So I thought. But then what’s up with the differences in performance?
16% more GPU performance for Panthor
That difference largely comes from the compositor and desktop environment (including e.g. X11 vs. Wayland). The tests themselves are too simple to put any significant load on that beastly GPU, so what you see is, basically, how quickly the application can swap buffers… Don’t look at those scores, as you won’t see that kind of difference in real life.
What you should look at is the score in the terrain test — that’s the only one that represents real performance.

It seems that the PVT technology is patented by Rockchip and here are the patents. Their patents orignate from China so i wouldnt have so much confidence at least the idea is unique, but in any ways whoever though about using Ring Ocsillators’ drawback as advantage to monitor chip health against production or temperature or votlage, should be smart enough. Here are the patents and the one i auto translated pvt_Rockchip_patents.zip (744.3 KB)
