Samsung GDDR6 Memory Arriving Next Year With 16 Gbps Speeds – Designed For NVIDIA Volta

Summarizing your comments, there is a possiblity of GDDR6 if cost come down fast enough in 3 years and make the prospects of cost during the gen mean a GDDR6 is possible, but if that doesn't pick up fast enough the X will be it right? How much faster and bigger pool would you guess? 20GB and 4x faster?

It's difficult to tell, but the general consensus is that a doubling of capacity and performance for the same costs wouldn't be entirely impossible at a later date, but a more realistic goal is probably 50% gains over GDDR5X in terms of capacity and bandwidth in the shorter term. (As GDDR5X was a middle step.)
The biggest issue with GDDR6 is that it requires more masks which means the big factory's that make the stuff need larger clean rooms and more equipment, so it could take a little longer to ramp up GDDR6 than expected.
Just need to wait and see.

I know next to nothing on HBM... considering current trends and the fact we are closer to DDR type memory on cosoles usually, it would be harder to get HBM than DDR?

HBM is going to always be more expensive in general I think. So that will always keep it relegated to markets that can afford it, HBM3 just brings those high costs down more.
Still a massively long way away before HBM replaces DDR memory in all markets though.

How feasible or more interesting in cost/performance is bigger chip with higher bit count and clock versus the smaller versions? Keeping same trend we would be looking at perhaps something between 1-4GB per module on how 64 bits or more?

Well. That depends on what's available, what the price is... There is more to the cost of Ram implementation than the amount of chips or their bus widths.
In general the wider the memory bus or the more chips you have, the more traces you need on the PCB, the more traces on a PCB means potentially more PCB layers.
So you need to have a balance there between the two.

Microsoft for instance didn't reduce the amount of memory chips (But did change the ram chips it was using) between the Xbox One and Xbox One S, both have 16x DDR3 512MB memory chips. DDR3 is cheaper than GDDR5 though.

JEDEC is pushing GDDR6 to top out at 4GB per chip (32Gb, 8 bits in a byte.), 16Gbps. - On a 256bit bus with 16x chips you are looking at 512GB/s of bandwidth with 64GB of capacity, consoles will probably have half that capacity though due to costs.

It took a long ass time to move from GDDR5 to this one for modern tech standards...

Indeed.
GDDR5 dropped in 2008 with the Radeon 4870 debut and has stuck around right up until today.
Although AMD and nVidia did boost clock rates, they did increase the bus widths from 256-bit to a massive 512-bit in some instances.

Considering PS5 could sell close to 100M consoles and that it would mean over 100M chips per year that could help make it goes down in price... like how PS4 "lucked out" with GDDR5 that were expensive, but just on the brink of releasing they could double the memory of the console based on reduction of cost.

But I comprehend the enhanced complication to produce.

With the improvements you expect from GDDR5X then we are more likely to have smaller modules and more quantity then?

About HBM... then considering we know that consoles is always how to have the cheapest as possible to meet need then HBM is quite unlikely when faced with GDDR5X =[

On the layers for more modules... considering PS4 were able to have all those layers and still have small board on budget price, 16 chips of 1 or 2GB of GDDR5X wouldn't be an issue when talking price only.

My bad from going off-topic... but I think 16GB would be to little for PS5, 32GB is closer to reality IMHO.

32 GB??? XD holy crap and you expect it to be expensive GDDR memory also, most high end pc's don't even have that much if you compare the normal ram+the video ram, that is a completely unrealistic expectation lol

Well people put it before to you... PS4 launched with 8GB of GDDR5 while the common place was high end GPU to have less than 3GB but the CPU would get both close to 8GB total... when I say 32GB is because I think only doubling the size compared to PS4 (or 50% against X1X) seems quite small jump. But if we are talking on they deciding to perhaps separate the memories perhaps 16GB (4x PS4) for games on GDDR and 4GB DDR for UI could be likely... But I think Sony will keep unified RAM as that helped them make the development of games easier.

Rememba the PS5 is likely November 2020, exactly ~3 years from now

Things can change a lot. From the time the GDDR5 cards came out, to the launch of PS4 was also ~3 years, and they had only 1-2GB ramz. When the PS4 came out, 2-4GB was commonplace. (PS4 2x)

I think 16GB ramz will be the standard in high end gpus around 2020 (this is the gen after Volta/Navi), but the PS5 will have double the capacity. And it's either gonna be 4x 8GB stackz, or 16 x 2GB modules in clamshell mode like PS4. If not, then at the lowest specs, I'd expect 24GB ramz.

People need to dream bigger lol, when you search for discussions from 2011-2012 on enthusiast gaming forums how much ramz next gen would have, most said 2GB, 4GB to be the absolute maximum.

Yep I was one surprised they gone from 512MB (which was already a surprise on PS3 reveal) to 8GB on PS4... and considering PS3 gen survived more than any before and this one doesn't look like will survive less, I think the next one shall also survive a lot as we get closer to need preposterous jump to see a difference in IQ... so I keep my narrative that unless sales plummet for SW this gen will go at least 2020 as you said, maybe even more. And Sony will release PS5 only when they can make a big leap on a 399 console, something like 16-20Tflops on more efficient GPU (gaining that 10x over PS4 and 5x PS4Pro) on a 32GB RAM.
