Frore Systems Claims LiquidJet Can Reduce Nvidia Rubin GPU Temperatures by 10°C
Key points
- Frore Systems' LiquidJet technology can reduce Rubin GPU temperatures by 10-12°C.
- A 10°C temperature drop could boost token generation by 15%.
- Improved cooling directly translates to higher sustained performance for AI hardware.
- Modern AI accelerators like Nvidia Rubin can dissipate up to 2,400 W.
Cooling for AI Accelerators
Frore Systems, a manufacturer of cooling solutions, has presented findings on reducing temperatures in next-generation AI accelerators. The company's white paper suggests that improvements across the entire cooling stack, including GPU packaging, thermal interface materials (TIMs), coldplates, and coolant temperatures, can increase token generation per watt by over 30%.
LiquidJet Technology's Impact
Based on an analytical thermal model, Frore Systems projects its LiquidJet coldplate technology can lower Nvidia Rubin GPU junction temperatures by up to 12°C. This temperature reduction is estimated to translate into a 10% to 25% improvement in tokens per Watt, with a 10°C reduction specifically linked to a 15% increase in token generation.
The Challenge of High Temperatures
Modern AI accelerators, such as the upcoming Nvidia Rubin, can dissipate up to 2,400 W, leading to die temperatures that can exceed 95°C. While 95°C may not immediately impact silicon longevity, high temperatures significantly increase leakage current, which doubles approximately every 10°C. This also reduces transistor switching efficiency.
Performance Implications
Elevated temperatures necessitate higher voltages to maintain clock speeds, which often triggers Dynamic Voltage and Frequency Scaling (DVFS) to reduce clocks to stay within thermal limits. This ultimately leads to decreased performance and lower token output. Therefore, better cooling directly correlates with higher performance and token generation in AI data centers.
