The 1080ti is out there for almost 10 years now. It has 11GB of VRAM. A 5090 has 32GB.
SOCs with unified memory have shifted this a bit forward, but they're also expensive as shit.
10TB ram in a consumer device is simply not happening in the next 10 years.
Half a year ago you could get a AI max 395+ with 128GB ram in mobile form factor for ~$2200. The same thing costs $3700. Same SoC, same memory.
