Tesla's upgraded infotainment system powered by AMD Ryzen CPUs negatively impacts the range of the Model 3 and others

[Redaktion]

More performance sometimes results in a higher power consumption, which is why Tesla had to inform certain customers that the projected range of their ordered Model 3 is lower due to the recently introduced AMD Ryzen CPUs which now power Tesla's infotainment systems.

That just does not sound right.

Actually it does make sense as Intel Atom was replaced by actual CPU , consuming more power.

The Tesla 3 has a 82 kWHr battery. 3.6% of that over a 6 hour trip works out to nearly 500 watts each hour. Do you really think a Navi 23 GPU is drawing 500W when nearly idle? It beggars belief.

I wonder if older cars can update to this CPU, I've always been an AMD fan boy even when they were the worst

It's not nessesarily a 6 hour battery drawdown, that's a best case scenario for tiny APU wattage. They have to quote a worst case scenario for impacting range.
The infotainment system may be running 90 hours between charges. If someone is stuck in traffic each day. What's the 'dog' mode for people leaving dogs in their Tesla while they leave the car, that leaves the infotainment turned on... Or all the idle car monitoring subsystems, are those running on this hardware? That's significantly more APU/system power drain that would affect vehicles that are charged less frequently.

This article was paid for by Intel. They just mad. Any upgrade from an Intel atom(trash chip) will consume more power. Even if it was a better Intel chip. The fact is you get better performance per watt with an amd chip.
