Right, so the product flyer lists LPDDR5 densities as 16 to 128 Giga
bit (or, 2 to 16 Giga
byte)
Then, when you look at the
part catalog, all of the 16 Gb/2 G
B modules are either 16 bit or 32 bit.
Since we have a fairly reasonable inference that the memory bus width of Drake will be 128 bit, that's our target to hit. From Micron's catalog, the lowest possible way to hit that with modules in Production would be a pair of 48 Gb/6 GB modules for a total of 12 GB. And if we look at parts in Sampling, it would be a pair of 32 Gb/4 GB modules (or, four 16 Gb/2 GB modules) for a total of 8 GB.
Samsung's LPDDR5 catalog seems... absurdly out of date. Still just that one 64 bit 6 GB module at 5500 MT/s. As for SK Hynix... are they seriously almost all 16 bit (save for that one... 8 bit part in the PC section?)? Or maybe I just don't know how to read SK Hynix's catalog.
Of course, I still have the thought that Drake-based Switches will outlast standard LPDDR5 (like how regular Switch outlasted standard LPDDR4). Even if Drake itself doesn't launch with 5X, then a later revised-Drake likely would. And like with the Erista->Mariko transition, I'm not expecting a change in quantity of RAM (that is, I expect it to be 'silent'). Ergo, I'm keeping tabs on 5X.
