A user benchmarked the LTX 2.5 video generation model on an NVIDIA CMP 170HX GPU, comparing its performance against an RTX 5090. The CMP 170HX, after a thermal unlock and water cooling, demonstrated competitive performance, particularly in longer video generations where the 5090 encountered out-of-memory errors. The user plans to sell their 5090 due to concerns about RMA denial and the successful implementation of the 170HX. AI
