AMD says nothing about HW3 or HW4
The two lines are independent. Read both before you compare feature lists.

Intel or AMD? HW3 or HW4? Check your Tesla’s computers
Your Tesla has two computers that decide different features. Where to read both in the car, and which recent features need which.
Short answer
Every recent Tesla has two separate computers. The infotainment computer (AMD or Intel) runs the screen, apps, Toybox and Grok. The driving computer (HW3/AI3 or HW4/AI4) runs the cameras, Autopilot and FSD. Read both under Controls › Software › Additional Vehicle Information. They are independent: an AMD car can still have HW3, which is why so many feature lists say “AMD and HW3” or “HW4 only”.
Two computers, two questions
Where to look
WhereControls›Software›Additional Vehicle Information
- Infotainment lineNote the processor exactly as shown: AMD or Intel. Tesla documents this path for checking Grok eligibility.
- Driving computer lineNote the Autopilot or driving-computer entry separately. Tesla’s 2022 service bulletin shows these as two fields.
- Full versionWrite down the complete build from the Software screen, not just the branch.
Easy to miss
Do not guess from the delivery year or the outside of the car. Some years were built with either computer.
Which recent features need which
| Feature | Needs | Since |
|---|---|---|

| Caraoke with scoring | AMD | 2026.26 |
| Dashcam viewer zoom | AMD | earlier |

| FSD (Supervised) v14.3 Lite | HW3 | 2026.33–38 (N. America) |
Good to know
Intel cars still get new things
In 2026.38, Intel-era cars got Supercharger site maps, and Intel Model S and X got FSD v14.3 Lite for the first time.
HW3’s FSD future is “Lite”
Several outlets expect v14 Lite to be the last big FSD generation for HW3. Tesla has not confirmed that.
Keep a small compatibility note
- Model and generation
- Country where you use the car
- Full installed version
- Infotainment and driving-computer lines, separately
- Tesla app version, when a feature needs it
Keep it in your own notes. This website never asks for your VIN or connects to your Tesla account.
Questions
How do I know if my Tesla has HW3 or HW4?
Open Controls › Software › Additional Vehicle Information and read the driving-computer (Autopilot computer) line. Do not go by the delivery year alone.
Is AMD the same as HW4?
No. AMD is the infotainment computer; HW3 and HW4 are driving-computer generations. A car can have AMD with HW3.
Why does my Tesla not have Grok?
Grok needs the AMD infotainment computer and Premium Connectivity or Wi-Fi, and is only offered in some countries.

Summaries in our own words, not Tesla’s release notes. Features depend on model, hardware, market and software version; the notes in your car take precedence.
