It's not soldered, it's _on the package_ with the SoC.
- georgeburdell 2y agoProbably on package at best
- eigenspace 2y agoIt is _not_ on die. It's soldered onto the package. There's a good reason it's soldered, i.e. the wide memory interface and huge bandwidth mean that the extra trace lengths needed for an upgradable RAM slot would screw up the memory timings too much, but there's no need to make false claims like saying it's on-die.
- sschueller 2y ago> RAM slot would screw up the memory timings Existing ones possibly but why not build something that lets you snap-in a BGA package just like we snap in CPUs on full sized PC mainboards?
- eigenspace 2y agoThe longer traces are the problem. They want these modules as physically close as possible to the CPU to make the timings work out and maintain signal integrity. It's the same reason nobody sells GPUs that have user upgradable non-soldered GDDR VRAM modules.
