Three 32GB AMD R9700s for the price of one RTX 5090: a local LLM user's dilemma
MrHall · reddit · 2026-08-28
A long-time NVIDIA user with a 16GB RTX 5070 Ti is considering switching to AMD Radeon R9700 cards. The draw: three 32GB R9700s cost about as much as a single RTX 5090, and 32GB VRAM would end the constant trade-offs between quantization, speed, and context size. His hesitation is AMD driver and ecosystem support on Linux, where CUDA has always Just Worked. He asks for real-world experiences and trade-offs from those who made the switch.
