You cannot leave ASUS out of the bunch when it comes to the Radeon HD 7790 graphics card. Like most manufacturers of the “Bonaire” based card they have two versions as well. They have a reference design and their OC Edition which does feature ASUS’s own DirectCU II cooling as well. The HD7790-DC2OC-1GD5 runs overclocked at a 1075MHz core, 6400MHz memory and does come with ASUS’s GPU tweak utility.
Today we are taking a look at a brand new video card from Sapphire. We have been hearing about the Radeon 7790 over the past few weeks and earlier this year AMD said we would see an HD 8000 series towards the end of the year and they would be refreshing their HD 7000 lineup with new chips. The HD 7790 is the first card that is part of this refresh, based on the brand new “Bonaire” 28nm graphics processor. The Bonaire graphics processor is based off of AMD’s graphics core next (GCN) architecture and features 896 stream processors. We are looking at Sapphire’s version, which is the HD 7790 OC with Dual-X. The Dual-X is for Sapphire’s own unique cooling system on the card. This card features a 1075MHz core clock, 1GB of GDDR5 memory and has dual DVI, HDMI and DisplayPort connections. This card is setup to compete directly with Nvidia’s GTX 650 Ti. Read on as we take a look…
Here are some of the first photos of the Sapphire HD 7790 Dual-X. This is Sapphire’s premium offering based on AMD’s new GPU. This dual slot card features Sapphire’s in-house PCB and cooler designs. As you can see from the photos the PCB and shroud are both black. The cooler is made up of an aluminum fin stack design, which is ventilated by a pair of 80mm fans. The card is powered by a single 6pin PCIe connector and outputs include a pair of DVI ports, HDMI and DisplayPort.
