Lenovo's Yoga Pro 9n Stuffs 128GB of Unified Memory Into a 3.6-Pound Creator Laptop

Lenovo just dropped a laptop that breaks one of the oldest rules in PC design: pick your poison — a big memory pool or a thin, light machine. The new Yoga Pro 9n (15", Gen 11) stuffs up to 128GB of unified memory into a 3.64-pound chassis, runs on NVIDIA's brand-new RTX Spark platform, and ships with a 15.3-inch OLED that'll make editors drool. Here's the thing, though — this isn't just another spec-bump Yoga. Let's break it down.

What Even Is RTX Spark?

Quick primer before we go further. RTX Spark is NVIDIA's new Windows-on-Arm platform — think of it like Apple's M-series approach, but for Windows. The CPU, the GPU, and the memory all live on one package and share one big pool of RAM. In this machine, that's an NVIDIA Grace-class Arm CPU paired with a Blackwell RTX GPU, and the whole thing is called the RTX Spark N1X.

You get two flavors: an 18-core CPU with a 5,120-core GPU, or a 20-core CPU with a full 6,144-core GPU. There's an NVIDIA NPU on board for AI chores, and Lenovo markets this as a Copilot+ PC running Windows 11 Home or Pro. The headline benefit of that shared memory pool? Local AI models — the kind that used to need a desktop with a fat graphics card — can actually fit in RAM. The config goes all the way up to 128GB of 256-bit LPDDR5x unified memory running at 9,400MT/s across 16 channels. That's double the ceiling of Lenovo's own Yoga 9n 2-in-1.

The Screen and the "Wait, the Trackpad Draws?" Feature

The display is a 15.3-inch PureSight Pro OLED — "PureSight Pro" being Lenovo's name for its color-accurate creator panels. You're looking at 2560 × 1600 resolution (2.5K) in a 16:10 aspect ratio, a 48–165Hz variable refresh rate, and up to 1,100 nits of peak HDR brightness. It covers 100% sRGB and 100% P3 color with Delta E < 0.5 accuracy (that's color-error measurement — under 0.5 means the human eye basically can't tell the difference), plus Dolby Vision and VESA DisplayHDR True Black 1000 certification. Touch is optional.

Here's the fun part: the Force Pad. It's a haptic touchpad with a smart sensor that turns it into a pen-enabled drawing surface, so you can sketch on the pad below the keyboard while looking at the screen — no extra gear. Pair it with the optional Yoga Pen Gen 2 (AES 3.0 tech, meaning serious tilt and pressure precision) and you've got a pocketable Wacom-style setup baked right into the laptop.

Specs That Matter for Real Work

Let's run through the stuff you actually care about:

• Storage: two M.2 2242 SSD slots — up to 1TB in the PCIe Gen 4 slot plus up to 4TB in the PCIe Gen 5 slot. Yeah, two slots in a 0.66-inch machine.
• Ports, zero dongles: two USB4 Type-C (40Gbps, with Power Delivery 3.0 and DisplayPort 2.1), two USB-A (10Gbps, one always-on), HDMI 2.1 good for 8K at 60Hz, a UHS-II SD card reader (the fast standard camera folks need), and a headphone/mic jack. Wi-Fi 7 and Bluetooth 5.4 handle the wireless stuff.
• Battery: 92.5Whr with Rapid Charge Express — 15 minutes plugged in buys you about 3 hours. A 140W USB-C charger is in the box.
• Thermals: Lenovo X Power cooling with dual fans, four heat pipes, and an 80W TDP (that's how much heat the cooling system is designed to dump). Lenovo claims noise as low as 22 dB — library-quiet.
• Extras: a 9.2MP IR camera for Windows Hello face login, four speakers (two tweeters, two woofers) with Dolby Atmos, a backlit keyboard with a Copilot key and 1.5mm travel, and a 175° hinge you can open with one finger.
• Body: 16.7mm × 347mm × 242mm, starting at 1.65kg (3.64lbs) in Thunder Grey aluminum.

It's also got the boring-but-important stuff covered: Secured-core PC with the Microsoft Pluton security processor, MIL-STD-810H durability testing, carbon-neutral certification, and ENERGY STAR 9.0.

What'll It Cost You?

US preorders open at $2,999.99, and the release date is listed as October 16, 2026. That entry build gets you the 18-core N1X, 32GB of unified memory, and a 512GB SSD. Lenovo's US page is the configure-to-order model, so you can climb from there all the way to the 20-core chip, 128GB of memory, and multiple terabytes of storage. For context, Microsoft's Surface Laptop Ultra and ASUS's ProArt P14 both start at $2,599.99 with 24GB of memory — so Lenovo is charging a premium, but also giving you a much bigger memory ceiling and that OLED panel.

The Bottom Line

The Yoga Pro 9n is one of the first laptops that can run genuinely large AI models locally without turning into a desktop replacement. If you edit video, train or run AI tools, or just want 128GB of RAM in a bag-friendly 15-inch machine, this is a genuinely new category of computer — and the OLED, the port selection, and the drawing touchpad are the cherry on top. Just know you're paying early-adopter prices for the privilege.
