About RTX A4000 GPU
The NVIDIA RTX A4000 was introduced in 2020 on the Ampere architecture. Its specification combines 6,144 CUDA cores with 16GB of GDDR6, which defines both the workloads it can run and the batch sizes it can hold.
Based on its 16GB memory capacity, the RTX A4000 is best evaluated for quantized language-model inference, image generation, and medium-sized training jobs. Always size the model, optimizer state, KV cache, and framework overhead together rather than choosing a GPU from core count alone.
GPUvec currently tracks 2 cloud listings for the RTX A4000, with the lowest observed hourly rate at $0.12. Prices and availability can change by provider, region, and instance configuration, so verify the final rate before starting a workload.
For software planning, the RTX A4000 combines 448 GB/s of memory bandwidth, CUDA compute capability 8.6, and a 8nm manufacturing process. Confirm the minimum CUDA, PyTorch, TensorFlow, or driver version required by your application before renting or purchasing hardware.
