This Reddit thread from r/StableDiffusion discusses the trade-offs between purchasing an RTX 5080 or 5090 laptop for running ComfyUI locally versus using a remote desktop/cloud GPU setup for Stable Diffusion workflows. Key considerations likely include performance concerns with laptop RTX 50-series GPUs in ComfyUI, as some users have reported them running significantly slower than desktop equivalents , as well as the hardware differences between the two cards — the RTX 5090 offering 32 GB of GDDR7 memory versus the RTX 5080's 16 GB, with the latter being more power-efficient for workstation use . The discussion also likely touches on remote desktop drawbacks such as CPU bottlenecks and network latency affecting responsiveness, with potential mitigations like optimizing RDP encoding .
