Lab-Grown Diamonds: The Secret to Cooler GPUs

AI is advancing, and so are today's data centers. With the advancement in AI, tech companies are running towards building more data centers that will work on the latest AI models. This has led to an increased consumption of electricity. At the heart of these systems lie Graphics Processing Units (GPUs). Known as a specialized form of CPU, they operate based on parallel processing and feature multiple cores. These characteristics make them highly suitable for the operation of AI models and computational tasks.

The problem lies here - most of the electricity used by a computer chip is not used for computing. Instead, most of it gets wasted as heat. This excess heat affects the lifespan of the chip and shortens its life. As the computational work is increasing the load on GPUs is also increasing , resulting in heat generation at the chip level. To eliminate the excessive heat, data centers are spending significant money, yet this issue keeps increasing and requires urgent attention. Lab-grown diamonds bring in much needed advantages here. Diamond-based device fabrication can provide an efficient cooling solution as it has the highest thermal conductivity and mechanical strength. 

Known as the hardest material, they can move heat smoothly from one place to another. Today, engineers have been embedding thin layers of lab-grown diamonds on silicon chips to ensure cooling and make the chips last longer. 

Shortcomings Associated With Datacenters Using Silicon 

Tech companies have long relied on conventional materials for datacenter GPUs. 

Silicon has long served as the base for computing for decades. But with the growing demand for AI-driven computation, high-performance graphics, and data-intensive workloads, silicon is soon beginning to show serious limitations in thermal management, efficiency and scalability. 

Commonly used materials for datacenter GPUs such as silicon and silicon carbide tend to face limitations: 

• Thermal Limitations: The low thermal conductivity of silicon creates hindrance in effective dissipation of heat. The low thermal conductivity of silicon (at 150 W/mK) makes it incapable of handling heat flux that is frequently generated by today's modern high density components. This limitation results in increased reliance on complex and energy-intensive cooling solutions. In extreme cases, insufficient thermal management can cause device failures, data loss, or require throttling of processing speeds. 

• High Power Density: GPUs made from silicon based material are subjected to be operated at high-frequency and high power density, resulting in excessive heat generation, system failures and hardware degradation. The weak thermal management of silicon chips restricts data centers ability to achieve peak performance. 

• Electrical Breakdown: The low electrical breakdown field of silicon (0.3 MV/cm) limits how much voltage it can handle. Today chip designers aim for higher voltages and power densities where the use of silicon will not be useful as it will be prone to leakage currents and dielectric breakdown. 

• Cooling Infrastructure Limitations: When powerful silicon hardware is packed tightly into server racks, it creates a huge amount of heat which at times also exceeds 120 kW per rack. This level of heat cannot be managed through traditional air cooling. That is why it is essential to find efficient ways to manage heat. Materials like diamonds are proving to be valuable when it comes to spreading heat away from the chips.

How Diamond Based Solutions Address These Issues? 

Lab-grown diamonds are proving to be a sustainable and green solution to the ever growing issue of heat. Today engineers have started embedding diamond wafer technology into computer chips to deal with the excessive heat generation. There are companies that have started manufacturing diamond layers for the purpose of chip cooling. As more and more companies are moving towards greener technology, lab-grown diamond wafer technology is set to expand. 

• Outstanding Thermal Conductivity 

  Single crystal diamonds with high purity exhibit thermal conductivity in the range of 2000 W/mK. Lab-grown diamonds when combined into a cooling structure significantly lowers thermal resistance. It is said that cooling structures with diamonds can lower thermal resistance compared to traditional materials like silicon, silicon carbide, copper or aluminum. The result of this is better device performance even under extreme conditions. 

• Extends Lifespan 

  The ability to drive away heat is a key property of diamond-based solutions. This helps maintain optimal operating temperature for electronic components. Further, the risk of overheating is reduced which eventually extends the lifespan of chips. 

• Reduces Cooling Cost 

  If the heat is dissipated in the right way, it results in effective heat management and reduces the need for bulky cooling systems. This leads to low energy consumption and eventually results in reduced cooling costs. 

• Directly Attached to Chips 

  The best part about lab-grown diamonds is that they can be directly attached to chips. By embedding diamond-based materials onto chips, companies can enhance the heat management of electronic devices without major design changes. This seamless and effortless integration of diamonds makes it easy for companies to use diamond-based solutions without incurring additional costs.
