As graphics and other workloads move more and more to using large amounts of data, the need for faster memory and more efficient will grow. This is why new memory technologies have been and continue to be developed, such as High Bandwidth Memory, HBM, with HBM2 being used in some devices today. Samsung is among the companies developing and producing HBM2 and announced today it is starting mass production of its second generation HBM2, called Aquabolt.
Samsung's first generation HBM2 is called Flarebolt and is able to achieve 1.6 Gbps per pin at 1.2 V and 2.0 Gbps at 1.35 V. Aquabolt surpasses both values, reaching 2.4 Gbps pin speed at 1.2 V, which translates to 307 GB/s bandwidth for a single 8 Gb package on a 1024-bit bus. For comparison, an 8 Gb GDDR5 chip can provide 32 GB/s bandwidth, using a 32-bit bus.
