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

North America is finally getting its new 2022 Tesla Model Y and Model 3 batches with upgraded media system processors and new 12V batteries. Tesla is now equipping all new cars with AMD Ryzen chips instead of the older, slower Intel Atoms, and swapping the 12V lead-acid batteries that were prone to failure with new Li-ion packs. Previously, the AMD Ryzen advantage was only given to Tesla cars made in its Chinese factory, but now the goods are coming to America.

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.

Wooed by tech since the industrial espionage of Apple computers and the times of pixelized Nintendos, Daniel went and opened a gaming club when personal computers and consoles were still an expensive rarity. Nowadays, fascination is not with specs and speed but rather the lifestyle that computers in our pocket, house, and car have shoehorned us in, from the infinite scroll and the privacy hazards to authenticating every bit and move of our existence.
