Intel Core Ultra 9 285HX — Processor model
The same graphics card runs with different power limits in different laptops; the real difference is here.
NVIDIA GeForce RTX 5090 Laptop GPU — Graphics card model · 175 W — GPU power limit (TGP) · Yes — MUX switch
Panel type, resolution, and refresh rate — these determine every hour you spend looking at the screen.
18 inch — Screen size · 3840x2400 — Resolution · 120 Hz — Refresh rate · Mini-LED — Panel type · 1000 nit (HDR) — Brightness
Battery capacity and charging power; actual battery life comes from owner reports.
99.9 Wh — Battery capacity · Yes (140W) — USB-C charging
Is RAM soldered, how many M.2 slots are free — the info that determines how many years your laptop will last.
Yes (2 SO-DIMM, up to 96 GB) — RAM upgradable · 96 GB — Maximum supported RAM · 2 — Number of M.2 slots
A usage guide built from the specs and the editors' tags; not a test result.
For gaming; tagged from the display's refresh rate and the chip's class. We have not measured frame rates or heat ourselves.
Good fitFor heavy work use; tagged from the battery and display specs. We have not timed the battery ourselves.
Good fitThe Kacbu editors' assessment of the specifications the maker publishes. We do not test devices ourselves, so nothing here is a measured result. Anything taken from an independent review is shown with its publication and date in the Press section.
Instead of tracking today's retail price, Kacbu keeps the product's official launch information as a reference.
The manufacturer's official announcement date.

Each answer is computed from spec data and editor tags; where there is no data, there is no page.
Whether a model runs on your machine is decided first by the graphics card's memory: the model file has to fit in VRAM with room left for the context window and the runtime. The states below are computed from memory alone; software support (CUDA, ROCm, Vulkan) is a separate matter.
Largest model that runs comfortably: gpt-oss-20b
Rule: 1.5× the requirement in memory is Comfortable, 1.15× Runs, 0.6× Limited; the requirement is the default package size, or the maker's stated minimum where there is one (a stated minimum counts as fitting at exactly that figure). Package sizes are the Ollama library's, minimums the maker's own statement; read on 2026-09-11. Sources: ollama.com/library/qwen3.5, ollama.com/library/gpt-oss, openai.com/index/introducing-gpt-oss
