AMD Radeon HD 7990 6GB Review - Malta Gets Frame Rated

Sleeping Dogs

Sleeping Dogs (DirectX 11)


 

Welcome to Hong Kong, a vibrant neon city teeming with life, whose exotic locations and busy streets hide one of the most powerful and dangerous criminal organizations in the world: the Triads. In this open world game, you play the role of Wei Shen, an undercover cop trying to take down the Triads from the inside out. You'll have to prove yourself worthy as you fight your way up the organization, taking part in brutal criminal activities without blowing your cover. Torn between your loyalty to the badge and a criminal code of honor, you will risk everything as the lines between truth, loyalty and justice become permanently blurred

In our first graph, both the HD 7970s and the HD 7990 appear to have significant advantages over of the GTX 690 and the GTX Titan even at 1920x1080 with Sleeping Dogs, but our observed frame rates tell a different story - one of runt frames and mis-reported frame rates.

Wow, clearly something is amiss here!  The black and orange lines, if you can call them that, are heavily alternating between short and long frame times while both the GTX 690 and Titan are running tighter, more consistent numbers.

As a result, the average frame rates over the entire run show the GTX 690 to be the best option, pulling about 78 FPS with the Titan at 60 FPS.

You can see in our frame variance data how all of those runts look from a different angle.  The Radeon HD 7990 adds as much as 10 ms of variance to frames while the the GTX 690 barely crosses the 2 ms mark.

The same kind of pattern is seen at 2560x1440, with the HD 7990 and the HD 7970s in CrossFire dropping once we remove the runt frames from the picture.

The bands of the HD 7990 and HD 7970s in CrossFire frame times are actually even worse at this resolution yet the NVIDIA GeForce options are able to maintain very thin lines of times. 

View Full Size

As a result, the average frame rate (seen at the 50th percentile or so) is much higher with the GTX 690 than the HD 7970s in CrossFire and HD 7990.

Clearly the amount of back and forth seen in the frames displayed on the screen with the two CrossFire solutions are producing a less fluid animation and thus we can't recommend them to players of Sleeping Dogs.

 

Sorry, one last time - no solid results from the HD 7990 in our 5760x1080 testing due to alternating dropped frames from the Eyefinity + CrossFire combination so we'll move on to some more tests and closing thoughts.

Ryan, thank you.

AMD must be sado masochistic handing you one of these cards which does show positive signs that they may want to actually fix this.

I am excited for this. I'm not going to buy it but if AMD can improve their Xfire performance next time I upgrade it will definitely be AMD.

Hello
Thank you very much, Mr. Ryan I've been following your site and all of your articles for quite some time
And I'm very interested in the modern way to test the Graphics Accelerator
I need your consultation in some of the things in this regard
Hopes provide me with your Email
Thank you very much again
 And continued the wonderful effort

Thanks Mr. Shrout and team,

I hope AMD can give our memories of ATi new life, and you people are, in large part, that motivation. AMD could not buy a better format to motivate its people, which brings a little excitement to see how AMD will strive to win and make the community a better place.

I've read another review (on tom's hardware) about 7990's performance, FCAT, prototype driver, etc, basically the same thing, although there was something i noticed.
In their benchmarks the hardware (FRAPS) FPS was also quite bigger for the prototype d. compared to the basic catalyst 7990. While for the observable FPS this difference is easy understandable, i found no explanation for the extra FPS.
Prototype driver just "arranges" the frames in a smoother way, but why it appears to produce more frames?

I am running this card with 6 monitors- 5790x2160 in games and getting high smooth frame rates. I have one of those mythical MST hubs (bought from the UK) and it works perfectly.

To each his own. BTW I sold my TITAN since Nvidia can never (their words) support more than 4 monitors. It was a nice card though. The 7990 is faster though (as it should be with 2 GPU's.)

Seems these fan boy threads always devolve to AMD or Nvidia bashing.

Just installed the 7990 last night and went straight to BF3...frame rates SUCKED!! I had a GTX 570 and it's rates were WAY faster. How do I resolve this problem? How do I get the card to work as expected? How do I get good frame rates with this card? What am I doing wrong. I want to run BF3 on ULTRA settings and enjoy all the "eye-candy" that comes with a high-end card like the 7990. PLEASE HELP!!
