Hi there, I want to share some thoughts and want to hear your opinions on it.
Recently, AI developments are booming also in the sense of game development. E.g. NVIDIA ACE which would bring the possibility of NPCs which run an AI model to communicate with players. Also, there are developments on an alternative to ray tracing where lighting, shadows and reflections are generated using AI which would need less performance and has similar visual aesthetics as ray tracing.
So it seems like raster performance is already at a pretty decent level. And graphic card manufacturers are already putting increasingly AI processors on the graphics card.
In my eyes, the next logical step would be to separate the work of the graphics card, which would be rasterisation and ray tracing, from AI. Resulting in maybe a new kind of PCIe card, an AI accelerator, which would feature a processor optimized for parallel processing and high data throughput.
This would allow developers to run more advanced AI models on the consumer’s pc. For compatibility, they could e.g. offer a cloud based subscription system.
So what are your thoughts on this?
Your GPU is an AI accelerator already. Running trained AI models is not as resource demanding as training one. Unless local training becomes universal, AI acclerators for consumers make very few sense.
The newest gen GPUs have sections dedicated to AI already, so we effectively already have dedicated AI accelerators.
Yes there are but the op is talking about discrete AI accelerators…
Unless the AI processing is much more specialized than graphics, I think manufacturers would put that effort into making more powerful GPUs that can also be used for AI tasks.
They would try to alleviate the cost on running GPU by making an AI accelerator chip like Tensor Core, but it’ll get bottleneck by limited VRAM when Neural Net models require steep amount of memory. it’s more productive to have something like NPU that runs either on RAM or by it’s own memory chips offering higher amount of capacity to run such neural net and avoid the roundtrip data copying between GPU and CPU.
We saw this happen a long time ago with PPUs. Physics Processing Units. They came around for a couple of years, then the graphics cards manufacturers integrated the PPU into the GPU and destroyed any market for PPUs.
Look into what Mystic AI was doing. It’s effectively what you were talking about but based in reality :)
It was before my time but… If physX cards are any indication, then no.
The PhysX debate was also before my time. But I read into it, and it seems like they solved it partly software based. But with AI we are talking about hardware limitations, especially memory.
Currently, AI operations mean a lot of time-consuming copy tasks between CPU and GPU.
Absolutely, I would suggest looking into two separate devices that focuses solely on AI acceleration:

Two very interesting articles. Thank you for that!
Especially the analog processor is a game changer with having the computation directly in memory. Generally, analog computers are a very interesting subject!
Good question, but I’d say that the same train of thought went through dedicated physics cards. I’d guess that an AI card should have a great value proposition to be worth buying.
For compatibility, they could e.g. offer a cloud based subscription system.
I’m not sure where you’re going with this, but it feels wrong. I’m not buying a hardware part that cannot function without a constant internet connection or regular payment.
