PCI Express Riser(extenders) 3.0?

AlexCom · October 13, 2014

Hello community,

I want to build a PC, but I would need to get some Riser/Extenders for it. My concern is that, from what I`ve seen and read, that the PCI Express Risers are not 3.0.

There is a forum, if you search "pci express extension cable" (I don`t want to post links) that he tested and so no performance loss from using a cable like that. The only problem is that he used it for a 2.0 card, and I want to use it for a 3.0 card(the 980).

Do you think the cable will have any impact on the 980 performance? Thanks so much!

Have a great day,

Alex

p.s. I found these numbers, if it will help:

Base Clock Speed: PCIe 3.0 = 8.0GHz, PCIe 2.0 = 5.0GHz, PCIe 1.1 = 2.5GHz
Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/s

Shouldn't be any issues unless if you use a low quality riser cable. If there is any performance impact, I would imagine it would be minimal(latency reasons).

I could be wrong though, so wait for more input
