Can the RTX 4060 Ti 8 GB run SDXL 1.0?
Yes, but only just: 16-bit leaves 0.9 GB free on the RTX 4060 Ti 8 GB.
16-bit (6.9 GB) fits with only 0.9 GB to spare (about 7.1 GB of 8 GB).

One file: the checkpoint already contains the text encoders and the VAE. Sizes from Hugging Face, 2026-10-01.

“Needed” adds 1.2 GB of working memory for SDXL and a 0.8 GB reserve. Sizes 2026-10-01. The 6.94 GB checkpoint also holds the two text encoders and the VAE. During sampling only the UNet (about 5.1 GB at 16-bit, 2.6B parameters) has to sit in VRAM, so that is the figure used for the 16-bit file.
03The text encoder
The text encoder is inside the checkpoint, so there is nothing extra to download.
04Measured and reported results
Nobody has sent measured numbers for this pair yet. If you run SDXL on a RTX 4060 Ti 8 GB, send your time per image and peak VRAM and it will appear here, credited.
05About the RTX 4060 Ti 8 GB
The RTX 4060 Ti 8 GB is an Ada Lovelace GPU with hardware FP8, so ComfyUI can compute Comfy-Org's FP8 files natively: small and fast. (Plain FP8 files use FP8 maths with the --fast fp8_matrix_mult option.)
