Nintendo Switch 2 promises to be this year's big (well small) gaming platform launch. It goes up against a growing ecosystem of handhelds based on x86-64 mobile processors running Windows, its main play would have to be offering a similar or better gameplay experience, but with better battery life, given that all of its hardware is purpose-built for a handheld console, and runs a highly optimized software stack; and the SoC forms a big part of this. Nintendo turned to NVIDIA for the job, given its graphics IP leadership, and its ability to integrate it with Arm CPU IP in a semi-custom chip. Someone with access to a Switch 2 prototype, likely an ISV, took the device apart, revealing the chip, a die-shrunk version of the Tegra T239 from 2023.

It's important to note that prototype consoles physically appear nothing like the final product, they're just designed so ISVs and game developers can validate them, and together with PC-based "official" emulation, set up the ability to develop or port games to the new platform. The Switch 2 looks very similar to the original Switch, it is a large tablet-like device, with detachable controllers. The largest chip on the mainboard is the NVIDIA Tegra T239. Nintendo Prime shared more details about the chip.

Arm has announced a pair of new Armv9 CPU cores today, alongside a refresh of a third. The new additions are the Cortex-X925—which is a huge model number jump from the previous Cortex-X4—and the Cortex-A725 which should be an upgraded Cortex-A720. Finally the Cortex-A520 has been refreshed to bring a 15 percent power efficiency improvement as well as support for 3 nm production nodes. Arm claims that the Cortex-A925 delivers its highest performance improvement ever over a previous generation with a single core uplift of up to 36 percent and an AI performance improvement of up to 46 percent compared to the Cortex-X4. The Cortex-X925 will support up to 3 MB private L2 cache and is tape-out ready for 3 nm production nodes.

The Cortex-A725 is said to offer a 35 percent performance efficiency improvement over the Cortex-A720 and it's been given performance boosts both when it comes to AI and gaming workloads. It's said to be up to 25 percent more power efficient than the Cortex-A720 and L3 cache traffic has been improved by up to 20 percent. Again, the Cortex-A720 is ready for production on a 3 nm node. Finally, Arm has also updated its DynamIQ Shared Unit to the DS-120 and here Arm has managed to reduce the typical workload power by up to 50 percent and the cache miss power by up to 60 percent. The DSU-120 scales to up to 14 Arm cores, suggesting that we might get to see some interesting new SoC implementations in the coming years from Arm's partners, although Arm's reference platform is a 2-4-2 configuration of the new cores.

Mobile devices touch every aspect of our digital lives. In the palm of your hand is the ability to both create and consume increasingly immersive, AI-accelerated experiences that continue to drive the need for more compute. Arm is at the heart of many of these, bringing unlimited delight, productivity and success to more people than ever. Every year we build foundational platforms designed to meet these increasing compute demands, with a relentless focus on high performance and efficiency. Working closely with our broader ecosystem, we're delivering the performance, efficiency and intelligence needed on every generation of consumer device to expand our digital lifestyles.

Today we are announcing Arm Total Compute Solutions 2023 (TCS23), which will be the platform for mobile computing, offering our best ever premium solution for smartphones. TCS23 delivers a complete package of the latest IP designed and optimized for specific workloads to work seamlessly together as a complete system. This includes a new world-class Arm Immortalis GPU based on our brand-new 5th Generation GPU architecture for ultimate visual experiences, a new cluster of Armv9 CPUs that continue our performance leadership for next-gen artificial intelligence (AI), and new enhancements to deliver more accessible software for the millions of Arm developers.

ARM processors have been making forays into hitherto shallow markets, with it's technology and processor architectures winning an ever increasing amount of design wins. Most recently, Microsoft itself announced a platform meant to use ARM processors in a server environment. Now, ARM has put forward its plans towards achieving a grand total of 100 billion chips shipped in the 2017-2021 time frame.

To put that goal in perspective, ARM is looking to ship as many ARM-powered processors in this 2017-2021 time frame as it did between 1991 and 2017. This is no easy task - at least if ARM were to stay in its known markets, where it has already achieved almost total saturation. The plan: to widen the appeal of its processor design, with big bets in the AI, Automotive, XR (which encompasses the Virtual Reality, Augmented Reality, and Mixed Reality markets), leveraged by what ARM does best: hyper-efficient processors.
