Nvidia RTX Spark Combines 20-Core Grace CPU With 5070-Like Blackwell GPU
Credit: Nvidia
Nvidia announced its new RTX Spark platform at Computex 2026, targeting the desktop and mobile CPU market in a big way. Set to compete directly with Intel and AMD in a similar manner to Qualcomm's X range of SoCs, the new chip combines 20 ARM CPU cores with 6,144 Blackwell CUDA cores for what could be a potent combination—though questions remain about compatibility and emulation.
Nvidia says this chip is designed to handle varied workloads, including AI development, content creation, and gaming. The top configuration will support up to 128GB of LPDDR5X unified memory, which Nvidia says will be linked to the CPU and GPU via its NVLink-C2C technology, delivering bandwidth comparable to PCIe 5 x5. As Videocardz highlights, this all but confirms this is a platform based on Nvidia's previous AI-dev-first system, the GB10 in the DGX Spark.
The RTX Spark, however, is much more intriguing...
