+## Which GPU, on a machine with more than one
+
+**Measured 2026-08-29** on a laptop holding an Intel Iris Xe (RPL-P) and an AMD
+RX 5700 XT, same binary, adapter forced with `VK_ICD_FILENAMES`.
+
+The question was whether an integrated GPU is the better choice for this
+application. The argument for it is good: a 24 MP frame is ~96 MB of RGBA, and
+on a discrete card every upload and every export readback crosses PCIe, where
+an iGPU shares memory with the CPU and crosses nothing. It also does not empty
+a battery.
+
+The compute says otherwise, and not marginally.
+
+| 2560×1600, p99 | AMD RX 5700 XT | Intel Iris Xe |
+|---|---|---|
+| fused pass, `point` | 5.19 ms | 7.75 ms |
+| fused pass, `all` | 11.70 ms | **66.42 ms** |
+| M3 clarity, fit | 4.67 ms | **38.28 ms** |
+| M3 all four, 1:1 | 6.44 ms | **57.67 ms** |
+
+| 1920×1200, M3 clarity, fit | 2.35 ms | **19.99 ms** |
+|---|---|---|
+
+The fused colour pass is within a factor of 1.5 — it is one read and one write
+per pixel, which an iGPU does perfectly well. The **neighbourhood stage is
+5–8× slower**, and that is what decides it: clarity at 1920×1200 costs 20 ms on
+the Iris Xe, so it leaves the budget on its own at the smallest size tested,
+before anything else in the chain runs.
+
+**So the default adapter preference stays `Performance`** (`dr_gpu::AdapterPreference`).
+
+Two things this does *not* show, and neither is a reason to revisit the default
+without measuring them:
+
+- **It does not refute the transfer argument.** This harness renders from a
+  resident texture and never uploads or reads back, so the PCIe cost an iGPU
+  avoids does not appear in any column above. Import, export and the thumbnail
+  sweeps are transfer-heavy and compute-trivial, and may well go the other way
+  — but they are not what FR-DSP-3 bounds, and one device is opened at startup
+  and shared with the compositor, so there is currently no way to use a
+  different adapter for a different task.
+- **It says nothing about power.** `Efficiency` remains offered
+  (`DARKROOM_GPU=integrated`) because a user on battery may rationally accept a
+  slower detail chain, and because someone whose discrete card has failed needs
+  a way to keep working.
+
