One half of making a laptop is giving it the most powerful portable hardware on the market; the other half is squeezing all of that into an extremely thin shell. Fortunately, HP seems to have hit the balance perfectly, as it has just announced the world's thinnest RTX Spark laptops. These allow people to tap into on-board AI without sacrificing portability. HP reveals the OmniBook Ultra 16 for the working professional It's a strong piece of kit Credit: HP The real star of the show in HP's announcements is the OmniBook Ultra 16. We're looking at a laptop designed for heavy-duty AI programming and creative projects, with 128 GB of memory and 1 petaflop of AI performance. That's not to say it's a slacker when it comes to the visuals. As HP puts it, the laptop comes with an impressive screen: A 16-inch 3K OLED display with VESA DisplayHDR™ True Black 1000 certification is paired with quad speakers powered by smart amplifiers to deliver vibrant visuals, deep contrast and immersive audio experiences for content creation, entertainment, and everyday productivity. This is all packaged within an ultra-thin shell that maximises airflow to keep everything cool. It can also run off battery for up to 17 hours, and can tap into fast charging technology to charge to 50% in 30 minutes. HP also reveals the HP OmniBook X 14 and the OmniDesk For those who don't need the most powerful tech Credit: HP The OmniBook Ultra 16 wasn't the only announcement that HP made. The company also revealed the HP OmniBook X 14, which offers maximum portability without sacrificing AI tools. It features a brilliant OLED display, an advanced rear thermal architecture, up to 15 hours of battery life, and rapid charging via a 140W USB-C adapter. Rounding out the lineup is the HP OmniDesk, a compact desktop built for AI performance. It is designed to keep intelligent agents and long-running AI tasks operating continuously in the background, even when the user steps away. The idea is that you can set your AI agents going, go do something else, then come back to see what they've done in the meantime. Both laptops are slated for release this fall via HP.com and major retailers, with exact pricing details for the entire lineup to follow closer to launch.
