LPDDR6... that's not enough for speedy inference
Maybe,but memory bandwidth is much better than on the DGX Spark at least.
I hate this RAMpocalypse so much

Not every computing platform is expected to do fast inference.

#13I can feel the scores of messages being sent to the federal government from lobbyists saying what a threat Chinese hardware is to national security.

The motivation for such messages may be greedy, but it doesn't mean the facts aren't wrong: 1.

OH, BUT we have fable! We have AI! of course we can answer these questions? can't we? which is true: America's AI is a super powerful defense against our enemies or America's AI is too stupid to defend against such a threat, and only sactions and import controls will suffice.
Just seems like you're inventing things to be scared of.

#14I'm curious as to the performance per watt. There's no such thing as a free lunch.
no free lunch for a given process node I guess. It's using TSMC’s 3nm N3P.
Re: Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
#15This smells somewhat legitimate and somewhat BS. The architecture itself looks impressive — TSMC 3nm, a 4+ GHz prime core, tons of cache, and a very wide execution engine. And the claimed Geekbench numbers — around *3,945 single-core and 15,221 multi-core* — are especially impressive, if not a little suspicious.
But it’s sorta like, let’s throw everything against the wall and get the biggest number we can. Do they show sustained performance over ten minutes? What’s the power draw when it’s doing 15K? What happens when you put it in an actual phone?
This was done in a cold room. It seems more like a proof of concept for what they could do than something that could actually ship in a phone and sustain those numbers.

Can we audit American corporations?

It depends on the number of channels. The Xring O3 appears to have 4×24-bit channels, so 113.8 GB/s. The iPhone 17 Pro's memory bandwidth is ~76.8 GB/s. Seems fine?

#19Insane if true. Does Xiaomi sell laptops?
Yeah, but they're just normal Intel stuff.

it's a hardware problem, you run into engineering, materials, and physics issues. we're not talking about reverse engineering software
