Here's a sheet I found online I used to help shop for a used card: https://docs.google.com/spreadsheet/ccc?key=0ArCtGVODPUTtdEdEUjRiSFdyckZ1Q1dGNUI3bkd5R1E#gid=0. I believe Asus and Gigabyte AMD card warranties are based on serial. (Eventually settled on an Asus 7970 DCII for $200 shipped that wasn't used for mining.)

I was wondering about that. It's hard to imagine having a lifetime warranty on something that is basically guaranteed to fail, but likely after several generations of improvements. PNY's "lifetime warranty" is a joke. It's the lifetime... of how long they sell it. Sometimes they say 3 years, sometimes they say lifetime warranty, for the same exact card.

Beautiful Ninja posted:Memory bandwidth from the benchmarks I've seen matters more than raw VRAM size I get that part but isn't asset complexity and detail pretty much proportional to VRAM? Its a catch-22 for game devs and even GPGPU applications. If you don't have the VRAM, you can't/won't code for that kind of use. Plus, isn't 4GB VRAM pretty much on par with current gen consoles so game devs wouldn't have to tier their assets as much for PC vs Console ports? Again, not for resolution's sake but asset complexity's sake.

For example, 4 GB 760's and 770's are an almost worthless expense over a 2 GB. Where something like the 500's series cards it was the opposite problem - it would choke from the lack of vram. I kind of doubt it's going to affect game development very much though. I'm pretty sure they're trying to push the limits as much as possible without much regard to something like mid grade nvidia card memory limitations, since there are plenty of cards without that particular bottleneck. But like was said, it's very likely to change in exactly this way, but since it requires a change in architecture it won't be in this lineup (or if it is, it'd be a new part number, like 770ti or something)

Unless I'm mistaken here and there -ARE- games that use >2GB of VRAM for game data. Games that are popular??? From what I understand vram is used to store textures to be calculated and then also completed frames. However, both of those things are directly affected by resolution and game settings, and thus the size, and can be indirectly seen by benchmarks (both FPS and frame variance). Once you get past 1080p, games do definitely use more than 2gb of vram (like Crysis 3 can use 3 gb at 1600p, and BF4 even can consistently use over 2gb). However, simply increasing vram does very little to alleviate vram issues on mid-nvidia cards because even though it's putting some of that data elsewhere, the card chokes on memory bandwidth or otherwise an inability to calculate what it does have fast enough overall. Not to say it doesn't help, but by the time it does it is unplayable. I really don't think developers limit anything based on this specific issue, rather than the limitations of graphics cards overall. Since lowering settings directly reduces how much vram is used, they can code for much higher levels (within reason). As far as generations though, I'd be really shocked if this wasn't addressed in the 800 series edit: The one situation that I've always been interested in is if there is any improvement with 4gb cards in SLI over 2gb cards that on their own show very little difference.

^^^^Higher VRAM starts to become useful with multicard and giant resolutions. Currently not even a Titan has enough power to use up all of the memory. But when you add more monitors and more cards, you can get into situations where the 3gb of memory on a 780 isn't enough.Ignoarints posted:Yes, just seriously consider from me. After reading one long thread about how they treated their cards on some mining forum it'd take some cheap price like that. XFX and Powercolor both allow you to remove the cooler as long as you don't damage anything.

Which they did - today. Talk about timing. It would seem logical to benchmark those against 3gb versions in a variety of resolutions. However since these have a higher bandwidth it might not relate to 770's or 760's very well (as far as this specific subject goes), but hopefully since the particular focus for this release is pure vram size perhaps they will test the others cards as well. Especially if there is a nice improvement which is logical since 780's in SLI can probably handle a larger vram workload. So if there is an improvement, hopefully someone will compare lower cards in the same situation to see if the same improvement is present or not edit: true to form, the first review is a typical comprehensive multi-game and 3d mark examination that doesn't include comparisons to the 3gb version despite specifically mentioning that was the purpose of the card. Unless I missed something I don't have time to read all of it at work, except at the end where it says "the extra memory doesnt matter much". If that ends up being true though, I suppose we can guess that lower cards will experience the same thing Ignoarints fucked around with this message at 19:44 on May 14, 2014 |

Anyone know why all of these miniDP to HDMI cables have 'fat' HDMI ends? Is there circuitry necessary to convert DP to HDMI? I thought there was an electrically comparable mode that would have required much less hardware if any?

Ignoarints posted:Displayport is different, and transmits data on single pairs of wires to transmist data (but can use multiple pairs) where HDMI uses a fixed number always. HDMI and DVI are the same in this way and can be converted with no circuitry, however a displayport signal must be converted to the hdmi style signal. That requires circuitry which is powered by the displayport or hdmi source Ah, gotcha. Not HDMI but close enough.  I wonder if there's any noticeable lag? Not that it matters for my use.

I dont know, unfortunately converting signals within cables opens up a whole new way for a cable to suck rear end. For the record though, I've used a ton for work (mostly on apples) with no discernible issues. Even cheap rear end monoprice ones Ignoarints fucked around with this message at 20:26 on May 14, 2014 |

And I quote:quote:DisplayPort-to-HDMI adaptors and DisplayPort-to-DVI adaptors are very simple and only operate one way. For instance, when a DP-to-HDMI adaptor is connected to a PC that supports DP++ (Dual-Mode) capability, the PC senses the presence of the adaptor and sends HDMI signals over the DisplayPort connector rather than DisplayPort signals. No signal conversion is performed by the HDMI adaptor. HDMI signals are merely passed through. The unique DisplayPort adaptor capability enables the PC to connect to a variety of displays via the DisplayPort connector including HDMI, DVI, and VGA. VGA adaptors are more complex and perform active signal conversion from DisplayPort to VGA. These adaptors also operate only one way. Unfortunately, HDMI does not support conversion to other display formats as does DisplayPort.

deimos posted:Err no, HDMI is signal compatible with DVI but VGA requires active conversion. HDMI converts directly to DVI, and in the same sort of way as Displayport does to VGA. I read the paragraph in there too, it does literally say that it doesn't. That doesn't make any sense coming from what I'm assuming is an official website for the display port standard. DVI and HDMI are functionally the same when we're talking about adapters. Displayport to DVI always have some kind of chip in them. While I was completely wrong about the typical cable converting the signal (as an active cable does) the fat housings should still be to house a small PCB. Here is "Mike" explaining passive displayport adapters. http://mikesmods.com/mm-wp/?p=494 A NXP passive design is referred in there, which you can see on page 27 here http://dl.cubieforums.com/LapdockMaterials/NXP-DP.pdf I dunno what to think. Adapters give me a headache. I'm inclined to think that part of the FAQ is just plain (and inconsequential) misinformation since it specifically says no signal conversion is performed when in fact it looks like signal conversion is performed even in the cheapest $3 cables Ignoarints fucked around with this message at 22:03 on May 14, 2014 |

In a world with millions of DVI devices, and with competitor HDMI offering backward-compatibility with these devices, DisplayPort would be dead in the water without a simple, inexpensive way to support legacy displays. To address this, VESA (DisplayPort’s standards organization) added “Dual-Mode” operation to the specification, which allow the video device to output DVI-compatible raw pixel data over three of its DP lanes, and a clock signal on the other. Add a simple level-shifter to offset the data and drive it appropriately, and you have a very convincing DVI output. This is the Passive adapter. Essentially the "passive adapter" simply says HEY DP HOST THIS IS A DVI ADAPTER FEEEED MEEEEEE. And the DP Host says "OK, here's some data on 4 channels instead of my normal 1 (or two or four)", there is absolutely no conversion on the signal, there is a handshake and then barfing of data.

So that kind of cable is passive? It sure is cheap and while I do own one I'm not in a position to bust it open to see whats inside the fat end. edit: probably 'passive' quote:It should be clear that an AC-coupled 400mVPP signal cannot be converted to a DC-coupled 400-600mVPP signal riding on a 2.9V offset without something intervening in the middle. Thus, even for a “passive” adapter, active circuitry is required to handle the level-shift. http://mikesmods.com/mm-wp/?p=494 Shaocaholica fucked around with this message at 22:37 on May 14, 2014 |

Yes 'passive' in the sense that it's not doing a displayport to hdmi signal conversion. That's just a level converter for some electrical stuff. I scrolled through a bunch of reference designs and they all have it which would make sense as any displayport adapter I've ever seen has some kind of fat end on it

Don't know if anyone would know this... you know all those Youtubes where people use the Oculus Rift and the display is being mirrored onto an external monitor? Is that a "free" output or does it cost substantial rendering power on a card?

Is there even a market for these flavor-of-the-month coins? I mean, there are at least a few online stores that'll let you pay in buttcoins...but who the hell takes dodgecoins for anything? I'm glad to see the mining craze has largely stopped and the prices are coming back down, but the $300-$350 that most of the used 290X's are going for is still too much, if you ask me. I mean, they're almost all the original reference designs, which means they're only ~9% faster than a 290, and they throttle like hell due to their terrible heatsinks. You can get brand new 290's for ~$350 these days, with excellent 3rd party coolers and decent overclocking potential. So really, by the time you replace the reference 290X heatsink so you can actually out-perform the current 290's, you're already at or above the same price, and you're dealing with a used card vs a new one.
