Akash Systems has unveiled a cutting-edge diamond-cooling technology for GPUs, marking a transformative moment in thermal management for electronics. Supported by $18.2 million in CHIPS Act funding and an additional $50 million in federal and state tax incentives, this innovation promises to improve efficiency across data centers and even space satellites.
The Science Behind Diamond Cooling
Diamonds, boasting thermal conductivity five times greater than copper, make ideal cooling substrates. Akash Systems incorporates synthetic diamond substrates in its GPUs, leveraging their properties to:
- Dissipate heat more effectively.
- Operate at higher power levels with lower temperatures.
- Ensure both thermal and electrical stability, as diamonds do not conduct electricity.
The result? Enhanced thermal efficiency, enabling chips to perform at their full potential without the risk of overheating.
Real-World Impacts: GPUs and Satellites
Akash’s diamond-cooled GPUs deliver remarkable performance improvements:
- 10–20°C reduction in hotspot temperatures.
- 50% lower fan speeds, reducing noise and power usage.
- 25% boost in overclocking capabilities.
- Doubled server lifespan, saving data centers millions in cooling costs.
For satellites, Akash applies GaN-on-diamond technology to power amplifiers, drastically improving heat dissipation. This innovation supports:
- Increased communication bandwidth.
- Reduced system size, weight, and operational costs.
- Enhanced reliability in harsh space environments.
Building a Sustainable Future
Akash’s process involves integrating diamond cooling with existing GPUs from leading chipmakers like NVIDIA and Qualcomm. Long-term goals include manufacturing its own diamond wafers, further advancing sustainability in electronics.
GaN-on-Diamond: A Proven Track Record
Akash co-founder Dr. Felix Ejeckam, who pioneered GaN-on-diamond technology in 2003, leads the charge. His previous venture, Group4 Labs, was acquired by Element Six Technologies, a subsidiary of De Beers, underscoring the revolutionary potential of diamond-based cooling.
Diamond cooling is set to redefine the electronics landscape, offering groundbreaking performance benefits and setting new standards for energy efficiency.
