Apple pulls the plug on its high-priced, oft-neglected Mac Pro desktop

fivenewscrypto    mars 29, 2026   

After more than a decade of flirting with the idea, Apple has finally discontinued the Mac Pro tower. The company confirmed to 9to5Mac that the latest Mac Pro iteration—an M2 Ultra model first released in mid-2023—would be its last, at least for the time being. There are no plans to make another Mac Pro.

The discontinuation of the Mac Pro should come as no surprise to anyone who has been paying attention. Reporting from late last year suggested that the Mac Pro had been put "on the back burner," but the desktop has clearly been in danger of falling off the stove since at least the mid-2010s, during the six-year period where the controversial cylindrical "trash can" Mac Pro design languished without updates.

Apple briefly rededicated itself to its pro desktop in 2019 with a new design that hearkened back to more versatile, upgradeable, be-handled versions of the Power Mac and Mac Pro. But by the time it was updated again with M2 Ultra four years later, it was already clear that the idea of a huge and expandable Mac desktop was out of step with the Apple Silicon era. The desktop's demise confirms that, at least in Apple's estimation, the Mac Pro was trying to fill a niche that no longer exists.

Rivian and VW Group complete winter testing of new zonal architecture

Rivian and VW Group complete winter testing of new zonal architecture

fivenewscrypto    mars 29, 2026   

RV Tech, a joint venture between Volkswagen Group and Rivian, has completed a successful winter test program, it said this morning. The partnership was created in 2024 when VW Group announced it would invest $5.8 billion in the American electric vehicle maker to gain access to Rivian's expertise in vehicle software and electronic architecture. VW Group initially paid Rivian $1 billion in cash, with further payments over time: the completion of the winter testing milestone should unlock a further $1 billion payment.

VW's decision to turn to Rivian followed a tortuous history of its own internal software development. It created a new division in 2019 just to develop software for cars, then immediately bit off more than it could chew by trying to simultaneously develop three different vehicle operating systems. Things went the opposite of smoothly, with software-related delays to the two new platforms used by cars like the VW ID.4 and Porsche Macan that led to chairman Herbert Diess' firing and the third platform delayed until late in this decade.

Rivian, meanwhile, had no such problems developing its own vehicle electronic architecture and software, starting from a clean sheet unencumbered by generations of legacy cruft. As a startup automaker, Rivian needs money, and since Volkswagen needs better tech, the joint venture makes a lot of sense.

Senators want US energy information agency to monitor data center electricity usage

Senators want US energy information agency to monitor data center electricity usage

fivenewscrypto    mars 29, 2026   

Democratic Senator Elizabeth Warren and Republican Senator Josh Hawley are urging the US’s central energy information agency to provide better information on how much electricity data centers actually use.

In a joint letter sent to the Energy Information Administration Thursday morning, seen by WIRED, Hawley and Warren press the agency to publicly collect “comprehensive, annual energy-use disclosures” on data centers. This information, they write, is “essential for accurate grid planning and will support policymaking to prevent large companies from increasing electricity costs for American families.”

As the data center boom spreads across the country, there have been widespread worries from voters about how their massive energy needs may increase consumers’ electric bills; this concern helped shape some midterm elections in data-center-heavy states, including Virginia and Georgia. Last month, Hawley cosponsored a bill with Democratic Senator Richard Blumenthal that would require data centers to supply their own power sources in order to protect consumers. Earlier this month, Donald Trump convened a group of executives from Big Tech companies at the White House to sign a nonbinding (and toothless) agreement pledging to pay for their own power for data centers.

AMD's Ryzen 9 9950X3D2 Dual Edition crams 208MB of cache into a single chip

AMD's Ryzen 9 9950X3D2 Dual Edition crams 208MB of cache into a single chip

fivenewscrypto    mars 28, 2026   

For about four years now, AMD has offered special "X3D" variants of its high-end desktop processors with an extra 64MB of L3 cache attached, an addition that disproportionately benefits games. AMD calls this "3D V-Cache" because it stacks the cache directly on top of (for Ryzen 5000 and 7000) or beneath (for Ryzen 9000) the CPU die.

The 12- and 16-core Ryzen chips have their CPU cores split between two silicon chiplets, which has historically made the 7900X3D, 7950X3D, 9900X3D, and 9950X3D a bit weird. One of their two CPU chiplets has the 64MB of 3D V-Cache attached, and one does not. AMD relies on its driver software to make sure that software that benefits from the extra cache is run on the V-Cache-enabled CPU cores, which usually works well but is occasionally error-prone.

Enter the Ryzen 9 9950X3D2 Dual Edition, a mouthful of a chip that includes 64MB of 3D V-Cache on both processor dies, without the hybrid arrangement that has defined the other chips up until now. This gives the chip a grand total of 208MB of cache—16MB of L2 cache, the 32MB of L3 cache built into each of the two CPU dies (for a total of 64MB), and then another 64MB chunk of 3D V-Cache per die. In total, AMD says the new chip should be as much as 10 percent faster than the 9950X3D in games and other apps that benefit from the extra cache.

Rocket Report: Russia reopens gateway to ISS; Cape Canaveral hosts missile test

Rocket Report: Russia reopens gateway to ISS; Cape Canaveral hosts missile test

fivenewscrypto    mars 28, 2026   

Welcome to Edition 8.35 of the Rocket Report! The headlines this week are again dominated by the big changes afoot in NASA's exploration program, with the announcement of a Moon base and a nuclear-powered rocket to Mars. The shakeups come as the agency is just a week away from launching Artemis II, a circumlunar flight carrying a crew of four around the Moon. The Ars space team will be writing extensively about this mission in the days ahead, and we may skip the Rocket Report next week to focus on our Artemis II coverage.

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

NASA announces nuclear rocket demo. NASA's announcement Tuesday that it will "pause" work on a lunar space station and focus on building a surface base on the Moon was no big surprise to anyone paying attention to the Trump administration’s space policy. But what should NASA do with hardware already built for the Gateway outpost? NASA spent close to $4.5 billion on developing a human-tended complex in orbit around the Moon since the Gateway program’s official start in 2019. There are pieces of the station undergoing construction and testing in factories scattered around the world. The centerpiece of Gateway, called the Power and Propulsion Element, is closest to being ready for launch. NASA’s rejigged exploration roadmap, revealed Tuesday in an all-day event at NASA headquarters in Washington, calls for repurposing the core module for a nuclear-electric propulsion demonstration in deep space, Ars reports.

Elon Musk loses big in court; X boycott perfectly legal

Elon Musk loses big in court; X boycott perfectly legal

fivenewscrypto    mars 28, 2026   

On Thursday, Elon Musk lost his lawsuit alleging that advertisers violated antitrust law by colluding on an ad boycott after he took over Twitter, gutted content moderation teams, and disbanded the Trust and Safety Council.

In her opinion, US District Judge Jane Boyle wrote that the lawsuit was dismissed because Musk failed to state a claim. His arguments that advertisers acted against their own best interests by avoiding advertising on his platform, now called X, did not plead facts showing that consumers were harmed. Without consumer harm, there can be no antitrust violation, the judge wrote, deeming the ad boycott perfectly legal.

"The very nature of the alleged conspiracy does not state an antitrust claim, and the Court therefore has no qualm dismissing with prejudice," Boyle said. At one point, she emphasized, "the question underlying antitrust injury is whether consumers—not competitors—have been harmed."

Spotify seeks $300M from Anna's Archive, which ignores all court proceedings

Spotify seeks $300M from Anna's Archive, which ignores all court proceedings

fivenewscrypto    mars 28, 2026   

Spotify and major record labels are seeking a $322 million default judgment from Anna's Archive, which hasn't responded to court proceedings over its scraping of millions of music files from Spotify's streaming service.

The music companies are also seeking a permanent injunction in an attempt to eject the Anna's Archive website from the Internet by cutting off its access to domain and hosting providers. But the plaintiffs previously obtained a similar injunction that proved to be little more than an inconvenience for the shadow library, which has changed providers and said it's working on bolstering its ability to remain online in the face of court orders.

The music companies sued Anna’s Archive in late December and quickly obtained a court order that shut down the shadow library's .org domain, though Anna's Archive has remained online elsewhere. Anna's Archive has filed no response to the lawsuit in US District Court for the Southern District of New York, and the clerk of court last month certified that the defendant is in default.
