Each time I put on the glasses, I tended to put the cable, which comes out the front, around my arm to the left side of the laptop. The founders told me they used Qualcomm because it has some spatial technology that Intel doesn't offer just yet. This SoC originally launched in 2020 and has since been succeeded several times in the mobile space. The SoC powering the Spacetop is a Qualcomm Snapdragon 865 with eight Kryo 585 cores, going up to 3.1 GHz, qwith Adreno 650 graphics. And because of a limited field of view, you will have to turn your head to see parts of your "screen." If you move, you hold shift on both sides of the keyboard to re-center the desktop in front of you. Instead of shuffling between windows, now you have to find the one you want and zoom into it with three fingers on the trackpad to make it legible. But it also means there's new complications. But there sure feels like far more screen real estate than on a laptop. I can't tell you if Sightful hits its 100-inch virtual screen claim. This works, but as a person who meets the mobile, multi-window criteria Sightful is looking for, the lack of apps feels like a dealbreaker it's effectively a fancy AR Chromebook. When I asked about the lack of the Google Play Store (or any other app store), I was told that they see "the web as a first-class citizen." Everything in the start menu, like Discord and Spotify, actually served as bookmarks for websites in the browser. At the moment, the Spacetop is limited to web apps. There's also a very small e-ink display on the unit, though Sightful was only using it to show off its logo. There are two USB Type-C ports on the side of the laptop, which can be used for peripherals or to attach a physical display. But in the demo units I tried, the keyboards felt a bit loose. The keyboard and touchpad feel like they belong to a laptop (they're produced by laptop manufacturer Wistron). Yes, you need to be approved at this point for them to take your money. Once an applicant is approved, they will pay $2,000 for their hardware. People who need more powerful hardware, like gamers, will be asked to wait. The company wants people who they think can use this the way envisioned - using lots of windows, largely web apps - trying the Spacetop first. To start, Sightful founders Tamir Berliner and Tomer Kahan (formerly of Magic Leap) told me that while the Spacetop is ready to start shipping today, you have to apply for early access. Spacetop OS (Android Open Source Project)ġ0.47 x 9.8 x 1.57 inches (266 x 249 x 40 mm) Clock speed and other aspects of the platform will also play a role.Qualcomm Snapdragon 865 - Kryo 585 8-cores, up to 3.1 GHz Meanwhile, it should be noted that IPC alone does not necessarily mean that Loongson's 2nd Generation CPUs that rely on its LoongArch microarchitecture will be as fast as AMD's Ryzen 5000-series or Intel's 11th generation Core processors. Matching IPC performance of AMD's Zen 3 microarchitecture or Intel's Tiger Lake microarchitecture is a big deal for Loongson, whose current CPUs are considerably slower than processors from the leading suppliers. Enablement alone does not necessarily mean that the new chip is about to be taped out, or is progressing rapidly, but at least it means that its designers are confident enough about its success. The CPU will only require software handling in situations like page faults.Īnother feature enabled by another patch for Loongson's 3A6000's processors is moving away from full completion barrier (dbar 0) hint to a set of more fine-tuned hints for different memory barriers, which can improve performance.ĬPU enablement in Linux is an important milestone for any processor development cycle, since it signals that development is proceeding. Now, the company's engineers posted patches enabling the 3A6000's new memory management unit (MMU) or page table walker (PTW) that can handle address translation exceptions (like TLBI, TLBL, TLBS, TLBM) directly in the hardware, boosting performance. Loongson shared details about the progress of its 3A6000-series CPU development last November when it revealed that the design phase of the project had been concluded and that samples of the processors would be available in the first half of 2023. The company expects its upcoming LoongArch-based CPUs AMD's Zen 3 in instruction per clock (IPC), which will enable Loongson to challenge leading processor manufacturers. Loongson has posted the first Linux patches to enable support for its next generation 3A6000-series processors, reports Phoronix.
