AMD Radeon HD 6390 Image AMD Redwood Image
The Radeon HD 6390 was a graphics card by AMD, launched in July 2011. Built on the 40 nm process, and based on the Redwood graphics processor, in its Redwood LE variant, the card supports DirectX 11.0. The Redwood graphics processor is an average sized chip with a die area of 104 mm² and 627 million transistors. Unlike the fully unlocked Radeon HD 6510, which uses the same GPU but has all 400 shaders enabled, AMD has disabled some shading units on the Radeon HD 6390 to reach the product's target shader count. It features 320 shading units, 16 texture mapping units and 8 ROPs. AMD has placed 1,024 MB DDR2 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 550 MHz, memory is running at 500 MHz.
We recommend the AMD Radeon HD 6390 for gaming with highest details at resolutions up to, and including, 800x600.
Being a single-slot card, the AMD Radeon HD 6390 does not require any additional power connector, its power draw is rated at 39 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x HDMI. Radeon HD 6390 is connected to the rest of the system using a PCIe 2.0 x16 interface. The card measures 165 mm in length, and features a single-slot cooling solution.
