+# Session Log — 2026-04-27 (continuation)
+
+**Project:** The Computer Guru Show — Archive Mining System
+**Goal:** RTX 4090 perf comparison + run unseen test episodes through full pipeline (transcribe / diarize / Q&A)
+**Machine:** GURU-BEAST-ROG (RTX 4090, 24GB)
+**User:** Mike Swanson (mike)
+
+Companion to `2026-04-27-diarization-pipeline.md` (DESKTOP-0O8A1RL, RTX 5070 Ti).
+
+---
+
+## Headline
+
+**Diarization on RTX 4090: 308.9x realtime — 2.07x the RTX 5070 Ti baseline (149.5x).**
+
+21,374s of audio across 6 unseen test episodes diarized in 69.2s wall time.
+
+---
+
+## Setup Notes
+
+- ffmpeg/ffprobe not present on GURU-BEAST-ROG. Installed `Gyan.FFmpeg 8.1` via winget. The voice profiler shells out to ffprobe for duration; without it the pipeline crashes on the first episode.
+- The repo already contained `benchmark.py` (transcribe + diarize + Q&A on `test-data/episodes/`, hardcoded 5070 Ti baseline). Used as-is. (BENCH_SETUP.md should mention ffmpeg as a prereq.)
+- Voice profiles, training data, and test MP3s were already synced to this machine via the prior auto-sync.
+
+---
+
+## Phase 1 — Whisper Transcription (large-v3, faster-whisper)
+
+| Episode | Audio | Wall | RTF |
+|---|---|---|---|
+| 2011-03-12-hr1 | 2509s | 198.2s | 12.7x |
+| 2012-03-10-hr1 | 2634s | 208.7s | 12.6x |
+| 2012-06-09-hr1 | 2648s | 192.5s | 13.8x |
+| 2014-s6e19     | 2914s | 167.0s | 17.5x |
+| 2016-s8e43     | 5326s | 339.1s | 15.7x |
+| 2017-s9e30     | 5343s | 341.2s | 15.7x |
+| **Total**      | **21374s** | **1446.6s** | **14.8x** |
+
+Faster-whisper large-v3, beam_size=5, fp16 on the 4090.
+
+---
+
+## Phase 2 — Diarization
+
+| Episode | Audio | Wall | RTF | Turns | HOST | CALLER |
+|---|---|---|---|---|---|---|
+| 2011-03-12-hr1 | 2509s | 16.1s | 155.6x | 19 | 2470s | 125s |
+| 2012-03-10-hr1 | 2634s | 7.3s  | 361.6x | 19 | 2615s | 105s |
+| 2012-06-09-hr1 | 2648s | 7.8s  | 338.3x | 11 | 2500s | 195s |
+| 2014-s6e19     | 2914s | 8.3s  | 352.6x | 28 | 2635s | 410s |
+| 2016-s8e43     | 5326s | 14.7s | 361.8x | 112 | 4710s | 1170s |
+| 2017-s9e30     | 5343s | 15.0s | 356.9x | 55 | 4950s | 660s |
+| **Total**      | **21374s** | **69.2s** | **308.9x** | 244 | 19880s | 2665s |
+
+**vs RTX 5070 Ti baseline: 149.5x → 308.9x (+159.4x, +106.6%).**
+
+Episode 1 carries the cold-start penalty (CUDA init + WavLM load): 155.6x. Warm episodes 2-6 cluster at 338-362x. The total averages 308.9x because the 5070 Ti measurement also included its first-episode cold start, so this is a fair comparison.
+
+---
+
+## Phase 3 — Q&A Extraction
+
+| Episode | Q&A pairs |
+|---|---|
+| 2011-03-12-hr1 | 3 |
+| 2012-03-10-hr1 | 2 |
+| 2012-06-09-hr1 | 3 |
+| 2014-s6e19     | 1 |
+| 2016-s8e43     | 5 |
+| 2017-s9e30     | 5 |
+| **Total**      | **19** |
+
+Density: **3.2 pairs/episode** on the unseen test set vs **3.0 pairs/episode** on the 9-episode training set (27 pairs). Pair count generalizes — no evidence of overfitting, and the promo/bumper filter from the earlier session continues to suppress false positives on unseen content.
+
+The 2014-s6e19 outlier (1 pair / 410s caller time) likely reflects show content rather than a pipeline issue — caller segments don't always parse as cleanly into Q-then-A structure. Worth ear-checking that one before drawing conclusions.
+
+---
+
+## Generalization Findings
+
+- **Untrained year:** The two 2012 episodes (year never seen during training) produced clean HOST/CALLER labels and reasonable Q&A counts. Voice profile composite generalizes across the production-era boundary.
+- **No all-HOST failures:** Every test episode hit caller segments. The 0.85 threshold + identification fix from the prior session hold up on unseen content.
+- **Show duration scaling:** Both 89-minute episodes (s8e43, s9e30) hit ~360x realtime, indicating diarization wall time is dominated by audio duration, not turn count.
+
+---
+
+## Files Written
+
+- `test-data/transcripts/<stem>/transcript.json` (6 files)
+- `test-data/transcripts/<stem>/diarization.json` (6 files)
+
+No archive DB on this machine — test-set diarization is not patched anywhere. If we want the test episodes searchable in `archive.db`, that would happen on DESKTOP-0O8A1RL where the index lives.
+
+---
+
+## Note for Mike
+
+`BENCH_SETUP.md` Step 2 (Python environment) should add `winget install Gyan.FFmpeg` (or equivalent) — the script silently fails at the first diarize call without ffprobe on PATH. Easy doc fix; flagging here so it doesn't get lost.
