AMD TrueAudio technology enhances audio realism by simulating the human brain’s perception of real-world sound, working in concert with the user’s existing audio hardware to recreate a lifelike experience in upcoming games like “THIEF™” by Square Enix or “Lichdom” by Xaviant Games.

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
Radeon R9 270X
35.2 GPixel/s
GeForce GTX 770
33.5 GPixel/s
Unfortunately, you can see we still fall short of that 60 FPS average; although, the 58 FPS average is indeed impressive.

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
At the highest resolution, we do see the card fall just short of that 60 FPS average, but considering our minimum is 48 FPS, we'd say the overall playability of the game is great.

floating point performance How fast the gpu can crunch numbers

Radeon R9 280
2,964 GFLOPS
Radeon HD 7970
3,789 GFLOPS
GeForce GTX 760
2,258 GFLOPS
Another feature is the the updated instruction set which introduces 16-bit floating point and integer instructions that help in low power compute (GPU) and media processing.

shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading

1,792
Despite these few leaked pictures, we still do not have precise specifications for the upcoming R9 285 graphics card as it is still not clear if it will have 1792 or 2048 Stream Processors.

texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes

Radeon R9 280

The Radeon R9 280X is based on the 28nm Tahiti die featuring 2048 Stream processors, 128 Texture mapping units and 32 Raster Operators.

compute units Discrete cores within the GPU

From the block diagram previously posted, we got to know that the Tonga GPU houses eight ACE (Asynchronous Compute Units) compared to just two on Tahiti and each shader engine has its own geometry processor and a rasterizer unit which houses 8 Compute Units per block.

In The News From around the web

At the highest resolution, we see our R9 280 3GB CrossFire setup is able to offer a fantastic 56 FPS average.
Looking at the base clock of the card, the out of the box overclocks, and the bundle that PowerColor has put together, we'd say that this is a pretty strong offering.
At the end of it all, though, if you're looking at something around the low $200 mark from AMD, this is a great option, especially this GIGABYTE version with its strong overclock and fantastic cooling setup.
The overall balance when it comes to performance is quite strong now thanks to the overclock that GIGABYTE has offered.
