Question on Gpu's x16 and 2 x8

[MDXX]

Not sure what that exactly means, but i was wondering if it will ever be possible for 2 x16?

 

[koffeeshop77]

yes on the X99 chip set and board no problems, 2 or even 3 x 16 lanes PCI express

so is there an advantage with multiple x16 pcie? or x8 x8? Im taking is x16 can double the process that a x8 can do?

AMD have been using 2 x16 990 series boards for 5 years

It's depending on your processor as to how many lanes it can support. Their a few exceptions to this.
Most motherboards will run 2 video cards at X8 speed and if you look at the details on the motherboard some that have
2 X PIC-E 16 lanes are not true X16 lanes some will have a X16 @ 16 speed and then another X16 lane @ 4 speed.
For the advantage of running 2 cards at a true 16 speed over X8 speed their very little to 0 difference depending on how high end the video card is.
You need to get into the GTX 980ti range to fully saturate a X8 lane.
Then their another factor in the amount of bandwidth with the type of X16 lane 1.1 2.0 3.0
The AMD boards that can run 2 X 16 are limited by their 2.0 bandwidth
Some benchmarks on the different versions with different speeds.
