A quote from the article:
We review the MSI Radeon R9-290X Gaming OC. The cards equipped with that Hawaii GPU now is proper cooled thanks to the TwinFrozr cooler and steadily running and purring at just over 70 Degrees C, that's under full gaming load. The 2816 Stream processor based Hawaii chip will get paired with 4 GB GDDR5 memory running along a 512-bit memory interface. The card itself is fully customized including component selection, custom PCB, custom cooling, well .. custom everything ! Powered through 8-Pin + 6-Pin power configuration it obviously runs at factory overclocked specifications as well. The card will clock towards 1040 MHz bit is clocked at reference clocks on the GDDR5 memory.MSI Radeon R9-290X Gaming OC review @ Guru3D
So what does a Hawaii GPU bring into the garphics cards ? Oh what about 6 Billion transistors on a 438 mm2 Die, 512-bit Memory bus with 4 GB - 5.0 Gbps GDDR5 memory, Ultra HD ready, 5.6 TFLOPS of compute performance. Not bad for keywords, eh? AMD is partnering with EA's Battlefield 4, meaning that for as long as the coupons are available, you will receive Battlefield 4 with the card for certain selected SKUs. That would be a deluxe edition with extra DLC and weapons. AMD also is focusing strongly at gaming in Ultra High Definition (UHD), so this will be a focus in our review as well. Will we be able to play the hottest games at that whopping 8.2 Mpixels at a 3840x2160 resolution @ 60 Hz.
