We know some of the specs, but until someone conducts a side by side, we’re not going to know.
My current understanding is:
- Q3 has a slightly higher resolution. However, the QP uses two screens instead of one, and apparently makes more use of its pixels. So it could be that the “effective” resolution of the QP is higher, and having fewer pixels easier to drive
- The Q3 gets a newer processor. Good for both locally installed and also decoding the PCVR stream as it’s supports the new AV1 video codec. It’s worth being aware that the only GPUs that can encode to AV1 are Nvidia 4K units
- The QP “probably” has smarter controllers
- The QP includes eye tracking. This is a big one that I care about, as dynamic foveated rendering is now working with DCS in the QP. So the price difference is a bit like paying for a faster GPU, as that will be the implications
- The Q3 has depth perception, which will make use in rooms safer if you’re moving about
Overall, my opinion is that the QP is better for PCVR, the Q3 for stand-alone
