Max Thermal Spread by Configuration
Lit Silicon Threshold Violations
// KEY_INSIGHTS
Cooling Infrastructure Impact
The 8-GPU Quebec test (13°C spread) performed BETTER than the 4-GPU California test (25°C spread) because Quebec datacenter had superior cooling with starting temps of 5-11°C vs California's 40-47°C.
Straggler Identification
In the 4-GPU test, GPU3 was identified as the thermal straggler 65.4% of the time, consistently holding back the entire training job due to C3 coupling effects described in Lit Silicon.
Critical Threshold Exceeded
The 25°C max spread is 167% above the Lit Silicon critical threshold of 15°C, indicating severe performance degradation potential in production multi-GPU training workloads.
Total Data Collected
Thermal samples across multiple configurations, validating the Lit Silicon phenomenon on NVIDIA consumer and prosumer GPU hardware.
