Any one try any of this on a few 7900xtx (or familiarity with this hardware and platform)? I've just purchased 6 for some small-scale experimentation. I'm thinking the next machine I'll use AMD Radeon PRO W7900 (to get 128 GB VRAM / machine).
- almostgotcaught 2y agoJust export HSA_OVERRIDE_GFX_VERSION=11.0.0 and things should mostly work. Off the top of my head, some of the fp8 types aren't supported but <shrug>
- mjburgess 2y agoThanks -- I don't need everything to work, just enough to explore the platform and develop some realistic prototypes which can be moved on to probably the Radeon PROs.
- almostgotcaught 2y agoI run a large test suite daily (~30000) meant for MI300 on my local 7900. I don't keep track of fails outside of a specific few tests that I'm interested in but in general I get about 70-80% passing.
- slavik81 2y agoThe RX 7900 XTX and Radeon PRO W7900 are already 11.0.0. That override is unnecessary.
- fngarrett 2y agoWe have a dual W7800 system in-house as our `gfx1100` rig. I'll try to install and run through the tests sometime this week.
- manjunaths 2y agoI have a 7900 GRE, which is the same except less memory. I run Gemma 3, LLama 3.1, the QwQ models and the DeepSeek distilled models using llama.cpp. They run fine, I especially like the new Gemma3-27b-Q6 (20 GB model), I get 2 tok/s on it. I have also run Hunyuan3d-2 and generated 3d models. You would've to separate out the model generation and texture generation phase, but it works. I run ComfyUI and bootleg gguf models. This is all on windows. Now even WSL2 works, so I am using Ubuntu-24.04 on Windows 11 to run Hunyuan3D-2. For LLMs, llama.cpp native binaries are available. Everything just works out of the box.
