3rd party cable bandwidth tests

Using the new "Test Cable" feature in the Oculus app...

Joto 3m cable:-
  • To motherboard's USB sockets front and back (Asus Z97-A) = 1.8Gbps
  • To Inateck Superspeed PCIe card = 1.5Gbps

UGreen 5m extension + Joto 3m cable:-
  • To Motherboard's USB sockets = 1.6Gbps


note 1: I've heard someone say their 3m AmazonBasics cable gave them 2.3Gbps?
note 2: Using a 90 degree adapter to make cable go nicely down side of Quest makes no difference to speed.
note 3: What real world difference does a 3Gbps result make over say a 1.5Gbps result? Is there any difference in response or graphics quality?

    I got 1.9Gbps with my 5m usb 3rd party cable.Although I can hapyyli link with 1.2super sampling now, I'm still curious about the performance of official cables

    Sorry, what do you mean by that?

    Official Link cable on my PC gets 1.8Gbps, same with all of my higher-end USB 3.0 A-C cables but keep in mind that this bandwidth is most likely limited by Z87 chipset on my motherboard (it is dependent on how mych bandwidth is available and how it's split between ports etc etc) or by Quest itself and I use USB A to C adapter. I have no issues with Link on this configuration so we can assume that anything around this number is just fine. 

    To test the real available bandwidth the test should be performed on a current generation motherboard (preferably with Intel USB controller as they seem to be most reliable) after a reboot with only Quest plugged in to USB 3 ports. No adapters, no extenders etc. 
    The advent of computers and the subsequent accumulation of incalculable data has given rise to a new system of memory and thought, parallel to your own. Humanity has underestimated the consequences of computerization.

    I have a little data to contribute. My setup:

    • Anker PowerLine 10ft USB-C to USB 3.0
    • ASUS B450-I
    • Ryzen 5 3600

    Plugged into the red USB ports on the motherboard (USB 3.1 Gen 2 via the B450 chipset), Test Cable reports:
    Bandwidth 1.8Gbps, Connection: USB 3

    Plugged in to the blue USB ports (USB 3.1 Gen 1, I believe routed directly to the processor):
    Bandwidth: 2.3Gbps, Connection: USB 3

    Does anyone know if the Oculus Link connection will tune itself based on available bandwidth? Should I expect it to behave differently based on the extra ~500Mbps my better ports provide?

    I am also curious "What real world difference does a 3Gbps result make over say a 1.5Gbps result? Is there any difference in graphic quality?" - Note that i do not believe it would have any difference in latency based on what I've read.

    The question is, is it worth it to try to get a USB 3.1 Gen 2 working at full 10Gbps?

    Where do I find that feature?
    I don't know where to do this.

    Okay found it myself.
    You got to completely setup Link again.
    I thought you could do this later too.

    I get 1.7Gbit/s with an 8m cable:

    3m JOTO USB-A-to-C Cable

    Just got around to testing this on mine... and my results are pretty odd!

    I usually use a passive Ugreen 3 metre extension + 2 metre USB A to C giving me 5 metres total. This is connected to a USB 3.1 Gen 1. I get 1.9 Gbps on this. 

    Just for comparison I thought I would try a Cable Matters 1 metre USB C Gen 2 cable rated at 10Gbps, connected to my laptops Thunderbolt / USB C 3.1 Gen 2. The test result was also 1.9 Gbps!

    I too would be really interested if someone could post results for the official cable, as it would appear there would be no improvement if I got it? Seen as a 1 metre USB Gen 2 cable is giving me the same results as 5 metres of USB Gen 1 cable A to C cable. 

    Link has actually been performing pretty fine with the Ugreen cables I have.

    I posted earlier my results using the official Oculus Link cable.
    I am getting 2.2 Gbps.
    Have the cable plugged into my motherboard's front panel USB-C header.

    As someone wrote in another thread, that the bandwidt usage of Oculus Link is at around 180Mbit/s, I think its only important that the USB connection is at least version 3 and stable/lagfree.

    Very informative post, I'll throw mine in.  I have the recommended 10ft Anker cable with a cablecreation 16 foot extension cable.  With everything plugged in I get 1.6 gpbs and unplugging the extension cable gets 1.9.  I didn't think to try different ports, this was done with a USB 3 gen 2 port.

    Wow ok seems my cable is pretty good.

    I was worried as whilst I have 3 usb hubs in my pc all are 3.0 and I thought would struggle.

    My mobo is Gigabyte gaming x99 5P from 2015 
    Scores on the doors

    Rear motherboard usb 3. 2.3 GPS
    PCIE inateck USB3 card.  2.0GPS

    But the winner is....... (And this is a boon as it gains me an extra metre of length

    Front of case  mounted USB3 2.4 GPS

    Cable is currently oos at Amazon UK but the link is below if it comes back. Mine had the booster which is not there right now

    dethinton Usb to Usb C 5m with booster... Cost £29.59

    I bought the cable for less than $17. But I don't know how much it costs to ship to other countries.

    The exact same one 5m with booster? If so that is a great price

    on my computer, the bandwidth is 2.7-2.8Gbps
