Tesla relies on AMD hardware to power the infotainment system on current Plaid versions of its Model S and Model X electric cars. Which one is exactly, he recently revealed to the Youtube channel “Ingineerix”, which unpacked the motherboard module and showed the individual chipsets.
While a standalone graphics card with a Navi-23 GPU and an FP32 processing power of about 10 TFlops is one of the newer things you can get, the processor has been behind it for a few years. It bears model number YE180FC3T4MFG, which speaks of an offshoot of AMD’s first generation Zen Ryzen Embedded V1807B. The packaging structure with the distinctive metal frame and the elongated silicone chip indicated under the thermal paste supports the premise.

The YE180FC3T4MFG uses four Zen 1 cores with eight threads and an integrated Vega graphics unit with up to 11 CUs or 704 shaders. According to AMD’s June 2021 announcement, the GPU of a composite processor is used when the 3D load is low; And the big graphics card Navi-23 takes care of the games.
8 GB GDDR6-RAM
AMD uses the Navi-23 GPU in desktop computers such as the Radeon RX 6600 XT and Radeon RX 6600 with 32 and 28 compute units respectively, that is, a maximum of 2048 shader cores. Meanwhile, four memory modules bearing the label K4ZAF325BM can be seen on the graphics card Compatible with a total of 8GB GDDR6 RAM. It is not clear whether it is an HC14 or an HC16 unit. Based on this, the memory achieves a transfer rate of 224 or 256 GB / s on 128 data lines. In the case of main memory, the label on the four slides is not visible.
The bottom line is that Tesla’s infotainment system is the fastest of its kind and almost comparable to Sony’s Playstation 5 game console. It is not for nothing that Tesla advertises games for passengers – the advertising images prominently show the role-playing game “The Witcher 3”.
