Can the RTX 4070 SUPER Run Qwen3 8B?
Runs
Yes. Qwen3 8B at Q4_K_M is a 5 GB download (Hugging Face file listing for unsloth/Qwen3-8B-GGUF), and the RTX 4070 SUPER has 12 GB of VRAM, leaving about 7 GB for the KV cache and runtime. Published runs put generation at a median of 65.8 tokens per second across 2 cited measurements. Fastest cited run: Hardware Corner.

More about this pair
How much VRAM does Qwen3 8B need?
The Q4_K_M file is 5 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 6.5 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.
What is the fastest Qwen3 8B can generate on the RTX 4070 SUPER?
Generation reads every weight once per token, so the RTX 4070 SUPER's 504 GB/s of memory bandwidth divided by the 5 GB file sets a ceiling near 100 tokens per second. Real runs land below it; SpecPicks rejects any published figure above it.

How the checks work
The fit is the Q4_K_M file size against the card's VRAM, with 1.5 GB kept for the runtime and an ~8K context. A published run counts only if the pair fits, the run is Q4-class, its source does not call it an estimate, it is under the bandwidth ceiling above, and it is not one figure pasted across many cards. The whole matrix is downloadable as a CSV under CC BY 4.0.
