[Guru3D] Samsung to offer GDDR6 at 14 - 16Gbps Bandwidth in 2018

SOURCE: http://www.guru3d.com/news-story/samsung-to-offer-gddr6-at-4-16gbps-bandwidth-launches-2018.html
Quote:
GDDR6 when released will start right where GDDR5X will end, at roughly 14 Gbps. The technology is expected to have been advance to 16 Gbps by the year 2020. This means more bandwidth (double over current bandwidth) and higher clock frequency memory. Volatges wise GDDR6 will be rated at 1.35v, which is exactly the same as GDDR5x.

This new information was posted by computerbase who derived the info and slides below at the Hot Chips 28 event. Samsung is also hard at work on ddr5 and laptop lpddr5 memory, also expecting a release in 2018.





I guess GDDR isn't dead afterall? Hopefully this new GDDR6 will retain the low manufacturing costs of GDDR5X and not swing towards the much more expensive HBM2.

There's HBM3 that offers 64GB and 2.0TB/sec

Icelake-X and hex channel DDR5 6000+?

So HBM will never really become mainstream? GTX1080 10Gbps G5X, 1180 12-14Gbps G5X, 1280 14-16Gbps G6.

With this, HBM will probably be more niche to the super high end. The amount of influence that Samsung has will assure GDDR6 will live to see the light. Especially with lower production costs than HBM (I'm sure of it), it'll be the go to. Besides, where and when can we see the true benefits of super fast speeds of HBM?

If you take 290X with 512-Bit and put G6 you have 3x the memory bandwidth.

But is there a way to measure how much of the bandwidth is actually getting saturated? Versus just knowing that you have "this much" bandwidth available.

id say with those speeds no, because at that point your bottleneck isnt memory.
heck, even at current gen speeds the bottleneck isnt memory.

GDDR5 so old now it's like bad popular back in 2008 with 4870 back then nvidia still had gddr3 lol. Can't believe we haven't moved out of that era. Also nice how AMD let's nvidia use their technology from those twin frozer heatsink to the blower design.
