Why is this important? Because slapping chips on top of a glass substrates rather than organic ones for chiplet-to-chiplet and chip-to-motherboard communication has all kinds of benefits. We reported in September thatIntel is already planning on using glass substrateswhich has benefits such as “allowing for more chiplets in a smaller footprint, higher interconnect density, faster IO, higher power efficiency, and larger package sizes.”
In essence, glass substrates are flatter, more durable, and allow for easier lithographic insertion of more (and more densely packed) interconnects. In AMD’s case, chiplet-to-chiplet and chip-to-motherboard interconnects form part of its now-staple Infinity Architecture. So, if AMD hasn’t patented “Infinity Glass,” it should probably do so now.
According toTrendForce(viaWccftech), AMD is already “conducting performance evaluation tests on glass substrate samples from several major global semiconductor substrate companies, intending to introduce this advanced substrate technology into semiconductor manufacturing.” But while AMD might be evaluating samples, this doesn’t mean all the semiconductor substrate companies are near to mass production.

Whenever glass substrates do end up coming to market, we can be pretty confident they won’t initially feature in thebest gaming CPUs—or any other regular desktop chips, for that matter. This is because glass substrates for now only seem to be really beneficial for big, multi-chip packages.
While AMD’s all for chiplet designs in its gaming processors, it will probably make more sense to deliver the newest fabrication technologies over to AI and HPC datacentres. In AMD’s case, this will be its EPYC lineup which features more than just the couple of interconnected CCDs (chiplets) that you’re liable to find in a desktopZen CPU. The next generation of EPYC processors, however, is set to use regular organic substrates, so there will be a slim window for the 2025 or 2026 prediction to become accurate.

Whatever the case, it’s good news that AMD, as the king of modular processor designs, seems to be moving quickly towards this new fabrication technology which will hopefully filter down into our gaming processors before too long.
