Memory Systems: HBM and the Bandwidth Wall

201Mach Eigen28 min readNarratedFree during beta

The accelerator isn't limited by math. It's limited by how fast memory can feed it. This course follows that constraint from the physics inside a high-bandwidth memory stack, to the small group of suppliers who make it, to what it does to the price of a token. You know the basics. This is where the mechanics come in. Glad you're here. — Myke Founder, Faraday Intelligence
