New Nvidia system designed to power fully autonomous cars

Nvidia just announced plans for "Pegasus," its next-generation system for autonomous cars. Due out in the second half of next year, Pegasus is a license-plate sized computer that the chip giant says can process 320 trillion operations per second. That, Nvidia said, is the equivalent to a 100-server data center and — more importantly — enough to power a fully autonomous car.

Why it matters: Increasing raw compute power is just one of the hurdles to getting to fully self-driving cars into mass production. That said, such a boost in processing allows the cars to make more use within the vehicle, including real-time analysis and inference based on data from radar, lidar and optical sensors.

Current picture: Although companies are already testing fully autonomous vehicles, most are very rough prototypes. On the compute side, most of the cars today have multiple PCs or servers in the trunk consuming thousands of watts of power.

"This is the path to production," says Danny Shapiro, senior director for automotive at Nvidia.

The competition: Intel and Qualcomm are also pursuing a role in the autonomous car industry with each company having an area of strength, according to analyst Patrick Moorhead, president of Moor Insights and Strategy.

  • Nvidia has the early lead on the processing and machine learning side.
  • Intel recently acquired MobileEye, which is a leader in advanced driver assistance systems.
  • Qualcomm is doing well when it comes to modems and infotainment systems.

Yes, but: Nvidia's move is a big one, Moorhead says.

"It has been possible to have the required compute level in a datacenter and even filling the back of the car, but it sucked way too much power and was too large and took too much cooling to be an effective auto solution," he says.

Twitter: Trump's Minnesota tweet violated rules on violence

Twitter said Friday morning that a tweet from President Trump in which he threatened shooting in response to civil unrest in Minneapolis violated the company's rules. The company said it was leaving the tweet up in the public interest.

Why it matters: The move exacerbates tensions between Twitter and Trump over the company's authority to label or limit his speech and, conversely, the president's authority to dictate rules for a private company.

Trump threatens to "assume control" of Minneapolis over unrest

President Trump threatened via Twitter early Friday to send the national guard to Minneapolis following three days of massive demonstrations and unrest in the city over George Floyd, a black man who died in police custody this week.

Details: "I can’t stand back & watch this happen to a great American City, Minneapolis. A total lack of leadership. Either the very weak Radical Left Mayor, Jacob Frey, get his act together and bring the City under control, or I will send in the National Guard & get the job done right," Trump tweeted after a police station was torched by some protesters.

Cheering protesters set a Minneapolis police station on fire Thursday night in the third night of unrest following the death of George Floyd, a black man who died in police custody in the city, per AP.

The state of play: Minnesota's governor on Thursday activated the state's national guard following violent outbreaks throughout the week, as the nation waits to see if the officers involved will be charged with murder.
