also he did not serve us an advertisment ... unlike what this channel is starting and will become very shortly.. ( and props to munro sell out and make its money for old man and company ) but my eyes will stay in the future shill free..
did not need a battery bank.. dont need a shaver... come on.. if you want rev from advertiment.. make a separate sponsored video and tear it down and say whats good about it!!! we would find value in that and so woud they !!! KEEP TRUE TO YOUR VISION
Oh David! That was frakking awesome thank you for your kaupapa. Now repeat after me "I will start my journey to health with 6 squats a morning in the shower...😍😇😎 We need you dude.🤠
Hi Dave, quick comment on the memory modules - Those are GDDR6 DRAM modules, similar to what are found on graphics cards. They are significantly faster than traditional DDR RAM that you would put in your computer, and they are in what's called "clamshell mode" where there's a DRAM module on the top and bottom of the board. This is important for GDDR6, because it allows you to double the capacity for of a GDDR6 controller (which would be important for running larger inferencing models.) The part number on screen is for a 14Gb/s module, which is not the fastest model that Micron makes, but it's significantly cheaper and more reliable from a signaling and board layout standpoint. On each chip, there are 4 interfaces, each capable of 56 Gigabytes/second. I work on GDDR memory (not at Micron or Tesla) so when I saw a familiar part number, I figured I'd share what I can! Thanks for the presentation!
If I can tack on some more technical details, those are 16Gb (Gigabit), not 16GB (Gigabyte) modules. It seems like a LOT of people commonly conflate these two units, but the difference is a factor of 8 (a byte is 8 bits). The capacity of memory modules is usually measured in bits, not bytes.
The level of technology here and how fast it is advancing is so mind blowing. dont think most people can grasp just how fast it is moving. I am amazed how how people keep up with it.
Yes! Also, Cory pivoted the educational/entertainment point of the vid there at the end. He seamlessly morphed from teacher and lead engineer to salesman. There are a lot o companies around the world with endineers and thought leaders in their ranks. The Gordon Moores o this world weren't Titans o industry from the begining. There are genius young people watching, learning, and absorbing content like this like sponges. One or more of them is making up their mind on a degree program for lean design as we speak. The future of design and manufacture will be fascinating to watch!
I just received an an e mail from the regional sales manager categorically stating the the upcoming delivery of my new model s will have HW4 but no USS or RADAR !!!! Needless to say i cancelled the order forfeiting my deposit
You have such good timing! So many times I take a break and want a bit of quality 'TV' and see a Munro post within the last 10 or 20 minutes. Good Job!
Great closing. Love it when engineers respect each other and the work they do for the client. Keep up the great work, we love seeing the value you guys provide to the community all over the world.
Cory, Dave, you guys make watching technical detail stuff like diving into HW3 and HW4 differences interesting, even for someone who has no knowledge of car internals. Thnx to the team at Munro making very interesting observations and showing design decisions I have been looking with a total different eye at my own car . Thanks for all your excellent and detailed critical reviews that you brought to us. I would never image siting through hours of video’s of guys showing me car bodies and how well or not so well they were put together. I especially liked what you showed how getting rid of a few small parts that cast a few dollars end up saving the company millions of dollars. And we’re talking just about the part cost. But leaving out the handling and manufacturing of these parts will make out an ever bigger cost saving and even time saving. This brings Elon’s mantra “ the best part is no part” even more home.
Fantastic video! Personally I love hearing about the computer side of things, especially considering most people refer to Teslas as "computers on wheels". To that end, would have loved more technical detail on the CPU/GPU in the infotainment (if only for completeness), but I'm sure it's been covered elsewhere.
Thanks for answering the question at the end about a retrofit for the current owners of Teslas. Great presentation. The future upgrades for FSD looks exciting with potential improvements.
If I have multiple notifications for UA-cam MUNRO LIVE always gets watched first. Always an articulate expert who can explain the unexplainable to us nerds out here.
Thank you Dave and Cory, but especially Dave, for the insight and breakdown of the HW4 system. I don't come from an engineering background (but from a lower level tech background) but this channel has become my go-to for learning all kinds of engineering and is always a pleasure to watch. Should be required viewing for young and old aspiring engineers alike. Big thumbs up!
Great presentation. Could you do a show about the technical differences between the old Tesla radar and the new Tesla radar? For example: What the new radar can see vs what the old radar can see?
Dave you are an amazing guy!! Notice how he looks down when Cory praises him. I don't know why but this was quite a weteyed moment for me. This shows the Munro work enviroment!!!!
Great to meet and learn so much from Dave. He's super knowledgeable and a nice guy. Cory was great as always. All of you guys at Munro & Associates make a great team including the head honcho himself, the much admired and respected Sandy. Keep up the great work.
Thanks Corey and Dave, great info. I saw some chatter on social media about HW4 and I'm so glad to have a Munro Live video on the topic so I don't have to waste hours sifting through uninformed opinions!
The best channel to learn. I can’t believe we get this kind of content for free! So thankful for Monroe’s team, very informative and well presented video
Dave, excellent presentation and in depth knowledge. As a network engineer with over 40 yrs experience, I remember this LAN technology pronounced E’-ther-net vs eth-er-net.
Great video. Was wondering. Can someone take out the ai system and build their own mini tesla? I see a lot of ppl trying to build a mini (powerwheel size), programming everything themselves. Instead of figuring everything out on your own, just install the ecu? Maybe more complicated than it sounds lol. Great video
The reason for the extra space on the FSD computer is the form factor. They moved the GPU to the main board of the infotainment board, which was dictated the size of the infotainment board and thus the enclosure. Also, more connectors on the side diictated on one of the sides dictated that dimension. It's very unlikely that they'll do a new revision with same HW4 chip - Tesla had a LOT of time to design it and would likely placed everything they needed ahead of time. As for retrofit, we 'know' that initially HW4 will be used in cars with the same number of cameras, so it brings value even with existing sensor locations. If Tesla deemed necessary they can build a retrofit HW4 board that would have similar form factor and connector locations with HW3 computer. They can easily fit the HW4 chips and comonents around it as we know there's spare space on the current board. Finally, as for the radar, I've worked on car radars and can confirm that the original radar Tesla was using was useless. It had no or very little Y-axis resolution so could not differentiate a wall from a bridge, the resolution was low and the data rate was very limited. The new radar uses 2-generation ahead of the original one, has Y-axis resolution, more cameras, higher 'frame' rate and better z-axis (distance) and x/y-resolution. It makes a world of a difference for Teslas applications which are much more than not hitting the car in-front like what most vendors currently use radars for. Elon said several times that hi-res radars bring value and his comments for removing the old radar was due to false detects with low-res radars which caused more damage than good.
@@royh6526 I don't think it will be needed, but if at some point Tesla realizes that HW4 is required for RoboTaxi, it can build a HW4-based retrofit for older S3XY and only provide it to people signing up their cars to the RoboTaxi network. Building a retrofit is always possible (assuming it uses existing sensors) - the question is if it will be needed (I strongly believe HW3 can do robotaxi) and if the cost is prohibitive or not (including possible legal action to Tesla selling FSD and promising HW3 will be capable to support it)..
@@денисбаженов-щ1б Semi was planned to have 4680 cells from the beginning. 4680 cell development took years longer than expected. Finally Tesla decided to bring out the initial Semi with 2170 cells. Higher cost and increased weight penalty, but they couldn't wait any longer.
FINALLY someone that understands the problem with radars and how they are very much not created equal. It was fine for autopilot but an active detriment for FSD or even just getting more advanced features or AP unless the camera vision stack started disregarding inputs from the radar which at this point makes it sort of useless.
Excellent presentation, Dave. Great insights. And top-notch leadership skills on display Cory, showing deep appreciation to Dave and the Munro team. Awesomeness!
Dam- as always another #masterclass. And.. more Corey / Dave duo please! First time I’ve watched Dave here and much like the whole Munro crew- just a true master at his craft. Not a single media channel even comes close! To steal a Elon quote- second place needs a telescope to catch a glimpse of you guys. Just awesome!
Great analysis from Dave! I really appreciate the other Munro team members sharing there deep knowledge and insights openly to the community like this and getting to see all of the new faces! :) thank you to all the Munro team
Well explained Dave. Munro live in general is one of the best channels on UA-cam today. All of them are extremely intelligent & so professional. In regards too the HW4, I believe Musk did say it was not something that could be retro fitted.
with more memory, it's safe to assume the memory bandwidth was also increased. Looking at the pastebin, HW4 has 2 ethernet ports and list 23 FSD sensors
Excellent review of changes, much appreciated! Wouldn't be surprised to see they moved to 7nm process, since the phone and gpu industry has left that node, it's got to be cheap from Samsung.
Could we see an in-depth analysis of the various charging stations, as this is turning out to be an important factor in choosing ICE Vs. EV, and one EV against another. It would be interesting to see how these units differ internally both individually and as part of a network of chargers, and how they interact with the cars they supply power to.
You probably already have this thought. My thoughts on the more RAM is 1. Higher resolution camera= more needed memory 2. Often sometimes when you redesign something, the older version of chips is going to be end of life soon and so it makes sense to plan new items with the current version so it's supported for 5 years or so. Also, it may actually be cheaper.
I like that we can see and understand what Dave's talking about. (When Uncle Sandy went through the interior of the Audi in an earlier vid, that wasn't always the case.)
Dave has all the skills of a master lecturer with all the knowledge necessary to explain things thoroughly. a true joy to watch and listen to..

Great video and appreciate the work you guys and gals do...
Much appreciated!
Excellent teamwork. As someone who works in an adjacent sector to Dave's work, I give kudos for explaining it details very well.

great videos as usual, nice to see another member of the Monroe team.
Much appreciated!
all of these non-sandy videos have been getting even better!
Clear. Concise. Technical as needed. Thank you Cory and Dave. Wonderful brain trust. The World is fortunate - because you share.

Great job David, you were very well spoken and informative, I hope we see you again.
This was excellent, please more! Super interesting to see the boards and chips.
The screen helped us see and focus on the discussed components.
The key advantages and nonretrofitability were well covered.
Nicely done, guys!
I was so in tune with the the two that I almost forget to thumbs up the this breakdown video. Thanks!!
Glad it was helpful!
Thanks Corey and Dave, great info. I saw some chatter on social media about HW4 and I'm so glad to have a Munro Live video on the topic so I don't have to waste hours sifting through uninformed opinions!
Our pleasure!
Love the video! "Unique New York" is an old acting exercise btw. Anchorman was using that as it's a standard pre-show warm up :)
The Joy of watching intelligent people speaking on interesting things. Glad to be here.
Great video. Thanks Cory and Dave for sharing details of the new Hardware HW$.
44 years engineering in big auto electrics world wide and at last, my kinda channel.
Wow great 👍 More of Dave please 😊😊
The best channel to learn. I can’t believe we get this kind of content for free! So thankful for Monroe’s team, very informative and well presented video
Our pleasure!
Working in IT I very much appreciate the technical breakdown. Dave is great! Not all geeks can explain things well
Whos that guy on the video with Dave?
Thanks for the great video Dave!!
Dave, excellent presentation and in depth knowledge. As a network engineer with over 40 yrs experience, I remember this LAN technology pronounced E’-ther-net vs eth-er-net.
Thanks Munro!
Fascinating piece of tech and very nice explanation from Dave!
My pleasure!
Almost teared up at the end. You guys are so lucky to be doing something you guys love together with people you like.
Dave is awesome!
Great video.

You bet!
Dave is great. He has a great humble way on explaining things. Thank you Dave!
Really enjoyed this. Thanks to you both.
A wonderful watch from the UK. Would love to watch a live show of you guys in the UK. Good stuff Dave.
This was extremely insightful. Thank you Dave!
Glad you enjoyed it!

Many many thanks Cory and Dave. Learned a lot more about HW4 from your video. Kudos to greentheonly for his scoop on this new tech from Tesla. :)
Thank you Munro team great informational video! 😁🙏🏼🙋🏻♂️
Our pleasure!
Awesome stuff! Thanks gentlemen!
Our pleasure!
Dave's good on camera, Thanks!
We agree!
Great job of showing the inside OUT💥
Fantastic ending to the video. Great job on this one.
NEED MORE DAVE! 🙌 NEED MORE DAVE! 🤘
cory doing some shaping work hot damn your effort is impressive and he's blasting with confidence and competence
with more memory, it's safe to assume the memory bandwidth was also increased. Looking at the pastebin, HW4 has 2 ethernet ports and list 23 FSD sensors
Very nicely done Dave!!!! Hope to see you doing more of these.
That was a really informative video, I hope Dave improves his health a little to be more comfortable and to keep providing his great knowledge.
One of the best videos you've done 👍
Wow, thanks!
Excellent review of changes, much appreciated! Wouldn't be surprised to see they moved to 7nm process, since the phone and gpu industry has left that node, it's got to be cheap from Samsung.
This is a great and detailed description of HW4. You guys bring so much to the party. 😎
Nice job! Always love these videos.
GREAT video. Answered all my questions.
Super info/video!! Thanks a million!
Glad you enjoyed it!
Thanks for the analysis
More EE stuff please! Great info.
Love the detail guys!
Could we see an in-depth analysis of the various charging stations, as this is turning out to be an important factor in choosing ICE Vs. EV, and one EV against another. It would be interesting to see how these units differ internally both individually and as part of a network of chargers, and how they interact with the cars they supply power to.
Great job explaining the new hardware Dave!!!!
Amazing analysis! Thank you for the great job you do!
Cory is a class act. Well done and great video.
@ 1:18 _"Talk to our team"_ You might have been right the first time ;)
Spectacular content, thanks! Just knowing it's Linux is fascinating, better understanding automotive electronics packaging equally cool. All the best
LOL! I love seeing Sandy trying to sell buttons.
Great video as always.
Thanks again!

This was great! Rivian ADAS and infotainment system teardown next?
Thanks for detailed explanation! So helpful & beneficial!
I loved it. This one was great.
Could you do a episode on the differnt communication protocols and how they reduce wire size and amount? I likes davids analysis on this.
Outstanding video gentlemen.
Shout out to Dave. Brilliant.
Keep bringing Dave on Live!!!
