## Summary

The update brings general availability support for NVIDIA Vera Rubin architecture, moving beyond early developer access. It also expands Windows on Arm support to DGX Station for Windows and introduces new driver modes for Rubin GPUs, replacing the older TCC mode.

Key improvements include updates to Multi-Process Service (MPS) v3, enabling weighted timeslicing and better GPU resource sharing. CUDA Tile now supports direct GPU-to-GPU communication via NVLink and NVSwitch, while CUDA Python 1.2 adds batched memory transfers and flexible CUDA Graph updates. The release also includes new AI inference algorithms in CCCL 3.5 and a public preview of Nsight Perf SDK for AI. Users must install the R620 driver branch separately, as drivers are no longer bundled with the toolkit.

## Key points

- CUDA 13.5 adds general availability for NVIDIA Vera Rubin architecture and Windows on Arm support for DGX Station
- New driver modes (WDDM, MCDM) replace TCC mode for Rubin GPUs, improving GPU scheduling and resource management
- CUDA Tile enables direct GPU communication via NVLink/NVSwitch, and CUDA Python 1.2 introduces batched memory transfers

## Why it matters

The update accelerates AI and high-performance computing on NVIDIA GPUs, with Vera Rubin support and better multi-GPU coordination. Developers can optimize workload distribution and reduce resource contention, benefiting data centers and AI research.
