Navi-23-Tesla-Diagram-1200x704.jpg

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....

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..

Backs up reports of secondary board in addition to the Intel Atom based MCU2.

So the CPU is likely AMD too.

Now it would've been great if they partnered up with Steam/Epic and let people play games they already own... assuming they'd be able run Linux ports.

Speak to me like a 3rd grader - is that a good processor?
It is the latest, fastest graphics processor (GPU). The kind the new XBox and PlayStation have. According to Reddit the main processor (CPU) is the same automotive grade Intel Atom as in MCU2 but in the new S/X the two are wired over a network like the autopilot computer is.

I wouldn't go as far as to say its the fastest GPU, its a mid range GPU, not a high end GPU. For AMD that would be Navi 21.
Agreed. Maybe I should have said most efficient, since you fastest can always be achieved with more cores and more power consumption, generating more heat. But the requirement was language for a third grader and not all third graders know what efficient means.

That said, if I were Tesla, I would be putting resources into VR gaming with that hardware. Not sure you are any more apt to get car sick with a VR headset than you are looking at a tiny screen attached to the console.
