Frequently Asked Questions: Google Gemma 4 26B MoE on NVIDIA GeForce RTX 4080 Super (16GB GDDR6X)
How much VRAM does Google Gemma 4 26B MoE need on NVIDIA GeForce RTX 4080 Super (16GB GDDR6X)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Google Gemma 4 26B MoE requires 20.23 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Google Gemma 4 26B MoE achieve on NVIDIA GeForce RTX 4080 Super (16GB GDDR6X)?
Based on NVIDIA GeForce RTX 4080 Super (16GB GDDR6X)'s 736 GB/s memory bandwidth, expected decode speed is approximately 33 tokens per second.
Can I expand context beyond 32K tokens?
Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
