According to an EET analyst report, Apple Car will be using an automotive-grade chip temporarily named C1 based on the current A12 Bionic processor and will be manufactured with the 7nm process partnering TSMC.
Features include a 4-core GPU, in-cabin AI eye-tracking ability.
The A12 Bionic is manufactured by TSMC with 7nm FinFET process. It contains 6.9 billion transistors using up 3.5W energy.
It has a better performance compared to the current in-house designed FSD computer chips used for Tesla, which contains 6 billion transistors consuming 36W energy, manufactured by Samsung with 14nm process.
In a provisional stage for gradually achieving a full self-driving mode, the Tesla FSD chip was unveiled in 2019, the company claims it performs more than 20 times better than the previous NVidia chips and it is currently applied in Tesla’s Model S, Model X and Model 3.
Tesla moving to 5nm process with current partner Samsung
According to the Electrek, citing a translated Korean report by AsiaE, Tesla is partnering Samsung on moving onto developing 5nm FSD computer chip, skipping the 7nm stage. Mass production is slated at the end of 2021.
According to the same source, the high-tech extreme ultraviolet (EUV) will be applied to the chip. Automotive computers will likely be carrying them earliest in 2022.
Samsung and TSMC have both worked into the 5nm process which only came into volume shipment by the end of last year.
The Apple A14 Bionic carried in iPhone 12 was the first 5nm chip applied in a commercial product manufactured by TSMC and are only found in some of the new smartphones, among which Samsung is also producing its own 5nm Exynos chipsets.
