Microsoft and Qualcomm are both making a concerted effort to make Windows-on-Arm happen after years of slow progress and false starts. One thing the companies have done to get software developers on board is to offer mini PC developer kits, which can be connected to a software developer's normal multi-monitor setup and doesn't require the same cash outlay as an equivalently specced Surface tablet or laptop.

Qualcomm has announced the Snapdragon Dev Kit for Windows, a small black plastic mini PC with the same internal hardware as the new wave of Copilot+ PCs with Snapdragon X Plus and Snapdragon X Elite processors in them. The box is fairly generously specced, with a slightly faster-than-normal version of the Snapdragon X Elite that can boost up to 4.3 GHz, 32GB of RAM, and a 512GB NVMe SSD.

Unlike the Windows Dev Kit 2023, which appeared to be a repurposed Surface Pro 9 motherboard thrown into a black plastic box, the Snapdragon Dev Kit appears to be purpose-built. It has a single USB-C port on the front and two USB-C ports, an HDMI port, two USB-A ports, a headphone/speaker jack, and an Ethernet port in the back. This isn't an overwhelming complement of ports, but it's in line with what Apple offers in the Mac mini.

If at first you don't succeed, try, try again.

Microsoft has announced a pair of new devices powered by Qualcomm's Snapdragon X Plus and X Elite processors. They're far from Microsoft's first PCs with Arm processors in them—2012's original Surface, the Surface Pro X, and the Surface Pro 9 with 5G have all shipped with Arm's chips instead of Intel's or AMD's. But today's new Surface Pro and Surface Laptop are the first Arm devices to be the primary Surface offerings rather than a side offering, and they're the first to credibly claim that they can both outperform comparable Intel- and AMD-designed chips while offering better battery life, a la Apple's M1 chip in 2020.

One caveat that I hadn't seen mentioned in Microsoft's presentation or in other coverage of the announcement, though: Microsoft says that both of these devices have fans. Apple still uses fans for the MacBook Pro lineup, but the MacBook Air is totally fanless. Bear that in mind when reading Microsoft's claims about performance.

Microsoft is using its new Surface launch and this week’s Build developer conference as a platform to launch its new “Copilot+" PC initiative, which comes with specific hardware requirements that systems will need to meet to be eligible. Copilot+ PCs will be able to handle some AI-accelerated workloads like chatbots and image generation locally instead of relying on the cloud, but new hardware will generally be required to run these workloads quickly and power efficiently.

At a minimum, systems will need 16GB of RAM and 256GB of storage, to accommodate both the memory requirements and the on-disk storage requirements needed for things like large language models (LLMs; even so-called “small language models” like Microsoft’s Phi-3, still use several billion parameters). Microsoft says that all of the Snapdragon X Plus and Elite-powered PCs being announced today will come with the Copilot+ features pre-installed, and that they'll begin shipping on June 18th.

But the biggest new requirement, and the blocker for virtually every Windows PC in use today, will be for an integrated neural processing unit, or NPU. Microsoft requires an NPU with performance rated at 40 trillion operations per second (TOPS), a high-level performance figure that Microsoft, Qualcomm, Apple, and others use for NPU performance comparisons. Right now, that requirement can only be met by a single chip in the Windows PC ecosystem, one that isn't even quite available yet: Qualcomm's Snapdragon X Elite and X Plus, launching in the new Surface and a number of PCs from the likes of Dell, Lenovo, HP, Asus, Acer, and other major PC OEMs in the next couple of months. All of those chips have NPUs capable of 45 TOPS, just a shade more than Microsoft's minimum requirement.
