USB 3.0 From Older Hardware

Hello everyone,

I have a couple quick questions. Z68, X58 and chipsets before these didn't have native USB 3.0. So, how did companies advertise USB 3.0 on their boards with these chipsets? Were they really USB 3.0 capable, and did they match the USB 3.0 speeds that Intel's later chipsets offered?

Secondly, let's say I have an X58 motherboard without any advertised USB 3.0 capabilities whatsoever. Could I buy a PCI-E card with USB 3.0 inputs, place it in my PCI-E 2.0 x1 slot, and receive USB 3.0 speeds with no problem?

Thank you for your help guys.

PS: I see that PCI-E 2.0 x1 provides 500MB/s of throughput, and USB 3.0 provides 640MB/s of throughput. So, I am aware that the USB 3.0 standard is a bit faster than the PCI-E 2.0 x1 standard which is okay.

IDK, I haven't used a third party chip for USB3. I did use one for SATA 3, and it wasn't good. When I got my 840pro I wasn't paying attention to what SATA port I plugged it into and it went in a port powered by a 3rd party chip instead of the MCH/South bridge. Instead of getting the 500MB R/W speeds I was expecting, my read speeds were low 300MBs, and my writes were mid 200s? I just remember them being low. My old SATA2 drive plugged into the right port did 29xMB R/W, and my new "faster" drive couldn't even do the writes as fast as the older drive. (Both were Samsung SSDs.) I eventually figure it out and got it on the right port and can do ~525MB R/W, but the 3rd party chip was slower. I didn't leave it there to know if it was...

I don't think Intel ever really refreshed their boards like AMD. AMD, rather the manufacturers of the boards, reused that G760 chipset for a REALLY long time. The G760 didn't start with USB3, but you can find them now. Intel boards never really carried forward like this. There might be some X58 boards with USB3.0 on them, but when I had my P55 board I ended up upgrading to get the 3's. (USB, PCIe, SATA 3.)

I see that PCI-E 2.0 x1 provides 500MB/s of throughput, and USB 3.0 provides 640MB/s of throughput. So, I am aware that the USB 3.0 standard is a bit faster than the PCI-E 2.0 x1 standard which is okay.

I was going to point this out, but seeing as you know it already I'll leave it alone. I wouldn't call it "okay", but as long as you're aware of the issue.

Okay, that makes sense. One part of the question remains to be answered though. I've always wondered if these motherboards (with their third party controllers) are able to achieve full USB 3.0 speeds. Anyone have a clue there? Thanks again.

PS: I would hope most would be thankful jumping from a 60MB/s interface to a 500MB/s interface, even though it's slightly impaired. :)

So it might have been benchmarks only that I would have noticed.
