Has there been any benchmarking or performance tests between a PPU on PCI architecture and a PPU on PCI-Express 1x architecture?

The way I figure it, PCI Express should perform better and have less latency issues.

AFAIR, there were no public benchmarks. PCI-E version was available only for OEM (I've heard a story that in 2005-2006 PCI-E slots on some motherboards were not good enough for PPU to work properly, so PCI was choosen for retail)

Also, there was note from Ageia devs that PCI bandwidth was enough for PPU to work at full speed for up to 100+ fps.. framerate in most games was lower.

BTW, what's with similar questions, you've asking in recent months - are you preparing some enormous bad-ass article about PPU ?  Grin

Not really an article, but more like a video! Kinda like an FAQ that every noob should learn about PPU's...
But I guess I should post a article taken off the dialogue of my video.

------------------------------------------------------------------------------------------------------

Also, I contacted ASUS and asked them about the difference between PCI and PCI Express PPUs, and their response is...


I have checked with our technical support and have been informed:

From what I know the PCI Express should be faster as long as its PCI E X4 or higher if its PCI E X1 there is no real difference.

Thank you and have a great day!

Argument should be analyzed in latency terms...
