NVIDIA announces RTX Spark platform for local AI development on single PCs
NVIDIA unveiled RTX Spark, a GB10-based laptop/compact-desktop platform with up to 128GB unified memory and 1 PFLOP FP4 compute aimed at letting developers run coding agents, fine-tune models, and deploy locally. The announcement highlights performance comparisons versus Intel Panther Lake, a Microsoft partnership delivering a PyTorch-CUDA build and Arm-native Python 3.15, and a purpose-built Nemotron 3.5 Bolt 74B-A9B 2-bit model optimized for local agents on RTX Spark.
