Om disse benchmarks af RTX 3090 vs RTX 4090

Vores benchmarks indsamles automatisk fra servere med GPU'er af typen RTX 3090 og RTX 4090 i vores flåde. I modsætning til syntetiske labtests kommer disse resultater fra faktiske produktionsservere, der håndterer faktiske AI-workloads - hvilket giver dig gennemsigtige, real-world performance data.

LLM Inferens Benchmarks

Vi tester begge vLLM (Høj-gennemstrømning) og Ollama (Enkeltbruger) frameworks. vLLM benchmarks show how RTX 3090 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, og mere.

Billedgenereringsbenchmarks

Billedgenererings benchmarks dækker 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 RTX 3090 and RTX 4090 handle your image workloads.

Vision AI Benchmarks

Vision benchmarks tester multimodal og dokumentbehandling med høj samtidige belastning (16-64 parallel anmodninger) ved hjælp af virkelige testdata. LLaVA 1.5 7B (7B parameter Vision-Language Model) analyserer et fotografi af en ældre kvinde i et blomsterfelt med en golden retriever, og tester scene forståelse og visuel ræsonnement med en batchstørrelse på 32 for at rapportere billeder pr. minut. TrOCR-base (334M parameter OCR-model) behandler 2.750 sider af Shakespeares Hamlet, der er scannet fra historiske bøger med periodisk typografi ved batchstørrelse 16, og måler sider per minut for document digitization. See how RTX 3090 and RTX 4090 handle production-scale visual AI workloads - critical for content moderation, document processing, and automated image analysis.

Systemydelse

Vi inkluderer også CPU-ydelse (der påvirker tokenisering og forbehandling) og NVMe-lagringshastigheder (afgørende for indlæsning af store modeller og datasæt) – det fulde billede af dine AI-arbejdsbelastninger.

TAIFlops Score

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 RTX 3090 and RTX 4090 compare overall for AI workloads. Læs mere om TAIFlops →
