NVIDIA’s RTX Spark laptops have reached stores, with models from several manufacturers starting at $2,599, according to Techeblog. Their most notable feature for AI users is up to 128GB of shared memory, giving the CPU and GPU one pool to draw on for local workloads.
NVIDIA Watch analysis
What happened
The laptops pair a Grace CPU, designed with MediaTek, and a Blackwell RTX GPU in one superchip. Techeblog says top-tier versions combine 20 CPU cores with 6,144 CUDA cores; lower-end configurations have 18 CPU cores and 5,120 GPU shaders. Available models range from 14 to 16 inches, with some offering OLED or mini-LED screens.
The shared memory is the key distinction from a conventional laptop with separate system RAM and graphics memory. Techeblog says 64GB or 128GB configurations can run larger language models locally, potentially reducing the need to manage memory carefully or send work to the cloud. It also reports NVIDIA’s claim of up to one petaflop of FP4 AI performance at 45 to 80 watts. That is a company performance claim, not a like-for-like independent test.
Why it matters
Local AI is often constrained by memory as much as raw processing power. A laptop that can offer a large shared pool could make running bigger models practical without a workstation or cloud account. The catch is the price: the reported starting point is $2,599, and demanding AI sessions are likely to test battery life.
Our read
This is a real attempt to put serious local AI capacity in a laptop, not just another machine with an AI badge and a cheerful sticker. The memory design is the important part; the useful question is how well real models run, and for how long, once the laptop is unplugged. Techeblog also reports Windows-on-Arm compatibility limits for some older software, so check your workload before treating the spec sheet as a shopping list.
What to watch
- Independent tests of model size, inference speed and power use on the shipping laptops.
- How performance and battery life change during sustained local AI workloads.
- Which 64GB and 128GB configurations are actually available, and at what prices.
Discussion spark: Would you pay a laptop premium for the ability to run larger AI models locally, or are cloud access and battery life more important?
