Value

Unit
tok/s (decode, per-request, batch 1, KV depth 16k)
Model
Qwen3 8B Q4_K
Methodology
THIRD-PARTY LAB MEASURED (Hardware Corner per-GPU LLM benchmark page, Updated Benchmarks: March 2026). llama.cpp, single GPU, weights fully in VRAM. Context length is the KV depth the table column names. Token Generation column = batch-1 per-request decode tok/s, NOT aggregate across concurrent requests. Prompt Processing column = prefill tok/s at that context depth. Engine build hash, CUDA version and exact prompt/output token counts beyond the context-depth bucket are not published. Where the page header quotes a single '14B @ 4k' figure that disagrees with the per-model table, the per-cell table value is the one recorded.

notes
Single RTX 4070 SUPER 12GB GDDR6X, 504 GB/s as stated on the page. Same memory subsystem as the non-SUPER 4070; the two pages publish identical cells, which is recorded rather than merged because they are separate SKUs and separate pages. format_id is the nearest standard GGUF; the page labels the quant Q4_K.
