I forget how insular the community is here. Completely oblivious to actual market trends and realities.

You mean like the 1080 Ti and Titan Xp which both use GDDR5X and run 4k very well.

 

[Kaapstad]

They run it 'ok'. They're borderline if you want to do 60fps in nearly everything with good settings. Some games you're gonna have to make more notable compromises.

And games will get more demanding. These two cards you mention might still be 'ok' for a couple years, but for those who really want to push 4k *comfortably*, we definitely need more. Extra horsepower will obviously be the biggest thing, but if super high bandwidth HBM offers notable benefits at these high resolutions, I would imagine consumers, especially enthusiast consumers like those here, would want that. I find it absolutely bizarre that some of y'all are pushing against this.

Combined with GDDR6 for the x70/x80 cards, I think it would create a pretty great 'high resolution-capable' lineup.

Maybe GDDR6 will still be used, though. Of course it will still be 'enough', even GDDR5X will be 'enough', but who pays top dollar for 'enough', ya know? A bit of overkill ala the Kepler and Maxwell Titan's is not necessarily a bad thing.

Something most people don't even consider when talking about memory ability is GDDR5X is more than fast enough @2160p for 4 way SLI with a stack of Titans. Don't forget that in SLI the memory is mirrored on all cards and with 4 cards in play the fps even at 2160p is very high. The biggest problem I find with mGPU is not the memory but how the cards are connected when using 4 cards, AMDs solution using the PCI-E slot is bad as it has to share that bandwidth with the normal GPU stuff and NVidia are not much better where there are no HB 4 way SLI bridges.

 

[Kaapstad]

I think the market for 4way SLI or even 2way SLI for that matter is so low it's just not worth there time.

That is not the point I am making.

I am pointing out that GDDR5X is capable of dealing with very high fps @2160p, far more than a single card can produce on its own.

 

[Kaapstad]

To put it in perspective:

256-bit at 14 Gbps = 448 GB/s bandwidth

That's pretty impressive for 256-bit.

Though I wonder if this is enough for 4K60. We haven't had the chance to see any 600+ GB/s cards yet, to see if extreme memory bandwidth really makes a big difference at current compute power.

Volta might also have better memory efficiency though too.

Yes we have and they are very fast.

 

[Kaapstad]

Come 2019 a Volta Ti will do everything at 4K but it will be a fairly large chip and will be expensive.

Unfortunately Volta is nowhere near powerful enough to max out 4K.

 

[Kaapstad]

why have nvidia stopped doing refreshes?

500 series was 400 refresh
700 series was 600 refresh
both 900 and 1000 series new tech introduced

A number of 10 series cards have been refreshed with faster memory like the GTX 1060, 1080 and Pascal Titan.

 

[Kaapstad]

Shiny is so hard to resist at times, it just has to be bought even if it isn't needed

The Titan Xp is a beast even on the stock air cooler.

 

[Kaapstad]

OK. Realistically how long before we see Volta. And more importantly how long till we see the "2080Ti" or whatever it will be? That, for me I think will be the first no compromises 4K card. Thats what I am betting on. Assuming the "2080" is about on par with the 1080Ti as is usually the case.

Probably sometime around March 2018 for the mid range cards and August 2018 for the Titan. The Ti will probably turn up about 6 months after.

This is based on what NVidia did with Pascal.

This also means that there won't be any big jumps in performance until the arrival of the Titan.

 

[Kaapstad]

The titan is off the cards for me. I don't see it as good value compared to the Ti. In fact... God-awful value.

If someone has already got a 1080 Ti I don't think they will see anything noticeably faster with Volta until the Titan turns up in 12 months time or the Volta Ti in about 18 months time.

The best anyone is likely to get with the Volta mid range cards is about 25% over the current 1080 Ti which makes upgrading not very appealing.

 

[Kaapstad]

I think that would be a push? was the 1080 not equivalent to a decent OC 980Ti?

It's complicated.

If you overclock both the 980 Ti and 1080 the Pascal card is about 25% faster.

If you run a Kingpin 980 Ti on LN2 it will beat any 1080 on LN2.

Maxwell is more efficient per clockcycle than Pascal.

For normal use though a 1080 is about 25% faster than a GTX 980 Ti.

 

[Kaapstad]

You mean like the way we heard about the Titan Xp?

I was very impressed by the way the Titan Xp managed to get past all the clickbait and rumour mill sites.

How could they miss the fastest gaming GPU product launch lol.

 

[Kaapstad]

Don't think we will see any HBM gaming cards from NVidia now that GDDR6 is available.

I hope AMD also start using GDDR6 for their future cards.

 

[Kaapstad]

I can't see this happening.

AMD's cores badly need the power savings (to budget more to the core) and the extra memory bandwidth vega's design is staved of it), AMD GPU need R300 or a Tesla like shift in design to fix this and get back on top.

Which I hope Navi will be so they can use more cost effective GDD5X/GDDR6

There is no reason to stop a GDDR5(X)(6) card from using a bit more power than a HBM based one. There are also advantages too in moving the memory away from the GPU core as it makes cooling easier and higher clockspeeds more possible.

If the next round of AMD cards do use GDDR6 and consume an extra 20 watts who cares if it means the cards are easier to manufacture and there are plenty of them on the shelves.

 

[Kaapstad]

It all depends, 20w on a top tier 250w cards is not much in the grand scheme of things but when your memory controller and ram is sucking up 1/3 of the boards TDP like with RX480/RX580 it makes you wonder how much performance is being held back to get inside the typical board TDP's of 250/150/75w.

I thing it be better for AMD to come out with a 5970 type product, ie top quite taking the performance crown but 90-95% of the cutting edge performance on a smaller cheaper to produce chip which much less power consumption.

Its happened in that past when nvidia (NV30/Fermi) or AMD (Rage128/R600/Vega) have come out with big hot power hungry stinkers they had to start from scratch to get back in the "game" so to speak.

I think design is more important than how many watts a card pulls, the GTX 480 was just a very poorly designed card as it used less power than a lot of todays top end cards yet it ran very hot.

In the games that do not use asynchronous compute, the Titan V is barely any faster than a Titan Xp.

Rubbish

The Titan V is about 33% faster on average

With async compute the difference is more like 50% to 100% faster.

 

[Kaapstad]

I think I will just carry on with my old cards.

 

[Kaapstad]

Lies !

Titan V is total rubbish but better rubbish than the other options.

 

[Kaapstad]

There is a certain stubbornness in approach that is holding the architecture back - for a long time holding out for when games make optimal use of a future vision for the architecture and it simply isn't happening - even with the hardware in consoles it isn't coming around like people would like to see and with nVidia so dominant it just ain't happening.

With a change of focus on the implementation so that it is better loaded up and less under-utilised by the type of processing it has to deal with here and now today (and on a better node than GF 14nm) it would still compete with anything out today or likely even the next generation.

Congrats on the MOH.

Did it come as a surprise when you logged in.

 

[Kaapstad]

Most likely. It's a lot of money but then I can stop thinking about it. It's not like I have any other expensive hobbies.

You are not married then.
