New computing architecture Nvidia Volta 11/21/2017. All the latest information as of 11/21/2017.
In the first half of next year, not enough fast GDDR5 memory and more expensive GDDR5X will come to the new generation of chips - GDDR6. Samsung and SK Hynix are already engaged in the production of the latter, and mass deliveries should begin in the coming months. Nevertheless, in serial video cards GDDR6 will appear only in the spring - with the first announcements of adapters NVIDIA GeForce and / or TITAN on 12-nm chips Volta. Before, Samsung Electronics informed the public about its plans to produce GDDR6 chips with a bandwidth of 14 to 16 Gbit / s per contact (against the maximum 9 Gb / s for GDDR5 and 10-11.4 Gbps for GDDR5X), and SK Hynix announced 8 Gbps (1 GB) GDDR6 chips with a bandwidth limit of 16 Gbps per contact.
The problem of the limited bandwidth of GDDR5 graphics memory in its time led to the appearance of video cards and HPC accelerators with buffer memory HBM (HBM1) and later - HBM2. The connection of the graphic core and crystals of High Bandwidth Memory through the intermediate silicon layer allowed both to increase the bandwidth of the memory subsystem and to significantly reduce the area occupied by the key elements of the video card. At the same time, there were many shortcomings in HBM / HBM2 solutions: high production costs and, as a result, a limitation of memory capacity, a practical lack of the possibility to replace VRAM chips within a single generation of GPUs (again due to additional costs) and strong dependence on contractors. All this was the reason for the parallel release of high-end video cards with buffer memory types GDDR5,
The next generation of graphics architecture after the NVIDIA Volta will be Ampere, which is named after the physicist Andre-Marie Ampere. According to the source of this information, Nvidia is preparing the architecture for the announcement at the GPU Technology Conference in the coming year. The first real product based on Ampere will be announced later, and, in all likelihood, will be intended for supercomputers.
It's worth noting that NVIDIA has not released consumer video cards on the Volta architecture until this time, so only devices based on Pascal are available, which was presented a year and a half ago. If NVIDIA continues to use the four-digit numbering scheme, then, following the GeForce 10 Pascal family, we can expect the appearance of a series of GeForce 20 Volta and GeForce 30 Ampere. In the meantime, we can only guess. Against the background of not the most attractive price-performance ratio of AMD Radeon RX Vega adapters (especially in the first months after the announcement), GeForce 10 products are in great demand among players, and so much so that NVIDIA, for example, decided to offer the fans the TITAN Xp accelerator in a new design , not replacing the application characteristics.
The power supply voltage of GDDR6 chips is reduced from 1.5 V, like modern GDDR5 memory, to 1.35 V. The practical speed limit for GDDR5X memory is 14 Gb / s, with the mass today at 8 Gb / s per contact. Therefore, GDDR6 memory with a contact exchange at 16 Gbit / s is a solution with good prospects.
Before the release of the first professional level devices on the basis of Ampere will be held a few more technical presentations, and the output of consumer graphics cards GeForce on the newly made architecture can take even more time. Before the release of consumer graphics cards GeForce with GPU based on the architecture of Ampere, it may take a long time.
---------------------------------
so there ya have it
and don't expect GDDR6 right away since they won't be producing it right away = and you have to have enough production to meet demands
so that's late in the year
expect volta consumer with GDDR5X more likely
