前天Tesla所宣布的新車將全部配備新的硬體以供未來自動駕駛使用

而其中的運算單元將會是NVIDIA's new Drive PX 2 AI

Drive PX 2這套系統其實是一個專門為車子所打造的超級電腦

關於這套系統的簡單介紹可以看這裡：

這套系統裡面有12 CPU cores，號稱有著150台 MacBook Pro的運算能力

8萬億次浮點運算能力大概等於是6張Titan X顯示卡
(題外話，Titan X這張顯示卡在台灣預估價格會是4.5萬台幣上下，目前還沒發售)

Volvo XC90是第一輛搭載這套系統的車型

當初是以100輛XC90搭載這套系統去做深度運算與學習

用在一個叫做"Drive me"的試用方案中

而現在Tesla將會把他標配在全車系全車型


Nvidia並沒有透露是以多少價格提供給Tesla這套系統

但是在今年稍早的時候，Nvidia是以一套1.5萬美元的價格提供給OEM廠商


寫到這覺得根本超值

Tesla除了Drive PX 2這套系統外

另外的硬體還包括8個鏡頭，超音波傳感器和雷達天線

只收你5000或8000美元

就連只有3.5萬美元的Model 3也會搭載這套系統(不過如果想用的話就要多付5k or 8k)

這是賠錢在賣這套系統吧

Tesla為了打造自動駕駛技術真的是下了重本

We reported in exclusivity earlier this month that Tesla was going with
Nvidia hardware to power its imagine processing platform called ‘Tesla Vision
’, but we couldn’t pinpoint which product Tesla was going to use exactly.
While we discussed the possibility of using Nvidia’s new Drive PX2 AI
computing platform for self-driving cars, we also noted that the product is
fairly new and expensive to be included in all new Tesla cars coming off the
line.

We thought the theory was confirmed when Tesla CEO Elon Musk said this week
that the automaker ended up choosing the ‘Nvidia Titan GPU’, an
off-the-shelves but powerful GPU card, to power ‘Tesla Vision’, but as it
turns out, Musk misspoke and Nvidia confirmed that the “in-vehicle
supercomputer is powered by the NVIDIA DRIVE PX 2 AI computing platform.”

When talking about ‘Tesla Vision’ in a press call with journalists on
Wednesday, Musk said:

This is a Teslaeveloped neural net. Although it’s somewhat hardware
independent, it can be  we can actually run this on Nvidia, AMD or Intel.
We did pick the Nvidia titan GPU as the main chip for the neural net.  But it
was pretty tight call between particularly between AMD and Nvidia. But
ultimately we felt that Nvidia had the better hardware.

In a blog post today, Nvidia corrected the information (see in full below).
The company also announced that the DRIVE PX 2 is now in full production.

Both the Titan and the DRIVE PX 2 are using the Nvidia’s Pascal GPU
architecture, which might explain the confusion.

The Volvo XC90 was previously going to become the first vehicle to use the
platform with 100 units being deployed through the Swedish carmaker’s Drive
Me autonomous-car pilot program next year, but Tesla beat them to market with
the platform now going into each new Tesla.

Nvidia didn’t disclose the price of the Drive PX 2 platform, but it is
believed to be an expensive piece of equipment. While unlikely to be
representative of the price Tesla is paying for its production cars, Nvidia
was selling the system to OEMs for their development programs at $15,000 per
unit earlier this year.

It likely represents an important part of the cost of Tesla’s new hardware
suite, which also includes 8 cameras, ultrasonic sensors, and a radar
antenna. It’s impressive that Tesla is able to include the system in all
vehicles as a standard hardware and enable its features for $5,000 or $8,000
depending on the options.

Tesla says that the new ‘supercomputer’ powered by the Drive PX 2 platform
represents a 40x processing power increase over its previous system:

To make sense of all of this data, a new onboard computer with over 40 times
the computing power of the previous generation runs the new Tesla-developed
neural net for vision, sonar and radar processing software.

Nvidia’s blog post to confirm the computer powering ‘Tesla Vision’:

Tesla Motors has announced that all Tesla vehicles — Model S, Model X, and
the upcoming Model 3 — will now be equipped with an on-board “supercomputer
” that can provide full self-driving capability.

The computer delivers more than 40 times the processing power of the previous
system. It runs a Tesla-developed neural net for vision, sonar, and radar
processing.

This in-vehicle supercomputer is powered by the NVIDIA DRIVE PX 2 AI
computing platform.

NVIDIA DRIVE PX 2 is an end-to-end AI computing system that uses
groundbreaking approaches in deep learning to perceive and understand the car
’s surroundings.

Our deep learning platform is open and lets carmakers first train their own
deep neural networks on GPU supercomputers. Once loaded into the car, it
processes the networks at high speed to provide the real-time, accurate
response required for autonomous driving.
