Good. I'll just hold out a few more years on my sli gtx 760. At that point anything I buy will be a big upgrade biggrin.gif.

No, that was relating to the size of the memory controller in the the GPU-die. I admit my post may have been a little bit out of context. HBM has lower space requirements than GDDR5. It was big news back when Fji hit the market.


Thanks. I will read that soon.

A good architecture meeting a supreme memory technology would be more beneficial, yes. GCN is ripe for a general overhaul. And I doubt this can be done with Vega alone. Maybe Navi will have what it takes to fix all the construction sites the Radeons have.

HBM1 had issues in certain games if I remember, and honestly after GDDR6 gets OC'd HBM2 is NOT that much faster... like maybe 150 GB/s if GDDR6 oc's well. and I love Hynix as a company. so I think I will indeed be rolling with Nvidia and GDDR6

memory had issues in games?

HBM is more than better bandwidth. Lower footprint, Lower power consumption. And you'll have to wait another year to get Gddr6. HBM2 might be available in the next graphics card released.

HBM or GDDR6, either way Hynix is laughing all the way to the bank! biggrin.gif

post #59 of 108
I was brain storming the other day with a cup of Cafe Bustelo and this is what I arrived at:



With GDDR5X they have the potential to go up to 16 Gbps. We have yet to see 12 Gbps, 13 Gbps, 14 Gbps, 15 Gbps or 16 Gbps used or revealed. This GDDR6 operates immediately @ 16 Gbps.

NVIDIA is planning to release Volta, but we haven't heard anything regarding what succeeds Volta. Considering this, I immediately thought back to Kepler when they refreshed the 670 and 680 (760 and 770), and they dropped the 780 Ti and Titan Black with faster memory than the 780 and Titan.

My thoughts here is that, they retain the ability to use faster memory for a possible Volta refresh. This will allow them to have another product stack to release instead of rushing out Volta immediately with the fastest memory they can use.

For example;

2080: GDDR5X 12 Gbps
2070: GDDR5X 11 Gbps
2060: GDDR5X 10 Gbps

Then they release the Volta Titan (Cut Down): GDDR5X @ 15 Gbps

Time passes until 2019, and refresh;

Volta Titan Black (full GV102 chip): GDDR6 @ 16 Gbps (if it has GDDR6 on the box, it would look great, especially if all the other cards carried G5X; would be a huge differentiator)
3080 Ti (slightly cut GV102, same or slightly more than original cut down Volta Titan): GDDR5X @ 15 Gbps (to have the Volta Titan Black distinguish itself from the 3080 Ti)
3080 (more cut down GV102): GDDR5X 14 Gbps
3070 (full GV104 chip same as 2080): GDDR5X 13 Gbps
3060 (cut GV104 chip same as 2070): GDDR5X 12 Gbps

Volta is also rumored to be on 12 nm, meaning that refresh means the manufacturing process has matured, resulting in better binning, higher clock speeds and higher memory speed (770, 780 Ti, Titan Black - because remember Kepler was a die shrink). Another great example of process maturity is Maxwell. Nevertheless, NVIDIA hasn't done the whole refresh thing in ages and there is nothing that follows Volta as far as we know:



Which is the only reason why I am considering the refresh option, because we haven't heard so much as a peep about what comes after Volta, not even a mention of a code name.

Again, I do not think that the consumer side will see HBM used. GV100 will most likely use it, but for enterprise applications only. Since we have all of this new GDDR memory technology, I doubt that NVIDIA would opt for HBM instead, since this GDDR5X and GDDR6 has less cost involved.

@ BiG StroOnZ

Nice thoughts, but Nvidia does not have that much performance advantage to dally around. AMD can free some potential performance which is limited right now by GCNs horrible bandwidth starvation.

If Nvidia will do anything, tinkering around with the process node is more predictable. It could be something like this:

Volta 1st Generation - 12nm TSMC (release 2017 / 2018)

Titan XV
--> 16-24GB HBM2
--> 550-600mm²


GTX 2080 Ti
--> 12-16GB GDDR6
--> cut-down Titan XV


GTX 2080
--> 10-12GB GDDR6 (?)
--> 300-400mm²
--> faster than GTX 1080 Ti


GTX 2070
--> 9-12GB GDDR5X @11+ Gbps
--> cut down 2080
--> equal or faster than old GTX 1080


GTX 2060
--> 8GB GDDR5X @11+ Gbps
--> former 1070, now slightly improved
--> lower TDP / power consumption


GTX 2050
--> ??? not enough data ???
--> new <75W TDP card
_____________________________________________________________________________________________

Volta 2nd Generation - 10nm TSMC (refresh + shrink end of 2018 / 2019)

All cards getting GDDR6 and DIE-shrink to 10nm with more CUDA-cores (shaders).
Potential GDDR5X models get higher Gbps-updates and general improvements.

i don't think we have enough information beyond this. Some GDDR5X models could get the GDDR6 update earlier. At this point it is more a guessing game. The numbers are put together with the knowledge of past generations, Pascal included. Pull in any number you see fit. Right now I don't know where GDDR5X is even going in the future. Upper limit of the memory is 14 Gbps. I doubt it will have a future in the upper tiers when GDDR6 can put up 16 Gbps instantly and is more energy efficient.
