Micron Begins Shipping its First 20 nm-class GDDR5 DRAM Chips

Micron Technology announced during its Q3 FY-2015 earnings call, that it began shipping GDDR5 memory chips based on its 20 nm-class node. The company is reportedly shipping 8 Gb (1 gigabyte) GDDR5 memory chips. The company was last reported to be acquiring Japanese DRAM major Elpida, which also supplies GDDR5 chips to graphics cards, notebooks, and game console makers. The GDDR5 memory space has been saturated by companies such as Samsung and SK Hynix. The memory standard itself is on the brink of becoming obsolete; with AMD implementing HBM on its new high-end GPU, and NVIDIA expected to implement HBM with its upcoming "Pascal" GPU family. There is still quite a few GDDR5-equipped graphics cards to be sold, before HBM takes over GPUs of all market segments.

for What end ? no VGA can implement it if the gpu not support it .

8ghz and 1gb each chip... nice.

@ what power usage ?, has that been improved or the bump in speed killed the power saving from the smaller nm ?.

Exactly my thoughts. I think the market will be the consoles, smart phones?

GDDR5 is not going anywhere. It will still serve with pride on low and mid end cards for quite some time...

Besides, I don't think manufacturing process has anything to do with GPU compatibility. It's GDDR5 and that's all it matters to the memory controller on the GPU. GDDR5 itself can be 28nm, 20nm or even 14nm, I don't think GPU should care about that for as long as the interface is the same. Shrinkage just decreases power consumption, heat and cost.

Could we see a 8GB 980 Ti?
Not unless nVidia uses mixed density memory chips like on the 660. Unless you mean a 980 Ti with 8Gb chips for 12GB total, which is also a no because it would cannabilize Titan X even further.

Not sure... I guess if you want to play @ 12k then you should have 4 Titan X's not 4 980Ti's

the future I would assume is HBH so I don't really see the point of this? who is going to buy it? if NV isn't putting 8GB chips on board and AMD is using HBH now then what is the future purpose of this? HBH will be on Pascal or at least supposed to and I wouldn't see it not having it.

980Tis will never be 8gb. 6gb and 12gb, but 12gb will never happen either since that would castrate the Titan X even more.

If you keep the same capacity, yes. If you increase it/double it, is back all over again ;)

Never going to happen. :)
