V100 vs RTX 3090 - GPU Benchmark Comparison

Direct performance comparison between the V100 and RTX 3090 across 12 standardized AI benchmarks collected from our production fleet. Testing shows the V100 winning 0 out of 12 benchmarks (0% win rate), while the RTX 3090 wins 12 tests. All 12 benchmark results are automatically gathered from active rental servers, providing real-world performance data rather than synthetic testing.

LLM Inference Performance: V100 17% slower

In language model inference testing across 4 different models, the V100 is 17% slower than the RTX 3090 on average. For qwen3:8b inference, the V100 reaches 99 tokens/s while the RTX 3090 achieves 122 tokens/s, making the V100 noticeably slower with a 19% deficit. Overall, the V100 wins 0 out of 4 LLM tests with an average 17% performance difference, making the RTX 3090 the better option for LLM inference tasks.

Image Generation Performance: V100 23% slower

Evaluating AI image generation across 8 different Stable Diffusion models, the V100 is 23% slower than the RTX 3090 in this category. When testing sd3.5-medium, the V100 completes generations at 43 s/image while the RTX 3090 achieves 31 s/image, making the V100 significantly slower with a 28% deficit. Across all 8 image generation benchmarks, the V100 wins 0 tests with an average 23% performance difference, making the RTX 3090 the better choice for Stable Diffusion, SDXL, and Flux workloads.

About These Benchmarks of V100 vs RTX 3090

Our benchmarks are collected automatically from servers having gpus of type V100 and RTX 3090 in our fleet using standardized test suites:

LLM Inference (Ollama & VLLM): Measures tokens per second of V100 compared to RTX 3090 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 V100 compared to RTX 3090
CPU: Single-core and multi-core operations per second representing GPU Servers you can rent with V100 or RTX 3090
NVMe: Read and write speeds in MB/s for storage performance on GPU Servers typically equipped with V100 or RTX 3090

Note: V100 and RTX 3090 AI Benchmark Results may vary based on system load, configuration, and specific hardware revisions. These benchmarks represent median values from multiple test runs of V100 and RTX 3090.
