Add batch size override to benchmark scripts. Testing -b 256 vs default
2048 on Vulkan RADV shows no meaningful difference for MoE pp2048
(826 vs 843 t/s, within noise). Community-reported +70% improvement
does not reproduce on this backend.
Replace estimated values with clpeak measurements: DRAM 216-233 GB/s,
GPU clocks confirmed 2900 MHz under load (ROCm #5750 is sysfs reporting
only). Correct backend recommendation to Vulkan RADV (2.7x faster tg
than ROCm at 131K). Update KV cache recommendation to q4_0. Add
Nemotron-Cascade-2 to coder shootout results. Remove Nemotron-3-Nano
from catalog (replaced by Cascade-2). Update Q4_K_L to Q4_K_XL entry.
Add `make optimize-power` (ryzenadj 85W, sysctl, THP, RADV nogttspill)
with systemd services for boot/resume persistence. Integrate into
`make optimize --all` as Phase 2. Update optimization log with RyzenAdj
results (+46% tg at 70W sustained), KV sweep data, and quant shootout.
Add Qwen3-Coder-30B and Nemotron-Cascade-2 to model catalog.
KV cache quantization adds type_k/type_v columns to llama-bench output,
shifting test and t/s to different indices. Parse from end of row instead
of hardcoded positions. Also fix KV suffix separator (underscore to dash)
to avoid regex ambiguity with type names like q8_0.
Add 5-phase optimization guide, optimization log for tracking results,
and research docs on llama.cpp and inference landscape optimizations.
