Current 4 year old laptop with 128GB of ECC RAM is wonderful and is used all the time with simulations, LLMs, ML modelling, and the real heavy lifter, Google Chrome.
Most modern laptops can do 64 gb of ddr4. It's expensive but doable. Like most U series CPUs are limited at 64 gb. Something with a xeon mobile chip will probably see a lot more.
yeah, i was just pointing out that we've seen desktop chips in laptops before, it's not common, but it has happened, and will likely continue to happen.
Dell 7740 Workstation laptop. Has a Xeon processor and a 16GB Quadro video card as well. 5 M2 slots so I currently have 36TB of SSD as well. 4k screen, physical privacy shutter camera, actual buttons for the trackpad. I love this thing.
