Calling it an E-core makes no sense. Both cores have the same IPC, the only difference will be the maximum clocks.
AMD needs to concern themselves about the exploits found in their Zen 4 series and avoid them in Zen 5
Zen 5c is NOT an "E-cores"!!! This author is either clueless or technologically illiterate. Comparing that to Intel's Atom core crap is doing AMD a MASSIVE disservice. Zen 5c will just be Zen 5 with less L3 cache and a lower clock-speed target. That's it.
