Considering that it is 4 months before the announcement of Alder-Lake, I no longer expect 590 kingpin. It just doesn't make sense, + 20% IPC will be in the new architecture Golden Cove versus current Willow Cove. For now, waiting sense Z690 Kingpin.
Alder Lake rumors point at 2021 launch but I doubt it's true, they might launch it on 2022 Q1 and by Q2 availability will follow. As for the 20% IPC and all that, so far Intel didn't make any press presentation or bold moves like AMD (showing off 15% gaming boost just with a stacked SRAM cache on top of Zen 3 chiplet). And on top they are going DDR5 and PCIe 5.0 it will cause a lot of price hikes for both DDR5 and Gen 5 equipment. Then there's Raptor Lake which is going to take on AMD, but by that time Zen 3+ with V-Cache is going to run rounds at-least from the strong AMD moves it suggests. But it all boils down to platform stability and longevity.
I prefer Intel because of the stable clock speed options, stable drivers, better BIOS in the end and ability to run Win7 on most HW with ease due to monolithic design, AMD needs scheduler updates from Win10 May 2019 for CPPC and etc and constant BIOS AGESA updates. Then we have X570S Dark also incoming but how much it will help ? IF clock at 1900MHz itself is a luck, just like IMC of RKL at 3866 and up on G1. As for the rock solid clocks, AMD CPUs are better off auto.
As for Kingpin edition it won't be coming as per EVGA, maybe they are going to release that for X570S Dark ?
