Is 12GB VRAM Enough? Choosing GPUs for Local LLM Deployment
rettdit · reddit · 2026-08-02
The poster discusses whether it's worth upgrading from 12GB to 16GB of VRAM for running local AI models. Most modern models, including large ones like WAN and LTX, have quantized versions that run fine on 12GB. The "can it run?" issue is mostly solved, shifting the bottleneck to processing speed.
Consequently, the poster is debating whether to get the faster RTX 4070 Super 12GB or the RTX 5060 Ti 16GB for the extra VRAM headroom, even though 12GB seems sufficient for now.
