bit_user I'd love to read a deep dive on LPDDR6 by Anton! Seems like some interesting details are buried in there. I've noted LPDDR memories becoming a lot more relevant to mainstream & server computing as the years go by, and only expect this to continue. LPDDR5 went from hardly being on my radar to being a subject of intense interest, as Apple used it in their M-series SoCs, Nvidia is using it in Grace and Vera server CPUs, and AMD's Ryzen AI Max (Strix Halo) and Nvidia's GB10/N1X are using it in client machines.

Notton DDR5: 2×32-bit= 64-bit DDR6: 4×24-bit= 96-bit So, if my math is right, dual channel (192-bit) LPDDR6 10700 = 256GBps? That would match quad channel LPDDR5 8000 Is a 192-bit LPDDR6 memory controller smaller than a 192-bit LPDDR5 controller? (Snapdragon X2 Elite has a 192-bit LPDDR5X mem controller running on 9523MT/s) How likely are we going to see LPDDR6 10700 or faster in phones, tablets, and laptops at launch? I see LPDDR6 has a slower standard at 9600, barely better than LPDDR5X, and I can only hope to never see that used in mainstream and high end products. Reply

And the star of the show, especially for the initial wave of products, is the increased power efficiency, even if you get "slow" LPDDR6-9600. Reply

Samsung already has LPDDR5X-10700 so I'd guess it will be depending on AI demand. I'd expect phones/tablets would want LPDDR6 immediately no matter what speed since many use 64-bit interfaces now so even LPDDR6-9600 would be ~35% more bandwidth than LPDDR5X-10700.

(Snapdragon X2 Elite has a 192-bit LPDDR5X mem controller running on 9523MT/s) I wouldn't really expect a whole lot to change here because the overall width is still the same. The packaging differences are likely to be the biggest thing to impact designs. We'll have to wait and see what the memory controllers for CPUs using LPDDR6 end up looking like though.

The part that should be most concerning about LPDDR6 is the potential for getting 96-bit interfaces where we would have seen 128-bit in the past (LPDDR6-10700 @ 96-bit is roughly LPDDR5X-8000 @ 128-bit).
