Video summary

40CU AMD BC-250 VS RX6700 and RX7600 in Black Myth: Wukong. Results have surprised me!

Main summary

Key takeaways

Gaming

Game storyline

  • None discussed. The subtitles focus entirely on GPU benchmarking/performance rather than narrative or in-game story.

Gameplay highlights / what the video is actually about (Black Myth: Wukong performance testing)

  • The video compares performance in Black Myth: Wukong using a benchmark tool.
  • The key variable being tested is unlocking additional GPU compute units on the BC-250:
    • Starts from 24 compute units
    • Moves to 40 compute units (unlocked), described as a major performance bump.

Key performance findings (benchmark conclusions)

  • With 40 compute units unlocked, the BC-250’s GPU performance is reported to match closely the performance levels of:
    • Radeon RX 6700
    • Radeon RX 7600
  • Noted limitations:
    • The GPU does not have int8 instructions, so FSR 4 is not available/usable.
    • The architecture is described as a PS5-like mix (not fully RDNA 2/3), which affects how certain features may work.

Strategies / key tips mentioned

Benchmark approach (method)

  • Use the Black Myth: Wukong benchmark tool.
  • Compare results against:
    • The creator’s own runs with standard presets
    • YouTube benchmark results from other channels for RX 6700 and RX 7600 (since the creator doesn’t own both cards)
  • Replicate the same settings across sources to keep comparisons meaningful.

Feature expectations

  • Don’t expect FSR 4, due to missing int8 instructions.

Hardware context used for performance expectations

  • The BC-250 GPU is described as “basically the same as PlayStation 5”, with compute units increased:
    • PS5: 36 compute units
    • BC-250: 24 → up to 40 compute units unlocked
  • Reference GPUs used for comparison:
    • RX 6700 is treated as the closest Radeon match to PS5-like specs (also 36 compute units).
    • RX 7600 is used as well, because the creator observes it performing similarly to RX 6700 in relative charts.
  • Rough estimate for a “Steam machine” mentioned:
    • Steam machine RDNA3 estimate: 28 compute units
    • The creator claims RX 7600 desktop power is ~20% higher, estimating BC-250 could be ~20% more powerful GPU-wise (with a caveat about CPU limitations: “six cores with small cache”).
