Fast image generation with SD, SDXL, and Flux
Quick Answer: For most users, the RTX 4070 Ti Super 16GB ($750-$850) offers the best balance of VRAM, speed, and value. Budget builders should consider the RTX 3060 12GB ($250-$350), while professionals should look at the RTX 4090 24GB.
Image generation is GPU-intensive and benefits from both VRAM (for model weights and batch size) and raw compute power. SDXL needs 10GB+ VRAM, Flux needs 12GB+. Here are our tested recommendations.
