Faster CPU with LPDDR3 or Slower CPU with LPDDR4X?

Compromise question. I need a laptop while we move as my desktop rig won't travel well. Two otherwise-identical Win10 machines I'm looking at are available with EITHER:

 

10th-Gen i7-10710U (6 cores, 12MB cache, 4.7GHz max clock), 16GB of 2133MHz LPDDR3 and Intel UHD graphics

OR

10th-Gen i7-1065G7 (4 cores, 8MB cache, 3.9 GHz max clock), 16GB of 3733MHz LPDDR4X, and Intel Iris graphics.

 

I've read that LR and PS like CPU speed, cache and cores (to a point) more than memory speed. Will the faster CPU with 2 more cores and a 50%-larger cache, but slower, lower-bandwidth LPDDR3 be better or worse for PS, LR and occasional Premier edits/renders than the faster, higher-bandwidth LPDDR4X on a slower processor with fewer cores, a smaller cache and Iris graphics? 

 

Many thanks for your insight. One of those combinations will jump out at some of you as a no-brainer. Any other obvious factors I'm overlooking? SSD in each case, of course. Both CPUs are 12W TDP.

Memory speed is relatively unimportant to LR performance.
