by hassan-mujtaba (Oct, 2013)The memory for the overclocked models would be configured at 1600 MHz which is 6.4 GHz effective, pumping out 307.2 FB/s compared to the reference 288 GB/s..
by Jeremy-Hellstrom (Oct, 2013)GPU Tweak- Easy overclocking and online streaming The included ASUS GPU Tweak utility enables R9 280X, R9 270X, R7 260X, R7 250, and R7 240 users intuitive control over GPU and video-memory clock speeds and voltages, cooling-fan speeds and power-consumption thresholds – so they can overclock easily with confidence.
Features Key features of the Radeon R9 280
pixel rate Number of pixels a graphics card can render to the screen every second
by Ryan-Shrout (Oct, 2013)Our benchmarks here today will likely help determine if NVIDIA is as far behind the performance per dollar curve as we think they might be.
texture rate Speed at which a graphics card can perform texture mapping
by hassan-mujtaba (Sep, 2013)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.
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
by Ryan-Shrout (Oct, 2013)The R240 is built with a half-height PCB and includes 320 shaders running at up to 780 MHz.
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes
by hassan-mujtaba (Oct, 2013)The Radeon R9 280X is based on the 28nm Tahiti die featuring 2048 Stream processors, 128 Texture mapping units and 32 Raster Operators.

Working conditions in unregulated Litecoin mines are terrible and we're told many brave miners die in overclocking-related incidents.
The R9 280 is basically a rebranded HD 7950 Boost, it is almost identical, apart from slightly higher clocks.

However, until I see a swarm of parts on Newegg.com or Amazon.com at, or very close to, the MSRPs listed on the table above for an extended period, I think the effects of coin mining (and the rumors of GPU shortages) will continue to plague us.
No one wants to see competition in the market and great options at reasonable prices for gamers more than us!

The R7 265 is expected to fit well in the lower mid-range segment with a price tag of around US $149 to US $159 while the R9 280 should fit below R9 280X which is still a US $299 graphics card, at least on paper, so hopefully, we will see the R9 280 at around US $249.
The GPU should end up clocked at around 900MHz while the memory will work at 4.8GHz.

When it comes to discrete graphics, the $199 price point is known as the gamer’s sweet spot by both AMD and NVIDIA.
Read on to see what kind of performance boost you can expect and how much further you can push this card.
