I meant volume in terms of space. Noise is caused by turbulence and has a lot to do with with the construction of the blades and where the air is getting forced to go. There's also stuff like bearing whine and housing vibration but for most circumstances they'll be overwhelmed by the sound of air getting forced to change directions. To get really thorough though, in general you probably could make blowers quieter because they can move air through restrictions better so a baffling system would able to be more powerful than with a conventional axial fan. Also the benefit of high pressure letting you put it on the far end of a duct somewhere. It doesn't really work out like that with computers though, a large low speed thin fan fits nicer than a blower and noise reducing baffles would into the space available on a videocard.

I just went from slightly-underclocked GT9800 to GTX 660, and let me tell you -- the performance increase is huge compared to previous update (7900GT->9800GT) I did. I can increase detail level and resolution/AA and it's still noticeably faster than before. And it only uses slightly more power than the previous card. On the other hand, it's a testament to G92 chip that it could run most games at playable frame rates almost 5 years after it's release.

I went even further than that, 8800GTX -> GTX 680, I was utterly blown away. Having said that I too was really impressed at how well the 8800 was still holding up. The only thing that really pushed me to replace it was getting a new monitor at 1900 x 1200 which was really taxing it, and occasional artefacting I was getting from overheating, which was mostly alleviated by giving it a drat good clean.

Does anybody have a 7850 card, and have a problem where the fans spin up every 10 seconds or so when the card is in long idle (black screen) ? I have an MSI twin frozr IV 7850 that does this, and not convinced getting a replacement is going to solve it (seems very much like the Radeon Spin up bug).

Factory Factory posted:Some consoles already enjoy heterogeneous compute. The PS3, for example: the Cell processor is a big execution core (CPU-like) with a number of coprocessors (GPU-like) on a single die. And the PS3 is a real powerhouse for it, what with the US military building compute clusters out of them and all. quote:Right now, for a CPU to send data and commands to a GPU, that requires a context switch. That is, a thread must be halted and stored, the GPU thread must be read from cache (or worse, RAM) and resumed, and then data must be copied from CPU-addressed RAM (i.e. main system RAM) to the GPU's video RAM. Oh so in a modern PC a GPU still has to go through the Northbridge. It'd be cool if a GPU could send commands to storage to retrieve textures to be sent to its VRAM.

I'm wondering if I'm having this issue with both of my Sapphire HD7850 cards. I have one in my main i5-2500K rig and one in my i3-2120 rig hooked up to my HDTV. After the screen goes black I hear the fans spin up for about a second or two every 10-20 seconds. If I set the monitor to never go into sleep mode it stops but then I have to manually turn off the monitor or my HDTV. Both cards overclock to 1050MHz without issue so I can't complain too much. I just wonder why AMD never released a HD7850 GHz Edition but I guess that would decrease the value of the HD7870.

Sounds like similar thing - I'm more worried about when I come to sell the card, if it ends up being returned. Some guy on MSI forum updated the vid card bios and fixed it, but this one is latest apparently and still does it (diff. model card to theirs). Might be worth seeing if yours has latest bios though? If you ever fix it somehow please let me know. I wonder if I return it if the new card will do same.

I have a GTX570 and I'm trying to run a second monitor to watch Netflix but when I start up my computer with the second plugged in I don't see anything. The first monitor, my main one, is plugged in through HDMI and the second is plugged in through DVI (through a converter to VGA). Does anyone have any idea what I need to do to get this to work?

Try the other DVI-I port, maybe? Sometimes only one has the analog pins hooked up despite looking like both are capable because it saves a tenth of a cent per video card to order DVI-I in bulk instead of both DVI-I and DVI-D ports.

Problem is I can't, because the DVI>VGA converter is too huge and would block the HDMI port. But if that's the solution I guess I'll have to sand it down or something. Also I should clarify I don't get video from either monitor when I plug the second into the DVI port, don't know if that changes anything. Might just be the video card trying to stay in single monitor mode and prioritizing the DVI port over the HDMI.

Might be a bum port. Also, buhhh? What does this converter look like? A DVI-I port only needs a tiny pin adapter for VGA.

Like your normal DVI adapter but the wide parts at the ends that give it that hourglass shape are wider and stylized enough for it to not work with the micro HDMI plug. It's honestly just a bunch of plastic I could sand off.

Apparently there will be no 7xx until after March 2013, the first release being the 780. Radeon 8xxx will be released after Computex in June. Apparently they will bring back the XT suffix for the 8970, they will also make 8930s out of the more crappy 8950 silicon. The two cards will also sport 3GB of memory by default. However, they will finish them before schedule to release them in case Nvidia does something drastic or amazing.

Also, I believe the 8xx from nvidia series will be the first to have its own dedicated mini cpu for talking to the CPU (If I'm not mistaken, this is to make things like context switching easier and do the whole GPGPU thing).

AMD lifted the NDA on the GPU portion of the A10-5800K "Trinity" APU. The NDA is still present on the CPU portion, and AMD isn't saying more on pricing than "about the same as a Core i3," so it's a bit difficult to interpret the results exactly. Nevertheless, that's some really healthy performance from the IGP, far higher than HD 4000. Unless the chip is adopted in volume, it probably won't have much impact on the desktop market, though - it performs a bit under the really-weak GeForce GT 640, suggesting that a Core i3 plus any worthwhile GPU (GT 650+ or HD 7750+will still be a huge performance increase for not a lot more money. Mobile market, now you're talking.

http://www.xbitlabs.com/news/cpu/display/20110119204601_Nvidia_Maxwell_Graphics_Processors_to_Have_Integrated_ARM_General_Purpose_Cores.html This is the first article that came up (there are many more, look up Maxwell architecture), but basically its automating off all the stuff that you have to do on a gpu but with a cpu + some nice things like preemption. I think they are also going to skip a fab step and go smaller, but I'm a bit lazy to look right now. If this pans out the way they say it does, its going to make somthing like 8k UHD resolution viable with crysis <foo> going full blast. More likely it will be a 30 - 50% boost on the first generation, with the "tock" generation right after adding another 20 - 30% on top of normal gains as they figure out what to optimize. If I remember correctly, its currently on track to be something like 8x the power of the current 6xx series, but not out till late 2014-2015. Would be cool to see prototypes on the new consoles, so we all get some awesome graphics for the next xxx years.

It's not really fair to compare a chip due out next month to what will be out in 6+ months. The AMD Trinity chips seem like they'd be good for HTPC usage, and the mobile versions are competitive with the mobile HD4000 in games.

Intel has had demo Haswell chips out for some time now, they're been at a couple of big shows. They're not anywhere near consumer-ready yet, but the chip exists and it works as well as they say it does, so the comparison is quite a bit more valid.

It's not really fair to compare a chip due out next month to what will be out in 6+ months. Trinity and Llano are overkill for strictly HTPC use, and the iGPU is laughably weak for gaming compared to a cheap 7750/7770. It does have a point in laptops, but AMD always have a very limited selection in this segment and it is very possible to find a much more capable SB/IB + discrete GPU laptop at around the same prices. http://www.dailytech.com/IDF+2012+Haswell+GT2GT3+Processors+Run+Skyrim/article27656.htm quote:The GT3 is running "Skyrim" at 1920x1080 resolution with High settings, while the HD 4000 GPU next door is running the same game at the same frame rate, but at Medium settings and a 1366x768 resolution. 2x the pixels + high over medium = more than 2x the performance over HD4000, way beyond Trinity territory. If I was Nvidia even I would be scared if Intel can keep pulling off 50%+ GPU performance every tick or tock. I don't see why it isn't valid to compare Trinity to Haswell. It took AMD 1.5 years to release Trinity after Llano for a minor iGPU increase, which means we are very likely to get stuck with Trinity level AMD performance for the next 1.5 years, too. Haswell will crush it like a bug till then. Palladium fucked around with this message at 07:28 on Sep 28, 2012 |

Sure, but at this point I think it's only reasonable to consider gaming on integrated graphics in laptops, or in a limited fashion on desktops (which for me is the once in a while game on the HTPC). In the mobile space, the Trinity chips that came out in May look competitive overall (generally good GPU, weaker CPU), but as you mention have had a limited impact on the market.

I'm not trying to say that Haswell won't be a significant improvement, Intel has clearly demonstrated that, and I'm sure it'll only get better with driver improvements and such. All I really meant is if someone is looking to purchase something sooner, Trinity can be a valid option in certain use cases/price points while Haswell is too far out.

So apparently MSI was overvolting their GTX 660 Ti and 670 Power Edition cards, which gave them performance gains but also caused some systems to fail to post or get black screens after a change in load. http://www.tomshardware.com/news/MSI-GTX-660-670-overvolting-PowerEdition,18013.html

Jesus, that's insane. I can't believe MSI would pull some poo poo like that. I hope this is a one-time blip rather than something they'll be revisiting in the future, that's like XFX's bean-counter parts harvesting combined with Gigabyte's dangerously out of spec power delivery rolled into one. I guess "gently caress it, just overvolt it like crazy and drat the consequences" is one way to get past the hassle of carefully binning chips for given performance categories. Sticking with EVGA, they've been good to me many times. No obfuscated over-volting and my 680 is both appropriately binned (runs perfectly well in any torture test at stock settings) AND overclocks really well, too. I'll be extremely disappointed if I ever find EVGA's gone off the reservation like that, but I trust them not to. Thing is, I'd have said that about MSI until today.

Athenry posted:Is there any brand that hasn't had some issue like this? ASUS? From what I've read I guess the MSI problem I had on my cards was actually happening on all 570's that used the NVidia reference design. Probably much worse in my case because the card was OC'ed from the factory. Still, poor thought by MSI to release a factory overclocked card that was virtually guaranteed to fail. I eventually just bought an ASUS 570 and have had zero problems since. I'm kinda surprised that there was never a recall or something on those cards though. As far as I know they stopped selling them and some manufacturers started releasing newer edition cards with more VRM's or something that solved the problem but those first gen ones were just awful. Just look at the average reviews: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127552 Edit: Also as for the MSI support. My first card started getting artifacts and crashing in games after a month or two, I RMA'ed it and the replacement had artifacts/crashing right out of the gate. Their support teams told me to overvolt it and even gave me a custom bios set to the higher voltage so I wouldn't have to run software to do so. That actually worked for several months before it started crashing again. The third one I didn't even try, I just gave it away to a co-worker who has since informed me that it too developed the same problem. Not sure if he bothered with the RMA process.
