they might be trying for a "Hail Mary pass" (suicide run, whatever you wanna call it) and looking for a simultaneous fabrication process shrink and a new architecture in one release
doing that is exceedingly risky, which is why Intel only does one of the two for any given release
but if they execute it successfully and on-time, it'll be huge
I have the single-GPU equivalent of the 7990 and it suits me fine; I also paid only a small amount less for my 7970 than people are paying for the 7990 now... but I've been using and enjoying my 7970 since the first week it was released
@BenBrocka For certain workloads, the shift from the VLIW5 architecture to GCN will be huge. For 3D gaming itself (not including capture/encoding), it's probably about 25-40% increase in FPS, or maintaining the same FPS with 25-40% more detail/complexity.
the workloads that benefit the most from the VLIW5 -> GCN shift are, for example, floating point arithmetic on very large arrays.... but games don't use floating point all that much, and the latency required to complete processing on some of those instructions is too high for a 60 FPS game
what I'm trying to say is: Tessellation, GPU video encoding (using the VCE in GCN), and OpenCL floating point workloads will see tremendous improvements with GCN. Other stuff, about what you'd expect.
@BenBrocka depends on the software... if the software uses the VCE (which is special fixed-function hardware for encoding), then yes... otherwise, if it uses OpenCL, it'll still be faster... but if it just uses DX9/GL2 shaders for encoding-assist, or is pure software encoding, then no.
I believe Sony Vegas as of now uses OpenCL but not VCE, so that app in particular would run faster on the 7970 but wouldn't blow your socks off... most encoder apps these days are still software based though :(
ArcSoft has some stuff that uses VCE, I don't know if anyone else does
Sony Vegas makes pretty good utilization of my 7970... I watch it in Catalyst Control Center
it does a ton of disk I/O and moving stuff around in RAM for about 30 seconds, then it shoves a scary amount of data down the PCI-E pipe to the GPU, and the GPU's utilization cranks up to about 90% for 3-5 seconds, then more I/O, then another 30 seconds, repeat
when the GPU's being used though, it gets hammered... and I'm sure that helps with encoding time
I guess if you had more disk throughput than I do, it'd go even faster and the GPU could stay pegged for longer periods
probably most of the transcoding time spent in Sony Vegas is reading out that enormous file that FRAPS produces. like 30 GB for a couple minutes of 1920x1080@60fps
that's why the GPU goes idle for 30 second periods
@BenBrocka if you use FRAPS too, my intuition is that your workload for GPU encoding is probably so ridiculously disk-bound (due to the sheer volume of data from FRAPS) that the GPU upgrade wouldn't save you a whole lot of encoding time.
if it takes my 7970 3-5 seconds to encode a "chunk" of video data, it'd take your HD6950 6-9 seconds or so, I figure. Even if it took 15 seconds.... you're still spending 90% of the time just waiting on the disk
@BenBrocka oh, awesome! :) I still don't have an SSD mixed into my desktop/GPU encoding workflow. :( I just have a hardware RAID array of HDDs.
I wish I had a lot of money so I could build The Ultimate GPU Encoding Box
right now with available hardware it'd be: quad GTX TITANs, Sandy-EX motherboard, quad Xeon E5-4650, 256GB FB DDR3 ECC, an Adaptec 7-series 8-port SAS RAID controller, and 4 x SLC enterprise SSDs in RAID-0
Step 1: Play an AAA game from the past 5 years Step 2: Alt-tab and open Youtube and play a flash video Step 3: tab back into your game Step 4: Notice horrid performance Step 5: Alt-tab and look at AMD Overdrive control panel Step 6: Notice your GPU is clocked at 2D clock speeds and FUUUUUUUUUUUU
all Radeon based GPUs since about HD5000 and later come with a feature / misfeature called PowerPlay, which detects what clock rate the GPU needs to be set at based on the current workload, to minimize power consumption and heat dissipation.
Speaking of AMD overdrive, has anyone tried their CPU overdrive? When I OC via my mobo it works fine, same clock speed bost via AMD Overdrive disables areo
every GPU of those aforementioned generations can run at "Idle" speed, "Slow 2D", "Demanding 2D", or "High Performance" (the category names are made up by me)
unfortunately there's a fatal flaw in the driver that handles PowerPlay: if the GPU is currently performing Video Decoding, then it unconditionally, no matter what the load is, sets the clock rate to the "Demanding 2D" rate, which is hard-coded into the VBIOS
@Bob must be a laptop-specific thing. I have no such checkbox.
I have done a lot of research on PowerPlay. I believe the only way to prevent your GPU from clocking down when video decoding is occurring is to (a) don't do video decoding at all (you can disable it in Flash, but then your CPU usage goes up); or, (b) hack your VBIOS to force the lower power profiles to use the high performance clock speed.
It takes a lot of energy (and patience, and forethought) to abstract away from the particulars of individual peoples' problems at particular points in spacetime and come up with generally-useful processes that help people to solve their own problems
I'm not liking how the review audit is picking out questions with a dozen comments and asking if it's too localized. Long comment threads (IMO :P moar meta talk) are a good sign of too localized...
Think of it this way: 99% of SU questions are the equivalent / analogue of Wikipedia's "Talk" pages. 1% of SU questions are the equivalent of a Wikipedia article (in good standing, etc). Those 1% may have wording such that the Search is completely useless in finding them, so unless they are prominently listed somewhere, how will people know to link to them? — allquixotic1 min ago
Joel's recently blogged regarding wikifying question on several recurring topics where users keep asking new versions of the same problem.

@Bob well more commonly it's something like a flickering laser attack, where half is visible on any given frame. And so on screen it's two lasers, on recording you get only one laser. Which is bad.
@OliverSalzburg Your patient and eloquent explanation really helped me. I actually learned from it. Thanks! I think going forward that having more questions like the three you linked to above would be enormously helpful, but even more importantly, we need ways to make these questions quite clearly stand out from the rest. Maybe a Canonical Questions tab along the top? — allquixotic11 mins ago
I have two HDDs (5900 RPM) in RAID 1 (mirror). I know, I know, it's painfully slow. I'm currently in the process of replacing them with faster drives, hence this question while I'm testing things.
For some reason, disabling write-back caching in the Intel RST options gives me much faster write s...
@Leathe Thanks for suggesting Encoder. It seems to have the profile I was looking for (which is quite lucky, since it still doesn't expose some of the more advanced options i would have needed to create one myself).
I'm looking for fast and cheap hosting at the moment and I don't want to rely on users opinions only (many if not most of them are sponsored / the companies themselves anyway)
What's the best way of benchmarking websites on different hostings? Let's say I have 100 addresses from each:

Hello I have a computer using Virtual Box, and I would like as much Windows 7 instance as possible. I'll maybe buy a computer for this, on which hardware should I focus, RAM ? CPU ?
@OliverSalzburg Thank you very much Do you think this is also valid for the processor, that means I'll need a 32GHZ cpu ?(haha). Or maybe a virtualized version take less ghz ?
@Meds you don't dedicate CPUs to VMs, or GHz... it just uses whatever's available as needed; it's dynamic. as you notice, when an OS is idle, it uses very little CPU. but if you need all the VMs doing as much work as possible then yes you would probably want more CPUs
I know this thread is very old however I thought I would post here in case anyone stumbles across it. The windows command line now provides the compact command which, as far as I can tell, is native to windows. That should meet the requirements requested unless I missed something.
Jingle is an extension to the Extensible Messaging and Presence Protocol (XMPP) which adds peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications. It was designed by Google and the XMPP Standards Foundation. The multimedia streams are delivered using the Real-time Transport Protocol (RTP). If needed, NAT traversal is assisted using Interactive Connectivity Establishment (ICE).
, the proposed Jingle specification has not yet been approved by the XMPP Standards Foundation, but is now a Draft Standard,...
@Leathe Those are ReSharper errors. Like missing comments, unresolved references... it's a new C# project I just started where I just dumped some code in from other projects
Right now I'm documenting an octree implementation I grabbed from the GitHubs
Documenting other peoples code is obviously the most fun to have on a Friday evening
Time Cube is a website created by Gene Ray, also known as Otis E. Ray, in 1997 John C. Dvorak wrote in PC Magazine that "Metasites that track crackpot sites often say this is the number one nutty site."
Concept
The website is mostly text written in centered, multi-colored 30-point type in a single vertical column. The following quotation from the TimeCube.com website illustrates a recurring theme from Gene Ray's ideas:
Ray has wagered $10,000 that his theories cannot be proven wrong. John C. Dvorak of PC Magazine characterized the site's content as "endless blather".

@Hennes There's a chance, yeah. But there was zero evaluation of security on this project, but I'll remember it for the future. Probably we'll be taught about this kind of thing next year.
So! Uhm, I just "reinstalled" (ya know, it reinstalls but keeps all of your stuff still) Windows 8 Pro, and now it has forgotten the symlinks I'd made to map user folders to my hard drive (D:).
Since last time, I was told I had done it wrong because Folder History wasn't working (not finding things), I'd like to be told how to do it right this time.
C:\Users\Me <- D:\Users\Me. Also, a few larger pieces of software (like bigger games) from D:\Programs to C:\Program Files or Program Files (x86).
Also there was this minor issue where my whole computer or just Explorer would occasionally freeze up for a few seconds as I heard a little increasingly high-pitched sound coming from the tower (which I think is the hard drive starting)... but maybe it's unavoidable when everything is not on the install drive.
Oh I am so dumb.
http://superuser.com/questions/545672/windows-file-history-is-unable-to-analyse-user-library-modifications I had completely forgotten about this. I'll read it again, try it, and maybe I can finally accept it as the answer, now. :p
