HD 7950 May Give Higher Framerates, but GTX 660 Ti Still Smoother: Report
The TechReport, which adds latency-based testing in its VGA reviews, concluded in a recent retrospective review taking into account recent driver advancements, that Radeon HD 7950, despite yielding higher frame-rates than GeForce GTX 660 Ti, has higher latencies (time it takes to beam generated frames onto the display), resulting in micro-stutter. In response to the comments-drama that ensued, its reviewer did a side-by-side recording of a scene from "TESV: Skyrim" as rendered by the two graphics cards, and slowed them down with high-speed recording, at 120 FPS, and 240 FPS. In slow-motion, micro-stuttering on the Radeon HD 7950 is more apparent than on the GeForce GTX 660 Ti.Find the slow-motion captures after the break.

I mean the end of the world is upon us and this is all you can think to argue about, priorities people!!! :laugh:
OT
I couldn't be any happier with the performance of my 7950 coming from a 570 and don't notice any microstuttering in any of my games, not saying it's not there I just think it's probably a moot point to 90% of people, the other 10% of people are probably those who claim they can see and perform better in games running at over 120FPS :rolleyes:
I wouldn't actually be surprised if TTR just randomly made up the graphs at this point because of how they insist on doing the same articles to make nvidia look better at this point and using data that not only is selected based on favoritism but also inconsistent with other sites, they only hide behind their testing method at this point.
First it was the original 660ti review where they included TWIMTBP games where AMD suffered in the final conclusion but removed gaming evolved titles where nvidia suffered. Then the update which they hid behind windows 8 drivers and a selection of games that were different, Removing BF3 and other AMD favored titles and adding a few of TWIMTBP titles. The conclusion was stupid and the testing was stupid so when they were called out, The made the follow up review which at this point I am not even inclined to believe the numbers.
The whole year of review from the tech report has been praising nvidia. Thats not so bad but when they often skew the price of AMD and nvidia cards in the conclusion and not including AMD favored results. It starts to be something.
I'd put it down to drivers. Fixable. And it's not an issue to me so I'm happy.
But it is a bit shameful the ferocity of the arguments in this thread.
7950 vs 7950 boost does the clock speed fluctuations cause the problem to be more pronounced
how bad is the issue on say the 7970 and 7970 GHz edition does clock speed on the GPU lower overall latency giving higher clocked cards any kind of benefit or does it further cause problems
does the 7870 experience the same issues
Its an interesting glimpse but 1 GPU 1 Driver revision is not enought to say theres a huge problem here. more data would be appreciated in this case to get a clearer view. first i didnt say TR did im saying essentially i want more testing done before saying somethings wrong drivers / auto boost clocks going up and down etc can all have an impact on stuttering 7970 stock vs 7970 ghz edition and 7950 stock would be welcome tests on the same driver to see if boost clocks are causing some issues. Seems your taking my post and trying to paint it in a light that makes your post more meaningful, i simply want more testing done nothing more, Altho why people are up in arms over skyrim surprises me AMD has had issues with the Gamebryo engine for hell 9-10 years now Morrowind / Oblivion / Fallout 3 / Fallout New Vegas / Skyrim all exhibit this issue. an easy way to fix it is 1 mod the game a great deal and 2 lock it to 59Hz. That said stuttering can be issue ive seen it many times. not saying TR is wrong but what im saying is their can be easy solutions that fix the problem.
I do have to say this brings back memories of my 4870x2 and the stuttering in Oblivion due to crossfire.
Micro-stutter being one, but what are your guys experiences with shadow flickering? I have a HD7850 and as there is movement in a scene (i.e. camera panning) the shadows are a mess! I get this in every game I play. Another issue - corrupted frames. Every now and then a frame is fucked up, like there are solid, black triangles, untextured objects etc. I mean it happens from time to time and at first I thought "oooh, its just nothing". Now the longer I'm being exposed to it the more irritating it is.
The problem is these issues are small at first, but after you've seen something once it begins to bother you more and more with time. And I really don't care if its software or hardware - what matters is the user experience. Next time I'll give nVidia a try.
in case you have already used 12.11 beta driver then you should submit your problem here instead posting off topic here that's your own choice whether you'll gear up your rig with radeon or nvidia, end of story
I'm using the latest WHQL driver, which is 12.10, so I won't post here :shadedshu
or idk i guess i just dont understand this whole latency thing, it just sounds fishy to me that more frames are taking longer times in between to display
another thing would be the mechanism in which the frames are transmitted, its clear on the amd the frame overlaps the other, where for nvidia maybe each frame fades while the other displays?
im very ignorant on this matter. but can anyone clarify?
If someone wants to give me a 680 I can do a comparison :roll:
yes i get your point but that is when for example an intensive scene comes up and it stutters for a bit or in some cases fps takes a dip thats why some reviews have min fps in their graphs, but i didnt notice that in the videos here, its just consistent frame by frame change is what i notice
Since Radeon 7000, and now HD7000... I didn't find that trouble, in my opinion we are just too lazy to do some tweak and wait the new fix, and I believe everybody on this forum can do it.
I thought it was because my CPU was doing something, and since I couldn't pinpoint what it was exactly, I would just restart and not see the problem again for a very long time. This has happened maybe a half dozen times in the last five years.
I just now thought of this after looking at the video again. The first time I remember it happening was on the 9800GX2, then on a 4870.
After reading the review amd all the comments (both on TPU and techreport), I had the preconception that 660ti is stutter-free.
Well, i watched the videos (both 120hz and 240hz videos) and i ended up with the conclusion (as i said, thinking that 660ti has more "magic" to it and no stuttering) that both GPUs stutter like hell, of course, the effect was amplified by recording the game at 240hz, where the actual frame rate was ~80fps, so the choppiness.
In the areas where 7950 stutter, like where you start going up the small hil after you pass that road (i think), but also the 660ti stutter, just as an example.
Unfortunatelly, video cards have stuttering, and Skyrim is a bad example to exhibit, cause Skyrim is poorly optimize, remember SkyBoost.
We should see more games tested, maybe TPU will conduct a test like this.
