AMD Radeon HD 7790

The Radeon HD 7790, also known as "Bonaire", is a half-generation of the Radeon HD 7000 series video cards. It was launched on March 22nd, 2013, with a base price of $149. The launch also brings more enhancements to the AMD PowerTune technology, which means higher sustained clocks, more performance, and improved power efficiency.

The Radeon HD 7790 GPU itself is comprised of 2.08 billion transistors packed into 896 stream processors with a clock speed of 1GHz. There are 56 texture units, 64 Z/stencil units, and 16 ROPs. The Radeon HD 7790 is designed to be paired with 1GB of GDDR5 memory on a 128-bit bus, running at 1500MHz for a 6.0Gbps data rate and a maximum theoretical bandwidth of 96GB per second. The Radeon HD 7790's typical board power is just 85 Watts.

While a standard Radeon HD 7790 is designed to run at 1GHz, PowerColor has taken the liberty to add a factory overclock to its board. The overclock added an additional 75MHz or 7.5% faster speeds, bringing the core operating speed up to 1075MHz. The PowerColor Radeon HD 7790 TurboDuo supports 1GB of GDDR5 memory, which will run at the standard 6GHz. These clock speeds put the PowerColor Radeon HD 7790 TurboDuo in line to compete with all major brand name companies that have released customized versions of the HD 7790.

The key feature that PowerColor is debuting with this video card is the TurboDuo cooling system. The TurboDuo cooling system begins its cooling with a single S-shaped copper heat pipe that directly contacts the GPU. The copper heat pipe carries heat from the GPU and distributes it to three sections of the heatsink. The heatsink is made of aluminum and is designed with many small fins. Each fin adds more surface area for heat to spread to. The two fans will blow directly across the heatsink to remove the heat that gathers on each fin. Located on the back of the PCB is the aerodynamics kit which are dual cooling vents designed to increase airflow and assist heat dissipation. Heat will be partially be exhausted through these into the case, and then out of the case via the rear exhaust fan. PowerColor states that the TurboDuo cooling technology provides the board 10% cooler operating temperatures while remaining 5% quieter than the reference design.

The PowerColor Radeon HD 7790 TurboDuo video card is currently available at Newegg for $164.99. This offer also includes two free games - Far Cry 3 - Blood Dragon and BioShock Infinite, a total value added value of $75. PowerColor also offers a free 2 year limited parts and labor warranty with this video card. You can read more about the PowerColor Radeon HD 7790 TurboDuo's specifications and features here.

The PowerColor Radeon HD 7790 TurboDuo itself is dominantly black, with red trim surrounding the two fans. The two fans are black with a glossed finish. Directly below the fans is the finned aluminum heat sink which stretches 6 and 5/8th inches in length and 2.25 inches in length. The PowerColor Radeon HD 7790 TurboDuo is printed on a black PCB which brings the black and red color scheme together. There are two small cutouts on the back of the PCB which help direct more airflow off the video card and into the case to be exhausted by the rear PC fan.

The PowerColor Radeon HD 7790 TurboDuo requires a single 6-pin PCIe power connector which is located on the back edge of the video card opposite the I/O panel. In order to operate properly PowerColor suggests using a 500W or greater power supply for single operating mode, and a 600W power supply if using AMD CrossFire. The rear I/O panel houses a Dual-Link DVI-I connector, a Dual-Link DVI-D connector, an HDMI connector, and one DisplayPort connector. The PowerColor Radeon HD 7790 TurboDuo measures 8.25 inches in length, 1.5 inches wide, and 4 inches tall. It will require two spots in your case.
