Samsung 2nd-generation HBM2 memory chip

While I am a bit unsure of the "Aquabolt" name, there is no doubt that HBM is finding its place in the industry, and now HBM2 is in production by Samsung. The package, dubbed Aquabolt, delivers data transfer speeds of 2.4 gigabits-per-second (Gbps) per pin which Samsung says translates into a performance boost of almost 50 percent compared to its first-gen offering.

When it comes to performance, Samsung Electronics' second generation HBM2 memory controller features a "pin speed" of 2.4Gbps at 1.2V.

To measure price-variation, we found GSK's volatility during a week at 1.31% and during a month it has been found around 0.94%. GlaxoSmithKline plc ( GSK ) exchanged hands at an unexpectedly high level of 5.91 million shares over the course of the day.

According to Samsung, the 8GB HBM2 package peaks at 307.2 GB/s of bandwidth, which is 9.6 times faster than on an 8Gb GDDR5 chip. The improvement equates to a overall transfer rate of 307GBps.

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. 'We will continue to reinforce our command of the DRAM market by assuring a stable supply of HBM2 worldwide, in accordance with the timing of anticipated next-generation system launches by our customers. For the greater speeds achieved Samsung had to tweak the TSV design while minimising inter-layer skew. Samsung Electronics further mentioned that that the introduction of a faster HBM2 module "should accelerate the expansion of supercomputing and the graphics card market". The new chip design includes an increased number of thermal bums for stronger thermal control, as well as an additional protective layer at the bottom that provides an increased physical strength for the entire package. The South Korean tech giant hopes to triple its share in the HBM2 market thanks to ramped up production and its new generation product.
