2nd Gen HBM2 Aquabolt Starts Mass Production

Samsung Aquabolt HBM2

Samsung has announced that it has started producing its second generation 8GB High Bandwidth Memory-2 (HBM2) that boasts the fastest data transmission speed on the market today.

Samsung did not mention any hardware products that will use the new technology, but it is not hard to guess that we will see high-end graphics cards with 2nd-generation HBM2 memory by the end of the year.

The new solution, Aquabolt, which is the company's 2nd-generation 8GB HBM2 DRAM to deliver a 2.4 gigabits-per-second (Gbps) data transfer speed per pin at 1.2 volt, can process 307GB of data, which is equivalent to 61 full HD 5GB movies, in one second.

The new package will offer a 307 gigabytes-per-second (GBps) data bandwidth, achieving 9.6 times faster data transmission than an eight gigabit (Gb) GDDR5 chip, which provides 32GBps of bandwidth. As for bandwidth, we're looking at around 300MBps per pin, which on a 1024-bit memory bus should provide around 307GB/sec per package, times 4 bringing us to a insane 1.2TB/sec of memory bandwidth. Samsung used new technologies within their TSV design, as well as tweaks to thermal control. By using four HBM2 packages, it is possible to achieve a 1.2TBps bandwidth, which is a 50 percent improvement compared to standard 1.6Gbps HBM2 chips.

The production milestone was heralded by Jaesoo Han, executive vice president, Memory Sales & Marketing at Samsung Electronics, who said that the new memory chips would strengthen Samsung's memory industry leadership competitiveness. An increase in the number of thermal bumps in each package and the addition of a protective layer at the bottom has further enhanced the design over its predecessor, the company claims. In the research department, Samsung says it'll continue to rapidly advance its memory technology in conjunction with leading OEMs throughout a range of fields including supercomputing, artificial intelligence, and graphics processing.
