(GCN) architecture. SAPPHIRE claims that the new card
delivers a significant graphics performance boost for Mac Pro users
in a wide range of applications including gaming, audio or video
editing and content creation. For example, gaming frame rates are

support for Open GL 4.2 and Open CL 1.2 as well as AMD HD3D
technology and APP acceleration.
AMD's GCN architecture supports a number of post-processing and
scaling operations. These include de-blocking, de-noising,
automatic de-interlacing, Mosquito noise reduction and edge
enhancement as well as image quality enhancement technology, such
as adaptive anti-aliasing and 16x angle independent anisotropic
texture filtering. The SAPPHIRE HD 7950 Mac Edition features AMD
PowerPlay technology which provides automatic power management
during operation and ensures low power consumption under idle
Integrated display support includes two mini DisplayPort outputs

The card also features a 3 GHz HDMI 1.4a port. This output also
supports a maximum resolution of 3840 x 2160.
Finally, there is a Dual-link DVI port with HDCP, which supports a
maximum resolution of 2560 x 1600. As this is a DVI-I port it can

Edition supports Mac OS X/Windows under non-UEFI compliant mode and
in the other it supports Windows with UEFI hybrid firmware enabled.
A Windows driver disk is also included.
Under Windows, additional features are supported, including
hardware acceleration of video decoding, HDMI audio pass through
and additional display resolutions.
