So I am not one of those that screamed about the 16GB limit which was a huge number of comments here on HN. That being said I do know people in the creative industry that have Mac Pros with 1.5TB of RAM and use all of it and hit swap. For a higher end Pro laptop I would be happy at the 32GB range. However in something like an 8K display (which will be coming!) iMac I would like to see 128GB which will not fit on chip. They are going to have to go to a 2 level memory design at some point.
- sliken 6y agoMaybe, or just move the memory chips from the CPU package to the motherboard.
- myrandomcomment 6y agoOh that is very much something they could do, but given the fact that they control the OS completely it would be very interesting to keep the on chip and off chip and enable the software to support understanding which is RAM is where and allow the application developers to tweak items. For example lets say you are editing a very large 8K stream and you tell the app, hey load this video into RAM. You could put the part that is in the current edit window in the on chip RAM and feed the rest of the video into that RAM as the editor moves forward from the 2nd level RAM. There are some interesting possibilities here. Also from the ASIC yield view it allows for some interesting binning of chips. Let's say the M2 has 32MB on chip plus an off chip memory controller. They could use the ones that pass in the high end, then once that fail a memory test as 16MB on a laptop, etc. Part of keeping ASIC cost down is building the exact same thing and binning the chips in to devices based on yield.
