Can the RTX 4070 Laptop 8 GB run Krea 2 (Turbo)?
Not at full quality. The 16-bit and 8-bit files are too big for the RTX 4070 Laptop 8 GB; the largest that fits is Q2_K (4.9 GB).
Q2_K (4.9 GB) fits with only 0.5 GB to spare (about 7.5 GB of 8 GB). Quality: heavy loss; a last resort. For better quality, Q3_K_M (6.0 GB) also runs, with about 0.6 GB spilling into system RAM - a little slower, still practical.
Also try the FP8 file (13.1 GB) on this GPU. It does not fit entirely, but a current ComfyUI streams the overflow from RAM and native 8-bit files often beat a small GGUF that does fit. Dynamic VRAM →

03Measured and reported results
Nobody has sent measured numbers for this pair yet. If you run Krea 2 on a RTX 4070 Laptop 8 GB, send your time per image and peak VRAM and it will appear here, credited.
04With more VRAM
With 16 GB you could run Krea 2 at 8-bit or better (FP8, 13.1 GB) with no offloading: for example on the RTX 5080 16 GB, RTX 5070 Ti 16 GB, RTX 5060 Ti 16 GB.

05About the RTX 4070 Laptop 8 GB
The RTX 4070 Laptop 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.) As a laptop GPU it runs at a lower power limit than desktop cards (35–115 W depending on the laptop). The memory verdicts are the same; speed depends heavily on how much power the laptop maker allows.

06Questions
How much VRAM does Krea 2 need?
Around 7.5 GB with the smallest file (Q2_K) and 15.7 GB with an 8-bit file (FP8). The full 16-bit file needs about 28.9 GB.
Which Krea 2 file should I download for the RTX 4070 Laptop 8 GB?
Q2_K (4.9 GB) from vantagewithai/Krea-2-Turbo-GGUF. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
FP8 or Q8_0 for Krea 2 on the RTX 4070 Laptop 8 GB?
FP8 (13.1 GB): the RTX 4070 Laptop 8 GB computes it natively, while Q8_0 (13.7 GB) is unpacked on the fly.
How much do I need to download for Krea 2 on the RTX 4070 Laptop 8 GB?
10.4 GB: krea2_turbo-Q2_K.gguf, qwen3vl_4b_fp8_scaled.safetensors, qwen_image_vae.safetensors.
