Geekbench shows the Pixel 3 Lite XL may be the first with, of RAM

The Pixel 3 Lite XL has been spotted in Geekbench and it's powered by a Snapdragon 710. That
 would make it slightly faster than the Pixel 3 Lite, which was seen with Snapdragon 670.
It gets better – the benchmark reports 6GB of RAM. That’s more than any Pixel to date. The Pixel 3 and 3 XL have 4GB and (according to leaks) the Pixel 3 Lite will also have 4GB.
The Snapdragon 710 and 670 are both 10nm chips and have nearly identical hardware. Both have two A75-derived cores (at 2.2GHz and 2.0GHz, respectively) and six A55-derived cores (both at 1.7GHz). The extra 2 gigs of RAM might make more of a difference in day to day performance.
Earlier info on the Lite models shows that the Pixel 3 Lite XL will have a 6” screen (LCD) with 1080p+ resolution. And look at the renders below, they are missing something big.
The Google Pixel 3 Lite has been spotted in the wild at least three times, but the XL version has been elusive so far.
