A user on Reddit's r/LocalLLaMA forum is seeking advice on building a multi-GPU setup for running large language models locally. They are considering adding an NVIDIA 3090 to their existing setup of a 5070 Ti and two 5060 Ti cards, but are concerned about potential performance degradation when mixing different GPU architectures (Ampere and Blackwell) in frameworks like llama.cpp and vLLM. The user is weighing the benefits of the 3090's larger VRAM and memory bandwidth against potential performance hits and is exploring options like pipeline parallelism to optimize performance. AI
