The Sony G XQD is a very fast card, but a touch slower than the Lexar 2933x with both read, write and in-camera performance.
These Sony XQD cards are slightly larger than SD memory cards, but much smaller than CFast memory cards. Although CFast cards are slightly faster, XQD cards can still outperform what any camera is capable of. These are basically mini SSD drives.

Real World Memory Card Performance
The Sony G XQD card has some great real world performance, although when tested in the Nikon D850, I don’t see any speed advantage over using UHS-II memory cards since UHS-II cards perform a lot faster in other cameras like the Sony A9 that can write to UHS-II cards at a speed of 146.88 MB/s. Looking at the Nikon D850 and the cards only are written to the XQD cards at a speed of 113.84 MB/s. For some reason the Nikon D850 doesn’t have great UHS-II memory card performance, but if this were to be improved we could should be able to see UHS-II speeds of around 150MB/s.
It’s likely the Nikon D850 is using XQD cards simply for their reliability and breakage resistance.
