Architecture & Throughput Transparency: Single-user decode speed (~0 tok/s) is memory-bandwidth bound at batch size = 1 on NVIDIA RTX 4070 Ti Super (16GB) (672 GB/s). Prompt prefill / TTFT (~0 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).
MoE Memory vs Speed Architecture: While decode throughput scales with the active parameter count (22B parameters streamed per token), all 235B parameters must be resident in VRAM so the dynamic router can route tokens to any expert layer.

FAQ & Reference

Frequently Asked Questions: Qwen 3.8 235B-A22B MoE on NVIDIA RTX 4070 Ti Super (16GB)

How much VRAM does Qwen 3.8 235B-A22B MoE need on NVIDIA RTX 4070 Ti Super (16GB)?

At standard 4-bit quantization (Q4_K_M) with 32K context, Qwen 3.8 235B-A22B MoE requires 149.84 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will Qwen 3.8 235B-A22B MoE achieve on NVIDIA RTX 4070 Ti Super (16GB)?

Based on NVIDIA RTX 4070 Ti Super (16GB)'s 672 GB/s memory bandwidth, expected decode speed is approximately 0 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.
