+## RTX 4090 offloaded comparison
+
+Measured on one RTX 4090 (24 GB), `864x480`, 56 frames at 24 fps, 20 steps,
+CFG 1, seed `42`, every component offloaded to CPU (`--offload-to-cpu`),
+`--max-vram 22`, model-specific `16x16` VAE tiling. On a single 24 GB card
+neither the BF16 DiT nor the Qwen3-VL encoder fits resident, so both engines
+stream weights per segment. Q8_0 rows quantize the BF16 files on load
+(`--type q8_0`). Wall is the end-to-end process time (measured identically for
+both engines); TE / Diffusion / VAE are per-stage times. "Load" is not shown as
+a column because the engines load differently — edge-dit loads all components up
+front, sd.cpp loads each lazily on first use — so a single load figure would not
+be comparable. Peak VRAM is sampled over the whole process. Bold marks the
+better value in each edge-dit vs stable-diffusion.cpp pair.

+At q4_K_M the two engines match on diffusion time; edge-dit encodes text
+**3–8x faster**, decodes the VAE **~2.5x faster**, and holds peak VRAM roughly
+**2 GB lower**. At q8_0 edge-dit leads across the board — **~25–30s lower wall
+time**, diffusion **~40% faster**, peak VRAM **~3.5 GB lower**.
+
+sd.cpp has no BF16 rows on this card: it stages the full-precision DiT weights
+to the GPU in one block (~38 GB), which overflows the 24 GB budget and aborts
+before sampling. edge-dit streams the BF16 weights per segment, so it runs
+within the 24 GB limit.
