> The reason it has been stuck to 16GB is precisely because Intel mobile chips did not support any more than that up until a year ago. So rather than blaming Apple, it should rather be placed on intel.

That is not true, example CPU I had in my old laptop: https://ark.intel.com/content/www/pl/pl/ark/products/78939/i...

Supports 32GB RAM, released in 2014.

The reason some older laptops didn't have more RAM was twofold: 1. Either the BIOS wasn't written with such support 2. There were no RAM sticks big enough (no 16GB in a single SO-DIMM) so you could have 2x16 - but there are currently since a year or two, SO-DIMMs with 32GB RAM, so you could easily reach 64MB in a laptop.

GP means LPDDR3 support which capped out at 16gb on intel, which was because their 10nm lines with LPDDR4 were delayed years. It was always possible to use regular DDR but for laptops the low power variant is important.

... and yet they use DDR4 (not LP) on at least one of their laptop lines.

Yes they do on the 16”, after years of complaints from users who didn’t understand the constraint, and which they added the maximum allowable battery size to (~100wH), and it still only lasts 3-4h in moderate use.

They switched it on the 2018 15-inch and it didn't change the battery life at all.

Seemingly out of necessity?

GP didn't write about LPDDR3, just a vague statement that intel cpus didn't support > 16GB RAM, which I proved was wrong.
