Don’t forget 32—>64GB max RAM, definitely worth $400 for those who need it or are planning on keeping it for a long time and want to future-proof a bit.Blame Intel for the Wi-Fi AX thing, and the screen is technically better. The 15 inch has 220 PPI, this 16 inch has 226 PPI. Yes, its a small difference, but its a difference, so you can't say they didn't improve the display. Also, going to 3 better microphones, 6 speakers instead of 2, 11 hours of battery instead of 10, 2600 DDR4 RAM instead of 2400, up to 8TB instead of 4, and adding an escape key and better keyboard. Literally the only thing that didn't change is the CPU and the webcam.
Also worth mentioning is the GPU upgrade. Vega 20 performance—previously available only on the $2,799 model as a $350 upgrade, so 3,149 at a minimum—is now included on the $2,399 base model. GPU upgrades (5500M 4GB and 8GB) are also available options for the base model, you don’t need to move up to the $2,799 tier to get them now.
