Does that make it the most advanced AI chip in the world? No! In fact, frankly, you're trying to have a technical discussion about a bullshit term. Tesla isn't producing an AI chip, they're producing a scalar product chip. It does a 96x96 Mult-add and that's basically it.
How does it do on any of the standard AI benchmarks? Oh it can't run any of them because it's not got support for any of them because it lacks many of the basic features of what any normal person would consider a chip capable of doing AI work.
It is the best chip to run the convolutions and pooling of 1 neural net that Tesla thinks it will want to run. It's the best 'AI' chip in the same way that the chip Nokia produces for it's mobile backhaul is the best 'neworking' chip.
The point is that the chip they're trying to compare their custom ASIC to is capable of running several AI frameworks none of which the ASIC can. Hell it can't even run single precision floating point operations.
Tesla has the best chip in the world for the one neural network they want to run. I bet you good money their custom ASIC sucks at running Waymo's AI workload.
