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 see ton of sites never touching topics like this only some stupid product launches. Btw I don't think anyone got paid for posting that thing here?
Think again... these chaps, last I understood, that post news get a couple $ an article (rightfully so for their efforts!).

Why the hate against TPU for quoting and linking to a review? There are lots of reviews linked. And there are LOTS OF TERRIBLE NEWS PR POSTINGS. I found the article and benchmark take on the issue interesting and thought provoking. Conclusion... this merits further investigation. There seem to be a lot of peeps here that don't like objective analysis. If the data can be criticised, or the method biased due to looking at just one game, then that can be improved... but the strategy of research is not wrong.

I just checked, and those arguing for a particular side matches what is in their 'system specs'.

A few of you have also spoken against tpu for posting something like this. This is a great topic to make sure that you aren't speaking in a biased tongue before clicking 'post reply'.

That being said, this review should have taken into account more than one game if they are going to go public, as it is unintentionally slandering a company, and is pretty serious in a business sense. While I haven't noticed it on CF 5750s or my 7950, the videos do show that there is a real problem in Skyrim, nothing more, so take it as that. I trust that AMD is looking into this, and if they see it as a serious issue, they will take measures to fix this.

Because the haters are stupid and blinded by fanboyism. As Logan from TS said, fanboys must die. :nutkick:

There is just as much argument against as it is for posting this, that I will agree.

Due to the review not being very comprehensive in its findings, I must say that I disagree with them posting this on TPU, but without them having posted it, I may not have heard it because this is the only tech news site that I go to.

Maybe it would have been better if it were not front page news, but if AMD fixes this issue, then TPU helped fix this problem by perpetuating this news.

Do you think this has more to do with experience in using a card versus fanboyism? I mean hwo could one speak to their experiences if they didnt use the card in question... :slap: :D

Micro-stutter does exist. Period. How much it bothers some people more or less than others is going to differ. I notice it, but it doesn't bother me. Granted the lower frame-rates you get the more you notice it. I'm a little more curious with the settings that they're using as well as the hardware that was used to test it.

You. And anyone else who would use a slap smiley. It is the one smile, along with shadeshu, that I don't use because it is offensive.

"You" what? I didnt ask a who question in the first place...? And notice the big smiley at the end... yeah, that is there to let you know that slap smiley was in fun. Find some hackles kiddo, you shouldnt be getting offended by smilies replying to an off the mark comment.

to all upset about this.....

im sorry but this is true....

i have 2 rigs one with 2x6970 cfx and one with 670 sli......there is a feel of smoothness on the sli setup that is not there with the cfx setup.....both on intel 1155 2700k-amd 3570-nv

and before you start crapping all over me saying SEVEN950 not SIX.....i built my cousins rig just last month using a 7970dcii......similar results.......

You have been on forums long enough to know exactly how many people speak without knowledge of a subject.

And remember, I am not the one that made the spelling mistake.

Riiiiiiiiiiiiiiiiiiiiiiiiight. So with that said, doesnt that make your original comment a bit odd? Who can speak to it more than people that own it, yet your post infers they are biased in their opinion (at least that is how I took it). Totally confused, perhaps we both need some coffee. :roll:


That would be a simple typo, sir. :rolleyes:

Of course, in order to accurately judge the provided information, there should be a listing of the system used.


I love how everyone just jumps into the AMD vs NVidia thing, but none looks to system faults as the cause.....except for AMD themselves, who said they would look into it.


As to why TPU posted this, it's knowledge sharing. We MUST cover both the good and the bad...you gotta have the bad to know what good is...or you only have half the perspective. :p

I do get some noticeable stutters on my single 7970 wether overclocked or not. But this happens once per hour or so and only in selected games. This lead me to believe that it is the card's fault and not AMD's (esp since my flatmate with his 7950 doesnt get any stutters).

The game called Path of Exile has an option to view Frame Latency in addition to FPS and my 7970 has a stable 16-17ms there with some random, rare (every 5-10mins) spikes going to 25-30ms and really rarely having a 50+ms spike which is easily noticeable (Its like the screen slightly "jumps" up and down for a sec). Again, since it is so rare, I think it is my card's issue.

EDIT: I definately NEVER noticed spikes in Skyrim after having played so many hours but I have noticed it in few other titles such as Far Cry 3 (recent example)

Read the original review and I think he weighs it down too much. Again I don't think most people would notice this anyway, and he's basicly telling them the AMD solution sucks right now if you want a smooth gaming experience (which you want) while there are tons of AMD users who say they don't have this issue. To my horror it's posted on Ars Technica as well.

I enjoy reading new video card reviews, especially here at TPU. Interpreting the charts it seems clear that ATI/AMD's current cards pump out raw fps with high/low cap optimizations? and Nvidia's cards are geared specifically for a "smoother" or more "refined" fps experience.

Both methods are distinguishable and people will just prefer one or the other.

HardOCP are speeking about this "smoothness" from Nvidia setup for years now. Mostly when using multiGPU setup, multi monitor being even worse.

From Hardocp testing, you seem to need more FPS to have the same "smoothness feeling" while gaming VS Nvidia. They spoke about it lots of time on lots of reviews.
Yeah, I remember seeing a few articles before that showed this issue with AMD cards. It seems that it's mostly dealing with how fast the cards load up textures and from what I've read, the Radeon cards have always been slower (I've owned Radeon cards myself for years.) I'm actually considering Nvidia cards this time around for this reason (was before the article showed up) but I really liked using ATI Tray Tools.

Curious if monitor interface affects overall latency? Prolly another reason to stick with DVI/DVI-DL :o

well i returned by gtx670 after stutter after stutter in games. This smoothness thing that people keep mentioning is all in the head bcoz i couldn't find it :slap: I will try the amd 7 series and see if that helps with higher frame rates, if not i will return that also and wait for next gen

So to clarify, you returned a GTX 670 because it stuttered apparently, but it didn't really because as you say it's all in your head.

Regardless your now gonna buy an AMD 7 series card because as this thread proves, higher framerates don't automatically mean it's smoother/better.

Good job.

I just hope AMD optimizes its drivers nicely, especially in CFX configuration. Micro-shuttering for me is just meh, not a big deal at all since I have experienced this phenomenon on both AMD and nVIDIA cards.
