Battlefield 3 - HD7850, HD 7790, GTX 650 Ti, GTX 650 Ti BOOST

Battlefield 3 (DirectX 11)


 

Battlefield 3™ leaps ahead of its time with the power of Frostbite 2, DICE's new cutting-edge game engine. This state-of-the-art technology is the foundation on which Battlefield 3 is built, delivering enhanced visual quality, a grand sense of scale, massive destruction, dynamic audio and character animation utilizing ANT technology as seen in the latest EA SPORTS™ games.

Frostbite 2 now enables deferred shading, dynamic global illumination and new streaming architecture. Sounds like tech talk? Play the game and experience the difference!

Here is our testing run through the game, for your reference.

Without SLI or CrossFire to worry about in these sets of data, the results from the FRAPS metrics and observed average frame rates are right in sync with each other.  I think you'll find this to be the case throughout all of this set of results. 

A first glance of data comparing the various GPUs shows the GTX 650 Ti BOOST to run just a bit faster than the Radeon HD 7850, while the HD 7790 outpaces the GTX 650 Ti pretty easily.

No big surprises in frame times with the exception of the hitches that are seen in the HD 7790 and (more frequently) on the GTX 650 Ti.

Another view of the performance of these cards shows the "about" the averages in the 50th percentile mark - the GTX 650 Ti BOOST is over 50 FPS with the HD 7850 just below it.  The HD 7790 runs at around 40 FPS average for the entire run and the original GTX 650 Ti hits 36 FPS or so.

The variance levels of the HD 7850 and GTX 650 Ti BOOST are great and only the original GTX 650 Ti seems to be problematic.

These cards kind of struggle on BF3 at 2560x1440 but both the GTX 650 Ti BOOST and the HD 7850 run neck and neck at about 30 FPS.  In this instance the GTX 650 Ti original card is actually FASTER than the HD 7790 as well.

View Full Size

Once again the GTX 650 Ti card has the most variance, even though it is running "faster" than the HD 7790.  Both the HD 7850 and the GTX 650 Ti BOOST have tight collections of frame times and run evenly.

Another view of the same data here as we look at the minimum FPS graph with the poor GTX 650 Ti original bring up the rear...

View Full Size

Both the GTX 650 Ti and the HD 7790 have higher frame time variance and potential stutter rates than the higher performance HD 7850 and GTX 650 Ti BOOST.

I just saw a video from valve discussing a tool called Telemetry from RAD games, it seems like it could be useful for analysis of game performance.

SUGGESTION FOR FRAME VARIANCE GRAPH:

You have already noted elsewhere that Percentile (1-99) is insufficient, for tracking large SPIKES in Frame Times, spikes which may occur only once every few seconds (i.e., once every few hundred frames, thus well beyond the 99th percentile threshold).

So you need a different dependent variable (x-axis), with 'milliseconds' remaining the independent variable (y-axis).

In a 10 minute gampeplay section (36000 Frames at 60 FPS), 36 Frames is equivalent to the 99.9th percentile (36000 divided by 1000).

If you put '36' on the x-axis (or perhaps multiples of 10), you could easily show people the effects of LARGE SPIKES IN FRAME TIMES. In many cases/circumstances, more illuminating than Frame Variance Graphs which show nothing beyond the 99th percentile.

Are there any redeeming features to AMDs Crossfire solution?

April 8, 2013 | 11:06 AM - Posted by Anonymous (not verified)

Yes, they drop every other frame in crossfire and count it anyway and sell it to their fans as a superior frame rate than SLI.

AMS CF Frame numbers sold 80!(actual screen rate 40+stutter ! )

Wow it sure beats 76 from SLI !

Yes, a very "redeeming" quality.

Thank you for not answering my question :)

I just wanted to know if there might be an upside with regards to perhaps input lag. Kind of hard to measure though.

Ok, here's a few thoughts. With the AMD runts and drops, and the fans now trying to claim "less input lag", my question is of course, "What are you aiming at?" !

With every other frame dropped or runted, you're getting ~50% of the game screen opponent positions from the frames displayed (first person shooter as an example of course since most games are that ) - so your opponents position on screen is "jumping" from one frame over to two frames ahead, changing position in a lurch - with that type of inaccuracy of on screen opponents, how is "less lag" going to help when one cannot see half the positions of the opposition, and aiming at those in between spots just is not directly occurring? you have no visual data for those positions, half the positions of your opponent !

You can see how that may present some real issues for the gamer, as far as firing accuracy.
Yes, one could develop a sort of compensation with practice, just like a similar amount of consistent input lag is gotten used to as the mind and muscles acclimate and compensate accordingly.

So, it appears to me missing frames and runts are anything but helpful, and the lag thenno lag, or the lag not running in sync with what appears on screen could be a real problem.

With equalized frame time outputs to screen, the "smoothness" factor certainly helps aiming at opponents and learning to time things correctly.

Are we seeing that crossfire is inherently borked? Or are we seeing that the current drivers are not leveraging the potential of the hardware?

I'm thinking that drivers can be updated.

A note on the fanboy thingy, surely we need both companies to succeed to push one another to create ever faster and more powerful cards. No?

The problem has persisted at least two series of cards, but based on AMD's response, it likely has always existed. AMD had said they never considered frame metering. Instead, they had been focusing on delivering frames as fast as possible.

That to me would say the drivers were not borked per say, they just weren't trying to do anything about it. They weren't even aware of it.

Nvidia has their metering done with special hardware, but AMD believes they can do the same with software, which they probably can, though it may not be as ideal.

Not sure why the 660 is being compared to a 7870. MSRP is over $100 difference. 7850 makes more sense to me but there must be a good reason the 7870 was chosen.

The GTX 660 is the cheaper of the two cards. You must have the GTX 660ti in mind.

The reason is a big fat smooch on the behind of amd and their fanboys.
Keep the raging natives a bit less restless.
You see, only 2 pages of comments, they didn't come in screaming bias while their radeon I don't believe any of this and "if it's true" it doesn't matter heads exploded.

They have all been made absolute idiots, as the years of their stupidity is apparent.

The years of them screeching no one can see over 30 fps anyway is exposed. It doesn't matter what they knew or did not know, they made every excuse and lie and fanboy promo they could over the course of years and now it is absolutely clear they were seeing only half the frames gobbled with screen wretching runts, but still claimed it was beauty incarnate.

They are fools, and we all know it.

It would be nice to see how a pair of gtx 580's fares, as I have these in my setup. Pretty please! *_*

I can't stress enough how amazing this is.

I have one or two questions though:

1. Is the ATI/AMD Dual-GPU cards like the HD7990 have the same "problems" has dual cards in SLi?

I have an HD5970 and I do recognize there are problems as far as stutter is concerned but, I notice, I have a clear visual "feeling" that something is not right in a very few games. Mostly those "heavy" titles like "Metro2033" and the new "Crysis 3".

2. Is the problem something related to the hardware itself, is it drivers or is it a mix of both?

Sorry, I meant "problems has dual cards in Crossfire?"
