AMD Strix Halo (128GB)

The AMD Strix Halo (128GB) has 128 GB VRAM and 256 GB/s memory bandwidth. It can run 58 of our 70 tracked models natively in VRAM at 8k context.

With 128 GB LPDDR5X, the AMD Strix Halo (128GB) is a laptop-tier GPU that can run 58 models natively. It handles 70B-class models at Q4 quantization.

AMD Strix Halo (128GB): 2025 unified memory APU with 128GB LPDDR5X at 256 GB/s. RDNA 3.5 architecture.

70B at Q4 native. 405B at Q2 with offload. ~5-10 t/s for 7B.

Vulkan via llama.cpp works cross-platform. ROCm Linux experimental. Unified memory helps but bandwidth is limiting.
