But the link in the OP says 768 GB/sec with a 384 bit bus
And the Titan Xp has 547.7 ( at 11.41ghz ? ) 547.7 * 16 / 11.41 = 768?

But they do actually have all 3 in PCIE form

P100 ( no video port )

http://www.pny.com/nvidia-quadro-gp100
GP100 ( yes video port ) 3584@1430mhz and 720 GB/sec and 1/2 DP units

http://www.pny.com/nvidia-quadro-p6000
P6000 or basically Titan Xp at 1560mhz and 432 GB/sec and 1/32 DP units

http://ambermd.org/gpus/benchmarks.htm
The first bench has it winning by 3% despite lower cores despite the deficits.

The 3200 posts and join date seem to contradict that, but there is simply no other explanation on how you think the R9-500 series is the first to do that *cough390Xcough770cough* or that it's somehow an AMD exclusive.

There is also no other explanation on how you think a rebrand/refresh is worse than the things nVidia has been doing lately besides potentially just not reading any news articles on OCN. 970 anyone?
AMD doesn't get royalties, it's a JEDEC standard. And nVidia does use HBM.

Either way Samsung announced GDDR6 for 2018 back in August and Micron in February, soooooooooo this isn't actually news aside from Hynix joining the game which we all knew they would.

GDDR6 is not impressive btw, the only thing it has going for it over HBM2 is >16GB VRAM. It ties or loses in every other metric.

Never did I say this was the first time. You must not know what year it is or must group every instance together as if it happened yesterday. What company gets complained about from year to year changes over time. Right now it's constantly NV but I'm not seeing the same reaction from fanboys in the other camp.

Because there isn't much to get mad about? It's a rebrand. The 390X did it, the 280X did it, the 770 did it, and so on.

In comparison we have the 1060 3GB, the 970, Geforce Experience needing email, no beta drivers on the site; only in GE (is that still a thing?), FE cards in general, Gameworks (which they finally did open up - kinda), no SLI at all on 1060 and down, no 3/4way SLI period for games without hacking at it, Pascal lasting only a year when pushed to the limit (per nVidia) and only 5 years stock (per nvidia).

But don't worry, a rebrand is much worse. rolleyes.gif

Count how many started with the 10-series. They get lumped because it's one after another.

EDIT: Lol, have to update my list, another extension on the GE train;
http://www.overclock.net/t/1628748/ghacks-nvidia-geforce-experience-security-vulnerability#post_26040099

Granted people wanting to do harm will always find a way and it should be fixed already, but see what I mean about it just being one thing after another?

One of the problems with GDDR5 is its power consumption, pushing 50+ watts for an 8GB config on GPUs. I wonder what kind of power we are looking at with GDDR6?

Nvidia has the Titan brand. Seems there are enough buyers with amounts of cash to buy it. Yet I seriously doubt Nvidia would stay with 12 Gbps GDDR5X if GDDR6 gives so many advantages. Nvidia ts more clever to hold back like that. They are similar to Apple and have shown to know how to claim pre-production contracts, see HBM2 and their DGX-1 workstaions. Nobody else could secure so much of this rare memory.

If there is a production based limitaiton, I would seek it in the used process node. Nvidia would rather limit the amount of cores in a node like TSMC 12nm and bring new edtions than to let the bandwidth be starved when AMD writes it all over their marketing.



Nvidia could adopt a 12gbps first and later another year release the same GV104 with updated G6 memory configuration. Just like what they did to 1080 & 1060.


Furthermore I am sure G5X will be cheaper than G6 at the start, and they could leverage the earlier launch date with just G5X before G6 comes in at 2018.

GDDR6 is said to have 10% lower power consumption than GDDR5 at more than 50% more bandwidth. It goes into the right direction, but sitll not equal to HBM. Although the mainstream should benefit the most from this. Stacked memory is just to expensive for the average card out there. So, I guess the change is better than nothing.


@ KyadCK
Nitpicking won't help. Non of the issues you mentioned are as bad as lazy rebranding. And to make matters worse, AMD has been the Rebrand king since a few years. Some Radeon models even got rebranded several times. Look at the whole series level, getting Rebranded way too much. See HD6000 series, then R7/9-200 -> 300 and now RX400 -> RX500 series. Nvidia had their rebrand too, but outside of mobile chips or low-end OEM models, it weren't nearly as much as AMD did in the recent years. There is no excuse for denying the customers new hardware and try to fool them too. Nvidia at least hat the dignity to lower the tier of the cards going from 80 to 70 and 70 to 60 a.s.o!

AMD is not even thinking about his and just patches everything ab by the first number. If you bought a R9-290/290X in 2014, you still haven't gotten the chance for anything faster, low availability and high prices from Fiji aside. Try to knock at that door and make your favorite company a little more fire under their lazy butts. They either bring nothing, the old crap, or it takes forever - like Vega. rolleyes.gif

If they were more open to other memory technologies, the whole waiting game could be shortened, if not elminated.

Very unlikely. A jump from 11 -> 12 Gbps is not enough for a new series. If Nvidia brings new cards, they will bring new tech too. The 1000-series got their mini-update and as good as every model as possible.

Like I said, the lower to mid-end might get the GDDR5X treatment while the upper tiers move up to GDDR6. The highest Titan model might get a HBM2 configuration again, but I can't say if this is coming for us consmers too.

That depends on which tier of cards Nvidai brings first. If the 2080 and 2070 are first, some of them might still have GDDR5X onboard. If we are lucky there will be an updated card in the 1070 territory on tier lower as 2060 with GDDR5X too. Everything above will be equipped better. Nvidia is known for their contracts with the suppliers. if they want GDDR6, they get it in advance like Apple. They could even secure more HBM2 for their professional line than AMD could in the whole year.

50W? Sounds pretty high. I don't think a 290X with its 16 ICs pulled that much. I think an Anandtech article I read some time ago estimated its power consumption at around 30W. What we do know is that GDDR5 ran at 1.5v. GDDR5X runs at 1.35v. The article says that GDDR6 will run at a 10% lower voltage than GDDR5, so that's 1.35v. We're basically getting more performance at the same-ish power consumption as GDDR5X.

IIRC it was 5 to 6W per 2GB GDDR5. HBM had about 60% less consumption. [EDIT: roughly 5-6W per 1GB normal GDDR5]

But from all I read GDDR6 is said to consume less than GDDR5X. Its a first that this should be the voltage only. Let's find out what it really is.


Edit:
I looked up an old Amandtech-article.

http://www.anandtech.com/show/9883/gddr5x-standard-jedec-new-gpu-memory-14-gbps

At 256-bit an 8GB GDDR5X consumes about 20W, which would equalize 2,5W per 1GB.

Lol I'll take rebrands over anti-consumer garbage practices any day of the week. Turning Nvidia's software suite into a walled garden like this is not acceptable in my eyes. Rebranding an RX 480 into a 580? Eh, who cares? Process was refined, clocks have gone up, and it's slightly better overall. Worth an upgrade? Obviously not. But if you blindly buy something because it's shiny and new I have no sympathy. In fact, it's the people like that who encourage hardware manufacturers to do this, especially Nvidia. They are the people who turned the Founder's Editions into the best-selling models, and they are the reason Nvidia can release multiple Titans per generation. I'd much rather see an AMD GPU monopoly than an Nvidia one, solely because we've seen how Nvidia behaves when they just have a lead. Intel has had far more of a lead in CPUs for years but they've never stooped to this low a level.

We will have cards using cheaper GDDR6 and cards using HBM.

Just like it was before rolleyes.gif

IMO* As long as foundries are focusing on ddr they don't really have to change much in terms of production.Changing the focus to HBM would mean changing over production lines. In essence it's cheaper to use what they have and make minor changes to the line than it is to change the line.
