Nvidia RTX Spark Tested: What Nvidia's First PC CPU Really Can Do

TVS News AI, editorially supervised, presents Nvidia RTX Spark Tested: What Nvidia's First PC CPU Really Can Do.

Nvidia has unveiled its first complete PC platform for Windows laptops: the RTX Spark. It combines a Blackwell GPU, an Arm processor, and up to 128 GB of unified memory in a single chassis. Frandroid tested it in the Asus ProArt P16 — against a gaming laptop with an RTX 5070, a Mac with Apple Silicon, and a Windows PC with AMD's Ryzen AI Max+ 395.

For you, this is especially interesting if you work with local AI models on your notebook. Shared memory for GPU and CPU was previously known mainly from the Apple Silicon world — the RTX Spark now brings that concept to a Windows notebook. Up to 128 GB of total capacity exceeds what classic gaming laptops typically deliver in two RAM modules.

What this really delivers in games, daily AI use, and on battery is what Frandroid tested in three disciplines. The full review provides the benchmark numbers, temperatures, and runtimes — here are the core facts about the platform itself.

What's inside the RTX Spark

Frandroid describes the RTX Spark as Nvidia's first complete chip for Windows notebooks. On a single package sit a Blackwell GPU, an Arm processor, and up to 128 GB of unified memory. With this architecture, Nvidia follows the concept Apple established with its M-series: GPU and CPU access a shared memory pool — instead of splitting two separate RAM modules, data for graphics and processor sit in a common pool.

Four devices, three disciplines — the test setup

The test in the Asus ProArt P16 ran in three scenarios: gaming, local AI, and battery life. The comparison devices represent the current laptop spectrum:

• Gaming laptop with RTX 5070 — dedicated GPU reference, the benchmark for Windows gamers.
• Mac with Apple Silicon — the current standard for efficiency and AI on the notebook.
• Windows PC with AMD's Ryzen AI Max+ 395 — direct competitor in the new Windows SoC segment.

What this means for you

With the RTX Spark, an Nvidia SoC with a large unified memory architecture is coming to Windows laptops for the first time. If you work with local LLMs, Stable Diffusion, or other AI workloads, this could solve the typical RAM bottleneck — the concrete numbers from the Frandroid test are in the linked article.

5 points that are already clear

First complete Nvidia SoC for Windows. The RTX Spark is, according to Frandroid, Nvidia's first complete chip for Windows notebooks.

Three cores in one chassis. Blackwell GPU, Arm CPU, and up to 128 GB of unified memory share a single package.

First test device. Asus uses the platform in the ProArt P16 — a creator laptop, not primarily a gaming device.

Comparison against the key competitors. RTX 5070 gaming laptop, Apple Silicon Mac, Ryzen AI Max+ PC.

Three test disciplines. Gaming, local AI, battery life.

Conclusion

The RTX Spark is Nvidia's conceptual stroke: for the first time, the manufacturer delivers a complete SoC for Windows laptops from its own hand, with Blackwell GPU, Arm CPU, and up to 128 GB of unified memory. The fact that Frandroid pits the platform in the Asus ProArt P16 directly against the RTX 5070, Apple Silicon, and Ryzen AI Max+ 395 shows that Nvidia is not shying away from the comparison. The final answer on performance, efficiency, and price is delivered by the detailed review at Frandroid.
