Features Key features of the Radeon R9 280

pixel rate Number of pixels a graphics card can render to the screen every second

Radeon R9 280
26.5 GPixel/s
GeForce GTX 770
33.5 GPixel/s
GeForce GTX 660
19.6 GPixel/s
The Curacao Pro ended up faster than the Radeon HD 7870 in a previous performance overview so its easy to say that the Curacao XT based R9 270X would be much faster and trade blows with the Radeon HD 7950.

texture rate Speed at which a graphics card can perform texture mapping

Radeon R9 280
92.6 GTexel/s
GeForce GTX 770
134 GTexel/s
Radeon HD 7970
118.4 GTexel/s
The GPU has a performance score of around 4000 marks in Firestrike in performance mode and would be available in 2 GB models for $139 US at launch.

floating point performance How fast the gpu can crunch numbers

Radeon R9 280
2,964 GFLOPS
GeForce GTX 660
1,882 GFLOPS
Radeon HD 7970
3,789 GFLOPS
The R9 290X’s 55% fan speed “Uber” mode is high enough to prevent GPU throttling in workloads, even under sustained load.

In The News From around the web

Crysis 3 continues to hurt our graphics cards; we really should put out an informercial about it... At 1080p and the Very High quality settings, the R9 280 is able to push just under 30 FPS on average, 6-7% slower than the R9 280X and 22% faster than the R9 270X.
The last of our DX9 benchmarks (clinging by its fingernails) again proves that the R9 280 from MSI is nearly on par with the performance of the R9 280X reference speeds and is faster than the R9 270X and GTX 760.

The R9 280 versus the GTX 760 in a photo finish

With a bit of work that can be increased, [H]'s testing was also done at 1095MHz with the RAM raised to 5.4GHz which was enough to take it's performance just beyond the stock GTX 760 it was pitted against.
Priced at roughly $260 we have the MSI R9 280 GAMING OC video card, which features pre-overclocked performance, MSI's Twin Frozr IV cooling system, and highest end components.
Bald Eagle products “incorporate HSA features, enabling applications to distribute workloads to run on the best compute element—e.g., CPU, GPU, or a specialized accelerator such as video decode—for up to 44 percent more 3D graphics performance and up to 46 percent more compute performance than comparable Intel Haswell Core-i CPUs,” said the company.
Heterogeneous System Architecture (HSA): The 2nd generation AMD Embedded R-series APU is the first embedded processor to incorporate HSA features, enabling applications to distribute workloads to run on the best compute element — e.g., CPU, GPU or a specialized accelerator such as video decode — for up to 44 percent more 3-D graphics performance and up to 46 percent more compute performance than comparable Intel Haswell Core-i CPUs.

Now that product is available and at suggested pricing, these prices will remain stable.
Scott wrote up a story detailing this latest incarnation of the promotion and he and I both agree that while free is always good great, the age of most of the titles in the program is a bit of a problem.
