Actually $9 more to go from 2GB to 4GB, just for the RAM chip itself. See my reply above. 32GB is impossible at present. No-one makes a 256 gigabit (32x8) chip

32GB is impossible at present. No-one makes a 256 gigabit (32x8) chip to fit in the same footprint, so then you have to do a new board design to support multiple chips, which might not be doable in the board's current footprint.
Micron do a 192 gigabit (=24GB) chip but it's LPDDR5, rather than LPDDR4x, which I imagine the RPi 5's SoC can't drive.
- matt-p 2y agoNo, I can see in 10K volume it's a bit over $3, and RPI will be paying less for sure. Even if we look at farnell for a qty of 50.. https://uk.farnell.com/micron/mt53e512m32d1zw-046-wt-b/dram-512m-x-32bit-25-to-85deg/dp/3954472 https://uk.farnell.com/micron/mt53e512m32d1zw-046-wt-b/dram-... 50 - £9.29 EX VAT https://uk.farnell.com/micron/mt53e1g32d2fw-046-wt-a/dram-1g-x-32bit-25-to-85deg-c/dp/3652197 https://uk.farnell.com/micron/mt53e1g32d2fw-046-wt-a/dram-1g... 50 - £12.04 EX VAT Those are public prices (not even account price) for buying only 50, and there's ~$3 difference even there.
