A30 24GB

Specs, explained

Used for AI inference, training and HPC

1. 0124 GB of HBM2 memory

   VRAM

   24 GB

   Memory type

   HBM2

   Memory bandwidth

   0.933 TB/s

   HBM (High Bandwidth Memory) is stacked in layers and sits right next to the processor on the same package. That short, wide path is what gives accelerators with HBM their memory bandwidth, so they are usually chosen for work limited by how fast data reaches the cores, such as large-model inference and HPC simulation.

   VRAM is the working space on the card. Model weights, activations and datasets have to fit in it, or be split across several GPUs. Rule of thumb for the weights alone at 16-bit precision (about 2 GB per billion parameters): up to roughly 12 billion parameters, before activations and cache. This is arithmetic on the recorded VRAM, not a benchmark.

2. 02Ampere architecture

   Architecture

   Ampere

   Launch year

   2021

   Lifecycle status

   Previous

   Ampere brought third-generation Tensor Cores, TF32 precision and Multi-Instance GPU (MIG) to its data-center parts. (General context about the architecture, not a statement about this specific card.)

   Launched in 2021. Kovara's records list it as a previous-generation part.

3. 03Built to scale across GPUs

   NVLink

   Supported

   MIG

   Supported

   Form factor

   PCIe dual-slot FHFL

   TDP

   165 W

   NVLink is a direct GPU-to-GPU link. Where it is supported, GPUs in the same server can exchange data faster than over PCIe alone, which matters when one training job is spread across several GPUs.

   Multi-Instance GPU (MIG) can divide one physical GPU into isolated slices, each with its own memory and compute, so several smaller workloads can share a card.

   PCIe cards slot into standard server and workstation expansion slots, which suits a wide range of systems.

   TDP is the rated thermal design power: the planning figure for power delivery and cooling in a server.

4. 04What it is used for

   Primary use (recorded)

   AI inference / training / HPC

   These are the uses Kovara has recorded for this part. The notes explain the workload in general terms; they are not performance claims.

   • AI inferenceRunning a trained model to answer requests. Memory capacity, latency and cost per request are the usual concerns.
   • trainingTeaching a model from data. Usually the most compute- and memory-hungry phase, often spread across many GPUs.
   • HPCScientific and engineering simulation, where numerical precision and memory bandwidth matter.
