Google has made some interesting choices for the Pixel 8 Pro.

Tensor G3 will switch to the more recent ARMv9 cores from 2022. This should offer parity between the G3 and other leading chipsets such as Qualcomm's SnapDragon 8 Gen 1 series.
SD8 Gen 3 due out in a few months, and Tensor 3 just matches the 2 year old Snapdragon, which wasn't know for good efficiency or battery life, it was the Gen 2 that has massive improvements to battery, and then the upcoming Gen 3 due out soon is supposed to still be very efficient, but offer a big hike in GPU performance 50%+ better than Gen 2.
My prediction for the 8 Pro, yes the flatter screen will be nice, but it's not iPhone 14 Pro or Nothing Phone 2 FLAT, it will still have a slight curve at the edge. But still a flatter display over the current curved screen will be welcomed.
The screen is supposed to also be brighter, which is good
Other than that, the Tensor 3 is another minor improvement over the Tensor 2, nothing radical, and not even close to the SD8 Gen 2. So I would expect performance and battery life to maybe be a little better than the current 7 Pro but not much
