AMD RADEON HD 3870 VS R7 240 SERIES
^ These series do not fully comply with OpenGL 2+ as the hardware does not support all types of non-power-of-two (NPOT) textures.^ Radeon 7000 Series has programmable pixel shaders, but do not fully comply with DirectX 8 or Pixel Shader 1.0.Note that this table include micro-architectures not used in the APUs, and a branding series might include older generation chips. The following table shows the graphics and compute APIs support across AMD GPU micro-architectures. Support in this table refers to the most current version.
^ a b DRM ( Direct Rendering Manager) is a component of the Linux kernel.Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed. ^ To feed more than two displays, the additional panels must have native DisplayPort support.
HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup. A compatible HDCP display is also needed for this.
^ a b To play protected video content, it also requires card, operating system, driver, and application support. ^ Unified shaders : texture mapping units : render output units. ^ Single-precision performance is calculated from the base (or boost) core clock speed based on a FMA operation.
