The vendor's number on the VideoCardz page is $2,599. Microsoft says the Surface Laptop Ultra ships on October 16, with preorders open and a 15-inch mini-LED display, haptic trackpad, and three USB-C ports. The base machine uses the 18-core RTX Spark, a 5,120-core Blackwell GPU, and 24GB of unified memory.

The HP filing added a $2,999 entry and a $4,999 top for the OmniBook X 14 and OmniBook Ultra 16, but it left the Surface base configuration unpriced. That omission matters because the Surface entry uses the reduced 18-core and 5,120-core version, while full N1X configurations can reach a 20-core Grace CPU, a 6,144-core Blackwell GPU, and 128GB of unified memory.

The judgment is that Microsoft is anchoring the RTX Spark laptop market at a price that buys a cut-down chip, not the full N1X ceiling. The document does not prove that 24GB of unified memory is enough for the 5,120-core GPU under sustained load, and it does not show whether the 18-core path is the practical ceiling for most buyers. For the buyer, the constraint is not the launch date but the missing power, thermal, and battery data.

The buyer's useful comparison is not against a desktop RTX card but against the HP entry price and the missing top-tier price. The $2,599 Surface base is cheaper than the HP $2,999 entry, but the document does not say whether the HP machines use the same 18-core path or the full N1X. That gap keeps the value question open.

The page leaves battery life, weight, power draw, regional availability, exact HP configurations, and specific SKUs unmeasured. It is not a performance claim. The review embargo lifting on ship day also means the market will learn the real constraints after the first units are already in hand.

The $2,599 entry fixes a reduced 18-core/5,120-core/24GB configuration, while the 20-core/6,144-core/128GB N1X remains unpriced. Without power, thermal, and battery data, the buyer cannot infer sustained performance or the fab's thermal budget.
