Built for gaming at high resolutions, ASUS Strix Radeon R9 390 Graphics Card features 8GB of GDDR5 vRAM ,graphics coupled to 2560 Stream Processors running at a base speed of 1050 MHz with a 512-bit memory bus with a 384 GB/s bandwidth. The effective memory clock speed is 6000 MHz. The output panel features DVI-D, DisplayPort, and HDMI outputs. -The HDMI and DisplayPort outputs support resolutions of up to 4096 x 2160. 4K Support Display graphics, games, and video in UHD (3840 x 2160) and Cinema 4K (4096 x 2160) for increased detail on 4K resolution displays. Games which support 4K resolutions will display greater detail for enhanced realism and reduced artifacts. 4K video from services such as Netflix and YouTube can deliver full resolution video for an enhanced media experience. VSR AMD's Virtual Super Resolution is a scaling utility. It uses the GPU architecture in order to take advantage of 4K capabilities with lower screen resolutions by having the graphics card render at higher resolutions and then intelligently down-sample the output to fit the smaller screen. Aliasing and jagged artifacts are reduced on down-scaled rendering compared to a native resolution rendering. AMD's FreeSync Technology allows for communication between the graphics card and a monitor with FreeSync support. Having this communication enables the monitor to dynamically adjust its refresh rate to the frame rate being output by the graphics card, thereby greatly reducing tear
