In my regular research (behind a paywall), I have been saying for a while that I think the future of AI is not large language models (LLM), but small language models (SLM) run on local desktop computers or even mobile phones.
Hence “x86 (desktop OS) space”. It’s not intrinsically part of x86, but it has settled in as a conventional piece of x86 desktop OSes. x86 consoles and ARM desktops don’t assume the same principle, and they can get a lot more mileage out of SoCs as a result.
Yes. The issue is not that ARM systems don’t/can’t communicate with a dGPU over PCIe. It’s that x86 systems (edit: running conventional x86 desktop OSes) have to basically pretend they’re using PCIe to communicate with an iGPU. (Not literally, but a lot of the primitives they use were inherited from AGP/PCI and don’t make a lot of sense for an SoC.)
I wouldn’t say it’s totally legacy. (v)ram bandwidth does matter and while the Apple M-series chips do well with their unified memory architecture don’t forget it’s fixed because it’s part of the CPU chip.
That has nothing to do with x86 though…

Aren’t there arm workstations that still take pcie cards and have a similar architecture to x86?
