On launch morning, NVIDIA's Japanese account announced that RTX Spark was on sale from that day (in Japanese) 1.

A few hours earlier, the benchmark lab Artificial Analysis had posted its first results for an RTX Spark laptop on X. On Qwen3.8 27B, it says, the laptop finished a recorded local agent workload in 18.7 minutes 2.
What was measured
The test is the lab's AA-AgentPerf-Local. It is an open-source tool for measuring how fast a laptop or workstation serves an AI agent, and it replays recorded agent sessions against a model server running on the machine 3.
NVIDIA's RTX Spark N1X puts up to 128 GB of unified memory and a Blackwell GPU in a Windows laptop. In our first AA-AgentPerf-Local results, an RTX Spark laptop completes our local agent workload on Qwen3.8 27B in 18.7 minutes

The test machine was a prototype 15-inch Surface Laptop Ultra 4. According to Artificial Analysis, it was plugged in, with Windows set to high-performance mode, using NVIDIA's published llama.cpp recipes where available 4. So this is a conditional measurement on a prototype. It does not mean every shipping unit will land on the same result.

Reading the results
The default workload on Qwen3.8 27B is 8 recorded agent tasks and 168 model turns 2. Artificial Analysis says the RTX Spark laptop finished in 18.7 minutes, close to DGX Spark at 17.3 minutes 2. Its comparison: 2.0x faster than the MacBook Pro (M5 Pro, 64 GB, 37.6 minutes) and 1.8x faster than the AMD Ryzen AI Halo (34.5 minutes) 2.
The fastest machine was the GeForce RTX 5090 desktop, at 4.9 minutes 5.
A second model: on Qwen3.6 35B A3B, the lab says the laptop takes 7.6 minutes, close to DGX Spark at 7.3 minutes and 1.6x faster than the MacBook Pro at 11.9 minutes 6.
The last one is Ling 3.0 Flash, which the lab calls the largest current model it tests 7. The laptop takes 15.3 minutes there, close to DGX Spark at 14.9 minutes and 1.6x faster than the Ryzen AI Halo at 25.1 minutes 7. And the lab writes that the model's 77 GB of weights do not fit on the MacBook Pro or on the RTX 5090 7.
That is the reading that matters. On Qwen3.8 27B, the RTX 5090 desktop was quickest 2 5. On Ling 3.0 Flash, its 77 GB of weights do not fit on the RTX 5090, while the RTX Spark laptop, DGX Spark and the Ryzen AI Halo, with their large memory pools, finish the run 7. The dividing line is not only speed but whether the model fits. RTX 5090 was not slow.
Memory and power: NVIDIA's documents
On the memory side, NVIDIA's documentation gives the details. According to NVIDIA, the memory is shared by the CPU and the GPU, on a 256-bit interface with 300 GB/s of bandwidth 8. Its product page lists laptop power (TDP) at 45 to 80 W 9.
Artificial Analysis sees RTX Spark's N1X as essentially the GB10 from DGX Spark (20-core Arm CPU, 6,144-core Blackwell GPU), with up to 128 GB of memory at 300 GB/s 10. That is the lab's reading of the chip, not a claim that the chips perform identically.
Big model weights also need somewhere to live on disk.
If you want to start at your own desk
To try something small at home, one way in is Llama Windows from Hugging Face, a free and open-source app that puts llama.cpp in your Windows 11 tray 11.
According to Hugging Face, it has native support for Windows on Arm 12 and for RTX Spark 13. They say they worked with NVIDIA to have it ready on RTX Spark's first day 14. It also includes a local server with an OpenAI-compatible API, so your own apps and agents can call the same models 15.

PC Watch also ran a headline (in Japanese) saying a llama.cpp Windows app has appeared with day-one support for RTX Spark 16.

Benchmark software is moving too. A 4Gamer headline (in Japanese) reports 3DMark 2.32.8919, released with stronger Windows on Arm support in light of RTX Spark's arrival 19.
Here are some machines. The first card shares a product name with the machine Artificial Analysis tested, but the tested unit was a prototype. Check that the software you want to run supports the machine before you choose.
For comparison, here is DGX Spark.
