500% more reliable than humans! Tesla: Radar is back!

If your memory is still there, you should still remember Tesla’s harsh words: its own cars don’t need any radar.

However, it didn’t take long for Tesla to be slapped in the face by the speed of light.

It was first revealed that in June last year, it applied to the FCC to use a new radar in its vehicles-described in the document as a "76-77 GHz automotive radar."

Subsequently, in December last year, a document was "leaked" that an application was submitted to the US Federal Communications Commission (FCC) to extend the confidentiality period for 60 days, and the specific details and appearance photos of the radar were not made public for the time being.

All these signs indicate that Tesla is slapping itself in the face.

No, German fans recently uncovered Tesla’s vehicle change application submitted to European regulators, completely confirming Tesla’s new model rumors:

Equipped with the latest autonomous driving hardware HW4.0, new chips, new sensors, millimeter-wave radar, new models of on-board computers, braking systems, vehicle parameter calibration, etc. have all undergone changes.

Later, a master (well-known overseas Tesla blogger Greentheonly) directly announced the real machine picture of Tesla Hardware4.0 computer board. From the exposed pictures, we can see that the size of Hardware4.0 (hereinafter referred to as HW4.0) has been improved compared to HW3.0.

According to specific information picked up by German Tesla fans, this update mainly has three aspects:

The first point is that the front three cameras have been changed to two, but they have been increased from 1.3 million pixels to 5 million pixels. Two new side cameras (L-FF-Side and R-FF-Side cameras) and one front camera have been added. Camera (F-SVC).

To a certain extent, although the number of cameras has decreased, because the accuracy of the cameras has increased, the quality of the images they capture has also increased, which has resulted in an increase in the amount of data that the computer needs to process. Reduce data volume as camera data is reduced.

The second point is the top priority of this upgrade. Tesla actually "picked up" the radar again!

It is reported that the newly added Phoenix high-precision radar is a high-precision 4D millimeter-wave radar. Compared with ordinary millimeter-wave radars, it has height data and can better distinguish the height and type of obstacles, thereby deciding whether the vehicle should stop or stop. Keep driving.

Of course, compared with ordinary millimeter-wave radar, 4D imaging millimeter-wave radar has a higher resolution and is more powerful, but if the comparison object is replaced with lidar, it is still incomparable. The only problem LiDAR faces now is cost.

As soon as the cost drops, other millimeter wave radars will be directly crushed.

The third point is that computer chips have also been upgraded.

The number of CPU cores has increased from 12 to 20, with a maximum frequency of 2.35GHz and a default frequency of 1.37Ghz. The number of TRIP cores has increased by one compared to before, with a maximum frequency of 2.2GHz.

The CPU is still the AMD Ryzen Zen+ V180F embedded processor, with a main frequency of 3.8GHz, 4 cores 45W, 512kb L2 cache/core, 4mb L3 cache, and the GPU is also based on RDNA2 based on AMD Radeon Navi 23, with 28 sets of computing units. , 2.79GHz main frequency, using a combination of 16G LPDDR4 memory + 256G NVme solid state drive.

You may be curious, how much has the computing power of the new HW4.0 computer been improved? Dark Horse personally guesses that the computing power should be improved, and I can personally guess that it is close to 100%.

Because according to Green's measurement, the idle power consumption of HW4.0 is about twice that of HW3.0, about 80W. In addition, the number of CPUs has increased from 12 to 20, which is not a double increase. So comprehensively Taking into account overclocking and the number of CPUs, it is relatively normal for HW4.0's computing power increase to be around 100%.

Theoretically speaking, the article should almost end here, but Musk started to promise the public that this new Tesla automatic driving system is at least 500% more reliable than human drivers!

So, can old car owners enjoy such a good thing?

Emmm, Musk also gave the answer. The original words are: "The cost and difficulty of upgrading HW3.0 to HW4.0 are quite high. I think it is not economically feasible."

High emotional intelligence: more difficult and more costly.

Low EQ: No.

Originally, these words were nothing. After all, just from the comparison of the shapes of the two generations of computers, it can be seen that car owners using HW3.0 cannot upgrade their computers to HW4.0 alone.

However, Tesla has said a long time ago that all Teslas have hardware that supports fully autonomous driving. Now that you suddenly say you don't support it, it's a bit unacceptable, right?

It is true that Musk may have said these words in the past to promote Tesla and build momentum, but for the consumers who believed this statement and ran to buy Tesla at that time, this was undoubtedly deceiving. .

Perhaps, for both Tesla and Musk, slaps in the face are the norm.

It’s the old saying: buy early and enjoy early, buy late and enjoy discounts.
