The Radeon R9 280X Review: Feat. Asus & XFX - Meet The Radeon 200 Series
by Ryan Smith on October 8, 2013 12:01 AM ESTCompany of Heroes 2
Our second benchmark in our benchmark suite is Relic Games’ Company of Heroes 2, the developer’s World War II Eastern Front themed RTS. For Company of Heroes 2 Relic was kind enough to put together a very strenuous built-in benchmark that was captured from one of the most demanding, snow-bound maps in the game, giving us a great look at CoH2’s performance at its worst. Consequently if a card can do well here then it should have no trouble throughout the rest of the game.
Like Metro this is the first time we’ve deployed this benchmark in a review. The results as it turns out are extremely good for AMD, with the reference clocked 280X surpassing the GTX 770 by over 16%. Given the price disparity between the cards simply tying the GTX 770 would be a good outcome, so surpassing it is even better. Of course this is basically a best case scenario, so not every game will see a lead like this.
On a side note, it’s mildly amusing to see that the 280X delivered 30fps on the dot. For an RTS game that’s a perfectly reasonable average framerate, so the 280X ends up being just fast enough to deliver the necessary performance for 2560 in this game.
Finally, on a lark we threw in the GTX 780 results, primarily to visualize the gap between the GTX 780 and its half-priced competition in preparation for the launch of the 290X. Never did we expect to see a 280X card top the GTX 780, but sure enough that’s what happens here, with the Asus factory overclocked 280X passing the GTX 780 by 0.1fps. This isn’t really a fair comparison due to the factory overclock, but it’s interesting none the less to see a Tahiti card keep up with GTX 780.
CoH2 also gives us a reliable look at minimum framerates, which like the average framerate over the whole benchmark appears to be entirely GPU bound. The 30fps average for the 280X at 2560 may be playable, but players sensitive to dips in the framerate will not appreciate these minimums. To get the minimum framerate about 30fps we have to go all the way down to 1080p at high quality.
Finally, while we didn’t have time to collect FCAT results for every card we were able to collect limited FCAT results for the most important cards. With our delta percentages method we’re looking for sub-3% frame time deltas for single-GPU cards, which is actually something that everyone has trouble with in CoH2. What the minimum frametimes hint at is that this game has a periodic frame time spike to It, that although it won’t be a problem for RTS gameplay, will similarly set off players sensitive to changes in frame times. This appears to be the work of the game and benchmark itself, as all of our cards struggle here in a similar manner.

I still say its rebadge. The NVIDIA G92 went from 65nm to 55nm and lost analog TV out so by your definition G92 is not rebadged.Jumangi - Tuesday, October 8, 2013 - link
Yea that makes these totally different...ninjaquick - Tuesday, October 8, 2013 - link
What core difference exists between the 290X and the 280X? None really. The next gen's 370 is going to be a die-shrunk 280, and the 460 of the gen after that will be the same 7970 again. AMD is not going to bother releasing a new core design until the GCN is no longer apt for the task, which will only occur if HLSL/GLSL are retired completely.Gigaplex - Tuesday, October 8, 2013 - link
TrueAudio, some GPGPU instructions from GCN 1.1 plus whatever the 290X introduces on top of that is basically the core difference between 290X and 280X.Cellar Door - Tuesday, October 8, 2013 - link
I was looking forward to the R9 280X - simply because I hoped it would offer new features, revised silicon, maybe even new iteration of GCN. A REAL step forward - this is a let down. Because this hits my price point as I won't be able to afford their R9 290X, AMD was supposed to be a true champion of price - like always. It seems like I have no choice but to go with the green camp.silverblue - Tuesday, October 8, 2013 - link
Wait a minute... it trails the 770 on average by only a small amount and retails for $100 less. Sure, there's no game bundle, but how is this fleecing anybody?just4U - Tuesday, October 8, 2013 - link
One would think (since it's still pre-order status) that it's done in co-operation with their partners to help get rid of excess stock on the 7x line.. so Never settle bundles won't be offered until after all that is nearly gone. I suspect that such bundles will start being offered on the new line just as the holiday season starts.ltcommanderdata - Tuesday, October 8, 2013 - link
https://twitter.com/ID_AA_Carmack/status/386899206..."9x draw calls is credible over stock D3D, but Nvidia OpenGL extensions can give similar I mprocements."
In regards to Mantle, do you have any comment about John Carmack's report that AMD's claim of Mantle providing 9x more draw calls is already achievable by nVidia using their OpenGL extensions? Console porting is still an unique feature of Mantle, but on the draw call issue, if DirectX is slow to improve on this, then maybe AMD, Intel, and nVidia coming up with cross-vendor OpenGL extensions to address the issue may be a better solution than Mantle, especially given it converges with increased interest in OpenGL with SteamOS.

AMD has made a similar statement. The new OpenGL extensions will bring similar improvements to what they advertise with Mantle, and that in the end the API will not be the bottleneck. As long as it's not Direct3D it seems. :D Perhaps even MS will eventually improve their game sooner or later.ananduser - Tuesday, October 8, 2013 - link
Have you not read Ryan's hunches on Mantle? Mantle is, or derived from, MS' low level Xbox API.
