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
GeForce GTX 770
33.5 GPixel/s
GeForce GTX 660
19.6 GPixel/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.

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
You might feel that 155 FPS at 2560 x 1600 is a little pointless; however, thanks to the release of new 144Hz 2560 x 1440 monitors, the demand for ultra-high FPS to help offer extra smooth gameplay is becoming greater.

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

The R9 290X’s 55% fan speed “Uber” mode is high enough to prevent GPU throttling in workloads, even under sustained load.

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.
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.

AMD Radeon R9 285 packs 1792 Stream Processors

Recent rumors suggested that the AMD Tonga GPU will be very power efficient or at least better than Tahiti, but we have to wait and see some benchmarks before leaping to any conclusions.
We managed to confirm that the upcoming AMD Radeon R9 285, based on AMD's new Tonga GPU and scheduled to launch sometime this month, will pack 1792 Stream Processors.
The Radeon R9 285 will be price in the $300 US range which means that Tahiti based cards will be receiving a major price cut as hinted previously to make room for the new cards otherwise having both Tahiti XT and Tonga at the same price will mean poor sales for the inferior product of the two.
While Tahiti is generally replaced by its successor Hawaii, it is still a part of the current R9 200 series line as a performance part rather than the high-end product.
