Memory math: weights + context vs budget

Weights take 6.5 GB. Context costs extra KV-cache on top — this is where long-context sessions break on cards that technically fit the weights.

KV-cache figures assume an fp16 cache, the llama.cpp/Ollama default. Standard GQA models use a size-class estimate (8 KV heads x 128 head dim class); hybrid linear-attention models (Qwen3.5/3.6, Qwen3-Next) use the exact per-token cost from their published config, since only their sparse full-attention layers cache KV. A q8_0 KV cache roughly halves either figure. Estimates, not measurements.

Qwen3 8B on RTX 4070 Ti SUPER: FAQ

Can the NVIDIA GeForce RTX 4070 Ti SUPER run Qwen3 8B?

Yes. Qwen3 8B (Q4_K_M) loads in about 6.5 GB and the RTX 4070 Ti SUPER offers 14.4 GB of usable VRAM, leaving headroom for context. Expect at roughly 72 tokens/sec (est.).

How much VRAM does Qwen3 8B need?

About 6.5 GB for the weights at Q4_K_M, plus KV-cache for context: roughly 2.0 GB extra at 16k tokens. The RTX 4070 Ti SUPER budget is 14.4 GB (16 GB x 90%).

What is the best quantization of Qwen3 8B for the RTX 4070 Ti SUPER?

Stick with the Q4_K_M build at 6.5 GB — every heavier quant exceeds the 14.4 GB usable VRAM.

What GPU do I need to run Qwen3 8B comfortably?

The RTX 4070 Ti SUPER already runs Qwen3 8B comfortably. Larger cards only buy you longer context or a heavier quant.
