UPDATED ON: 2022-05-17 Added latest AIDA64 FPU benchmark to show supremacy over 12900K
UPDATED ON: 2022-05-04 This is the most powerful configuration, which runs Windows 7 without any issues or side effects. Threadripper 3XXX is possible, but micro freezes and stuttering are present, so it is not a viable option for smooth experience.

Internet is swarming with amateurish articles about “incompatibility”
of modern hardware with legacy Windows 7 operating system.
In fact, it is 100% proven misconception.

Who said that it is not modern enough?
░ COMMENTS ON RIG INTERNALS
Rig is 100% working. I can do what ever i want. Blender, Affinity Photo, Renoise, Ableton, Vegas, whatever.
Previously to Ryzen 5000 build i have 1st-gen Threadripper 1950x on x399 chipset. And I have to admit that consumer x570 despite the fact that it is not supported it works much better than x399 which actually was supported and marked as for professionals.
What a mad world we live in. But, yeah, this is normal.
The most complex part is USB chipset drivers and support of modern ssd drives. I’m talking about NVME ones. Windows 7 have essential support of such type of drives, but it adds with a patch, which was conveniently [intentionally] removed from sucky ms hotfix site.
By default Windows 7 installer can’t detect USB mouse and keyboard on modern chipsets like x570.
PS/2 connector is not present at modern motherboards, so…… we got to find another way.
░ SOLVING ARTIFICIAL DIFFICULTIES
There are two solutions which can solve our installation problem.
If provided links do not work then your ISP is blocking “unwanted” resources. Use VPN or Tor Browser to undo their pathetic restrictions. Usually custom builds already come with ripped microsoft shit like “inability” to work under Windows 7 with modern CPUs. Thanks to Zeffy we have Wufuc utility which lifts these moron limitations.
I also advice you to check out SYSTEM HACKS section of my blog.
As for video adapters, current high end generation 6900XT even has official drivers from AMD . Final version was released on 2021/6/21. So green light here.

In future posts will consider to provide more detailed, comprehensive comparisons. So, stay tuned.
High-end systems can work under Windows 7 without any restrictions. It’s all about shitty politics and cheap marketing. Period.
PS: And yeah, intel looks like shit in terms of FPU, multithreaded and rendering performances.
