RTX A4000 on TensorDock
Visit TensorDockTensorDock provides access to the NVIDIA RTX A4000, a 16GB Ampere architecture workstation GPU, through its innovative GPU marketplace model. This combination stands out for delivering extremely low spot prices on a professional-grade GPU optimized for visual computing and AI workloads. Stabilized by recent acquisition from Voltage Park, TensorDock ensures reliable inventory availability, minimizing disruptions common in spot markets. Ideal for ML engineers and data scientists handling smaller-scale model training, fine-tuning, inference, or visualization tasks where cost efficiency trumps raw datacenter-scale performance. Key value propositions include per-second billing for precise cost control, spot instances offering up to 70-80% savings over on-demand, and a diverse marketplace aggregating supply from multiple hosts. The RTX A4000's 6,144 CUDA cores, 192 Tensor cores, and features like RT cores deliver balanced FP32/FP16 performance (19.2/38.7 TFLOPS) with power efficiency under 140W, making it perfect for bursty, budget-conscious workflows without sacrificing professional reliability.
Why NVIDIA RTX A4000 on TensorDock?
Opt for TensorDock's RTX A4000 when prioritizing the lowest spot prices on a capable workstation GPU. The marketplace model aggregates global supply, driving down costs while Voltage Park's acquisition stabilizes inventory for consistent availability. This complements the A4000's strengths in efficient, single-GPU ML tasks like prototyping, inference on 16GB models, or visual AI pipelines. Per-second billing eliminates waste on short jobs, and spot instances enable aggressive savings (often sub-$0.20/hour). Unlike rigid datacenter providers, TensorDock's flexibility suits variable workloads, with quick provisioning and diverse host options enhancing the A4000's plug-and-play workstation heritage for rapid iteration.

Performance Notes
On TensorDock, the RTX A4000 delivers solid Ampere performance: ~19.2 TFLOPS FP32, ~38.7 TFLOPS FP16 with sparsity, suiting fine-tuning of mid-sized LLMs or vision models within 16GB VRAM. Expect host-dependent factors—network bandwidth typically 10-25Gbps, NVMe storage 1-4TB, but varies by marketplace host. Multi-GPU scaling possible in 2-4x configs on select instances, though PCIe interconnects limit to NVLink-free bandwidth (~32-64GB/s). Pre-installed NVIDIA drivers and CUDA support ML frameworks out-of-box. Known limitations: not datacenter-optimized like A100/H100, so lower inter-GPU efficiency; spot interruptions possible. Specific TensorDock benchmarks sparse—test for your workload as host variability impacts consistency.
