Somehow, we've already reached the unofficial start of summer: the Memorial Day 2025 deals are here. Though Memorial Day isn't technically until May 26, plenty of brands kicked off their sales early. Leading the way are mattress deals, followed by home and kitchen deals. Below, we've gathered all the best deals so far ahead of Memorial Day, and will be adding to this list as more deals go live.

The number of qubits that have been entangled in quantum computers has nearly doubled within the past year – the increase is happening so fast, it seems to be following a "quantum Moore's law". First proposed by Gordon Moore at Intel in 1965, Moore's law states that the power we can get out of a single traditional computer chip doubles at regular intervals; every year at first, then every two years as manufacturing encountered…

CPUs and GPUs are old news. These days, the cutting edge is all about NPUs, and hardware manufacturers are talking up NPU performance. The NPU is a computer component designed to accelerate AI tasks in a power-efficient manner, paving the way for new Windows desktop applications with powerful AI features. All PCs will eventually have NPUs, but at the moment only some laptops have them. Here's everything you need to know about NPUs and why they're such a hot topic in the computer industry right now.

Diminished tech privacy appears to be another ripple effect from Trump 2.0. The Information reported on Wednesday that Meta has changed its tune on facial recognition. After considering but ultimately bailing on the technology for the first version of its smart glasses, the company is now actively working on wearables that can identify nearby faces. Remember when being a "Glasshole" was considered a faux pas? According to The Information, Meta has recently discussed adding software to its smart glasses that scans bystanders' faces and identifies people by name.

Intel said Wednesday that the company is adding its XeSS 2 technology to even more games, including top-tier titles like Diablo IV and Assassin's Creed Shadows -- pushing them into the "definitely playable" category by increasing framerates up to a whopping four times higher. As part of the announcement, Intel also revealed that some sort of XeSS support now exists in over 200 PC games. XeSS 2 was added in conjunction with the 250 Intel Arc B580 ("Battlemage") architecture at the end of 2024, a "budget" graphics card that certainly helped alleviate some of the sticker shock that accompanied cards from AMD and especially Nvidia. It combines upscaling, frame generation, and latency in reduction, and doesn't necessarily require an Intel GPU, either. The most important thing about XeSS is that it applies additional frames where it's really needed -- at the low end.

It's been one future that sci-fi has promised since Star Trek. Microsoft now says that that future is arriving, at least within a small corner of Windows 11. Microsoft is promising that you'll be able to use natural language to change aspects of your Windows 11 Settings menu, and Windows will go out and make those changes for you using "agents," or small bits of AI that will work on your behalf -- at least if you own a Copilot PC with an AI-accelerating NPU onboard. Microsoft has begun to use its Surface devices as a showcase for its latest software, and the new 13-inch Surface Laptop and 12-inch Surface Pro are no exception. They'll serve as launch vehicles for Windows Recall, semantic search, and Click-to-Do, but also brand new features like agentic AI and relighting features for Photos, object editing and sticker generation for Paint, and more.

This Mother's Day, gift Mom tech gadgets that simplify life, connect and show love. Tech expert Kurt Knutsson offers some ideas. Stuck on what to get Mom this Mother's Day? Flowers are nice, but if you really want to wow her, how about something that blends thoughtfulness with a little tech? We're not talking about complicated robots; think clever gadgets that make life easier, keep her connected and maybe even add a bit of sparkle to her day. From a cutting-edge smartwatch to a smart mug that keeps her coffee just right – because who has time for lukewarm?

The Switch 2 is nearly here, which means the original Switch is entering its twilight years. It's been eight years since Nintendo released its revolutionary hybrid console, and while many fans have spent the last couple of those itching for the device to be replaced, now seems like an opportune time to look back at what its legacy may wind up being (while acknowledging that it still has some life ahead of it). Instead of bleating on myself, though, I turned to the rest of the Engadget staff to see what comes to mind when they think of the Switch, as just about everyone on the team has played with the console. We've collected our reflections below -- some take a bigger-picture view, some are more personal, some contradict others' experiences entirely. There's plenty more that went unsaid. But I think that's part of the Switch's beauty; it's a device that's resonated with so many, in so many different ways, in its near-decade on the market.

Originally a super-fancy form of upscaling, "DLSS" has become gamer shorthand for a host of allegedly AI-powered graphics tricks exclusive to Nvidia's graphics cards. In the PCWorld lab, Will Smith has been breaking down some of the different ways that upscaling and other AI tricks work in the latest version of Nvidia's drivers and comparing how they perform on different cards. Also, a wild Brad Chacos appears! Will and Brad show that while it's easy to compare some of this tech if you're watching frame-by-frame and zooming in for the finest details--especially on games that have a dedicated benchmark tool--it can be a lot harder to spot in motion in a way that actually affects your gaming experience. Also note that some of the most recent models, like Transformer Upscale, are only available on some games.

Over the last couple of weeks I have been tidying our attic, and while the general aim has been to prevent its contents from collapsing through the ceiling, I have a side-mission. My most valued possession when I was twelve was a Casio GD-8 Car Race watch – a digital timepiece that included a built-in racing game on its tiny monochrome LCD display. Two big buttons on the front let you steer left and right to avoid incoming vehicles and your aim was to stay alive as long as possible. I lost count of the number of times it was confiscated by teachers at my school. I used to lend it to the hardest boys in the year, thereby guaranteeing me protection against bullies.
