SK Hynix reveals insanely fast HBM2E memory – Faster than an RTX 2080 on a single chip

SK Hynix has revealed the world’s fastest HBM memory product, promising staggering speeds of up to 460GB/s per memory stack. Each stack can also offer up to 16GB of capacity per stack, offering insane speeds and capacities given its form factor. 

For context, Nvidia’s RTX 2080 ships with 8GB of GDDR6 memory and delivers 448GB/s of memory bandwidth. Yes, that means that SK Hynix can offer two times as much memory capacity and more memory performance on a single HBM2E memory chip.   

Back in March, Samsung announced HBM2E memory stacks which offer 4.1GB/s of memory bandwidth, placing them behind SK Hynix’s latest offerings. This memory was already 2x as fast as the HBM2 memory used on AMD’s RX Vega 56, a feat which makes SK Hynix’s HBM2E offerings appear all the more impressive. 

SK Hynix targets mass production of its HBM2E memory in 2020. This is when SK Hynix believe markets for HBM2E memory will to open up. SK Hynix expects customers from the GPU market, creators of machine learning accelerators and other AI chip makers. 

Right now, the most bandwidth rich graphics card to use HBM memory is AMD’s Radeon VII, which offers 1024GB/s of total memory bandwidth. Using SK Hynix’ new HBM2E memory, a Radeon VII like graphics card would offer 1840GB/s of bandwidth, delivering a performance boost of almost 80%.
