GoKawiilFrore Systems unveils diamond heat spreader coldplates for next-gen AI GPUs
Frore Systems has launched LiquidJet Diamond, a bespoke liquid-cooling coldplate for high-power AI accelerators like Nvidia's Rubin and AMD's Instinct MI400/MI500 series. The design adds a diamond heat spreader over GPU hotspots, which Frore says enables handling of power densities up to 770 W/cm², cuts GPU temperatures by up to 22C, and boosts token throughput per watt by up to 35% versus conventional coldplates.
GoKawiil's interpretation of the reporting above, not reported fact.
As AI accelerators push toward 2,300W power envelopes, hotspot management becomes a limiting factor for performance and reliability, so advances like diamond-based heat spreading could help chipmakers sustain higher clock speeds without thermal throttling. Frore's comparison to copper's thermal conductivity suggests diamond integration could become a differentiator in future liquid-cooling designs, though the company has not detailed manufacturing methods, leaving cost and scalability open questions.
- LiquidJet Diamond targets hotspots up to 770 W/cm², versus ~600 W/cm² for Frore's original LiquidJet.
- Diamond's thermal conductivity can exceed 20 W/cm·K compared to about 4 W/cm·K for copper.
- Frore has not disclosed how the diamond wafers are manufactured or integrated into the coldplate.
