilize the brand new "Intel 4" process node, the node may not be as mature as 10ESF and we can see a clock regression that will be unable to match the high frequencies that Raptor Lake has to offer
Previous rumors had already hinted that Meteor Lake will offer single-digit IPC gains vs Raptor Lake but those will be enough to keep AMD CPUs at bay for a while until Arrow Lake comes out in 2024
