NVIDIA has officially pulled the wraps off RTX Spark, a new Arm-based PC platform that could end up being one of the more interesting Windows launches of the year.
Announced by Jensen Huang during his Computex 2026 keynote, RTX Spark combines an NVIDIA Grace CPU, a Blackwell-based RTX GPU, and a large pool of unified memory into a single platform aimed at laptops and compact desktops.
The hardware itself is what makes the announcement stand out.
The CPU uses a 20-core Arm design developed in collaboration with MediaTek. According to NVIDIA, it combines ten Cortex-X925 performance cores with ten Cortex-A725 efficiency cores, a configuration that should look familiar to anyone following the smartphone chipset market. In a way, RTX Spark feels like NVIDIA taking ideas that worked well in flagship phones and scaling them up for PCs.
Then there is the GPU.
RTX Spark integrates a Blackwell graphics processor with 6,144 CUDA cores and fifth-generation Tensor Cores. NVIDIA claims up to 1 PFLOP of AI performance, which is the sort of figure that would have sounded absurd for a thin laptop not all that long ago.
Perhaps the most interesting part is the memory architecture. Instead of treating system memory and graphics memory as separate pools, RTX Spark uses up to 128GB of unified LPDDR5X memory shared across the entire system. For AI workloads especially, that could end up being just as important as the raw processing power.
NVIDIA is also leaning heavily on its existing software ecosystem. CUDA, TensorRT, DLSS, Reflex, ray tracing, and the rest of the RTX stack are all part of the package. That gives the platform an advantage that many Windows-on-Arm efforts have struggled with in the past: software support.
The company showed plenty of AI-focused demos during the keynote, but realistically, many buyers will probably care just as much about battery life and gaming performance. NVIDIA says RTX Spark devices can be as thin as 14mm while still delivering high-end graphics capabilities, although we’ll have to wait for independent testing to see how those claims hold up.
The first systems are expected from ASUS, Dell, HP, Lenovo, MSI, and Microsoft’s Surface division later this year.
There is still a lot we don’t know, including pricing and real-world battery life. But one thing is fairly clear already: NVIDIA is no longer content with supplying GPUs for PCs.
