CAMM2 roadmap was talked about in the same event as LPDDR6. LPDDR6 will be delivered to consumers primarily as 192-bit CAMM2. Lower-cost systems don't get a smaller module, they get soldered packages (and possibly less of them).
That is a bit strange. LPCAMM2 is available in both 64 bit and 128 bit versions IIRC.

Nvidia PC SoC leak dropped:


It's coming next year(2025), and will apparently have on-package LPDDR6!
Wake me up when they build a Medusa competitor.
AMD can make the same thing, replace the Z5 cluster with an X5 cluster and make it MoP and voila, Sound Wave!
Microsoft will never be Apple, neither will NV no matter how hard they copy Steve Jobs.

I wonder if Apple will downgrade the memory buses of their SoCs when they adopt LPDDR6. M3 Pro getting gutted to 192 bit might be the first step...

(Speculation)

M5 : 96-bit LPDDR6
M5 Pro : 192-bit LPDDR6
M5 Max : 384-bit LPDDR6

it makes sense, because LPDDR6 will adopt 24-bit memory channels, which is a 50% increase from LPDDR5/5X. This means the traditional 128/256/512 bit memory buses are not possible.

Wow I can't wait to hear the complaining, and the Apple blamefest, if this happens and the majority of the PC market goes with soldered DRAM.

Especially if Apple reverses course on the Pro/Max/Ultra lines and use LPCAMM there. I'm somewhat skeptical they will for laptops because making the whole bottom panel removable (let alone adding a door) to Macbook Pro would mess up the clean lines. But for Studio and Pro, sure.

If they have smaller LPCAMM modules today for LPDDR5X, why would they limit it to 192 bits wide for LPDDR6?

And is LPCAMM2 upward compatible with LPDDR6? I assumed with extra control signals it would need to be revved, but I guess they must have had a few unassigned pins they could use for stuff like ALERT?

There is no way Apple is adopting LPCAMM.

They have decided to solder both the RAM and storage, in everything from the Macbook Air to the Mac Pro. There's no going back.

Upselling RAM/Storage for absurd prices is Apple's way of making profit. If the user could upgrade the RAM/Storage, then nobody is going to pay the absurd amounts Apple charges for RAM/Storage.

The starting 10667 Mbps speed for LPDDR6 is cool, becuase it gives us some nice bandwidth figures:

LPDDR6-10667
96-bit = 128 GB/s
192-bit = 256 GB/s
384-bit = 512 GB/s

The 10667 is the bitrate at each pin.

Earlier generations didn't have metadata mixed with the data.

Well, that could explain why LPDDR6 bumps up the channel width by 50%.

Without that channel width bump, LPDDR6-10667 Mbps (minus the metadata), it is actually slower than Micron/Hynix's LPDDR5T-9600.

It's a Tegra (bad) with an off the shelf CPU (bad) and rest not relevant.
I wonder does this mean AMD's Sound Wave won't happen at all, or will be repurposed as the steam-deck's APU was?

We know that:
  • Sound Wave was only designed for MS as an alternative to this nvidias chip
  • This "leak" (straight from the horse's mouth) tells us beyond any reasonable doubt that MS will use nvidia
So what purpose would it serve?

MSFT wants to push WoA with multiple vendors.

Only issue for the Pro/Ultra/Ultra is the modules are huge, my understanding is currently doing a 512-bit bus with LPCAMM would be a mess in the laptop. But maybe with round LPCAMM for LPDDR6 this isn’t as much a problem.

Why are guys entertaining the idea of Apple using LPCAMM? Surely, it's not happening.

If EU regulation comes to Apple doors - yes, it CAN happen, and if they will focus user upgradeability - it will happen.

While Apple has not stated this directly, there have been indications they could pull out of the EU market if the EU puts too much pressure on them.

At any rate, I will be glad when desktop jumps on the CAMM bandwagon.
