The creative and talented team over at Munro Live has shared some exciting new information about Tesla’s highly anticipated HW4.
Last month, Tesla hacker and owner Greentheonly leaked photos of the HW4 computer, citing a myriad of new features and improvements. The new computer will allegedly be 2-4x faster than HW3. A portion of this computing power will likely go toward processing additional data from the upgraded 5MP cameras.
Along with the upgraded 5MP cameras come some additional changes that make it hard for Tesla to retrofit HW4 into previous vehicles. The layout of the HW is quite different and, as noted in Munro Live’s video, the board is significantly larger, among other things.
The Power of Tesla
One thing in particular the Munro & Associates team uncovered was that Tesla removed the separate graphics card and integrated it directly onto the MCU circuit board. The Munro team said this would increase performance by removing the communication bottleneck between the two boards. Furthermore, this integration will save Tesla around $2 per vehicle due to removing some small parts and it will help streamline manufacturing.
Not Only for Cost Savings
This speaks volumes about the power and manufacturing abilities of Tesla. While $2 per vehicle isn't a big deal on its own, the cost savings alone, which are expected to be up to 4 million dollars this year, will more than pay for the engineering time spent on making these changes. However, the bigger win will come in having fewer parts to handle and assemble when building a vehicle. It will also help increase the vehicle's reliability by having fewer failure points.
The AMD-powered infotainment processor is unchanged in HW4, but the processor utilized for taking the input from the cameras and sensors is now larger and received a performance boost. Tesla is expected to transition all vehicles to hardware 4 this year, including the upcoming Cybertruck (new Cybertruck features uncovered at Investor Day)which is expected to begin manufacturing this summer.
