SK hynix announces that HBM3 memory has 665 GB / s bandwidth: 44% faster HBM2e
SK hynix has teased its next-gen memory, with some early performance numbers teasing huge speeds. JEDEC has yet to formalize the HBM3 standard, which should not be too far away now.

Let’s go back to SK hynix, which has its next-gen HBM3 memory under development and is already reaching 665 Gb / s with I / O speeds of 5.2 Gb / s. This means that in its current form, HBM3 memory has 44.6% more bandwidth and 44.4% more I / O speed compared to the still fast HBM2e standard.
SK hynix explained: “SK hynix is the HBM market leader with ambitions for even faster HBM solutions: our HBM3, under development, will be able to process more than 665 GB of data per second at 5.2 Gbit / s at speed of I / O. A table illustrating the evolution of SK hynix product specifications between HBM2E and HBM3“.
If you thought 665GB / s was all that next-gen HBM3 memory was capable of, especially in a world where NVIDIA’s new GeForce RTX 30 series cards have GDDR6X that has over 1TB / s ( 1000 GB / s) of memory bandwidth – that’s not all HBM3 can do.
We’re not going to see single HBM3 stacks, where companies that use HBM3 memory in their chips will see somewhere between 2.66TB / sec of memory bandwidth, until something that could finally play Crysis with an even crazier 3.99TB / sec of memory bandwidth.
