Direct performance comparison between the A100 and RTX 4090 across 26 standardized AI benchmarks collected from our production fleet. Testing shows the A100 winning 11 out of 26 benchmarks (42% win rate), while the RTX 4090 wins 15 tests. All benchmark results are automatically gathered from active rental servers, providing real-world performance data.
For production API servers and multi-agent AI systems running multiple concurrent requests, the A100 is 23% faster than the RTX 4090 (median across 2 benchmarks). For Qwen/Qwen3-4B, the A100 achieves 826 tokens/s vs RTX 4090's 706 tokens/s (17% faster). The A100 wins 2 out of 2 high-throughput tests, making it the stronger choice for production chatbots and batch processing.
For personal AI assistants and local development with one request at a time, both the A100 and RTX 4090 deliver nearly identical response times across 8 Ollama benchmarks. Running gpt-oss:20b, the A100 generates 150 tokens/s while RTX 4090 achieves 183 tokens/s (18% slower). The A100 wins 1 out of 8 single-user tests, making the RTX 4090 the better choice for local AI development.
For Stable Diffusion, SDXL, and Flux workloads, both the A100 and RTX 4090 perform nearly identically across 12 benchmarks. Testing sd3.5-large, the A100 completes at 15 s/image vs RTX 4090's 58 s/image (285% faster). The A100 wins 6 out of 12 image generation tests, showing both GPUs are equally suitable for image generation.
For high-concurrency vision workloads (16-64 parallel requests), the A100 delivers 14% higher throughput than the RTX 4090 (median across 2 benchmarks). Testing llava-1.5-7b, the A100 processes 282 images/min vs RTX 4090's 217 images/min (30% faster). The A100 wins 1 out of 2 vision tests, showing both GPUs handle production vision workloads equally well.

Our benchmarks are collected automatically from servers having GPUs of type A100 and RTX 4090 in our fleet. Unlike synthetic lab tests, these results come from real production servers handling actual AI workloads - giving you transparent, real-world performance data.
We test both vLLM (High-Throughput) and Ollama (Single-User) frameworks. vLLM benchmarks show how A100 and RTX 4090 perform with 16-64 concurrent requests - perfect for production chatbots, multi-agent AI systems, and API servers. Ollama benchmarks measure single-request speed for personal AI assistants and local development. Models tested include Llama 3.1, Qwen3, DeepSeek-R1, and more.
Image generation benchmarks cover Flux, SDXL, and SD3.5 architectures. That's critical for AI art generation, design prototyping, and creative applications. Focus on single prompt generation speed to understand how A100 and RTX 4090 handle your image workloads.
Vision benchmarks test multimodal and document processing with high concurrent load (16-64 parallel requests) using real-world test data. LLaVA 1.5 7B (7B parameter Vision-Language Model) analyzes a photograph of an elderly woman in a flower field with a golden retriever, testing scene understanding and visual reasoning at batch size 32 to report images per minute. TrOCR-base (334M parameter OCR model) processes 2,750 pages of Shakespeare's Hamlet scanned from historical books with period typography at batch size 16, measuring pages per minute for document digitization. See how A100 and RTX 4090 handle production-scale visual AI workloads - critical for content moderation, document processing, and automated image analysis.
We also include CPU compute power (affecting tokenization and preprocessing) and NVMe storage speeds (critical for loading large models and datasets) - the complete picture for your AI workloads.
The TAIFlops (Trooper AI FLOPS) score shown in the first row combines all AI benchmark results into a single number. Using the RTX 3090 as baseline (100 TAIFlops), this score instantly tells you how A100 and RTX 4090 compare overall for AI workloads. Learn more about TAIFlops →
Note: Results may vary based on system load and configuration. These benchmarks represent median values from multiple test runs.
