Used NVIDIA A100s - Information:

The NVIDIA A100 Tensor Core GPU delivers unprecedented acceleration at every scale, powering the world's highest-performing elastic data centers for AI, data analytics, and HPC applications. Providing up to 20X higher performance over the previous Volta™ generation, the A100 can efficiently scale up or be partitioned into seven isolated GPU instances with Multi-Instance GPU (MIG).

This creates a unified platform that dynamically adjusts to shifting workload demands. Supporting a broad range of math precisions, the A100 80GB model doubles GPU memory and offers the world’s fastest memory bandwidth at 2 terabytes per second, accelerating solutions for the largest models and datasets.

Built on the NVIDIA Ampere architecture, the A100 is equipped with Tensor Cores that are tailored for matrix multiplication operations, a fundamental component of AI model training and inference. With an impressive 6,912 CUDA cores and 40 GB of high-bandwidth memory (HBM2), the A100 delivers unprecedented computational power.

Frequently Asked Questions

ARE YOUR USED NVIDIA A100 GPUS FULLY TESTED BEFORE SALE?

Yes. Every A100 GPU is professionally tested to enterprise standards. All testing is done in-house at Alta Technologies.
HOW DOES THE PERFORMANCE OF A USED A100 GPU COMPARE TO A NEW ONE?

When properly refurbished, a used A100 delivers performance nearly identical to a new unit. We ensure full functionality, high bandwidth memory integrity, and accurate core performance.
WHAT IS THE EXPECTED LIFESPAN OF AN A100 GPU?

The A100 is engineered for enterprise workloads and often runs reliably for many years. Most come from environments similar to yours, which are supported and climate-controlled.
WHAT POWER AND COOLING SETUP DO I NEED FOR THESE GPUS?

Ensure your system supports the correct thermal design power: about 300W for PCIe and 400W for SXM. Proper airflow and power provisioning are essential for stable operation.
DO YOU OFFER DISCOUNTS FOR BULK PURCHASES OR RESALE?

Yes. We offer volume discounts for resellers, MSPs, and enterprise buyers. Contact us directly to receive a customized quote tailored to your project requirements.

Why Buy Used NVIDIA A100 GPUs?

Designed on the NVIDIA Ampere architecture, the A100 series delivers breakthrough acceleration for training and inference, supporting multi-instance GPU (MIG) partitioning and high-bandwidth HBM2e memory. When sourced through a trusted refurbisher like Alta Technologies, a used NVIDIA A100 offers the same transformative compute capabilities, at up to 80% cost savings over new, as supply becomes available.

Purchasing refurbished also supports sustainability goals by extending the life of premium hardware. At Alta, each unit goes through a multi-point inspection process, is cleaned and tested in a climate-controlled environment, and is confirmed for power, thermal, and performance benchmarks, helping IT professionals reduce costs without compromising reliability.

Our Selection of Used NVIDIA A100 GPUs

Alta offers two key models in our used NVIDIA A100 inventory: the PCIe and SXM versions, both with 80GB of high-bandwidth memory. These GPUs are ideal for data-intensive computing tasks like neural network training, large-scale inference, simulation workloads, and real-time analytics.

The PCIe version provides 80GB of HBM2e memory with a memory bandwidth nearing 2 terabytes per second, and is available in air-cooled or liquid-cooled configurations. It’s built for compatibility with a wide variety of standard servers.

The SXM version also offers 80GB of high-performance memory but delivers slightly higher bandwidth and is optimized for tightly integrated systems. With a higher thermal design power rating, it fits into specialized high-density GPU platforms and can be partitioned into seven MIGs for parallel workload isolation.

Both models are tested to ensure seamless integration and maximum uptime. Reach out to our team to explore which version best aligns with your infrastructure and workloads.

How to Choose the Right Used NVIDIA A100 GPU for Your Needs

Choosing the right A100 depends on hardware compatibility, deployment goals, and infrastructure readiness.

PCIe vs. SXM

PCIe models offer wider compatibility and easier deployment into standard rackmount servers.
SXM models deliver higher memory bandwidth and tighter integration—ideal for clustered compute environments with custom cooling solutions.

Single vs. Multi-GPU Setup Considerations

For AI inference, a single A100 may suffice.For training large models or parallel processing, multi-GPU setups offer significant throughput advantages. MIG support allows logical GPU partitioning—ideal for virtualized or containerized workloads.

Power & Cooling Requirements

PCIe (300W): Compatible with traditional air or liquid-cooled servers.
SXM (400W): Requires integrated cooling and power provisioning—commonly found in purpose-built AI infrastructure.

Alta’s team can help assess your environment and suggest tested and compatible upgrades tailored to your deployment.
