Sapphire's HD 7990 Atomic further detailed

Written by Slobodan Simic



12-layer PCB and 18-phase VRM


Sapphire's Radeon HD 7990 Atomic was unveiled at Computex, but now we have the first pictures of the actual PCB as well as the cooling solution. As seen earlier, the upcoming Sapphire HD 7990 Atomic will feature two 28nm Tahiti XT2 GPUs paired up with a total of 6GB of GDDR5 memory.

The custom 12-layer PCB will feature an impressive 18-phase VRM that will draw power from three 8-pin PCI-Express power connectors and feature PLX PEX8747 PCI-Express gen 3.0 x48 bridge chip. Each Tahiti GPU will feature its own 6+2+1-phase power supply for Vcc, VDDCI and MVDD and it will feature two sets of BIOS of each GPU. The display output configuration includes six mini-DisplayPort outputs and it should be able to pair up with any Radeon HD 7900 series GPU for CrossfireX action.

According to what can be seen from the leaked pictures, the cooler will feature a full-cover water block, 240mm radiator cooled by two 120mm 1200RPM fans and a reservoir+pump system.

Unfortunately, there are still no details regarding the actual clocks, price or the launch date of the new Sapphire HD 7990 Atomic.
