Sapphire 7790 Dual-X OC

The Sapphire Radeon HD 7790 Dual-X OC is named after its cooler, a dual fan design with two 8mm diameter copper heatpipes embedded in an aluminum base that covers both GPU and all four memory chips. The PCB is intriguing, a large part of the back end is blank, left presumably to avoid an overhang from the cooling system. Priced at $159USD, it will be available with a free Bioshock Infinite download key.

The Sapphire Dual-X OC ships with a factory overclocked core and memory, running at 1075MHz engine and 1600MHz / 6.4Gbps QDR memory, respectively.


The power input is side angled, to aid with use in smaller form factor PCs using micro-ATX mainboards.

6-pin PCI-E power input

The reference display output options have been changed, with the two mini-DisplayPort outputs replaced with a single full DisplayPort output. HDMI 1.4a and dual DVI (one single link, one dual link).

Display Outputs

The bundle includes driver CD (don't use it, grab the latest from AMD instead); Crossfire bridge cable, DVI-VGA adapter, 4-pin Molex to 6-pin PCI-E power adapter, Sapphire Select club Gold registration details, and a HDMI cable.
