| This is the R9 290X GPU Battlefield 4 edition, available from newegg for ~$580 a pop. It comes bundled with a AMD code which allows you to download Battlefield 4 from Origin / EA. The card is a 3D gaming monster with fluid fps for 3D shooter games like BF4. The ASIC has > 6Billion transistors and beats any gaming console in 3D graphics quality. It replaces my old Powercolor 7990 Devil 13 edition on my gaming PC. BTW, for crypto-currency miners, it mines LTC / scrypt at 750Kh/s at default settings. Just change shaders to (2810 or 2816) in the cgminer configuration file.  |
| The R9 290X GPU board. It has 2 DVI-D, one HDMI full size, and one DisplayPort full size connector. The GPU is fed by a 6 phase power supply. Two PCIE power sockets (8Pin + 6Pin) power the board. The GPU fan speed is kept under check until it reaches 95C and then the fan speed is gradually increased to 40%, and then the GPU is downclocked automatically to keep noise under control. The BIOS switch can choose between silent and uber, to adjust fan speed, cooling, speed and thus heat generation. |

| The R9 290X die and the 16 GDDR5 chips. The GPU runs at 1GHz, and RAM at 1250MHz. So far the biggest gpu die ATI / AMD has produced at 28nm. It has 2816 shaders and lots of texture units (176). Compare that to 2048 shaders in Radeon 7970. Memory bus width is 512bit. |

The GDDR5 RAM chip is made by Elpida EDW2032BBBG, the 2Gbit chip

| The heatsink + fan is regular AMD Radeon affair. Fan is loud at >60% speed. |
