If instead AMD made a graphics card with expandable DDR5 slots, that'd be life-threat to Nvidia's business model.
- exitb 3y agoIsn't that a latency issue?
- Cheer2171 3y agoWhy would a GPU with 1/3rd of the memory bandwidth and no CUDA be a threat to Nvidia?
- bryanlarsen 3y agoAnything without CUDA is not an existential threat, but anything that supports PyTorch and provides lots of RAM at a low price is a monopoly-profits threat.
- reacharavindh 3y agoWould AMD be able to produce a core design with unified memory like that of Apple’s M series such that a Ryzen core with integrated GPU cores _and_ unified memory? If they do, it will open up a lot of interesting doors. As good as Apple’s M series CPUs are, one cannot (reasonably) simply build server rigs with them and exploit all that power..
- bryanlarsen 3y agoThey've already created such a design. It's called the MI300A and costs $20k.

- bnolsen 3y agoThat would eat into their discrete gpu sales. It would take courage to cannibalize their own sales.
- p1esk 3y agoA regular CPU supports Pytorch and has lots of RAM at low price. The problem is memory bandwidth.
- bryanlarsen 3y agoThere are lots of people finding M2 Max faster than graphics cards for their tasks.
- p1esk 3y agoHow does memory bandwidth of M2 Max compare to memory bandwidth of Ryzen 8700G? 400GBs vs 80GBs? Exactly my point. 400GBs approaches lower end graphics card territory (e.g. 3060)
- aseipp 3y agoNo, it wouldn't. Socketed DDR5 doesn't have the bandwidth necessary to feed a massive compute complex like the one in a modern graphics card.
- anticensor 3y agoDIMM does not, but CAMM does.
