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.
Atomically perfect diamonds are 10x as conductive as diamonds but can only be produced in tiny sheets. I wonder what the real benefits are here

I know they were looking at making a type of graphene lattice aerogel. If you could make one of those structures that is like 98% empty spaces within carbon tubes conducting heat into the air it would work amazing as a heat sync, unfortunately current aerogel would be more insulating than conductive for heat transfer.

You know what conducts heat even better than diamonds? A fast moving liquid.

That’s only surprising if you still haven’t noticed the existence of [diamond thermal paste (2011 !)](https://www.igorslab.de/en/oldies-but-goldies-innovation-cooling-ic-diamont-24-in-the-testand-far-ahead-of-its-time/) (nor heard about how artificial diamond prices crashed).

This project reads like an investment scam.
