I'd love to see how those "dense" cores compare to the regular ones, because to be able to pack twice the cores at the same space (more or less), you have to give up on something.

Probably not an awful lot (for most instructions). The size of 4c isn't that different from Zen 2/3, except that it's made on a smaller node.

It just goes on to show how relatively expensive single-core performance is, in terms of transistor count vs. IPC increase. It wasn't much of a bother before with cost-effective die shrinks, but now it is.

Thanks.

The clocks appear to be lower than Zen4 EPYC, Genoa, maybe because of the higger density, so that will also play a role in the likely worse single core performance of these chips.

I doubt AMD will bring something like this to dektop CPUs, other than as an equivalent of Intel's efficient cores, but we'll see.
