Hybrid Memory Cube is Nearing Production
The new volumetric memory technology that aims to replace DRAM as the main memory in computers has appeared in "metal". Promises of HMC. Able to deliver 320 GB/s of bandwidth sounded too good to be true, but Micron is showing their work. They have shipped the first 2 GB engineering samples capable of 160 GB/s bandwidth. They plan to release the 4 GB samples at the beginning of 2014 and start volume production later the same year. Micron expects that HMC should appear en-masse in consumer devices in 3-4 years. It will be interesting to see if this really catches on at an affordable price, as the most powerful modern iGPUs are limited by DDR3 bandwidth. Having much faster and responsive main memory should be very beneficial for such cases.
