PCI lanes

[littlepigboy5]

Hello,

What are PCI, or pcie, lanes in reference to a processor.  EX.  the 4570 has max 16 pci lanes.

Thanks

thanks, i learned some stuff, lol, but i still don't understand what it means in reference to a processor...

Don't worry about it. PCI-e 2.0 x8 is more than enough for any single GPU. It's the maximum pci-e lanes a CPU can deliver.

 

Per lane, in each direction:

• v1.x: 250 MB/s (2.5 GT/s)
• v2.x: 500 MB/s (5 GT/s)
• v3.0: 985 MB/s (8 GT/s)
• v4.0: 1969 MB/s (16 GT/s)

For a 16-lane slot, in each direction:

• v1.x: 4 GB/s (40 GT/s)
• v2.x: 8 GB/s (80 GT/s)
• v3.0: 15.75 GB/s (128 GT/s)
• v4.0: 31.51 GB/s (256 GT/s)

ok so if i have an i5 4570 and 2 r9 280xs in crossfire, will i get bottlenecked?

No they will not get "bottlenecked", just make sure your board supports crossfire.

ok thanks

still don't know what max pci lanes are in a pc, help!!!

What is your question, exactly? To know what PCI lanes/PCI-E lanes are or whether your system can or will be bottlenecked by a particular setup?
