ASUS Radeon R9 295X2 8 GB ‘Vesuvius’ Retail Model Spotted – Hybrid Air/Liquid Thermal Design
The first retail model of AMD's upcoming Radeon R9 295X2 graphics card has been spotted. The ASUS Radeon R9 295X2 sticks to the reference design and features 8 GB of GDDR5 memory along with the hybrid cooler which has air and liquid cooling combined.

The ASUS Radeon R9 295X2 'Vesuvius' features the Hawaii XT cores with GCN 1.1 architecture. With two Hawaii XT GPUs on the same board, the specifications equate to 2816 x 2 stream processors, 176 x 2 texture mapping units, 64 x 2 Raster Operators and 4 GB of GDDR5 memory on each chip which equates to a total of 8 GB GDDR5 memory. Double these and you get an impressive 5632 stream processors, 352 TMUs and 128 ROPs for an unprecedented amount of gaming and compute performance. Clock speeds are maintained at 1018 MHz for the core which is impressive considering AMD managed to clock their chip 18 MHz faster than the stock variant without worrying about the heat. This shows that the new cooling design has things well kept under control. The 8 GB GDDR5 memory runs across a 512-Bit X 2 memory bus that is clocked at 1250 MHz effective clock speed.
The card draws power from dual 8-Pin connectors which represent 300W while the PCI-E connector adds an addition 75W power so we are looking at a total of 375W TDP however the card is rated at 500W officially for the Radeon R9 295X2 graphics card . Each Hawaii core has a 5+1 Phase VRM which was the standard design on the Radeon R9 290X too and are coupled together via the PLX chip while the xDMA technologies will improve scaling efficiency. Display output include four Display Ports and a single DVI slot which will easily drive 4K Eyefinity resolutions and beyond. This will help drive games at 4K Eyefinity resolutions for better and immersive experiences.
To cool their Hawaii chips and a huge PCB with several VRMs, AMD adopted a neat new Hybrid cooling design they refer to as Project Hydra. AMD went with a 120mm radiator that can be equipped with two fans and assembled inside the PC chassis which leads two 38cm coolant pipes straight to each Hawaii core. The pump and radiator are made by OEM ASETEK who are the leaders in liquid cooling products for graphics and processor technologies. The cooler shroud is a neat new look from AMD that has a silver and black color theme and metal finish. Both the metal construction of the shroud and backplate helps keep the card stable under load avoiding any bends on the PCB and adds to the aesthetics of the card itself. The 92mm fan in the center is colored red and can be seen from the mesh circular opening which is a neat sight plus the fan and Radeon logo on the shroud illuminates Red color when the card is operational.
Update - Videocardz managed to score a couple of bare shots of the Radeon R9 295X2 PCB. As noticed earlier, the card measures 30.5 cm in length, two Hawaii chips (linked via the PLX chip), 4 GB GDDR5 memory chips for each core and a 5+1 Phase VRM. The PCB shots can be seen at the bottom of this article.
