The "brains" behind Tesla's self-driving tech
Pretty interesting article about Tesla's in-house chip technology. Tesla's in-house chip is 21 times faster than the older Nvidia model Tesla used. And each car's computer has two for safety.

lots of big numbers thrown around in that article, but doesn't mean much. "21x faster" - how measured?
Each Tesla AI chip runs at 2GHz and performs 36 trillion operations per second. For another, it's got an extremely limited set of instructions it can process. And it's got a gargantuan 32 megabytes of high-speed SRAM memory on the chip, which means it doesn't have to wait around while fetching data from much slower conventional DRAM memory. it IS true though that tesla now has a VAST amount of experience and DATA from their cars, which is improving every moment. this means they're YEARS ahead of other car makers who have 'dumb' not-connected vehicles, and thus almost no data. i think other car makers are very scared of tesla, and rightfully so. |

36 trillion? that does not seem accurate. that's the old 'RISC' idea (reduced instruction set computer) and while it makes the processor design simpler, it also means a LOT of execution of those instructions are used to do complex things sometimes negating the benefit of being able to do so many 'operations'. but cell phones and tablets use risc, and obviously it works great. 32MB of cache is nice, but since cars stick around for a decade or more, you have to be somewhat ahead of the curve, especially if you're trying to do ambitious things like autonomy. it IS true though that tesla now has a VAST amount of experience and DATA from their cars, which is improving every moment. this means they're YEARS ahead of other car makers who have 'dumb' not-connected vehicles, and thus almost no data. i think other car makers are very scared of tesla, and rightfully so. |
So sophisticated yet they're building cars outside in a tent. What a joke of a company.

Big Whoop.
While I admire what SpaceX has accomplished, Musk seems to be a bit of a nutjob when it comes to promises not kept. And I wonder if the new Porsche will just clobber the Model S. It's getting a lot of positive press and supposedly 300K pre-purchase deposits to date. |

You'll own an EV at some point, maybe not a Tesla, but you should thank Tesla for the one you end up with. They're forcing the entire market to move and bring better product to the consumer. SMH. |

They are pretty different cars...one is a midsize sports sedan while the other is a full size 7 series fighter.
The Model S will clobber it in straightline in Ludicrous while the Porsche will probably clobber it in handling and sustainable output. The Model S will get 350 miles of range while the Porsche will be around 225 miles. I bet the Porsche will have better build quality and interior though. and there's this. :p https://www.businessinsider.com/tesl...erience-2016-8 |

https://www.businessinsider.com/tesl...erience-2016-8 It feels like you're being launched into orbit, basically. But that's an issue when you get right down to it. Because Ludicrous Mode isn't that great in practice, or at least in everyday practice. It's best enjoyed in moderation. Going fast in a Ferrari never gets old because ... it's a Ferrari! But Ludicrous Mode in a Tesla is fun the first few times, and then you just don't want to go through he battening-down process that's required to get ready to fulfill your need for speed. |

I hope you're posting this ironically. :)
and for many, they've got much higher priorities than going 0-60 in a 'ludicrous'ly short amount of time. |

not at all. for many, and i mean MANY, the thrill of driving a FERRARI will never be outdone by an electric 4 door sedan, now matter how fast the electric car is.

Shouldn't you be comparing a Ferrari to the upcoming Tesla Roadster and not a sedan?
and hard to compare a ferrari (something i hardly ever see and have only been in one once) to a car that’s not even out. :p Count me in to this way of thinking but I'd say a great many people disagree, or at the least put a massive emphasis on acceleration. As for electrics not being fun watch the Tesla racing channel on YT that guy always has a smile on his face blowing the door off of just about everything. |
