Nvidia wants to be the brains of your self-driving car
What is happening
Tesla has unveiled a new processor called Thor designed for cars arriving in 2025 that need far more computing power than they have today.
why is it important
Thor could help automakers sweep away a host of smaller processors handling everything from door locks, braking, navigation, entertainment and engine control with a centralized computer system that’s easier to update.
Chip designer Nvidia on Tuesday unveiled a new processor called Drive Thor that it says will power the autonomous vehicle revolution.
Thor processors are expected to arrive in 2024 for cars hitting the road in 2025, starting with Chinese automaker Zeekr‘s 001 EV, said Danny Shapiro, vice president of automotive work at Nvidia. They are based on to better manage the artificial intelligence software that is key to self-driving cars.
“It will absolutely transition to full autonomy,” Shapiro said, referring to Level 4 or 5 autonomous driving capabilities, in which cars can steer themselves without human occupants paying attention or even being present.
Nvidia had planned afor 2024 but canceled it in favor of Thor, which runs the AI software at 2 quadrillion operations per second – twice the speed Atlan’s intended and eight times that of its current Orin processor. Thor incorporates a key feature of Hopper: the ability to accelerate a powerful AI technique called Transformers. Nvidia also expects lower-end Thor variations for less game-changing driver-assist technologies like lane-keeping and automatic emergency braking.
The market for automotive processors is large and growing as automakers increasingly require processors and other semiconductor chips for driver assistance, infotainment, and electronic control units that oversee everything from engine combustion to GPS navigation. Each Porsche Taycan has 8,000 semiconductor elements.
Also new to Nvidia’s GTC
Among other developments from Nvidia at its GTC event:
- His gaming PCs and workstations, will go on sale in October at prices ranging from $899 to $1,599. powered by its next-generation Ada Lovelace GPU for
- The Jetson Orin range of processors for robots now includes Nano models for smaller robots. They draw between 5 and 15 watts of power for better battery life, cost $199+, and start shipping in January. Recently announced companies using Jetson Orin include Canon, John Deere, Microsoft Azure, Teradyne and TK Elevator, Nvidia said.
- New Nemo LLM technology is designed to help researchers make better use of large language models, a hot new area of AI that is responsible for rapid advances in processing language, imagery and other data . Retraining an LLM consumes massive resources, but Nemo technology allows researchers to perform much faster incremental AI training that personalizes big AI.
Thor Automotive AI Chip Details
With 77 billion transistors, Thor will be massive, if not the biggest processor on the market. But it will allow automakers to replace a collection of smaller, heavier, more expensive and power-hungry chips, according to Nvidia. In addition to using Hopper GPUs, it borrows CPU cores fromfor typical computing tasks. It also draws technology from Nvidia’s newest GPU technology for gaming and design, the Ada Lovelace Architecture.
The design will make it easier for automakers to improve their automotive software with over-the-air updates, Huang said. Tesla has had a great technological lead in this technology for years.
Thor will also be used for robots and medical equipment, Huang said. And it will be able to simultaneously run three operating systems – Linux, QNX and Android – for different parts of the automotive computing environment. The partitioning technology ensures that less important jobs, like infotainment, don’t interrupt security-critical jobs, Nvidia said.
With autonomous vehicles, promised for years but still only in testing, these chips become even more important.
“The industry has recognized that it’s a much more complex task than initially thought,” Shapiro said of self-driving vehicles. “With safety being paramount, no one is ready to release these vehicles into the wild until there is more reckoning.”
