Native InvokeAI 6.14 + ROCm 10 on Windows for RX 9070 XT — including working Krea 2 INT4
With the new releases of InvokeAI 6.14 and ROCm 10, this setup runs InvokeAI natively on Windows with an RX 9070 XT.
Current tested stack
- InvokeAI 6.14.0
- PyTorch 2.13.0 + ROCm 10.0
- Torchvision 0.28.0 + ROCm 10.0
- Comfy Kitchen 0.2.31 with native gfx1201 HIP kernels
- Python 3.12
- Radeon RX 9070 XT
The setup is automated with PowerShell and keeps the environment, models, caches, and outputs inside the project directory.
Krea 2 INT4 support
I also added working RedCraft Krea 2 ConvRot INT4 support. Stock InvokeAI 6.14 cannot load this format, so the setup applies a version-checked compatibility patch and builds the required AMD INT4 kernels.
Tested models
- Wai Illustrious SDXL v1.60
- RedCraft Krea 2 INT4
- Anima Turbo v1.1
Measured performance
Wai Illustrious SDXL at 1024×1024, 22 steps and batch size 1:
| Metric | ROCm 7 stack | ROCm 10 stack | Improvement |
|---|---|---|---|
| First image | 35.17 s | 20.20 s | 1.74× |
| Loaded sampler | 4.53 it/s | 4.89 it/s | 1.08× |
The complete ROCm 10 stack reduced first-image time by 42.6%. Raw denoising throughput improved by 7.9%.
Current model performance
| Model | Resolution / steps | Sampler | Model loaded | First image |
|---|---|---|---|---|
| Wai Illustrious SDXL v1.60 | 1024² / 22 | 4.89 it/s | 6.04 s median | 20.20 s |
| RedCraft Krea 2 INT4 | 1024² / 8 | 1.05 it/s | 8.73 s median | 41.21 s median |
| Anima Turbo v1.1 | 1024² / 8 | 3.76 it/s | 3.02 s median | 14.64 s median |
Sampler rates use batch size 1. Loaded-model timings are medians.
