I'd be curious to see the cost of Tesla's package (they claim it’s cheaper than Xavier) and the power draw.
Maybe I missed something.
There are two types of driving assist systems from nvidia. PX Xavier and PX Pegasus, with the first built to be small 30w self driving systemand is comparable to the the tesla solution in terms of performance power, and the second is a "full" AI system for complete autonomous driving, which is a 500W system.
Tesla solution is somewhere in the middle. Tesla are comparing their new hardware to the customized PX 2 from nvidia, which was a 60W version of PX 2. But nvidia's new hardware (Xavier and Pegasus) are a lot faster even compared to tesla's 70W 2 chip solution. Especially with the new nvlink on chip solution and the tuning gpu/arm cpu solution.
The 500W version of Pegasus is not comparable to the tesla solution, because it is not meant for the cars. A somewhere in the middle solution, like the customized PX 2 with a pegasus version, or xavier solution, are more comparable.
Comparing tesla's solution to pegasus is like comparing a station to a sport car. Tesla's solution is 21 times the original PX 2 according to them, but pegasus in raw power, is somwhere around 30 times without the customization or the better software tesla wrote over time, and without taking into effect the new nvlinks etc.
What I think was the main difference is the 80% price difference. I would expect that with the new nvidia hardware, tesla could get the same performance on a lower watt hardware, since nvidia can move mountains if they really want to.
But tesla need to save money, and they already had the software people, knowledge and experience they earned using nvidia hardware, so they could make a more dedicated chip for their solution, and make it cheaper because it was built in house specifically for their solution.
Since nvidia solution was designed to work not only for tesla's software, but for other companies, they couldn't just make it to tesla's direct specs.
Overall I think nvidia's issue is that they don't actually have end products, and not that their products are bad or worse.
They have middle products that are suppose to work with several systems, and each of their customers want a more specific specialized hardware.
When you look at other markets, specifically the phone markets, this is what apple are doing. They decide to start and design things on their own instead of relaying on others at a higher price tag. This helps you both have a complete control over your product, and reduce reliability, and reduce cost.
I recon that nvidia's solution will work better with the likes of the other big car manufacturers, who might not try to develop something from scratch like tesla, and will be ok with an "off the shelf" solution from nvidia. Tesla are more unique in the matter. BMW, audi, toyota and more, are working with nvidia hardware.
