Hardware 4 in the Model Y comes with reduced ram and storage
Greentheonly/Twitter
Tesla's Model Y Hardware 4 infotainment system has been reviewed by one of the most notorious Tesla enthusiasts, and it's a surprising outcome. Following a series of tweets (or Xs) from renowned Tesla hacker @greentheonly, it has come to light that the HW4 unit sports less RAM and storage than its predecessor, Hardware 3 on the infotainment side (MCU).
This change doesn't seem to make much sense, given Tesla's track record of continuously improving the product. It has sparked a debate about the potential impacts and motivations behind the change.
HW4 vs HW3: A Comparison
The latest information revealed that the HW4 infotainment system in the Model Y comes with 8GB of RAM and 128GB of storage, exactly half of what the HW3 units offer. This significant reduction has led to questions about the possible implications on user experience, including the inability to support gaming services like Steam, which requires 16GB of RAM on the Model S and X. It's certainly possible Tesla finds a way to run Stream on less RAM, but it's unlikely given that Steam is run in a virtual machine.
Interestingly, despite these changes, the Central Processing Unit (CPU) between HW3 and HW4 remains the same. Furthermore, @greentheonly, who did an in-depth breakdown of HW4 last month, confirmed that both HW3 and HW4's infotainment side using the Advanced Micro Devices (AMD) CPU is susceptible to voltage glitching attacks. The surge attacks were revealed by a group of hackers, who call themselves researchers, last week.
Impacts on Performance
While concerns about reduced specifications are valid, some users report that the HW4 Model Y is incredibly responsive. @greentheonly attributes this to the model's newness, free from accumulated unnecessary data known as "cruft."
Reasoning Behind the Change
The decision to reduce the RAM and storage in HW4 seems perplexing to some Tesla fans, leading to speculation about Tesla's rationale for this move. However, cost considerations could be at the core of this decision. These changes were identified in Model Y HW4 units manufactured in both the Texas and Fremont factories.
Community Reactions
Tesla's community has shown mixed responses to the revelations. Some express disappointment at an apparent downgrade, while others remain hopeful about the system's optimized performance despite the reduced specifications. The discussion on TX.com also raised questions about why the Model Y configuration does not follow the same hardware pattern as Model S/X and why there are no performance trims for Infotainment.
The new findings about Tesla's Model Y HW4 infotainment with reduced specifications may seem like a step back, but the actual impact on user experience remains to be seen.
Whether Tesla's engineers have found a way to enhance the system with reduced resources or if this move is driven solely by cost considerations will likely become more apparent with time and usage. The dialogue initiated by @greentheonly provides valuable insights, though, and will continue to be a focal point for those interested in understanding Tesla's evolving technology and strategic decisions.

Tesla has been improving its FSD features since introducing it in 2016
Tesla
Previously, the Tesla X account shared a video where FSD V12 appeared to consider a pedestrian’s hand gestures when navigating. Elon Musk also confirmed on X that hand gesture recognition would be improved in V12.4, and even better by V12.5.
Tesla has had plans for gesture recognition for many years, with Musk mentioning hand gesture recognition in 2021. FSD is supposed to be able to adapt to new and unique circumstances in a safe manner, whether following instructions from a police officer, or understanding the hand signals from a cyclist.
Boris Johnson and FSD
Boris Johnson, the ex-Prime Minister of the UK, recently got to experience FSD V12 in the crowded streets of LA, with his wife and child in the backseat. Tesla provided a vehicle and assistant for his self-driven experience through 5-road intersections, heavy traffic, and pedestrians.
At the end of about 45 minutes I feel like a driving test examiner – except that I want to tell the car that it has passed, with flying colours. -Boris Johnson
Gestures coming soon
Johnson had a single experience with hand gestures in his drive – being waved at a hotel. While the car didn’t recognize the gesture – even on FSD V12.3.6 – the Tesla official in the vehicle confirmed that “‘It doesn’t yet recognise that gesture, but we are fixing it for the next iteration. It should be done next month.”.
It’s not immediately clear whether the Tesla employee is referring to FSD v12.4, which is expected to start rolling out to the public later this week, or Tesla’s next major FSD release, V12.5. According to Musk, V12.5 is expected to handle much more complicated situations and even start vehicle-to-fleet communication.
Yeah, I wouldn’t count on this in 12.3.x, but 12.4 is a big improvement and 12.5 might nail it
When you’re tackling a problem like FSD, which has never been solved before, you sometimes have to pivot and realize there’s a better approach. That’s what Tesla has done with FSD and AI. Just a few years ago where people thought cars would need to be able to read signs to achieve autonomy, but with the latest approach, there’s no need to. As long as the vehicle has seen a specific sign before and has enough examples, it’s already trained on what humans do when such a sign is found. The same will be true for hand gestures, the vehicle won’t need to know what each hand gesture means, it’ll just recognize that when a current gesture is made, this is how the vehicle should react.
Tesla does this by feeding it millions of examples of very specific situations and AI recognizes patterns. This is an example where Tesla leverages fleet data. They can easily capture millions of examples of hand gestures and how humans reacted, and feed that to their AI training model.
As Tesla processes more video, FSD will continue to improve. Tesla is expected to spend $10 billion on AI this year alone, most of it going toward improving FSD.
Coming to Rivian vehicles over a software update is Google Cast and YouTube support, which will allow for seamless, high-quality content streaming to Rivian vehicles.
This is a big step forward for Rivian’s software integration, especially compared to Tesla, which has yet to integrate native apps or release the long-rumored Tesla native app store.
Google Cast
Google Cast is Google’s version of Apple AirPlay which is supported in a variety of audio and video streaming apps such as Netflix, Disney+, YouTube, and more. By using a supported app, a user will be able to cast content directly to Rivian’s main 15.6” center screen.
Like Casting to a TV or Smart Device at home, this will allow you to play, pause, or skip back and forth using the vehicle’s touchscreen. Google Casting automatically pauses when the vehicle shifts into Drive.
Native YouTube App
Alongside Google Cast, Rivian is also bringing a native YouTube app to vehicles, enabling users to access YouTube’s video and music library from anywhere with a data connection. These features will be integrated right into Rivian’s vehicle operating system, which means they will receive regular software updates, and not be reliant on browser-based capabilities.
Similar to casting content, YouTube content will also automatically pause when the vehicle is shifted into Drive.
Tesla Equivalents
For the time being, there is no way to AirPlay or Cast video from a phone or tablet to Tesla’s front or rear screens. However, for some apps such as YouTube, you can send the video URL to the vehicle and have it open the YouTube app to that video.
To do this, open the YouTube app and find a video. Once you’d like to share it with the vehicle you can tap on share. You’ll then need to share it with the Tesla app which will then send it to your vehicle. On iPhones this requires you to scroll to the right and tap on More, which brings up the native sharing screen and has the Tesla app.
However, this is far more limited than including AirPlay or Google Cast support which will work for practically and video, even personal videos in your photo library.
Elon Musk mentioned back in 2016 that Tesla would add mirroring of phone apps to the center screen, but that has yet to materialize. More recently Musk mentioned a native X App coming to Tesla vehicles.
Tesla Theater
Tesla Theater allows users to stream videos from various platforms, including YouTube, but these are web-based applications, with no native applications available. This leaves some marked limitations on usability.
Tesla most recently announced in their 2024.14 update that the browser will be able to be expanded to full-screen mode when parked, enabling more access to streaming services on the web. Meanwhile, Google Cast and Apple Airplay continue to remain highly requested features.
