Samsung GDDR6 memory announcement spotted - going for 16 Gbps
In a press release regarding CES awards, Samsung dropped a snippet of info on an award they received for GDDR6 graphics memory. The info actually tells a thing or two about the specs and technology.
So this is what the press-snippet states:
Samsung 16Gb GDDR6 Memory – The fastest and lowest-power DRAM for next generation, graphics-intensive applications. It processes images and video at 16Gbps with 64GB/s data I/O bandwidth, which is equivalent to transferring approximately 12 full-HD DVDs (5GB equivalent) per second. The new DRAM can operate at 1.35 volts, offering further advantages over today’s graphics memory that uses 1.5V at only 8Gbps.
And that means double the bandwidth over current gen 8Gbps memory as used on say a GeForce GTX 1070 Ti. it's good news as we know it's coming likely on the next wave of graphics cards, also it uses less voltage and can theoretically double the bandwidth over current gen GDDR5 memory. To compare a little, current GDDR5 memory on say a Radeon RX 480 / GeForce GTX 1070 is roughly 7 or 8 Gbps, and GDDR5X on a GTX 1080 can do 10 or 11 Gbps.
Well, GDDR6, when released, will start right where GDDR5X will end, at roughly 14 to maximum 16 Gbps. his means more bandwidth (up-to double over current bandwidth) and higher clock frequency memory. Voltages wise GDDR6 will be rated at 1.35v, which is exactly the same as GDDR5x. Other companies like SK Hynix and Micron are on track with GDDR6 as well.

I remember reading some months back here on guru3d that shortage on supply will cause a huge price spike later on.
Love it but I've noticed that DDR 4 memory has gone up drastically in price recently, I wonder what's up with that?

Seems so slow compared to HBM2, but still a major improvement. Might be worth using for mid-range hardware, whereas HBM is best used in high-end and GDDR5 for everything else.
My 16GB kit was around $70 when new, and last time I checked it was over $140.

Yeah no the effective bandwidth of the 1080ti is higher than the vega64 with 11Gb/s chips. 16Gb/s would boost that cards bandwidth by about 46%.

Memory seems to be being made at insane rates right now (least the technology of it) we was stuck on GDDR5 for ages same with DDR3, now they announce ddr5 should be out this year or next year and GDDR6 to come out next year with the new cards... hard to keep up with the new tech all coming out
that being said memory costs are insane

I just wish we would get an actual proper timeline for this stuff. All technology has a vague release date when really it's just when they go into the final phase of production preparation or something. Or that it is produced in such small quantities that it takes a full year after before we see actual products with the technology in it.
If people knew for sure that by the end of q2 next year that we would be able to buy volta with GDDR6 and also DDR5 then people woulf be able to make informed purchases.
I know that goes against their interest in selling soon to be obsolete technology but it would make things a lot clearer.
DDR4 is at it's most expensive...but if DDR5 is 18 months away before we can actually buy it...and the prices are only going to go up more...then that makes the difference whether to buy it regardless or wait.

HBM2 isn't that great, read below.
That depends on the configuration on the card, ie. how wide the memory interface is. A 1080 Ti with GDDR5X 11Gbps uses a 384-bit memory bus for 484GB/s bandwidth. Just replacing that with 16Gbps GDDR6 chips would get us to 704GB/s bandwidth.
Now for HBM2, Vega 64 has a memory bandwidth of 484 GB/s (interestingly the exact same value as a 1080 Ti). So basically, GDDR5X 11Gbps could already match HBM2. Of course you could double the HBM2 memory bandwidth by using more stacks, but that costs a lot more money as well. IMO GDDR6 is superior from a simple cost/performance standpoint, and unless you actually use 4 HBM stacks, also in performance alone.

Depends on the amount of memory. Where HBM2 shines is a lot of memory, if they made cards with it.
Take the Tesla V100, with 16GB of HBM2, at 900GB/s. That's with 4, 4GB stacks.
GTX 1080 ti has 11 chips, could do 12 (Titan). If they did a card with that many stacks, the speed could be around 2800~GB/s
But that is highly, or i'd even go as far as to say simply, won't happen.
Or, if they simply matched the GTX 1080 ti/Titan memory of 11-12GB, the speed would be around 700GB/s
Personally, GDDR5/x/6 doesn't excite me. Every time they announce something new, all i see is bread crumbs
I mean, GDDR5x is already able to do 14-16Gbps, as stated in this article, and GDDR6 is....going for 16Gbps......i simply do not seen the innovation, aside from efficiency.

Even DDR3 price has sky rocketed for a while, back in February 2013 I've bought my last DDR3's for ridiculously small price, 3 kits of 2x 4GB (24GB total) Patriot Viper 3 series (Black Mamba Edition) 1866MHz PC3-15000 model: PV38G186C9K, 1.5V, CL9... just one month later price has gone some 50% higher here, but now DDR3's with similar specs are insanely expensive here, you got to sell one of your kidneys now to buy 6x 4GB DDR3 1866, at least here where I live.

The main difference between HBM and GDDR/X is where the costs are.
For HBM, the board itself is much less complex, but the memory costs more to manufacture and implement (interposer).
For GDDR/X the board is costly with 384/512bit interfaces. The memory chips themselves are bought 'en masse' and can be binned, and are therefore cheaper than HBM.
HBM3 will be a doubling of the speed also iirc.
If they can use the small interposer tech from Intel to connect the HBM to the GPU, that would be a lot cheaper for AMD in the long run.
edit : I'm not dissing GDDR/X, its fine for the moment. Up to 128bit its the only way to go.
HBM is the way forward though. A single stack is equal to 256bit GGDRX, dual stack is equal to 512bit GDDRX.
GDDR/X does over clock better though in general.
