I find this quite interesting.

This last metric measures "badness"—that is, time spent working on really high-latency frames. Here, the Radeon HD 7970's smaller spikes at those trouble points in the test run give it the edge. AMD's drivers and GPU combine to produce a smoother gaming experience in this case.

Not too many surprises here. The 99th percentile results are all under 33 ms, which means except for the last 1% of frames, all of the GPUs are slinging frames at better than 30 FPS. Even the longest frame times aren't too large: no frame takes more than 50 milliseconds to render, so there's very little "badness" going on.
Even so, there's a clear hierarchy of performance, and the GTX 780 nestles in just below the Titan, ahead of the 7970 and GTX 680.

These results are boring, but in a good way. The FPS average and 99th percentile frame times tend to agree, which means we aren't looking at any major problems with high frame latencies. A look at the distributions from each card will confirm that assessment. What's left is a very straightforward outcome: the GTX 780 is somewhat slower than the Titan but faster than the Radeon HD 7970. See a pattern developing yet?

Wow, so this outcome is more complicated than I thought. What's happening here is evident in the plots above, if you look closely. Although there are some frame time spikes for all of the cards, only the Titan and GTX 780 show substantial spikes in their FCAT results as well as in Fraps. The GTX 680 and 7970 have very smooth lines in FCAT; the hiccups in Fraps are buffered out. As you sort through the various results, you're see the different cards changing position depending on whether we're looking at Fraps or FCAT data and what's being emphasized.
We could get off into the weeds discussing which latency spikes matter more, but we need to be careful. We have powerful tools now that can measure performance very precisely, but we don't want to overemphasize minor differences. In this case, all of the cards perform quite well, and the differences between them are imperceptible, as a look at the videos we captured with FCAT confirms.

The Radeon HD 7970 pulls off the upset here in our latency-focused performance metrics, followed closely by the Titan and the GTX 780.

Look at the GTX 680 in Crysis 3, Tomb Raider and Sleeping Dogs, its not good is it? While the 7970 holds good smoothness in all games.

^^ best review site out there.

Gregster · 23 May 2013 at 15:53

Both interesting reads and looking at both those sites, it looks like the 7970GE does very well in single card games but looking at Crossfire is a worry.

Those crossfire frame times are shocking.

I don't get anything like that so...

Me neither

humbug · 23 May 2013 at 16:06

Supposedly there is a driver on the way to fix that ^^^

Edit, it would be interesting to run those CF tests ourselves to see how our results match up with pcper

Locky · 23 May 2013 at 16:07

I'm going to put my neck out and say their testing is very broken.

Yer, AMD hoped to have it ready in July was the official response. 2 months isn't long to wait to fix what Locky doesn't get

Minstadave · 23 May 2013 at 16:09

a lot of money for a pretty meagre speed bump.

Yep I can't say and pacing up and down waiting for this driver to fix my game play, cus for me there is nothing to fix

You, Matt and Rusty have CF. replicate the test.

you need to go back and read the original article on FCAT to see how it's working - it records each frame from the output of the graphics card and analyses it for frames that haven't been drawn correctly

whether or not you can perceive these is a personal thing - some people say they have no problems with crossfire, others say that they get a general sense of a lack of smoothness with it

FRAPS just takes a figure that the graphics card is reporting, so if the GPU says it drew a frame, FRAPS takes its word for it, where as FCAT checks the output to see if the frame gets drawn or not

Add my review please

I am susceptible to smooth game play, as I say Ive not noticed it tbh, but I admit I have been using fraps to give frame time results and never used FCAT.

I will need to read up on it, is it something I can use to test?

Very impressed with the Vortez review. Nice work whoever put that together.

fantasticCG · 23 May 2013 at 16:20

Gregster I can ask what these time graphs, represent/mean ? Please

apart from they have the 680 faster than a 7970 in valley benchmark which we all know that isn't true.

edit and pretty much every single other benchmark.

humbug · 23 May 2013 at 16:24

where can I find FCAT? I want to have a play with it.

Admiral Huddy · 23 May 2013 at 16:25

Impressive looking results but an expensive card which only benefits 2560+ resolutions. Seems to resolve a problem that doesn't exist.
