Surface Laptop Ultra leak frames RTX Spark memory step
A 24 GB unified-memory floor is the clearest signal in the Surface Laptop Ultra leak, with a 32 GB step attached to a 24-core tier.

A prototype Surface Laptop Ultra found near Microsoft's Redmond campus points to the RTX Spark tier that Microsoft may sell as a 24 GB entry model.
The draft's 18-core tier is not shown as final, priced, or able to match the 24-core SKU in sustained load. Clocks, memory bandwidth, TDP, and the exact Surface model name are absent.
The source adds that the prototype carried an entry-level 24 GB unified RAM configuration and a 512 GB SSD, and that screen behavior, driver changes, and benchmark results suggest the unit is not final.
Across Phoronix Test Suite, Blender, and Cinebench, the source's benchmark reports place RTX Spark behind Apple's M5 Pro, and idle power draw increased after the developer preview drivers.
The source also notes that plugged-in and battery operation produced the same performance, and that build quality includes a milled aluminum chassis, a MacBook-like touchpad, and a keyboard praised for punchy key travel.
The source's price estimate sets the floor at $2,800 and the ceiling near $4,500, while the draft leaves the 18-core tier without measured power draw, driver result, or battery number.
The useful fact is the memory step, not the benchmark result. The 24 GB floor frames the entry SKU, but the 18-core tier still lacks clocks, bandwidth, thermal envelope, and sustained workload proof.
18-core RTX Spark · 24 GB of unified memory · 24-core version will start with 32 GB of memory · 15-inch laptops · PixelSense Ultra touchscreen with 2,000 nits of peak HDR brightness · three USB Type-C ports
