Tesla to use AMD Navi 23 GPU for its infotainment system?
A diagram showing AMD Navi 23 GPU connection with Tesla onboard systems has leaked.
Known leaker Patrick Schur posted a diagram, which appears to confirm that Tesla will be using AMD Navi 23 GPU for its onboard entertainment and (possibly) navigation systems. The diagram would confirm that Navi 23 for Tesla systems will have GDDR6 memory in 16Gb (2GB) capacity. This memory would be manufactured by Samsung (K4ZAF325XM). There would be 4 modules which means 8GB of memory in total. According to the diagram, the memory is 14 Gbps and is attached to a 128-bit memory bus. This would provide a maximum bandwidth of 224 GB/s, similar to Xbox Series S.
The system offers dual DisplayPort and HDMI 1.4 connections along with PCIe Gen4 x8 (8Gb/s) which are attached to onboard monitors and board to board (B2B) connector.

According to Tesla, the new system will offer up to 10 teraflops of power, which is comparable to the Sony PlayStation 5. In order to achieve such a FP32 compute power, 32 Compute Units of Navi 23 GPU (2048 Stream Processors) would have to be clocked at least 2.44 GHz.
