Hello

I know that you need a PCI-e x16 for connecting to my motherboard. But what is the difference between a PCI-e 2.0 x16, PCI-e 2.0 x16 and PCI-e x16?

Thanks for your help!

Bandwidth, i.e. transfer speed. For a graphics card, any one of these will do.

well the difference can be as what @Jurrunio said

"Make it future proof for some years at least, don't buy "only slightly better" stuff that gets outdated 1 year, that's throwing money away" @pipoawas

 

-Frequencies DON'T represent everything and in many cases that is true (referring to Individual CPU Clocks).

 

Mention me if you want to summon me sooner or later

Note 10, S10, Samsung becomes Apple, Zen 2, 3700X, Renegade X lol

PCIe 2.0 16x = PCIe 3.0 8x. The speed roughly doubled each generation from 4 to 8 GB/s to 15.75. It follows that PCIe 1.0 16x = PCIe 2.0 8x = PCIe 3.0 4x.

 

  • v. 1.x (2.5 GT/s):
    • 250 MB/s (×1)
    • 4 GB/s (×16)
  • v. 2.x (5 GT/s):
    • 500 MB/s (×1)
    • 8 GB/s (×16)
  • v. 3.x (8 GT/s):
    • 985 MB/s (×1)
    • 15.75 GB/s (×16)
