SK Hynix has just unveiled specifications of its next-generation HBM3 memory which will deliver higher transfer rates, increased capacity, and new thermal improvements.

On its product page, SK Hynix has now listed down a comparison chart comparing its current-gen HBM2E memory to the next-generation HBM3 memory. As per the DRAM manufacturer, the HBM3 memory is expected to achieve 5.2 Gbps I/O speeds which is a 44% improvement over the existing HBM2E memory. This would lead to increased memory bandwidth too and SK Hynix has provided figures on that front too.
