Benchmarks

All runs below were captured on our own AMD BC-250 with SkillFishOS at 1080p, with the 40 Compute Units unlocked. Real screenshots, full settings, and the clocks/temperatures/power recorded during each run.

Unigine Heaven 4.0	1080p Ultra, 8x AA, Extreme tess.	113.7 FPS · score 2865

Black Myth: Wukong — 112 FPS

GPU ~1.4-1.6 GHz (not saturated — CPU-bound), edge 83-86 C, ~90-140 W; CPU ~3.5 GHz, 85 C; VRAM up to ~4.4 GB; fan ~3000 RPM.

Unigine Superposition — 1080p High: 12938

OpenGL · 1920x1080 fullscreen · Shaders High · Textures High · DOF + Motion Blur on · CPU @ 3894 MHz.

Unigine Superposition — 1080p Extreme: 5513

Same as above but Shaders Extreme. FPS avg 41.25 (min ~32.8, max ~49).

Unigine Heaven 4.0 — 113.7 FPS / score 2865

OpenGL · 1920x1080 · 8x AA · Ultra · Extreme tessellation · min 54.8 / max 219.5 FPS.

Synthetic compute

vkpeak (Vulkan) on the same board, before and after the 40-CU unlock:

Metric	Baseline 24 CU	SkillFishOS 40 CU
FP32 scalar	6141 GFLOPS	11 329 GFLOPS (~11.3 TFLOPS)
FP16 vec4	12 260	22 685
int8 dot-product	24 550 GIOPS	45 495 GIOPS

Memory bandwidth (clpeak): ~350-367 GB/s. Vulkan sees ~13 GiB with the extended GTT.

Comparisons

• Same hardware, +34% just by changing the OS — Superposition 1080p Extreme: SkillFishOS 5513 vs another distro at stock clocks 4102.
• Versus desktop Radeons — gaming performance in RX 6600 / 6600 XT territory, raw compute of an RX 6700 (~11.3 TFLOPS), from a ~50 EUR board.
