lmao. EV ram is the new ICE catalytic converter
A modern ICE car would have both.
It’s not so much that the cars use ddr5, I doubt they do. The problem is slop generators have booked the manufacturing capacity of the fabs for the next while meaning other chips can’t be produced or produced at a smaller volume.
According to this reverse engineering effort, Tesla MCUs have 4GB of DDR4 onboard.
That is just the MCU, mind you, and I’m not sure what exactly it’s responsible for besides media, but besides whatever AI nonsense they use for self-driving which might have a good chunk of RAM onboard, it seems likely to me that most other computerized components are just using SOC (system-on-chip) processors with integrated onboard memory, not dedicated DDR. I am not an expert though, and may be wrong.
New new form of stealing people’s catalytic converters
The verge Vergecast podcast did a piece on RAM, and it’s well worth a listen. They talk about all sorts of RAM related things, the RAM in a Cybertruck being one of them. Sorry, I don’t remember the details but I remember it being lower than I thought; 8GB, maybe 16gb. Give it a listen.
8gb is much more than i would expect.
Like wth would the car’s shitty computer even be doing to use 8gb? They aren’t playing games or running local big machine learning models. Highly doubt that even the crappiest spyware would be able to benefit from so many resources
Self driving?
Downvotes aside, all swasticars have the built in capability for their “self driving” and that processing is performed locally on an onboard computer with ram.
ah, i think you got me - in my mind object detection and depth perception can use this much
It would be embedded. Not on sticks.
It costs more to carefully cut the memory ICs off a motherboard and repackage them than to just buy RAM.
In rare cases it can be done (like how Chinese shops resolder GDDR to make 48GB RTX 4090s), but I don’t see EV RAM being worth it.
But to answer your question… some self driving systems or even infotainment systems do have a somewhat substantial amount of RAM.
Pro tip: go for the motor. Or the battery, if you can swing it.
The AI overview says about the 24-25 stat is about 90gb but that’s not the main driver for the shortage. It’s more due the first bit of my statement - AI. The companies creating these AI models are sucking up all the RAM.
So you used AI to generate an incorrect answer and then blamed it on said AI use?
lul, the world is so fucked :D I can’t even.
Bro if you don’t have any clue about the answer, just don’t answer.
90GB is an absurd number for two reasons:
- That’s significantly more RAM than any car has
- RAM capacity is in powers of 2, which 90 isn’t. You could do 128GB, which is an even more absurd amount, or 64, which could be reasonable for a crazy infotainment system.
Don’t trust AI to give you answers if you don’t know how to tell when it lies to you.
It said the average was 90 nand+ram
So its mostly not RAM.
t… thanks?
is it ddr5 though.
