Earlier this month, Microsoft announced its answer to Apple’s MacBook, a luxury laptop that’s being called the Surface Book. The company billed the device as being twice as powerful as the MacBook Pro, and now some users are attempting to verify that claim.

While Microsoft was keen to detail certain selling points of the computer — we heard plenty about its 3,000 x 2,000 PixelSense display and the various advantages that its clamshell 2-in-1 design offers up. However, we didn’t hear specifics as to just what users could expect to find under the hood.

Thankfully, the Surface aficionados of the device’s dedicated subreddit have been working hard to find those answers. They’ve been heading out to test the Surface Book at Microsoft’s retail locations around the country, and they’ve been able to uncover some new information about the Nvidia GPU that’s being used.

These users found that the Surface Book uses a custom GPU, which is referred to as both 1347 and 134B. Based on its specs, it seems roughly equivalent to Nvidia’s GeForce 940M, according to a report from Hexus based on the findings shared via reddit. The GPU has 384 CUDA cores, a clock speed of 954MHz, and one gigabyte of GDDR5 memory.

Being that their research is being carried out on store display models, the Reddit users in question weren’t able to tear the machine to pieces to find out exactly what components are inside. Instead, they used system tools like GPUz and the Nvidia control panel.

The Surface Book is Microsoft’s first foray into building laptops, and early impressions seem positive. However, the fact that the company is keeping quiet about what’s inside the device might draw some criticism from the Windows faithful, given that PCs are known to foster modifications rather than lock users out of a system’s internal components.

The Surface Book will retail for $1,499, with preorders shipping on Oct. 27.

This new GPU feature is ‘a whole new paradigm’ for PC gaming
RX 7900 XTX slotted into a test bench.

Microsoft has released its Agility SDK 1.613.0, which features some critical components that will be shown to developers at the Game Developers Conference (GDC) in San Francisco next week. The most interesting component is Work Graphs, which Microsoft describes as "a whole new paradigm" for graphics cards.

Work Graphs enable GPU-driven work. Normally when you're playing a PC game, there's a relationship between your GPU and CPU. Your CPU gets work ready and sends it to your GPU, and then your GPU executes that work. Work Graphs is an approach that allows your GPU to schedule and execute its own tasks, which has some massive implications for performance.

Microsoft’s next event could reveal the Surface Pro we’ve been waiting for

Microsoft has just confirmed that it will hold a Surface and Windows event on March 21, as previously rumored. The company went live with a placeholder webpage for a digital event titled "New Era of Work," teasing some new announcements and how it will " advance the new era of work with Copilot."

Set to kick off at 9 a.m. PT on March 21 , it's looking as though this event might be a little bit more focused on the business side of things, rather than consumer offerings. Microsoft doesn't get into many details, but mentioned how the event will be focused on "the latest in scaling AI in your environment with Copilot, Windows, and Surface."

The Surface Pro 10 sounds amazing, and it may be coming soon

Microsoft could be getting ready to reveal the Surface Pro 10 and Surface Laptop 6 sooner than expected. Reporting from Windows Central's Zac Bowden indicates the devices might be announced on March 21, and could feature both Intel Core Ultra and Snapdragon X Elite chips under the hood, along with some design tweaks.

These new Surface devices are expected to go all-in on AI features in Windows 11. More important is that we could see the next Surface Laptop in a new ARM-based variant in addition to one with a traditional Intel Core Ultra CPU. This change in chips should not only bring more choice like the Surface Pro 9 did, but also performance gains that can help the devices rival what Apple has accomplished with the iPad Pro, as well as the new MacBook Pro with the M3 chip.
