RIP my 1080 TI.
Does anyone know what specific feature they need which 20+ cards have and older ones don't?
- binarymax 3y agoNot enough RAM in your 1080TI Edit - it’s not the RAM. 1080TI has 11GB and this press release says it requires 8. So I’m going to speculate that it’s because 1080 lacks tensor cores compared to the 20x’s Turing architecture
- nolok 3y agoFunny knowing the stupidity nvidia is pulling with the 4xxx series regarding ram amount.

- cma 3y agoSince it is now split into two models to do the generation, you could load one and do the first stage of a bunch of images, then load the second and complete them, with half the vram usage.
- ShamelessC 3y agoI believe the HF pipeline can do this already and I assume each stage uses more than 4 GB vram. There are other tricks they open source community will come up with though.
- brucethemoose2 3y ago8 bit (and 4 bit?) quantization is low hanging fruit, assuming its not already running in 8 bit. An 8GB requirement kinda sounds like they have already quantized the model though.
- bogwog 3y agoThe post says it only needs 8GB, and my 1080 has 11GB.
- dist-epoch 3y agoRTX 20 have tensor cores. 1080 do not.
- brucethemoose2 3y agoMy guess is low precision support, or some newer ops Pascal does not support in a custom CUDA kernel.
- Filligree 3y agoLow precision support, almost certainly. SD 1.5 needs almost twice the memory on a 10xx card as on 20xx, because you can't use FP16; a triple bummer, since that makes it even slower (memory bandwidth!) and you don't have as much to begin with.
