Think the future of the graphics cards is only in the memories of the HBM2? You should consider this again,GDDR5 Signaling that he was planning a surprising comeback
After several years of getting used to seeing GDDR3 memories and then GDDR5 memories, in our graphics processing products, without too many surprises - the last two years have marked the beginning of a different trend, where there is a race between different technologies and more significant importance than the type of video card used. HBM (High Bandwidth Memory) made its debut on the cardsRadeon Fury, and indicated that GDDR is no longer the most advanced default.
While SK Hynix and Samsung began accelerated development of products based on HBM, alongside GDDR5, the third major player in the memory market, Micron (which develops a standard Memories Stacked from a competitor called the Hybrid Memory Cube), chose to continue developing and improving the old and common standard - and introduced to the world the GDDR5X, which successfully provided increased bandwidths that approached those of the new generation standard, but maintained the relative simplicity and convenience of implementing the various products.
It started with an effective operating frequency of 10GHz (or 10,000MT / s) on the GeForce GTX 1080, which provided a decent actual bandwidth of 320GB per second - and was later upgraded to an operating frequency of 11,000MT / s and bandwidths of over 450 GB per second GTX 1080 Ti, and even bandwidth of almost 550 GB per second on Titan XP The formidable, thanks to the 384-bit enlarged working interface. Now, Micron declares that they also aspire to reach a crazy effective working frequency of 16,000MT / s in the GDDR5X era - even before we get to see the arrival of the standardGDDR6 Future.
The American company declares that they have succeeded in operating Memories Modern GDDR5X created in 20 nm lithography at the insane speed of 16,000MT / s, which is about 40 percent higher than the maximum speed we have seen to date in standard-based commercial chips. This happened under laboratory conditions, naturally, but the company is convinced that this will be possible to apply in real products in mass production in the near future - and if it does, it will mean even more impressive bandwidths of up to 512 GB per second based on On 256-bit interfaces (like the one in GTX 1080) and up to 768 gigabytes per second based on more advanced 384-bit interfaces.
It should be noted that the HBM and HBM2 products launched so far in the gaming world have offered practical bandwidths between 480 and GB to 512 gigabytes, while the new Tesla V100 NVIDIA Which uses cutting-edge memories in the market, has a bandwidth of about 960 gigabytes per second.
Such upgraded GDDR5X memories may reach actual products on the market during 2018 - in parallel with the first GDDR6 memories, which will be based on a reduced production process by 16 nm and are designed to offer an effective speed of 12,000MT / s as a base, with potential for speeds of 16,000MT / s and even beyond that with the maturation of the capabilities, in the power consumption that will probably be smaller than we are used to seeing inGDDR5 And in the GDDR5X, so there is much more to look forward to,HBM2 And making it more popular and accessible, of course.
For the sake of dessert, Micron has also announced intentions to switch to the production of old and good GDDR5 memories in an up-to-date and efficient 16 nanometer lithography, with continued planned use in the foreseeable future both in the market for the medium and low-end gaming consoles, which finally disconnects the DDR3 Haiti is absolute. We've already received fromNVIDIA Launch of cards GeForce GTX 1060 with a new and improved generation of chips GDDR5 Which operates at a nice effective frequency of 9,000MT / s, and it can be assumed that a jump from a current production process of 20 nm to the 16 nm process could allow the continued pushing of capabilities forward, to a level of 10,000MT / s and maybe even 11,000MT / s. In other words - it is possible that what is currently sold to us from the leading video cards in the market will also become available for popular and discounted models within a year or so.
So with all due respect to HBM which is developing rapidly, offers impressive efficiency and is even expected to have a third and even more advanced generation in about two years - it seems that the GDDR standard does not give up so quickly, and is ready to be the most sane and affordable alternative for gamers, reality lovers Simulated and stratified, digital currency miners and computational learning developers.
