SK Hynix teases HBM3 with 12-Hi 24GB stack layout, 6400Mbps speeds

The world of consumer graphics cards has moved from HBM to GDDR6 quite quickly, with the flagship NVIDIA GeForce RTX 30 series GPUs rocking the ultra-fast Micron GDDR6X memory. But the world of HBM hasn’t stopped, and now SK Hynix is ​​showing off its 24GB HBM3 memory clocked at 6.4Gbps.

At the recent OCP 2021 summit, ServeTheHome spotted part of this delightful new HBM3 memory from SK Hynix and took a photo of it. It was pretty quick for SK Hynix to flaunt it since the company only announced its new HBM3 memory less than a month ago now – and it’s also as thin as a piece of paper. A4.

We don’t have the final specification for HBM3 from JEDEC yet, but SK Hynix has already upgraded the original specification from 5.2 Gbps to 6.4 Gbps – and that’s a good thing. We should see next-gen accelerators and other products powered by HBM3, with absolutely brutally fast memory bandwidth. Damn, the 12-Hi stack on a 1024-bit memory interface can drive 819.2 Gb / s per stack … with multiple stacks we’re looking at numbers of memory bandwidth never seen before.

The new SK Hynix HBM3 memory could be found on a product with 12 x 12Hi HBM3 batteries, which would release 288GB of HBM3 on a single GPU, with a what-in-the-fresh-hell-black-magik-is-this 9.8 TB / sec (yes, 9800 GB / sec) of memory bandwidth. Madness, and I want it now. Even though I can’t use it, man 9.8TB / sec of memory bandwidth is so awesome.

Imagine crypto mining on this thing.
