Playground v2 vs Stable Diffusion XL 1.0 for text-to-image generation

This post compares Playground v2 and Stable Diffusion XL 1.0 for text-to-image generation, evaluating quality, speed, and GPU requirements. It details head-to-head image quality comparisons across various prompts, noting Playground v2's consistent aesthetic and SDXL's variety. Inference speed is found to be comparable for standard 50-step runs on an A10G GPU, with both models fitting on 16GB VRAM GPUs. The post also discusses potential optimizations for Playground v2 based on SDXL's architecture and recommends specific GPUs (T4, A10, A100) based on cost and performance tradeoffs.
