Wiggly Wayne DDS posted:No it's synthetic tests where people allocate all of the memory at once. There are posts where people find it happening in games if you push enough, and a reluctance for the card to allocate more than 3.5. But it's pointless to keep running in circles about it unless there's new information, or a complete debunking by NVIDIA or some other authoritative source.

Is it exceeding that much in use, or exceeding that much in transfer size? I may have misunderstood the NVIDIA statement.

Getting a 970 in a few weeks, i'm only playing at 1080p and I don't go crazy with downsampling and aa and poo poo. Is there a cheaper card that may do what I want? Is the 970 overkill for what I want? I have a 660 GTX right now and want to stay with Nvidia.

I don't go crazy with AA or DSR (well...most of the time) and I feel a 970 is perfect (I'm at 1080p also). Hell with the right Skyrim mods I can't even get a solid 60 fps all the time (but ENB tends to do that). A cheaper option would be the 960.

The 960 is more comparable to the 285 than the 280 because of the amount of RAM. Just be warned, the 285 draws like a little less than hundred watts more power at full load than the 960. http://www.eurogamer.net/articles/digitalfoundry-2015-nvidia-geforce-gtx-960-review

TBH, I am ignorant of the details, which is why I ask. At the very least, we know that AMD is about to leave nVidia in the dust with regards to memory bandwidth. The next high-end cards that AMD will release will feature Hynix's stacked memory modules. You may remember several years back when nVidia was touting their own stacked memory products which were then delayed to Pascal.

They will now shoot to use the joint AMD-Hynix High Bandwidth Memory (HBM) instead. The first generation of HBM products which is touted to, on paper, permit memory bandwidth 1 For comparison's sake, a GTX 980 has only a 256-bit memory bus. A Titan Black only has a 384-bit memory bus. (The Titan Z also only has a 768-bit memory bus, but that's a dual-GPU card, so still, 384-bit per-GPU.) All the memory efficiency and color compression touted by Maxwell is about to be obsoleted by this advancement. We should not expect 1:1 performance improvements due to the increase in bandwidth, by which I mean that the full-fat Fiji XT should not suddenly triple the performance of a Titan Black. But it gives AMD a serious leg up, as nVidia will not bring non-planar memory products to the market for at least one year. SwissArmyDruid fucked around with this message at 04:18 on Jan 25, 2015 |

Boiled Water posted:Where are AMD putting all those watts? 100 watts is a lot of heat. Nvidia made all sorts of optimizations to improve performance/watt going from Kepler to Maxwell and claimed a 2x improvement which is why Maxwell is so unusually power efficient when compared to other recent modern graphics cards. Normally this wouldn't be totally necessary for desktop GPUs but Nvidia and AMD have been stuck on the 28nm process node for longer than usual. This means that to keep increasing performance you need to either increase the TDP to higher than usual levels or have an especially power efficient architecture. AMD chose the former path and Nvidia chose the latter, I am assuming that AMD assumed when they started working on the architecture that they wouldn't have to release the 390X on 28nm but later were forced to due to delays at TSMC. The delays aren't as big of a deal for Nvidia because since their chip is so efficient they can build some massive 600+mm^2 beast approaching 10B transistors and still have it draw no more than maybe 225-250 watts whereas AMD's beast chip is supposedly going to be pushing 300.

Update on my Gigabyte GV-n970WF30C-4GD http://www.newegg.com/Product/Product.aspx?Item=N82E16814125685 (the overclocked one WITHOUT) the back plane. (click on my thread history for other little notes) I was having trouble boosting the memory speed at all. I bought some tiny heatsinks with adhesive, they were the wrong ones, way too tiny, so I stuck 2 on each of the 4 exposed memory modules on the back of the card (the ones on the front touch the main heatsink. As a result I'm currently running at +400mhz (3905 effective). They've only been at that speed for half an hour or so, but so far so good.

Are they at such a legitimate technological disadvantage that Nvidia could rollout first gen HBM on the 1000s just as AMD drops second gen cards with better thermals/consumption? An argument could be made for the 380X using HBM as well. If AMD's implementation of the memory controller involves placing the entire HBM package directly onto the GPU die, as opposed to breaking it out to a second package, yes, that might explain where the extra heat is coming from. I don't think this is likely, though, at least, not until the second generation of HBM products. The first-generation HBM products offer 1 GB of memory in a stack 4 wafers tall. To get the kind of memory capacities that a GPU needs, you'd need one stack per GB of conventional GDDR5, and that would make the die size balloon out of control. No, I think that if they're going to do that, it's not going to be until the gen 2 HBM parts. Those are slated to come in formats stacked either 4 or 8 layers high, in 4 GB or 8 GB per stack. PER STACK! Just imagine what that would mean for AMD's APU parts, which have had trouble scaling their performance higher because of how bandwidth-limited they are. AMD has basically not been putting as many GCN cores onto their APUs as they COULD be putting, because the latency and bandwidth from talking to DDR3/4 just isn't usable. But to answer your question about nVidia reclaiming a lead: Any advantage that AMD develops or maintains will, I think, depend entirely on the implementation of the memory controller going forward, whether the HBM gets mounted directly on the GPU die, or on separate packages similar to what we have now. Regardless of how they do it, I think we can expect much smaller cards, physically-speaking, since there won't need to be as many chips on the board to parallelize DRAM to enable throughput. AMD has been sampling these HBM products since, I think, September of last year. That's a lot of time on top of until when Pascal comes out to play around with the optimal layout for GPUs. If they play their cards right, they should be able to grow this lead into a good gain of market share. But I think we won't be able to know for sure until we see Bermuda XT. (390X)

I'm a bit less expectant that HBM's going to ~revolutionize gaming~ so much as I think it's tailor-made to make it so FireGL cards finally have a trump card to hold over the Quadro for a while. If AMD can be first to market with a workstation graphics card that has 16/32/64/128GB of sufficently-fast buffer on it, no one's going to loving care about the TDP.

At least for bandwidth between the GPU and VRAM. Increasing GPU to GPU or GPU to CPU bandwidth by heaps would probably be a big deal but HBM won't do that. Kinda surprised they haven't already put a couple 40GbE or 100GbE fiber ports on those card already to let them talk between each other faster without waiting on the CPU or the PCIe bus.

Umm, question from someone without too much GPU knowledge, but what happened to the Asus 780 ti UCII cards. I bought one a while back for around $700(AUS) and recently have been wanting to get a second one to SLI with. Only issue is, I can't find a single PC shop that stocks them. And looking on Ebay. I only see one being sold for $1200. So I guess my question is... what happened to the card market-wise and also, does anyone know where I can obtain one for a reasonable price?

I have an MSI GTX 760 4GB card, Core I5 2500 CPU, 16GB RAM, Windows 7 64. I installed MSI Afterburner and followed the guide in this thread - I didn't actually get that far into it, I just set it to temp priority at 80 degrees and made a custom fan profile. I went from 25-30fps on medium settings in Metal Gear Solid Ground Zeroes to 60fps on high settings. Now, though, whatever game I play, after about 10-15 minutes or so the fps will suddenly drop to 10-15 and when I quit back to desktop, Afterburner shows the GPU usage at 97-98% and the temp stays at 80%. I have checked for any processes and causes of GPU usage but there is nothing I can see. When I restart, it goes back to normal and Afterburner shows usual desktop usage of 0-10%. The temperature also normalises and drops to about 40 degrees or so after being idle for a few minutes. As soon as I play a game (I have tried Ground Zeroes and Payday 2) the same thing will happen again after about 15 minutes or so. I put Afterburner back to default settings but that made no difference. I have uninstalled it (and Rivatuner Statistics Server which installed alongside) and again that made no difference. I have uninstalled and reinstalled my NVIDIA drivers but again I have the same problem. Strangely, even after doing so and resetting, I was getting 60fps in Ground Zeroes before the slowdown which makes me think that there is a setting somewhere which is still enabled. Does this sound like a software problem or do you think it's the hardware on my 760?

I may be completely underestimating the horsepower requirements of MGSV, but I have a really hard time believing a 760 had an average of 25-30fps on medium in it. If I remember correctly it's slightly more powerful than a 660Ti and less than a 7970. You may have a hardware issue. Or MGSV could just be optimized like complete and utter crap, but a simple overclock should not allow you to double your framerate while increasing your settings.

There might have been a pre-existing problem which I temporarily alleviated by whatever Afterburner did, but unfortunately now I can't play anything else whereas before, it was only Ground Zeroes that gave me poor fps. The only other question I have before I think about getting a new GPU is: could the motherboard also be the cause and/or make the card run at an underclock? Instinctively it seems not but I wouldn't want to take the plunge on a new GPU and then realise that in fact it's the mobo.

The ML07B is not one of the low airflow cases I was talking about. It is an incredibly well engineered case that manages pretty drat good cooling - it has 3x120mm fan slots, although you have to supplthem yourself - combined with the small dimensions that makes for some serious airflow. In addition, the intake for a non reference graphics card is hard up against two of the fan vents, creating almost perfect conditions for a non reference cooled graphics card. You'd be shooting yourself in the foot buying a reference design card. Also - the ML07B is virtually identical in layout to the RVZ01, other than cosmetic differences, they are the same case - Except the RVZ01 comes with two of the three fans preinstalled, and it comes with dust filtering for all the intakes, something you can't get on the ML07B.
