question about AMD and PCIe 3.0 ?

[BIGNEWY]

Hi all,

 

Ive been looking around trying to price up a new pc build, does anyone know if AMD supports PCIe 3.0 or is it just an Intel thing ?

 

thanks for looking

PCIe 3 is an industry-wide standard.

 

Just look at the motherboard in question and see what it has. Depending on component it may or may not support it - this goes for AMD as well as Intel, VIA, IBM etcetera.

Thanks for the reply EthereaIN,

 

I was under the impression AMD did not support PCIe 3.0, I can only find a few AMD motherboards with PCIe 3.0 but they are using a stand alone chip to handle the extra bandwidth.

 

Also some web info suggest that PCIe 3.0 is not that important when looking for a new Motherboard.

 

its a confusing world out there on the web :)

PCIe 3.0 is to new for the hardware [some games] to use fully..

 

I think I said that right..

The 7990 only uses 62% of Available PCIe 3.0 16 Lane Slot..

 

The Titan uses around 52%, The 690 around 59%.

 

Just Sayin'.

 

 

i think a 7970 Ghz Edition will never Max out a PCIe 2.0 16 Lane Slot.

900 Series Chipsets were done and Being Fab'd already before PCIe3.0 was finalized

 

AMD's next Chipset will have 3.0 Support, the 7800/7900 Series AMD GPUs have PCIe3.0 Controllers.

 

However, Like I said, the 7970 By itself will not max out a PCIe 2.0 16-Lane Slot, so PCIe 3.0 16 Lane Slots are pretty much pointless.

 

The only GPU I've seen to go above 50% of a PCIe 3.0 x16 Slot, were the 7990s, 690s and Titan, WHEN THEY ARE IN PCIe3.0 Mode, when they are in PCIe2.0 Mode you lose like 2% performance, that's it.

Thanks for the info guys
