NVIDIA A10 vs. A100: Best GPUs for Stable Diffusion Inference

When it comes to AI inference workloads like Stable Diffusion, choosing the right GPU is essential for delivering both performance and cost-efficiency. Two leading contenders in NVIDIA's Ampere architecture lineup are the NVIDIA A10 and NVIDIA A100. Each GPU targets different workloads, but which one is better suited for Stable Diffusion inference? Let’s dive into the details and uncover how these GPUs compare in performance, memory, and overall value for AI cloud environments.


Overview of Ampere GPUs

NVIDIA’s Ampere architecture, which powers both the A10 GPU and A100 GPU, has revolutionized AI performance with its Tensor Cores, Multi-Instance GPU (MIG) technology, and improved floating-point operations. Designed to handle a wide range of workloads, the Ampere series serves both data centers and workstations, enabling faster training, inference, and real-time analytics.

While both the A10 and A100 leverage Ampere technology, they cater to different AI workloads:

  • NVIDIA A10: Positioned as a cost-effective solution for AI inference and cloud-based applications.

  • NVIDIA A100: Designed for high-performance computing, handling massive ML models and deep learning training at scale.

Key Features of the Ampere Architecture

  • Third-Generation Tensor Cores: Provide better support for sparsity, accelerating both dense and sparse matrix computations used in AI models.

  • Multi-Instance GPU (MIG): Allows partitioning of the GPU into multiple smaller instances, increasing efficiency for multiple workloads.

  • Unified Memory Architecture: Improved memory management between GPU and CPU, enhancing inference latency.

Both the A10 and A100 GPUs are compatible with AI Cloud platforms, making them viable for Stable Diffusion inference, but their specific capabilities impact performance differently.

From the above comparison, it is clear that the NVIDIA A100 has a significant advantage in memory bandwidth, which plays a vital role in AI model inference. However, the A10 GPU provides a more power-efficient solution while still delivering excellent inference performance.


VRAM and Memory Type: GDDR6 vs. HBM2e

One of the key differences between the A10 and A100 GPUs lies in their memory type and configuration:

  1. A10 GPU:

    • Equipped with 24 GB GDDR6 memory, which offers high capacity for handling moderately large models like Stable Diffusion.

    • GDDR6 is optimized for inference tasks where memory speed is less critical than in training workloads.

  2. A100 GPU:

    • Available in 40GB and 80GB variants, both using HBM2e memory for ultra-high bandwidth.

    • The higher bandwidth enables faster access to data, which is crucial for large-scale deep learning models and complex computations.

For Stable Diffusion inference, having sufficient VRAM is essential since the model can consume 10–12 GB of memory, leaving little room for input images and intermediate outputs. While the A10 GPU has enough memory for most Stable Diffusion models, the A100’s 40GB or 80GB memory offers more flexibility for running multiple parallel inferences or handling larger batch sizes.


Performance Comparison: NVIDIA A10 vs. A100 for Stable Diffusion Inference

Latency and Throughput

In AI inference, latency (response time) and throughput (how many inferences can be processed per second) are two crucial metrics. Stable Diffusion inference involves running transformer models and multiple attention layers, which demand fast memory access and parallel compute power.

  • A10 GPU Performance:

    • With 24 GB of GDDR6 and 31.2 TFLOPS FP32 performance, the A10 can handle Stable Diffusion inference with minimal bottlenecks.

    • It works best when used for inference workloads with small to medium batch sizes (e.g., batch size 1-4).

    • It also consumes just 150W, making it highly power-efficient for AI Cloud deployments that prioritize cost control.

  • A100 GPU Performance:

    • The A100 excels in high-throughput scenarios, such as batched inference with batch sizes of 8 or higher.

    • With HBM2e memory and MIG support, the A100 allows running multiple instances of Stable Diffusion in parallel, offering better resource utilization in AI Cloud settings.

    • The 40GB and 80GB configurations ensure that larger models or custom versions of Stable Diffusion (such as those with high-resolution images) run without memory constraints.


Cost Considerations: Which GPU Offers Better Value for AI Cloud?

When deploying GPUs in an AI Cloud environment, both performance and cost need to be evaluated.

  1. NVIDIA A10 GPU:

    • Lower upfront cost compared to the A100.

    • More power-efficient, with a 150W power envelope.

    • Ideal for entry-level AI inference tasks, such as Stable Diffusion for smaller workloads, real-time applications, or where cost-efficiency is critical.

    • Available on shared cloud instances for developers looking to experiment with smaller models.

  2. NVIDIA A100 GPU:

    • Significantly higher cost, but delivers exceptional performance for larger-scale AI models and heavy workloads.

    • Higher operational cost due to 400W power consumption.

    • Best suited for data centers, AI Cloud providers, and enterprises running multiple Stable Diffusion instances or requiring high throughput.

    • Works well for customers who need to scale their models for production-level AI inference.

In summary, the A10 GPU offers better cost-efficiency for small-scale and experimental deployments, while the A100 shines for production environments where performance is paramount.


Which GPU Is Better for Stable Diffusion Inference?

Choosing between the NVIDIA A10 and NVIDIA A100 for Stable Diffusion inference depends on your specific needs.

  • Choose NVIDIA A10 if:

    • You need cost-effective AI inference with moderate batch sizes.

    • Power efficiency is a priority in your AI cloud infrastructure.

    • You plan to use shared instances in the cloud for smaller workloads.

  • Choose NVIDIA A100 if:

    • You require high-performance inference with large batch sizes or multiple concurrent requests.
