He added 11 points for Team USA in just 21 minutes, surpassing Lisa Leslie's tally of 488 to make him the top-scorer of any American basketball player, male or female, at the Games.
Joel Embiid, greeted by a chorus of boos from the French fans after passing on the chance to play for their national team, was the star though, as he got 14 points and seven rebounds in the first half to set the USA on their way to victory.
LeBron James also orchestrated the game, for 12 minutes at least, making snapshot passes as he piled up nine assists and 12 points. However, his game came to an early end when he took an elbow to the face from Georginho De Paula.
Devin Booker top scored for the USA with 18 points as they shared the load, and though Bruno Caboclo got 24 points for Brazil, he could not inspire a shock upset against the reigning champions.
Steve Kerr's team are chasing a fifth consecutive gold medal but will have to face Serbia, who they beat in their competition opener, for a place in the final.
Embiid, who was born in Cameroon but was granted US citizenship in 2022, declared for Team USA late last year after his home country failed to qualify.
That decision came after he also sought French citizenship, amid suggestions president Emmanuel Macron had called the Philadelphia 76ers star to convince him to represent the hosts.
Embiid has been jeered by French fans throughout the basketball tournament, with the USA winning all five of their games to date, reaching the final with Thursday's comeback victory over Serbia.
On the eve of Saturday's gold medal match, Embiid said: "Frankly, I don't understand why I've gotten a lot of criticism from the crowd.
"They're going to boo me. I'm going to go back at them and tell them to 'suck it.' It's going to be fun."
Reflecting on his decision to link up with LeBron James, Stephen Curry and company in representing the USA, Embiid said he would have played for Cameroon if they had qualified.
"Having lived half of my life in the US and the other half in my country, Cameroon, it just looked like it was, 'you could go two ways'," Embiid said.
"I said from the beginning that if Cameroon would've qualified, that would never have been a choice. Then having the family [in the US] and having built a lot of things and having accomplished a lot of things, knowing the group of guys deeply, it just made it easy.
"I think a lot of people wanted to make it an issue because of the storyline and all that stuff.
"But to me it's whatever it takes to win gold. So that's what I'm focused on. It's all about Team USA against France."
Embiid and Davis have both been suffering from illness in recent days while Durant – Team USA's all-time record points scorer at the Olympics – missed their five warm-up games with a calf injury.
As the United States prepare to take on NBA MVP Nikola Jokic in their opening Group C game, coach Steve Kerr will give his stars every chance to prove their fitness.
"I'm confident we'll have everybody ready," Kerr said on Saturday.
Asked specifically about Durant's condition, Kerr added: "Hopefully he'll play.
"He came through the scrimmage two days ago pretty well, and we'll have another practice today and just keep taking it day by day."
The USA did beat Serbia 105-79 in an exhibition game in Abu Dhabi earlier this month, also overcoming Jokic and company in the gold medal match at Rio 2016.
The Denver Nuggets star averaged 26.4 points through 79 regular season games in 2023-24, only managing more in his second MVP campaign in 2021-22 (27.1).
Los Angeles Lakers forward Davis is wary of the threat he will pose to the USA's chances of starting with a win, as they target a fifth straight gold in the men's basketball competition.
"Jokic, with what he's able to do, obviously we know what he does in the NBA, but maybe he'll get a little bit higher usage in the international game," Davis said. "It's going to be fun."
The NBA's all-time leading scorer LeBron James, who helped his country win gold at Beijing 2008 and London 2012, is aware a fast start to their campaign could make all the difference.
"This is not like the NBA, where it's a marathon," James said. "This is a sprint.
"This is a Michael Johnson or Usain Bolt-type game. The real thing starts tomorrow, so we need to be ready to go, which we will be."
Team USA stayed perfect by beating Puerto Rico 104-83 on Saturday, ensuring they sealed the top seed for the last eight.
That means the four-time reigning Olympic champions will take on the seventh seed, Brazil, for a place in the semi-finals.
Anthony Edwards led the USA with 26 points, while Joel Embiid chipped in with 15 and Kevin Durant delivered another fine substitute performance, scoring 11 points from the bench.
And while the USA have tallied up 317 points in their three wins so far, Kerr believes there is much more to come.
"I think we got done what we wanted to accomplish, winning all three games and securing the top seed," said Kerr.
"We know we have to play better. Part of this tournament is it gets harder as you go."
LeBron James added 10 points for the star-studded USA, and he knows it is now do-or-die.
"We know it's going to be difficult, it's going to be challenging," he said. "We better be ready to go."
In Group C's other game, Nikola Jokic scored 22 points and finished with 13 rebounds, while Bogdan Bogdanovic had 28 points, as Serbia saw off South Sudan 96-85.
While Serbia clinched the fourth seed to set up a meeting with Australia, South Sudan's inaugural Olympics campaign is over, with Greece scraping in as one of the two best third-placed teams.
Giannis Antetokounmpo's team will take on second seed Germany, who like the USA, won their three group games.
