The AMD Radeon HD 7790 came out late March and it's still AMD's main product for the £80-£130 price segment. While the Radeon HD 7790 cards are facing strong competition from the Nvidia GeForce GTX 650 Ti Boost, the 1GB models from AMD are certainly still interesting due to their low price. We already tested Radeon HD 7790 cards from ASUS, MSI and Sapphire. Today we'll take a closer look at the XFX Radeon HD 7790 Black Edition 1GB, and compare its performance and price to the other 7790 cards.
The XFX Radeon HD 7790 Black Edition 1GB is equipped with XFX's Dual Dissipation cooler with two fans. The heatsink contains two standard heatpipes. The aluminium frame gives the card a stylish appearance, and the XFX logo in the I/O bracket shows the designers definitely have an eye for detail.
The clock frequency for the GPU is set at 1,075MHz, higher than the 1,000MHz on the standard Radeon HD 7790, but the same as the ASUS and Sapphire cards we tested. The memory speed is also the same as on the cards from ASUS and Sapphire, with 1,600MHz instead of the standard 1,500MHz on AMD's reference card.
The XFX card is equipped with 1GB GDDR5 video memory. The monitor connectors are unchanged, with HDMI, DisplayPort and two DVI ports. The card features the standard PEG6 power connector.
The price is a bit on the high side, however. £123 is more than what the Radeon HD 7790 1GB cards from ASUS, Sapphire and MSI cost. We'll see whether there is a reason for the higher price.
We used our standard graphics card testing setup, consisting of an Intel Core i7 3960X (Sandy Bridge-E), 16GB Corsair DDR3-1600 RAM, an ASUS P7X79 Pro motherboard, a Samsung Spinpoint F1 hard disk, a Cooler Master Silent Pro Gold 1200 Watt power supply and Windows 7 x64. All tests were done in 1,920 x 1,080 Full HD resolution, what the cards are intended for. You can read the rest of XFX Radeon HD 7790 Black Edition 1 GB preview on Hardware.info.
