That post from 2009 is dated and there was no proof of what the guy was saying. My personal favorite is the Belkin, because its blue, but I think either works. Why?Įither way to me both of them felt pretty much the same. I have consistently noticed that I can eliminate spiky mousegraphs right after startup by killing dwm.exe and having it restart. I think the main takeaway is that outside of keyboard interference the biggest effect on mousegraphs will be the driver/OS interaction. I will say though that when I first got the cards and used the mouse tester graphs I got insanely clean graphs but when I checked my motherboard's usb 2.0 port graph it was the same. My mousegraphs were more consistent on the USB cards than on my motherboard. If this effect was real and not placebo I would chalk it up to my mouse not being drowned out by my keyboard's polling rate. The best way to describe it was that my aim felt more consistent. I first tried the Belkin and to me I immediately felt a difference compared to my motherboard usb, it kind of felt like disabling fullscreen optimizations at first. Either way I don't think it matters and I'm not even sure if the D720101GJ is the same as the D720101 chip or what the VIA chip's model number even is.

All I was able to find regarding that is some post on a forum from 2009 saying the Renesas (NEC) D720101 is a really good chip and VIA chips come close to it. The Belkin uses a NEC D720101GJ chip and the startech uses some VIA chip. I tried doing research between the two cards and they do use different chips. I don't have a latency monitoring tool and I don't think this is really relevant but I achieve around the same scores on human benchmark and I've actually gotten my lowest scores with the PCIE card with some other tweaks I may also have just been really awesome for two days straight. I've heard some people say not to use PCIE USB cards because they add latency but I haven't noticed any. I bought them because I have one USB 3.1 hub on my motherboard and I have an audio interface and a 1000hz wooting one keyboard connected to my motherboard's USB and I wanted a separate chip for my mouse. These are the only two USB 2.0 PCIE cards I could find on amazon.
