- kllrnohj 3y ago> Do people really think such a low hanging fruit was ignored for the past decades? Yes, they do, it's mentioned as some major M1 revolutionary technology all the time. It's utterly absurd, but that's the power of Apple's marketing.
- NikkiA 3y agoHell, the UMA was considered a downside on the original XBOX because everyone was used to each processor having it's own memory bus, so even though the bus was (for the time) a sprightly 6.4GB/s, it was considered lesser.
- buildbot 3y agoI can’t run llama on an intel iGPU, because it OOMs - the memory is unified because it’s in the same space and shared on M1. Not just marketing.
- menaerus 3y agoSo, how much memory is available to your Intel iGPU? What was the machine? If it OOMs, then one valid assumption is that it OOMs because it has less memory available than there is for a GPU on M1 but we can't know that if you fail to mention the specs.
