What's the betting line on memory in the 27-inch model no longer being upgradeable by the user?

What's the betting line on memory in the 27-inch model no longer being upgradeable by the user?
- ksec 6y agoOh No!. You are right. But then how can you use upgradeable memory with Apple SoC? Falling back to DDR4 ? Doesn't seems like possible due to bandwidth requirement. Let's just hope they start with 16GB on Desktop.
- wmf 6y agoMaybe M1X will be the first to DDR5. Nah, just kidding, time to solder everything.
- mhh__ 6y agoPOWER is shipping with it this year at some point
- Hamuko 6y agoI imagine upgradable memory will be a requirement with the Mac Pro (if it survives the transition).
- mariodiana 6y agoI haven't been paying attention to the engineering particulars; I just know that the two laptops and the Mac mini released have no user upgradable RAM. Are you saying there is something about these "M" chips that suggests there will be no upgradable RAM? I'm missing something.
- ksec 6y agoIt was written in the assumption that Desktop M chip will have much bigger GPU and hence higher Memory bandwidth requirement. They could use 8 Channel DDR4 which gives them 200GB/s. That is roughly 3 times the memory bandwidth of current mobile M chip. Or DDR5 and pushes it to 400GB/s. Although DDR5 is barely out. Also worth noting, if they use 8 Channel DDR configuration, the minimal amount of RAM shipping would be 64GB. None of the above hypothesis seems very Apple to me.
