HW3 reacts faster (lower latency), so is a lot safer. This is why lane shift works better. But if someone unexpectedly crosses a street; HW3 will react a lot faster too. Thanks for this nice comparisation! Looking forward to our HW3 upgrade too!
Great video to see the difference ,now I am on 2.5 HW will be interesting to see how the re wright on HW3 is,when Tesla gets round to fitting it, one hopes soon . Steven are you getting the traffic lights and stop signs in your visualization ?
Well, there’s the fact that hw2 does not rake vones into account and just drives straight into them. It doesn’t recognize speed signs or traffic lights etc. There are a lot more features that make it worth it. But so far, the test points will indeed not be too different because AP us basically running in a virtual machine on the new chipset
HW3 is probably not even utilized to quarter of its potential yet. At the moment they are mostly using same neural networks on HW3, just maybe slightly higher resolution input, and faster update rate, so it can react faster, and get more data points for movement estimates, thus reducing noise. That is why the disappearing lane recovery is faster. Also while HW3 is impressive, and a definitive leader in the car driving tech by big margin, it is still has a lot of design dictated by some tradeoffs like power limit of the power supply to the old HW2 and cost. It is limited to about 36W per one FSD chip, for about 80W for a whole board. It uses 12nm manufacturing node, and just 6 billion transistors. It is rather small chip by modern standards. Something like chips in your desktop or high end android phones, can be using 10nm, or 7nm, or soon 5nm in next Apple phones. For example Apple A13 in iPhone 11 has 8.5 billion transistors using 7nm process, and probably uses less than 10W, and costs about ~80$ to manufacture (but hundredths of millions to design first). Apple A14 will have 11.8 billion transistors in the same area and power. And of course there are even bigger chips (~35 billion transistors), but they are too expensive to put in the car. The current chip is fully capable of being sufficient for many years to come, and maybe only in 2025 we will see update. Even then the current HW3 should be capable for level 4 driving once the software is developed fully.
The chip might be ready, but I personally don't see a path to FSD with the current sensor suite. It is blocked and blinded in way too many circumstances
@@StevenPeeters Yeah, the front facing camera is prone to not working well in full direct sun view. That must be fixed before FSD. A better camera and higher dynamic range and software improvements could help.
Do you have any problem connecting the car with the app after change to mcu2? If my car and a friend's car do not have sentry mode activated or the car is charging, it is not able to connect with it. it is as if when the car is sleeping the app is not able to wake it up
Nice comparison! But... you really need to try to pronounce the "th" better :D "3rd lane" becomes "turd lane" and "hardware 3" becomes "hardware tree" :)
@@StevenPeeters I know, English is not your native tongue - and it isn't mine. So there's always an accent. But in this case it just leads to funny words :) so don't take my comment too serious
katze_sonne no offense taken whatsoever. I’m actually glad to be informed about it, so I can improve (even though by now it is probably a habit that’s hard to unlearn 🧐)
Es ist nicht so leicht Steven beim Sprechen zuzusehen. Man muß ständig seine inneren Zähne anschauen, die ein wenig wie kleine Vampierzähne wirken. Die schwarze Brille macht die Sache nicht weniger Gruselig.
Only Steven Peters has a video comparing the two HW versions using the same SW version ! 🤩
I got my HW2.5 upgrade to HW3 by setting up an appointment in the app. I wanted to make the same video but I am too lazy. Good thing you did it :D
😄 LOL
Which car? Which country?
Made a small purchase from your shop, well done with the endeavor. I really hope your new hardware gives you as much joy as your videos give me.
Thank you
Bedankt Steven, well done. I look forward to your comments on 2020.36.10 with red lights & stops recognition in beta. 😊
Very good comparison

Excellent video, thank you!
Solid video as always! Nice comparison!
Thanks

Yes, I do see the lights. With the next update the car also stops for them. That might be a completely separate test suite then 😎
Did you hear anything from the service center regarding the fender cameras?
That will be looked at next Friday...
Before Re-write, nothing dramatic change will happen.

I have HW 2.5 (tesla model 3)... Im getting upgrade tomorrow to 3.0... but what about software? will I get a new "3.0" autopilot sw aswell?
You will get new firmware installed. Might be same version number but it needs a different build

No, I do not have that issue. I did have it with MCU1 just before the upgrade. But I have a mobile hotspot in my car, so it's almost always on WiFi.

Thanks for pointing that out. I’ll try to improve on that.
Was looking for that comment :) It drove me crazy...
