News on November 10 The well-known whistleblower "German Pikachu" @Patrick Shur broke the news that he obtained an internal AMD document showing that AMD's Big Navi architecture new generation Navi 23 core GPU will be used for Tesla. In order not to reveal the identity of the leaker, the tweeter later deleted some information about the data map stamped by Tesla.
Current Tesla cars use Nvidia graphics processors as part of the hardware for autonomous vehicles. Earlier, Tesla also used a visual recognition chip made by Israeli technology company Mobileye. Later, Intel bought Mobileye for $15 billion. It is worth noting that Tesla does not have a cooperative relationship with Intel. In fact, Intel has maintained a long-term cooperation with Waymo car group, an autonomous driving technology company under Google's parent company Alphabet.
Nvidia's image processor is widely used in the field of artificial intelligence, but its wide range of uses is not limited to some simple computing tasks, so custom chips have been developed. Tesla first used the Nvidia Tegra chip in its MCU controller; later, Tesla switched to its own chip and launched Fully Automatic Driving (FSD); later, with the introduction of Autopilot, Tesla Turned to Intel chips. And now it seems that it may be AMD's turn.
More details about AMD’s new generation of Navi 23 and Tesla vehicles are currently unknown, but in any case, Tesla’s current direction must be true fully automatic/unmanned driving functions, so visual recognition calculations are In a very important area, graphics cards are relatively more advantageous in this regard, and support parallel processing and are cost-effective. Tesla has no reason not to use better and cheaper chips.
Regarding the computing power of the Big Navi architecture, you can see a glimpse of the game performance. AMD previously stated: Compared with AMD RDNA-based graphics cards, the AMD RDNA2 architecture can provide up to 2 times the game performance, and the performance per watt can be increased by 54%.
