Sapphire's real strength isn't the overclock what matters is whether or not the Dual-X cooler has the ability to control the thermal ceiling in order to keep the GPU running at the highest possible frequency for as long as possible. AMD Radeon R9 280: AMD Radeon R9 Series: AMD Radeon R9 200 Series: Component: Up to 933 MHz: 1792: 3GB: Up to 240 GB/s: No: Yes: Yes: No: Catalyst Software, AMD HD3D Technology, AMD TrueAudio Technology, Unified Video Decoder (UVD), AMD Gaming Evolved Client, AMD LiquidVR Technology, AMD TressFX Hair, AMD Eyefinity Technology. Graphics, Nvidia GTX 770 / AMD Radeon R9 280, Nvidia GTX 1060 6GB / AMD. This allows you to configure multiple monitors in order to create a more immersive gaming experience, such as having a wider field of view. Graphics, Nvidia GTS 450 / AMD Radeon HD5770, Nvidia GTX 560 / AMD Radeon HD5870. That doesn't sound like much, but keep in mind that the real-world clock rate is limited by temperature. The graphics card supports multi-display technology. With a 940 MHz peak frequency, Sapphire's Dual-X R9 280 OC has the highest GPU clock rate of any of these options, although it beats the reference Radeon R9 280 by a mere 7 MHz. Based on specifications, this upcoming graphics card has raw performance similar to the Radeon R9 280 it is likely to replace, at the same 250 price point. The upcoming Radeon R9 285 marks the first bump in memory clock for this class of AMD card at 1375 MHz (5.5 GT/s effective, the same as the Radeon HD 7970), but this is more than offset by a thinner 256-bit memory interface, and its maximum GPU boost clock rate drops slightly to 918 MHz. Of course, all of those cards use 1250 MHz (5 GT/s effective) GDDR5 memory. GPU Manufacturer: AMD Specs status: Official GPU Series: Radeon R9 200 GPU Model: Tahiti PRO2 Fabrication Process: 28nm Stream Processors: 1792 TMUs: 112. AMD has a rich history of iterating its Tahiti GPU in the 1792-shader configuration, from the 800 MHz Radeon HD 7950 to the 933 MHz (peak) Radeon R9 280.
