Tesla goes AMD Ryzen for the 2022 Model Y and Model 3 infotainment systems in America, gets rid of 12V lead-acid batteries

Tesla has begun to equip the 2022 Model Y and Model 3 models that are rolling off the conveyor belts in the U.S. as we speak with new AMD Ryzen processors and replacing their old-school lead-acid 12V batteries with modern Li-ion ones. Previously, the AMD Ryzen chipset privilege was only reserved for the infotainment systems installed in the fresh Model S and Model X, as well as the Model Y Performance cars that were produced in Tesla's China factory.

The move from the slow Intel Atom A3950 processor to a new Ryzen already proved to be the best thing that has happened to Tesla's in-car media system for a while, and now the goods are coming to US shores as well. You can see the AMD Ryzen vs Intel Atom performance on a Tesla in the video below and witness the end of stuttering or app load waits.

The lead-acid battery swap for a Li-ion one is also a small but very important under-the-hood change for Tesla owners. Older Tesla models are equipped with a 12V battery that is prone to giving up the ghost way too quickly for a modern battery-powered vehicle. Tesla even issued a software update trying to resolve the power drain issues that left your lead-acid 12V battery for dead and your windows and media system not working as a consequence.
