    Secret Buyer gibt 300-Millionen-Dollar-Bestellung für AMD-GPUs auf, die mit im Labor gezüchteten Diamanten gekühlt werden


    Diamanten können offenbar den Stromverbrauch von Rechenzentren senken

      This is an AI efficiency play I hadn’t heard of yet. They aren’t gemstone shaped but more like sheets of diamonds inside the chip, produced at lower price points than what goes in jewelry.

      Makes sense considering diamond has a much higher thermal conductivity than IIRC almost any other material you could make a heat sink out of. Lab grown diamonds aren’t even that expensive. I am really curious about the math on this though, seems counterintuitive for sure

      Assuming this pans out, short term it might increase price of lab-grown diamonds, but long term it will almost certainly make lab-grown diamonds even cheaper. The jewelry industry is in a world of hurt (Yes, these guys aren’t buy lab-grown jewelry grade diamonds, but the process for making them is certainly similar enough that increasing production in one results in a reduction in the other).

      So lab-grown diamond rings are cheaper than mined, but still probably wildly overpriced.

      Cu-diamond and CVD heat spreaders are not new….you can even find them on aliexpress.

      Hey cool! I make that stuff. Didn’t know it had been picked up to that extent.

      This is nothing new. I visited a US research lab (part of DARPA, i think) over 30 years ago that was working on this technology. Not only is diamond an excellent thermal conductor, it’s also an electrical insulator. Hence they were also experimenting with using lasers to convert areas of diamond back into graphite, allowing them to ‚draw‘ conductive tracks onto the diamond surface to create interconnections.
