A teardown and description of Tesla’s upcoming Hardware 4 (HW4) pc has leaked on-line revealing improved Exynos SoCs, added digital camera connectors, and references to the brand new Phoenix radar. A brand new infotainment board that features a customized AMD CPU and AMD GPU can be seen. The HW4 sports activities a totally completely different kind issue, which suggests it can’t be retrofitted into current Tesla cars.
Tesla is anticipated to improve its self-driving pc to the Hardware 4.0 (HW4) model from the current HW3. While issues are nonetheless formally underneath wraps, photographs of HW4 and possible adjustments coming to Tesla’s Full Self-Driving (FSD) have leaked on-line.
From what we all know up to now, Telsa is upgrading its computing platform to accommodate improved radar and digital camera techniques. Known Tesla leaker @greentheonly on Twitter has posted visuals of the HW4 pc in a thread.
The OP managed to put fingers on a HW4 pc from an upcoming Model X. Thus, it’s seemingly that the automaker will likely be liquidating its current Model X manufacturing and quickly launch a brand new collection with HW4 {hardware}.
Coming to the {hardware} itself, @greentheonly‘s teardown reveals that Tesla will no longer provide a separate daughter board for the GPU. Instead, the AMD CPU, AMD GPU, 256 GB NVMe, and 16 GB RAM will all be current on the identical infotainment board.
The HW4 {hardware} continues to be primarily based on a Samsung Exynos chip. The CPU cores are actually elevated from 12 to twenty (5x 4-core clusters). These cores can enhance as much as 2.35 GHz and idle at 1.37 GHz, in accordance with the OP. An further TRIP core (whole of three cores) in every TRIP unit on each the SoCs is current with a most frequency of two.2 GHz. The TRIP cores are principally those that deal with neural internet computations.
HW4 appears to be working the Linux kernel 5.4.161-rt67. As is essential in self-driving autos, the HW4 options redundancy with similar energy connections on either side and two community hyperlinks to the infotainment board. However, the OP notes that killing energy to the A aspect kills the community swap and the connection is misplaced altogether.
There are actually 12 digital camera sensors (somewhat, connectors) on HW4 together with one marked “Spare”, which is a rise from the eight connectors we have seen with HW3.
The digital camera placement can even change — the aspect cameras will now be positioned in the entrance fenders whereas two can be positioned in the windshield. Tesla cars that includes HW4 would keep away from possible blind spots by inserting cameras in entrance and rear bumpers as effectively.
HW4 will make use of a brand new radar module referred to as Phoenix, references to that are discovered in the firmware. According to Tesla, Phoenix is a non-pulsed automotive radar that works in the 76-77 GHz frequency vary and helps three sensing modes.
The Federal Communications Commission (FCC) has launched photos and documentation for Phoenix, which have been accessed by Teslarati. A brand new tri-band GPS module is current as effectively.
@greentheonly additionally notes that the idle energy consumption with HW4 is kind of larger in comparison with HW3.
Bad information for current Tesla house owners
While the adjustments coming to HW4 are welcome, Elon Musk has formally killed any hopes for current Tesla house owners eager to retrofit HW4 into their cars. In a This autumn 2022 convention name, Musk stated that it’s not economically and technically possible to retrofit Hardware 3 with Hardware 4.
However, he did affirm that HW3 will “still exceed the safety of the average human” and that it’ll obtain its full self-driving (FSD) objectives.
@greentheonly additionally confirmed that it’s not possible to retrofit HW4 into HW3 cars given the utterly completely different kind components between the 2 modules. While new premium Tesla fashions will include HW4 put in, the OP appears fairly certain that new Model 3 cars can even get the brand new smarts finally.
It just isn’t recognized when Tesla would make the HW4 official, however the firm’s Investor Day on March 1 appears to be a possible date.
