Can Desktop PC · GeForce RTX 5070 Ti · 32 GB RAM run Gemma 4 26B-A4B?
16 GB VRAM + 32 GB RAM · 896 GB/s memory bandwidth · Gemma 4 26B-A4B has 25.8B parameters (3.8B active per token).
Short answer
Yes, excellent for chat; borderline for 64K-token documents.
Best quantization for chat: Q3_K_M (12 GB of weights) on Ollama. Generation: 230–310 tok/s, leaving about 2.0 GB free for your other apps.
How it rates for each workload
Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.
