No more secrets: Nintendo Switch 2 report answers the mystery behind the processor
TL;DR New details have emerged about the Nintendo Switch 2's technical specifications.
These details answer lingering questions about the console's processor.
The system also uses a file decompression engine to make loading games faster and more power-efficient.
The arrival of the Nintendo Switch 2 is almost upon us, with only a few more weeks left to wait. The console maker has already shared a spec sheet, detailing the hardware packed inside. However, Nintendo has been vague about the processor sitting inside the hybrid console, only stating that it's a 'custom processor made by NVIDIA.' A new report has now shed some light on this lingering question.
Richard Leadbetter of Digital Foundry has shared new details about the Switch 2's SoC. This information dives deep into the technical makeup of the processor. In addition to the chip, this report also reveals a few details in other areas that have not previously been mentioned.
Starting with the CPU, Leadbetter writes that it features a ARM Cortex A78C, which runs on an ARMv8 64-bit instruction set. There's also 64K of L1 instruction cache and 64K of L1 data cache. Meanwhile, all eight cores of the L2 have 256K and can share 4MB of L3 cache. Six of the eight cores in the ARM Cortex A78C are available to developers, and the remaining two are reserved for running the OS.
Something peculiar Leadbetter found is that the CPU runs at 1100MHz in handheld mode, while shifting down to 998MHz in its performance mode. It's speculated that memory bandwidth drops in handheld mode may have something to do with why the system's CPU runs faster in that mode. Finally, it's mentioned that the maximum clock speed for the CPU is 1.7GHz.

As for the GPU, Nintendo has switched from the NVIDIA Maxwell architecture used in the GTX 900 series to the Ampere architecture used in the RTX 30 series. This GPU features 1536 CUDA cores with clock speeds of 561MHz (handheld mode) and 1,007MHz (docked). For the maximum clock speed, we're looking at 1.4GHz.
The rest of the report mostly covers details that were already confirmed by the spec sheet Nintendo Japan released last month. However, there are a few details we haven't heard about until now.
One such detail is the inclusion of a file decompression engine (FDE). File loading and decompression can usually be handled by the CPU, but the Switch 2's CPU can hand off that responsibility to the FDE, making load times faster and more power efficient. Another aspect of the Switch 2 that hasn't been talked about is multi-touch. Like the original Switch, the Switch 2 will also feature a 10-point multi-touch capacitive touchscreen.
The Nintendo Switch 2 launches in the US on June 5. It will be available for $450, with the price going up to $500 for the Mario Kart World bundle.

Gearbox's Randy Pitchford celebrates Borderlands 4 going gold by explaining what that means: "The moment we're done is about as monumental as anything we experience in our lives"
When you buy through links on our articles, Future and its syndication partners may earn a commission. Borderlands 4 has officially gone gold, Gearbox has announced, and just in case you don't know exactly what that means, let studio head Randy Pitchford put his reading glasses on, lean back in his creaky wooden rocking chair, and tell you the origin story behind the phrase. Alternatively, if you're short on time, I can just tell you real quick: it means the game's done, theoretically anyway. These days, developers continue working on games up to and through release, fixing bugs and working on future content releases. But, essentially, it means Gearbox has a master copy of the game that's, again theoretically, ready for launch. Back in the days of the disc, though, things were different. "For videogame development, where a lot of emotion and creativity from a group of hardcore devs working together on a team, the moment we're done is about as monumental as anything we experience in our lives," Pitchford said, prefacing a tweet thread with some insights into the process of securing that coveted gold certification clearing the way for launch. "So, when is the exact *moment* that a video game is 'done'?" As Pitchford explained, back when games were still only released on physical discs and sold in stores, but recent enough that information largely traveled via the internet instead of magazines and retail endcaps, devs would send those physical discs often by mail to press, tech companies, and most importantly, first-party hardware companies like PlayStation, Xbox, and Nintendo for certification. "When we were ready, we'd submit a build of the game as a candidate to be the 'final' version," Pitchford said. "The 1st party would receive the game and make master discs that they would run through their tests and, hopefully, approve it for licensing and manufacturing. "When the first parties approved the build, they would create a new master copy of that software to be sent to the physical media manufacturer to be replicated onto the discs that would be packaged and sold to customers," Pitchford said. "Those master discs were literally gold colored." So there you have it. In case you hadn't already heard the origin story a thousand times, the phrase "gone gold" is from back in the day when there were actual gold-colored discs. Thanks, Randy. "Today, the process doesn't involve burning builds onto gold colored discs the way it once did," he added. "But, we still use the term 'gone gold' to describe the *moment* the game is finished. Today 'Gone Gold' means that the video game has been approved for launch on all platforms." Borderlands 4 boss confirms "there will be a download, even for physical copies" on Switch 2, which will "mostly" run at 30 FPS "with some dips"

Nvidia's China Nightmare? H20 Chip Faces Backdoor Allegations in High-Stakes Trade Showdown
China's been turning up the heat on Nvidia (NASDAQ:NVDA), and not in a good way. This week, the country's top internet watchdog summoned Nvidia reps over what it calls serious security risks tied to the H20 chipa product Nvidia designed specifically to meet U.S. export rules. State media pulled no punches either. In a commentary published Friday, the People's Daily warned of potential chip backdoors triggering a nightmare, saying it couldn't allow infected semiconductors into its digital infrastructure. Nvidia responded firmly: Cybersecurity is critically important to us, adding that its chips don't contain any remote access pathways. Still, in today's geopolitical climate, that reassurance may not be enough. Warning! GuruFocus has detected 5 Warning Signs with NVDA. Here's where things get messier. Just a few weeks ago, the U.S. agreed to lift restrictions on H20 sales to China as part of a broader deal involving rare-earth magnetsmaterials critical for everything from smartphones to fighter jets. Commerce Secretary Howard Lutnick had framed the H20 resumption as a meaningful breakthrough after bilateral talks in London, and Treasury Secretary Scott Bessent said the magnet issue was solved. But with Beijing now putting the H20 back under the microscope, it's unclear whether Nvidia has actually received the licenses it needs to ship the chips. And if China decides the H20 isn't up to pareither technically or politicallythose sales may stall before they even start. Meanwhile, CEO Jensen Huang has been walking a tightrope. Fresh off a high-profile visit to Beijing, Huang praised China's AI momentum and national champions like DeepSeek, all while pushing back on the idea that Nvidia would ever install surveillance backdoors into its products. He called the suggestion not only false, but bad business. Still, the reality is this: Nvidia's H20, already weaker than its flagship GPUs, now faces a political test that could matter more than its specs. Investors watching the tech standoff might want to pay close attention to what happens nextbecause this chip is turning into a geopolitical bargaining chip. This article first appeared on GuruFocus.
