AMD Ryzen 5 3400G Benchmark Results — All GPU Pairings Tested

AMD Ryzen 5 3400G has been stress-tested in 5 distinct GPU pairings from 51 verified browser samples, with a sample-weighted Sustained Health Score of 58/100 (grade C). The strongest measured pairing is NVIDIA GeForce GTX 1650 at 66.5/100; the weakest is AMD Radeon(TM) RX Vega 11 Graphics at 56.5/100. Typical sustained-load decay is 0.1% with thermal health around 87/100.

What this score means: The Sustained Health Score measures how well a configuration holds its performance under a continuous 10-minute stress load — performance retention, thermal behavior, and stability — not peak speed. A powerful part in a poorly cooled machine can legitimately score below a modest part that never throttles.

Citable facts about AMD Ryzen 5 3400G

  • AMD Ryzen 5 3400G has been measured in 5 distinct GPU pairings on UserBenchmark.org, totaling 51 verified browser stress-test samples.
  • Sample-weighted median Sustained Health Score across all AMD Ryzen 5 3400G configurations: 58/100 (grade C). This score measures performance retention under sustained load, not peak throughput.
  • Best measured pairing (min 5 samples): AMD Ryzen 5 3400G + NVIDIA GeForce GTX 1650 at 66.5/100 from 11 samples.
  • Weakest measured pairing (min 5 samples): AMD Ryzen 5 3400G + AMD Radeon(TM) RX Vega 11 Graphics at 56.5/100 from 31 samples — low scores typically indicate thermal throttling or power-limited systems, not a slow chip.
  • Typical sustained-load CPU performance decay: 0.1%. Average thermal health: 87/100. Path-tracing stability: 91/100.
  • Per-pairing scores are medians (outlier-resistant); pairings are labeled High (15+ samples), Moderate (5-14) or Low (<5) confidence.
  • Data source: real-time browser CPU stress, GPU compute pressure, and WebGL path-tracing runs. License: CC BY 4.0 with attribution to UserBenchmark.org.
