Can't believe it, did strix halo (and soon PTL 12 Xe3 core igpu whenever that becomes more widely available) which has almost no marketshare force Nvidia to release mobile dgpu with more than 8 GB vram?

Or is this a sign the bubble ending soon?

Indeed, finally?

QuoteLenovo is increasing the maximum RAM capacity of the LPCAMM2 memory to 96 GB
Good, but make it up to 128 GB RAM (Framework laptops may support up to 128 GB RAM, see their community forums posts).

5070 Laptop: 128-bit bus width.
5070 desktop: 192-bit bus width (50% higher bandwidth and 50% faster,  but many games at settings where 8 GB VRAM becomes the limit, would run much better if 12 GB VRAM was available).

128-bit/32-bit per chip = 4 GDDR7 chips, each 2 GB = 8 GB VRAM.
192-bit/32-bit per chip = 6 GDDR7 chips, each 2 GB = 12 GB VRAM.
128-bit/32-bit per chip = 4 GDDR7 chips, each 3 GB = 12 GB VRAM.

So is this finally 12 GB VRAM on a 128-bit bus (using the 3 GB GDDR7 density chips instead of the current 2 GB)? Current 12 GB VRAM gaming laptops are mostly big and heavy (and the ones who are not are even more expensive, but they can be more loud because the chassis is smaller (there's no free launch)).
