The Radeon R9 280X Review: Feat. Asus & XFX - Meet The Radeon 200 Series
by Ryan Smith on October 8, 2013 12:01 AM ESTSynthetics
As always we’ll also take a quick look at synthetic performance, though as 280X is just another Tahiti card, there shouldn't be any surprises here. These tests are mostly for comparing cards from within a manufacturer, as opposed to directly comparing AMD and NVIDIA cards. We’ll start with a quick look at tessellation performance with TessMark.
If nothing else, TessMark quickly confirms that our 280X is boosting to near its boost clock here, judging from the performance advantage over the 925MHz 7970.
Moving on, we have our 3DMark Vantage texture fillrate test, which does for texels and texture mapping units what the previous test does for ROPs.
3DMark Vantage’s pixel and fillrate tests quickly serve as proxy tests for GPU and memory clockspeeds in this case. Both of which of course put the 280X at very close to the 7970GE in performance.

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.
