In recent weeks we have had occasion to report the upcoming debut of GDDR5X memories, new standard which will presumably be used both by AMD as NVIDIA in conjunction with some of its next-generation GPU.
Among the companies engaged in the production of these memories remind the American Micron, which in a press release posted on its website has reported as the first test of GDDR5 memory newly manufactured based on the manufacturing process to 20 nanometers, are very encouraging.
These first samples have reached a transfer rate of 13 Gb / s, as it should be compared with the range indicated by the technical specifications of GDDR5 standard as ratified by JEDEC: from 10 to 14 Gb / s. And 'therefore plausible to expect over the next few months a good availability of chips GDDR5X capable of touching transfer rate of up to 14 Gb / s maximum specification.
The GDDR5X standard is similar in structure to that GDDR5 but has, on paper, a data transfer rate which is twice the GDDR5 solutions. For the latter, the fastest implementation available for the moment on the market is the one to 7 Gb / s for a given double GDDR5X memories allows to reach bandwidth values of the video memory double compared to the current ones, with the same bandwidth of the memory controller.
It provides for the launch of the first next-generation video cards combined with GDDR5X memory during the second half of the year. To the top proposals for the choice should fall on the range High Bandwidth Memory Standard of second generation (HBM2), much to chose AMD as NVIDIA given the better characteristics in terms of consumption and speed performance.
