A developer has released MiniMax H3, an optimized version of a diffusion model for AMD GPUs, incorporating BlockCache, Sol-Attn, and Turbo features. Testing on an RX 7900 XTX showed significant speed improvements, with Sol-Attn reducing processing time by approximately 23 seconds for short Turbo runs. BlockCache proved beneficial for longer 20-step generation tasks, cutting down the time from over 6 minutes to around 4 minutes in some scenarios. AI
