Since I posted the first three, here's another of TechPowerUp articles comparing two CPUs, albeit this time it's a bit different:
RTX 4090 & 53 Games: Core i9-13900K E-Cores Enabled vs Disabled Review: https://www.techpowerup.com/review/rtx-4090-53-games-core-i9-13900k-e-cores-enabled-vs-disabled/
>>The E-cores enabled give a 0.9% increase at 1080p, 0.4% at 1440p and a 0.1% at 4K
With that said, the average results don't tell the whole story, with some titles seeing a 10% increase or decrease with the E-cores enabled, so this is one of those things that depend on a game basis, as long as you're CPU limited, of course.
It's also worth mentioning the Far Cry games tested. Despite both of them using the Dunia engine, Far Cry 5 hates the E-cores while Far Cry 6 loves them.
Please excuse my bad English.
