AMD Radeon R9 280X, Radeon R7 260X, Radeon R7 240 Specifications Confirmed – October 8th Launch


Specifications for AMD's upcoming Radeon R9 280X (Tahiti XT), Radeon R7 260X (Bonaire XTX) and Radeon R7 240 (Oland Pro) have been unveiled. As noticed earlier, the Radeon R9 and R7 lineup are mostly rebrands except the high-end R9 290 Series which would feature the latest Hawaii chip.

AMD Radeon R9 280X, Radeon R7 260X, Radeon R7 240 Specifications Confirmed

The Radeon R9 280X is a Tahiti rebrand but would arrive at a price of only $299. The same GPU launched at $549 and with almost two years of experience at hand, manufacturer's would now be able to offer some highly clocked models of the Radeon R9 280X GPU to users. The specifications of the GPU are virtually the same over the AMD Radeon HD 7970 including 2048 stream processors, 32 ROPs, 128 TMUs and a 3 GB GDDR5 memory operating across a 384-bit wide memory interface. The card would be clocked at 1000 MHz at base and 1050 MHz with GPU Boost while the memory would be clocked at 1500 MHz or 6 GHz effective clock speed.

But like i said, manufacturer's have almost two years of experience with the chip and most would go for the factory overclock route to gain more fame. We found out that some manufacturer's would have the GPU core clocked high to 1070 and upto 1100 MHz with a few variants such as the ASUS Matrix R9 290X which was found out by Videocardz. 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. This makes the bandwidth of the card comparable to the Radeon R9 290 series which has a bandwidth of over 300 GB/s, nothing short of amazing for an two year old GPU.

The rest of the card specifications confirmed include the $139 Radeon R7 260X which is a Radeon HD 7790 rebrand featuring 896 Stream processors, 16 ROPs, 56 TMUs and a 2 GB GDDR5 memory running across a 128-bit wide memory interface. The core clock is maintained at 1100 MHz while memory operates at 1625 MHz. This is a reference model and one can expect higher factory overclocked cards at launch on October 8th-10th. Lastly, is the $89 Oland Pro based Radeon R7 240 which is the entry level Volcanic Islands chip featuring 320 Shaders, 8 ROPs and 20 TMUs. The card is shipped with a Gigabyte of memory running across a 128-bit interface while clocks are maintained at 780 MHz for the core and 1150 MHz for the memory. Its bigger brother, the Radeon R7 250 which is based on the Oland XT GPU would feature 384 shaders, upto 2 GB GDDR5 memory along a 128-bit interface and faster clock speeds.
