Diamond Foundry, a company that produces diamonds, is making strides in using diamonds to cool the best CPUs and GPUs. Their testing on a high-end Nvidia GPU with synthetic diamond wafers has shown three times the performance of standard manufacturing materials, according to the Wall Street Journal.
While these benchmarks have not been made public, if true, this could make the graphics card the fastest in the world. This development highlights the increasing need to keep microchips cool as components become smaller and more powerful.
Diamond Foundry’s project, which began 30 years ago, has resulted in the creation of the world’s first 100mm single-crystal diamond wafer using a technology called heteroepitaxy. This has the potential to scale in the future.
In contrast, Intel has been focusing on using glass substrates in its product line to improve communication between different chips, rather than directly cooling the components. Diamond Foundry is aiming to reduce defect density in its diamond waver and maximize diamond’s potential as a cooling mechanism, claiming it is significantly better than silicon and silicon carbide in terms of cooling efficiency.
