Battlefield 4

Our latest addition to our benchmark suite and our current major multiplayer action game of our benchmark suite is Battlefield 4, DICE’s 2013 multiplayer military shooter. After a rocky start, Battlefield 4 has finally reached a point where it’s stable enough for benchmark use, giving us the ability to profile one of the most popular and strenuous shooters out there. As these benchmarks are from single player mode, based on our experiences our rule of thumb here is that multiplayer framerates will dip to half our single player framerates, which means a card needs to be able to average at least 60fps if it’s to be able to hold up in multiplayer.

Battlefield 4 - 2560x1440 - Ultra Quality

Battlefield 4 - 1920x1080 - Ultra Quality

Battlefield 4 - 1920x1080 - High Quality

Our first Mantle-enabled game, Battlefield 4 shows the current Mantle R9 285 performance regressions front and center. At every resolution the R9 285 loses performance, sometimes remarkably so. As a result it is limited to Direct3D.

Regressions aside, I feel like Battlefield 4 is a good case for why the R9 285 needs more VRAM, or at the very least it’s not a good choice for 2560x1440. The sustained performance at 2560 is too low for this game, and the performance loss compared to the 3GB R9 280 appears to be a direct result of VRAM pressure. If the R9 285 had more VRAM, I suspect it would reach parity with the R9 280, especially given what happens at 1080p with High settings.

In any case, this is also the first game where the R9 285 trades blows with the GTX 760 rather than taking a distinct lead. With both cards limited to Direct3D, both cards are also returning similar performance. Which for R9 285 and its higher price tag is essentially a loss.

    All in all, this doesn't really change the market all that much.

    I still very firmly feel that the R9 290 right now (Q3 2014) remains the best price:performance of the mid to high end cards. That and the 4GB VRAM which may make it more future proof.

    What really is interesting at this point is what AMD has to respond on Nvidia's Maxwell.

    I Agree - Tonga is not bad, but on the other hand it does not change anything substantially compared to Tahiti. This would have been a nice result 1 - 1.5 years after the introduction of Tahiti. But that's almost been 3 years ago! The last time a GPU company showed no real progress after 3 years they went out of business shortly afterwards...

    And seing how AMD brags to beat GTX760 almost makes cry. That's the double cut-down version of a 2.5 years old chip which is significantly smaller than Tonga! This is only a comparison because nVidia kept this card at a far too high price because there was no competitive pressure from AMD.

    If this is all they have their next generation will get stomped by Maxwell.

    So all you got from this review is that Tonga is a cut down version of Tahiti? After reading this review, this is the impression you were left with? Reply

    Nope. But in the end the result performs just the same at even almost the same power consumption. Sure, there are some new features.. but so far and I expect for the foreseeable future they don't matter. Reply

    This is the first mid-range card to have all the value add features of the high-end cards. I wish AMD would leverage TrueAudio better, but the other features and the nice TDP drop.

    The color compression enhancement is a very interesting feature. I think that in itself deserves a little applause because of its significance in the design and comparing to the 280's. I think this is more significant, not as a performance feature, but similar to what Maxwell represented for NV in terms of efficiency. Both are respectable design improvements, in different areas. It's a shame they don't cross-license... seems like such as waste.

    Well, the TDP-drop is real, but mostly saves virtual power. By this I mean that 280 / 7950 never come close to using 250 W, and hence the savings from Tonga are far less than the TDP difference makes it seem. The average between different articles seems to be ~20 W saving at the wall and establishes about a power-efficiency parity with cards like GTX670.

    The color compression could be Tongas best feature. But I still wonder: if Pitcairn on 270X comes so close to 285 and 280 performance with 256 bit memory bus and without color compression.. how much does it really matter (for 285)? To me it seems that Tahiti most often didn't need that large bus rather than color compression working wonders for Tonga. Besides, GTX770 and GTX680 also hold up fine at that performance level with a 256 bit bus.

    The TDP drop is something I did not think about being a paper launch value. You make a good point about the color compression too. It will be interesting how both fair. That may be an interesting topic to follow up during the driver refresh.

    As an owner of GTX 260 with a 448-bit bus, I can tell you that with anti-aliasing, it matters quite a bit as that becomes the limiter. The shader count is definitely not the limiter usually in the low-end and mid-range displays that these cards will typically be paired with. My GTX 260 and 1280x1024 monitor kind of illustrate that with 216 Shaders/896MB. :-)

    It isn't pretty, but I don't see anything that forces me to upgrade yet. Think I've got two more generations or so to wait on before performance is significant enough, or a groundbreaking feature would do it. I'm actually considering upgrading out of boredom and interest in gimmicky features more than anything else at this point.

    GTX 260 is like 6 years old now. It's lacking DX11, having less than 1 GB of (relatively slow) GDDR3 VRAM, and overall should be 3-4 times slower than R9 285 or R9 290, I guess.

    I really didn't think anybody still uses these old gen cards (e.g. I have HD 7950 Boost Dual-X which is essentially identical to R9 280).

    Because they would loose money! LOL. And they are both about the same anyway, Except AMD goes for brute force to get performance,(like using aV8) And Nvidia uses efficency with power. (Like a turbo charged 4cyl or 6cyl) Reply

    You are being pretty silly here. Both AMD and Nvidia were rebranding a lot of cards these last few gens. You can'y go after AMD for rebranding a 2-3 year old chip, and then say its fine if nvidia does it and blame AMD's 'lack of competitive pressure'. If lack of competitive pressure was the reason for rebranding, then there was lack of competitive pressure on both sides.

    And I highly doubt the 285 is 'all amd has'. this was just a small update to their product line, to bring some missing features (freesync, true audio etc...), and reduced power consumption to the 28x series. I'm sure there is a 3xx series coming down the road (or whatever they will call it). Both AMD and nvidia have been working been squeezing all they can out of older architecture for the past few years, you can't really put the blame on one of the other without being hypocritical.
