GPUs have mature software stacks such as CUDA, cuDNN and NCCL, while NPUs mostly rely on vendor-proprietary SDKs (such as Ascend's CANN or the TPU's XLA path), and their cross-platform portability and operator coverage are far inferior to those of GPUs.

UnverifiedOpen-source isolation tools from vendors such as NVIDIA are typically designed with custom isolation strategies targeting the specifics of GPU workloads (such as CUDA driver access and video memory management), which general-purpose container solutions struggle to cover.76% similarUnverifiedGPUs have a large number of general-purpose compute cores and can be flexibly scheduled through programming models such as CUDA, making them naturally suited to the frequent matrix operations and gradient backpropagation in training; NPUs, by contrast, are dedicated chips customized for neural network inference, typically using systolic arrays or TPU-like dataflow architectures, highly optimized for fixed operators, but with closed programming models and limited support for dynamic computation graphs, making it traditionally difficult for NPUs to carry training workloads.75% similarUnverifiedDeep learning toolchains that depend on CUDA are highly tied to NVIDIA GPUs, while Windows ARM devices typically come equipped with Qualcomm Adreno GPUs or integrated NPUs.75% similarUnverifiedVKORE's functional positioning is analogous to what CUDA is to NVIDIA GPUs, sitting between application-layer ML frameworks and NPU hardware, but the specific implementation details (whether it includes a compiler, kernel libraries, runtime scheduler) have not been disclosed.74% similarVerifiedNVIDIA's software stack from the bottom layer to the application layer includes CUDA, cuDNN, cuBLAS, TensorRT, TensorRT-LLM, Triton Inference Server, and NIM.74% similar
