Hardware Corner RTX 5070 Ti local LLM benchmark page

Per-card GPU LLM benchmark page, header reads 'Updated Benchmarks: March 2026'. Same lab method as the RTX 5090 page already ingested: llama.cpp llama-bench, Ubuntu 24.04, CUDA 12.8, Q4_K GGUF (gpt-oss 20B labeled MXFP4), per-request batch 1. Headline: 58.0 t/s generation and 2,304 t/s prompt processing on 14B 4-bit at 16k context, matching the 14B 16k cells. Tables transcribed for Qwen3 8B, Qwen3 14B and gpt-oss 20B at 4k through 128k. 16 GB GDDR7, 896 GB/s, 300 W. Not a vendor measurement. Distinct from hardware-corner-gpu-ranking-local-llm, which prints a different 16k Qwen3 8B decode for this card (127.72 vs 87.5 here).
