Optimerad kod för HW3 lanseras snart.
Dock kan det innebära att HW2 och HW2,5 inte uppdateras mera.

What this likely means is that Tesla pretty much just took the existing Autopilot software designed for HW2 and emulated it to run on HW3. Now, for those of you unfamiliar with emulation, a good explanation is the movie Inception, but for computers. Imagine a Windows 10 computer running the Android operating system in a window — basically, Android is a program on the computer, not the operating system.
In this case, HW3 emulated HW2 to get the existing Autopilot software to function. The only problem is, HW3 is supposed to run most tasks not on the processor or graphics card but on its Neural Processing Units (NPUs), which are not designed for direct software emulation and are probably not capable of that. In principle, the Graphics Processing Unit (GPU) and the Central Processing Unit (CPU) together are capable of emulation. However, the CPU and GPU components of HW3 are less powerful than the ones in HW2, so they physically cannot directly emulate it. So, Tesla did move some tasks to the NPUs to make it work — but Autopilot needed a major rewrite of the base code to truly unlock HW3’s potential.
Thanks to Third Row Podcast’s interview with Elon Musk, we now have confirmation of the above theory and some really juicy new details. All these months, Tesla was rewriting Autopilot’s base code behind the scenes and will soon(ish) push that update to all vehicles running HW3. This could even signal the end to major updates for HW2 and HW2.5 Autopilot systems.
