AMD Radeon HD 8790M Image AMD Mars Image
The Radeon HD 8790M is a graphics card by AMD, launched in April 2013. Built on the 28 nm process, and based on the Mars graphics processor, in its Mars XTX variant, the card supports DirectX 12.0. The Mars graphics processor is a relatively small chip with a die area of only 77 mm² and 1,040 million transistors. It features 384 shading units, 24 texture mapping units and 8 ROPs. AMD has placed 2,048 MB GDDR5 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 850 MHz, which can be boosted up to 900 MHz, memory is running at 1000 MHz.
We recommend the AMD Radeon HD 8790M for gaming with highest details at resolutions up to, and including, 1280x720.
Being a mxm module card, the AMD Radeon HD 8790M does not require any additional power connector, its power draw is not exactly known.
