Doesn't matter, if you read the article these chips are being designed for the Volta GPU, high end stuff for quite some time and also expensive, higher bandwith is good but lets say the PS5 ships with 16GB or ram, realistic right, the difference between GDDR5 vs GDDR6 or HBM memory, which are both much faster would be a decision that costs milions.

Overall if you look at the 1080ti on pc, which uses GDDR5X and has 11GB's of memory right now its? 800? lets say the ps5 gpu is CLOSE to that, 2 years from now right prices are 1/4th of what they used to be, realisticly, they still need to build the rest of the console, they proberbly want to aim for 399 max 499 and they want to make a CPU that is much more powerfull, lets say Ryzen if they stick with AMD.

Overall the general rule of tumb has always been, more memory is better then faster memory (within limits) but espcially for an APU, which consoles use, where memory is shared between the CPU and GPU the amount will be very important, look at the PS4 pro which has the same amount of ram as the PS4, the difference with the Xbox One X is mostly in the amount of ram, cuz it just lets you do... more stuff.

So no, theres no reason to further analyse this, the PS5 and Xbox next will not use cutting edge technology used by graphics cards more powerfull and expensive then the consoles themselves.

I understood this part. I believe you didn't understand my second questiion.

It's about if it we are going to see GDDR5 (or what they choose) on smaller chips to make a pool and increase bandwidth or if the chip will have a very large bandwidth or speed itself that a single or 2 chips would be the best choice.

Next gen consoles may use G5X, as it is cheap, cost effective, and plenty fast. Speed of RAM is usually less of an issue, anyway. The amount will be the important thing (look for 16GB consoles, next gen, bare minimum). 

G6 will be rather expensive upon launch. Yes, the Volta Titan (a card for me ) will have it, but I expect to pay no less than $1,200 per GPU.

Gotcha... and talking about GDDR5X are we looking at few chips with high speed and bandwidth or a composition of several chips to combine and make high speed and bandwidth?

And on size of the memories how much difference would we expect a composition of chips versus "bigger" chips?

Its not really about the size of the memory chips but of the size of the memory bus, fewer, higher-capacity modules are better but in most cases the size of the memory bus really delivers the biggest punch in addition to the overal GB/s performance, I think the Nvidia Pascal uses 12x 1GB so I don't think we will see bigger memory chips, but it could be possible, we dont know the future :P
