First up: You don't really need these tools from Win8 onwards, as every driver should get automatically get installed. Just download the newest GPU driver if it's a gaming PC and you're done.
That said, this seems to be a case similar to uBlock and uBlock Origin: SDI is the "original" version and the last update was in 2017. SDI Origin was split off some time in 2016 (due to some controversy?) and is maintained to this day.
Thanks for reply
As I use modded windows without update feature i can't auto install drivers so thats why...
So both sites are fine in your opinion?
I'd lean towards the SDI Origin version since it's the only one still being maintained, which, on the surface, seems kinda important for a tool that's supposed to fetch the latest drivers.
(You'd better not ask me for my opinion on these crappy modded versions of Windows though. Using a OS that's not capable of getting updates is a mindbogglingly stupid idea.)
