Can I run Gemma 4 26B-A4B on AMD Ryzen AI Halo (128GB)?
Yes. Gemma 4 26B-A4B runs on AMD Ryzen AI Halo (128GB) at Q4_K_M (~19 GB of ~96 GB usable).
Runs at Q4_K_M using ~19 GB of ~96 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. AMD Ryzen AI Halo (128GB) leaves ~77 GB of headroom, room to step up to FP16 for higher quality.

FAQ
Can AMD Ryzen AI Halo (128GB) run Gemma 4 26B-A4B?
Yes. Gemma 4 26B-A4B runs on AMD Ryzen AI Halo (128GB) at Q4_K_M (~19 GB of ~96 GB usable).
How much memory does Gemma 4 26B-A4B need?
AMD Ryzen AI Halo (128GB) has room to spare. At Q4_K_M the weights are ~17.04 GB; with KV cache and runtime overhead, budget ~19 GB at a 4k context. It is a Mixture-of-Experts model (26.5B total / 3.8B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Gemma 4 26B-A4B on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
