Tesla self-driving Hardware 4 (HW4) teardown from upcoming Model X reveals significant upgrades and consolidated AMD CPU-GPU infotainment board, no retrofit possible in current Tesla cars

Tesla is expected to up grade its self-driving laptop to the Hardware 4. (HW4) model from the existing HW3. Though items are nonetheless formally beneath wraps, photographs of HW4 and doable improvements coming to Tesla’s Comprehensive Self-Driving (FSD) have leaked on-line.&#13

From what we know so considerably, Telsa is upgrading its computing platform to accommodate enhanced radar and camera devices. Recognized Tesla leaker @greentheonly on Twitter has posted visuals of the HW4 laptop or computer in a thread.&#13

The OP managed to lay arms on a HW4 laptop or computer from an forthcoming Model X. Therefore, it is most likely that the automaker will be liquidating its existing Product X generation and shortly launch a new collection with HW4 components.&#13

Coming to the components by itself, @greentheonly‘s teardown reveals that Tesla will no for a longer time offer you a different daughter board for the GPU. Instead, the AMD CPU, AMD GPU, 256 GB NVMe, and 16 GB RAM will all be existing on the exact infotainment board. &#13

The HW4 components proceeds to be centered on a Samsung Exynos chip. The CPU cores are now elevated from 12 to 20 (5x 4-core clusters). These cores can boost up to 2.35 GHz and idle at 1.37 GHz, in accordance to the OP. An supplemental Trip core (whole of 3 cores) in each Journey device on both of those the SoCs is existing with a utmost frequency of 2.2 GHz. The Trip cores are fundamentally the types that deal with neural internet computations.&#13

HW4 looks to be running the Linux kernel 5.4.161-rt67. As is essential in self-driving autos, the HW4 attributes redundancy with identical electrical power connections on every side and two network backlinks to the infotainment board. Even so, the OP notes that killing electricity to the A aspect kills the community switch and the link is lost entirely.&#13

There are now 12 digicam sensors (relatively, connectors) on HW4 which includes a single marked “Spare”, which is an improve from the eight connectors we’ve seen with HW3.

The digicam placement will also improve — the side cameras will now be placed in the front fenders although two would be placed in the windshield. Tesla autos that includes HW4 would avoid doable blind places by putting cameras in front and rear bumpers as perfectly. &#13

HW4 will make use of a new radar module identified as Phoenix, references to which are located in the firmware. According to Tesla, Phoenix is a non-pulsed automotive radar that operates in the 76-77 GHz frequency vary and supports a few sensing modes. &#13

The Federal Communications Fee (FCC) has produced photographs and documentation for Phoenix, which have been accessed by Teslarati. A new tri-band GPS module is present as very well.&#13

@greentheonly also notes that the idle electric power use with HW4 is really greater when compared to HW3.&#13

Bad news for latest Tesla entrepreneurs

When the changes coming to HW4 are welcome, Elon Musk has formally killed any hopes for recent Tesla homeowners seeking to retrofit HW4 into their cars and trucks. In a Q4 2022 meeting call, Musk mentioned that it is not economically and technically possible to retrofit Components 3 with Hardware 4. &#13

However, he did verify that HW3 will “continue to exceed the safety of the normal human” and that it will reach its total self-driving (FSD) ambitions.&#13

@greentheonly also verified that it is not achievable to retrofit HW4 into HW3 automobiles provided the wholly distinctive form things involving the two modules. Even though new top quality Tesla types will come with HW4 set up, the OP appears pretty positive that new Product 3 cars and trucks will also get the new smarts sooner or later.&#13

It is not recognised when Tesla would make the HW4 formal, but the company’s Investor Day on March 1 would seem to be a possible date.&#13
