[Techpowerup.com] PowerColor HD 7970 X2 Devil 13 Taken Apart
Here are the first pictures of PowerColor's ambitious Radeon HD 7970 X2 Devil 13 dual-GPU graphics card taken apart. The pictures reveal a PCB that's both longer and taller than that of the HD 7970, to create room for two 28 nm "Tahiti" GPUs, a total of 24 GDDR5 memory chips (12 on each side), a PLX PEX8747 PCIe 3.0 bridge chip, and a VRM that consists of 5+2+1 phases per GPU system. The card draws power from three 8-pin PCIe power connectors. The VRM consists of solid-state chokes and Renesas Driver-MOSFETs. Display outputs include two each of DVI and mini-DP, and an HDMI. Each GPU system has a pair of BIOS'es (performance and failsafe).
