Microsoft’s $2,599 Surface Laptop Ultra ties its 120-billion-parameter claim to high-end memory
Pre-orders opened October 7, with availability beginning October 16. The 120-billion-parameter claim depends on high-memory configurations, not every model.
Microsoft opened pre-orders on October 7 for the Surface Laptop Ultra, a $2,599 laptop built around Nvidia’s RTX Spark chip and marketed for running large AI models on the device. The company says some configurations can run models with more than 120 billion parameters locally. Availability begins October 16.
The biggest AI claim depends on the configuration, not just the starting price. Microsoft lists up to 128 GB of unified memory, but memory varies by model. The $2,599 entry model does not automatically include the maximum capacity.
What the price buys
Microsoft lists a US starting price of $2,599, while its website shows the laptop at $2,599.99. Pre-orders are available through Microsoft and select retailers worldwide, the company says.
- Starting price: $2,599, or $2,599.99 on Microsoft’s website
- Top configuration: $5,899, according to Reuters
- Top configuration specs: 20-core processor, 128 GB of memory and one terabyte of storage
The top configuration costs more than twice the starting price. That gap points to different levels of local AI capacity, rather than one uniform experience across the lineup.
The 120-billion-parameter claim has a catch
Microsoft says RTX Spark combines Nvidia’s processor and graphics hardware with shared, or unified, memory. The company claims the maximum configuration can run models with more than 120 billion parameters locally. It also cautions that the graphics processor can use less memory than the system’s total, and that performance depends on configuration and workload.
These are Microsoft’s claims, not independent benchmark results for a finished retail laptop. Model size alone does not show how quickly a model will respond or how well a specific configuration will handle a task.
Windows can split work between the PC and cloud
Microsoft also announced Windows features that can use local models for some tasks and cloud services for others. The company says Copilot will be able to use local context and models with user permission, while routing harder tasks to the cloud. Rollout timing and availability may vary by device, market and platform.
For buyers, the trade-off is clear: the entry price starts at $2,599, but Microsoft’s largest-model claim is tied to the high-memory end of the lineup.
