Cuda Driver Release News Exclusive -

Since CUDA 6, Unified Memory has relied on the driver manually migrating data. The new driver leak shows a hardware-assisted page fault engine integrated directly into the scheduler.

Prior drivers preempted at the Thread Block (CTA) level. If a long kernel ran for 5ms, real-time tasks waited.

R570 changes:
The driver can pause individual warps (32 threads) inside a CTA and save/restore their register state. cuda driver release news exclusive

How to enable (no code change required, but must opt-in):

cudaStreamCreateWithFlags(&stream, cudaStreamNonBlocking);
cudaStreamSetAttribute(stream, cudaStreamAttrPreemptionMode, cudaStreamPreemptionWarpGranular);

Use case: Real-time audio processing + LLM inference on same GPU. Previously required MIG partitions. Now possible with 2% overhead. Since CUDA 6, Unified Memory has relied on

This is the painful but expected exclusive: R570 will be the last driver branch to support Maxwell (GM20x) and Pascal (GP10x) GPUs. Starting with R575 (expected Q3 2026), CUDA 13+ drivers will require compute capability 8.0 (Ampere) or higher for full features, and Turing (7.5) will be moved to a legacy branch.

For the millions still running GTX 1080 Ti or Tesla P100 accelerators, this is a sunset notice. New CUDA toolkit versions will still compile for these architectures, but driver-level optimizations — and critical security patches — will cease after 2027.
