A100 SXM4 80GB on Vast.ai

Visit Vast.ai

Vast.ai offers the NVIDIA A100 SXM4 80GB, a top-tier Ampere architecture GPU with 80GB HBM2e VRAM, tailored for demanding AI, ML, and HPC workloads in data centers. This enterprise-grade GPU delivers up to 19.5 TFLOPS FP64, 312 TFLOPS TF32, and exceptional multi-instance GPU (MIG) support for efficient resource partitioning. On Vast.ai's decentralized marketplace, it stands out for providing access at the absolute lowest costs—often under $1/hour—via competitive peer-hosted rentals and spot instances. Ideal for ML engineers running large language models, fine-tuning, or distributed training experiments, this combo excels in cost-sensitive scenarios where hyperscalers like AWS or GCP prove prohibitively expensive. Unique granular filters like DLPerf/$ (deep learning performance per dollar) enable precise selection of high-value instances. While host variability introduces some unpredictability, the platform's vast inventory ensures quick availability for scalable, budget-optimized deployments.

Why NVIDIA A100 SXM4 80GB on Vast.ai?

Choose Vast.ai for NVIDIA A100 SXM4 80GB to access enterprise-grade 80GB VRAM at rock-bottom prices through its decentralized P2P marketplace, where hosts compete to offer rates as low as $0.50-$1.00/hour versus $3+/hour on traditional clouds. Spot (interruptible) instances slash costs further for fault-tolerant workloads. Granular search filters—DLPerf/$, reliability scores, and exact GPU configs—help pinpoint optimal hosts matching your needs, like high-bandwidth NVLink for multi-GPU. This complements the A100's prowess in training massive models (e.g., 70B+ params) by democratizing high-memory GPU access for solo researchers, startups, and experimenters prioritizing cost over managed services.

Performance Notes

Expect flagship A100 SXM4 80GB performance: 624 GB/s memory bandwidth, NVLink support for multi-GPU scaling up to 8-way. On Vast.ai, outcomes vary by host—network speeds range from 1-100 Gbps, storage from SSD to NVMe (often 1-10TB), and interconnects may lack full DGX uniformity. Single A100 suits inference/fine-tuning of large models; multi-GPU setups scale well for distributed training via NCCL. Benchmarks like MLPerf show near-native speeds on premium hosts, but verify DLPerf scores. Unknowns include consistent uptime and exact cooling; test short rentals first. Overall, strong value for cost-sensitive ML but monitor for host-specific quirks.
