4K using PCI-E 1.0 , 2.0 and 3.0 what a shocker !!!

Is the fact that AMD are not using an external bridge between the cards for the 290x contributing to higher PCI-E bandwidth being used now that they are routing the communication between the cards in crossfire across the PCI-E so therefore using them in PCI-E 3.0 mode yields better performance?

That's what I was wondering, because there isn't anything I can think of about increasing resolution that should stress the PCI-E bus more. Most of the data being sent from the CPU to the GPU should be identical whether it's 4K or 1080p.

Just run Sleeping Dogs on 4 stock Titans

4 x Titan @837/1502

3930k @4.0

4K 60htz

PCI-E 3.0 x16/x8/x8x/x8

PCI-E 2.0 x16/x8/x8x/x8

PCI-E 1.0 x16/x8/x8x/x8

Notable drop going from PCI-E 3.0 to 2.0 and huge drop going from 2.0 to 1.0


I also ran a single Titan @stock x16 with PCI-E 1.0, 2.0 and 3.0 but it is not worth posting the screenshots as the results were identical to within 1/10 of a FPS.

I don't need anything faster, my favourite games are things like Civ5 where screen size is more important.:)

Ahh cooleo, Yeah same here pretty much, Not too keen on the twitch shooters, More of an Anno player myself :)

Decided to join you in the land of 4K and got this beauty :D

4k, 1ms, 60Hz, No USB hubs, Card readers or speakers, Just the way I like it :)

Just played a bit of Batman Arkham Origins and I was quite pleased with the performance, Maxed out no AA was hovering around 50-60 which considering I'm only running 1 x 780 Ti I thought the performance was damn good :)

Very nice.:)

Don't forget a lot of the bench threads have 4K sections now and we could do with more results.:D
