A100 vs RTX A4000 - GPU Benchmark Comparison

Direct performance comparison between the A100 and RTX A4000 across 14 standardized AI benchmarks collected from our production fleet. Testing shows the A100 winning 14 out of 14 benchmarks (100% win rate), while the RTX A4000 wins 0 tests. All 14 benchmark results are automatically gathered from active rental servers, providing real-world performance data rather than synthetic testing.

LLM Inference Performance: A100 109% faster

In language model inference testing across 4 different models, the A100 is 109% faster than the RTX A4000 on average. For llama3.1:8b inference, the A100 achieves 154 tokens/s compared to RTX A4000's 76 tokens/s, making the A100 substantially faster with a 103% advantage. Overall, the A100 wins 4 out of 4 LLM tests with an average 109% performance difference, making it the stronger choice for transformer model inference workloads.

Image Generation Performance: A100 244% faster

Evaluating AI image generation across 10 different Stable Diffusion models, the A100 is 244% faster than the RTX A4000 in this category. When testing sd3.5-medium, the A100 completes generations at 6.8 s/image compared to RTX A4000's 34 s/image, making the A100 substantially faster with a 405% advantage. Across all 10 image generation benchmarks, the A100 wins 10 tests with an average 244% performance difference, establishing it as the preferred GPU for Stable Diffusion, SDXL, and Flux deployments.

About These Benchmarks of A100 vs RTX A4000

Our benchmarks are collected automatically from servers having gpus of type A100 and RTX A4000 in our fleet using standardized test suites:

LLM Inference (Ollama & VLLM): Measures tokens per second of A100 compared to RTX A4000 for LLM inference using various models (Llama, Qwen, etc.) on both Ollama and VLLM with FP8 quantization
Image Generation: Measures images per minute and seconds per image for AI image generation on the A100 compared to RTX A4000
CPU: Single-core and multi-core operations per second representing GPU Servers you can rent with A100 or RTX A4000
NVMe: Read and write speeds in MB/s for storage performance on GPU Servers typically equipped with A100 or RTX A4000

Note: A100 and RTX A4000 AI Benchmark Results may vary based on system load, configuration, and specific hardware revisions. These benchmarks represent median values from multiple test runs of A100 and RTX A4000.
