You can see it's old because it still has a #FrontSideBus and used a dedicaded #Chipset (or rather #PCH known as #US15W - but could also be married with other Chipsets like #nVidia#Ion - and only a single core and #HyperThreading...
@golem :blobcatgooglynotlikethis: PCIe 7.0 is 4 times faster than PCIe 5.0...
The only reason why it needs to be that fast, are actually nvme's...
How about creating a dedicated bus or still having multiple lanes for older versions, i acutally would prefer having more PCIe lanes and they also dont need to be faster than PCIe 4
@whitekiba@Jain@golem I've yet to see it's connector cuz nowhere was I able to find it...
With PCIe 4.0 that was sadly omnitted from the spec.
And yes there are valid reasons for it:
Like industrial #SBC-based systems which may even utilize passive #PCIe#backplanes that do #Bifurcation per #Chipset, omnitting the need for expensive PCIe #switches.
Kinda like the passive PCIe x16 => 4x NVMe (PCIe x4) cards.
