Want to run AI models on your own laptop instead of in the cloud? A head-to-head test between two very different machines produced a surprise: the laptop built for local AI could not load the models, while the cheaper general-purpose laptop could. Here is what happened, and what it means if you are shopping for a local AI machine.
RTX Spark vs Snapdragon X2 (Credits: How-To Geek)
The test pitted a $3,200 HP OmniBook Ultra 16 with a 32GB NVIDIA RTX Spark chip, marketed as the laptop chip for running AI agents locally, against a $2,200 Asus Zenbook A16 with 48GB of memory and a Qualcomm Snapdragon X2 Elite Extreme chip. On paper, the RTX Spark machine should have won easily.
RTX Spark vs Snapdragon X2: which laptop actually runs local AI models?
Using the Hermes app, a primary showcase for the RTX Spark, the tester tried to load several local models on both machines. On the RTX Spark, Hermes reported that every model wanted was too big to load. On the Zenbook, the same app loaded three of them in one click. Performance was slow, but the job actually got done.
The lesson is not that one chip is universally better. It is that memory capacity and software support matter more than branding. The Zenbook’s 48GB of memory gave it headroom the 32GB RTX Spark machine lacked for these particular models, and the app’s support on the Snapdragon platform did the rest.
If you are planning to run models locally, check three things before buying: how much memory the machine actually has, whether your preferred app and models support that chip, and which model sizes you realistically want to run. A purpose-built AI label does not guarantee a model will load, and as this test shows, CUDA acceleration cannot help if the model never loads in the first place.
