Maybe give me lots of money to give Nvidia for a card with more memory then?
Nvidia have held back the majority of their cards from going over 24GB for years now. It's 2024 and my laptop has 96GB of RAM available to the GPU but desktop GPUs that cost several thousands just by themselves are stuck at 24GB.

This is like Intel and their refusal to support ECC memory; when AMD does on nearly all Ryzens. — Note: your laptop is probably using a 64-bit memory bus for system RAM. For GPUs, the 4090 is 384-bit. That takes up a lot more die area for the bus and memory controller.
- versteegen 3y agoBut GP's laptop with 96GB of unified memory would be a M2 Max Macbook or better. The M2 Max has a 4 x 128-bit memory bus (410GB/s) and the M2 Ultra is 8 x 128bit (819GB/s), versus a 4090 at 1008GB/s. But see here for caveats about Mac bandwidth: https://news.ycombinator.com/item?id=38811290 https://news.ycombinator.com/item?id=38811290

- smcleod 3y agoIt wouldn’t be a local model if it has to work on AWS.
- DSMan195276 3y agoIsn't there the risk that if they give the gaming cards enough RAM for such tasks then they'll get bought up for that purpose and the second-hand price will go even higher? I guess my point is, rather than give the cards more RAM, the gaming cards should just be priced cheaper.
- chaostheory 3y agoWhich laptop models share system RAM with an Nvidia RTX cards?
- stygiansonic 3y agoOp probably referring to an M series MacBook since it has a unified memory architecture and the same memory space used by both cpu and gpu
