Everyone has been talking about Tesla's latest hardware (HW4) for a few months now. Tesla has been equipping the new Model S/X with the new technology as the first models since March of this year. But now we get a closer look at the new HW4 infotainment system of a Tesla Model Y with surprising results. From a series of "tweets" from the well-known "Greentheonly," it appears that the HW4 unit has less RAM and memory on the infotainment side (MCU) than the HW3. This change has sparked a real debate about the possible effects and the motives for this change.
It became clear that the HW4 system in the Model Y equipped with 8 GB of RAM and 128 GB of storage, which is exactly half of the HW3 systems. This reduction has raised questions about the potential impact on usage, including the inability to support services like Steam, which require 16 GB of RAM on the S/X models. Interestingly, despite these changes, the central processing unit (CPU) remains the same between HW3 and HW4. Although concerns about the reduced specs are justified, some users report that the HW4 is Model Y is incredibly responsive. "Greentheonly" attributes this to the novelty of the model, which is free of accumulated unnecessary data.
Hm, looks like model Y hw4 infotainment side is somewhat crippled compared to hw3 units:

it has half as much RAM and half as much storage (8G and 128G respectively).
Given current requirements for steam, that crosses steam out (Even though not officially supported anyway).
The decision to reduce the RAM and storage capacity of the HW4 may seem puzzling, leading to speculation about Tesla's reasons for this move. However, it is possible that cost savings were the reason for this decision. The changes were made in Model Y HW4 units that were manufactured in both Texas and Fremont. Reactions from the Tesla community to the revelations have been mixed. Some expressed disappointment at the apparent degradation, while others were hopeful about the system's optimized performance despite the reduced specifications. The new findings about the Tesla Model Y HW4 infotainment with reduced specifications may seem like a step backward, but the actual impact remains to be seen. Time and usage will tell if Tesla engineers have found a way to improve the system with fewer resources, or if this move is driven solely by cost considerations.
