RTX 5070 Ti vs RTX 3090: VRAM vs. New Tech for Local LLMs

By PulseAugur Editorial · [1 sources] ·

A comparison between the new NVIDIA RTX 5070 Ti and a used RTX 3090 for running large language models (LLMs) locally reveals distinct advantages for each. The RTX 5070 Ti, priced at $750, offers 16GB of GDDR7 VRAM and newer architecture, making it suitable for smaller models up to 13B parameters and general computing tasks. The used RTX 3090, available for around $600, provides a larger 24GB of GDDR6X VRAM, which is crucial for running larger models like 34B parameters and offers a path to multi-GPU setups for even larger models.
