New Features

Eyefinity 2.0Eyefinity 2.0

Eyefinity™ 2.0 technology features all-new support for Stereo 3D, universal bezel compensation and brand new display configurations which allows the user to configure custom resolutions and the ability to relocate the Windows task bar to an arbitrary screen.


DDMADigital Multi-Point Audio (DDMA)

The next step in audio output from a graphics card. Traditionally video cards has been able to output audio through the HDMI port and audio has been restricted to to a single device, be it a monitor, HDTV or a receiver.

With DDMA now you can send audio to multiple devices via the DisplayPort combined with the HDMI.

Imagine a video conferencing where each attendee is mapped to a monitor and with DDMA set on each monitor speaker set.

GCNGraphics Core Next (GCN) Architecture and AMD App Acceleration

A revolutionary new architecture. Jump right into GPGPU applications today with Microsoft C++ AMP™ and OpenCL™ for spectacular performance with the GCN architecture. From video editors to Internet browsers, AMD App Acceleration™ is a supercharger for everyday applications. The Club 3D Radeon™ HD 7990 Dual GPU was engineered for the revolution in GPU compute.

ZeroCore Power

Power consumption

AMD introduced with the Southern Islands chipset their long idle power saving technology. Now the graphic card can turn off most of its functional units of the GPUs, when they are unused, leaving only the PCI Express bus and other components active. This as a result, reduce the power consumption from 30W at idle to under 3W in long idle, a power level low enough that ZeroCore Power shuts off the fan as there is no heat generated further saving energy.

ZeroCore Power will put CrossFire™ grapic cards in ZCP when not in use.







AMD HD3D™ is a technology designed to enable stereoscopic 3D support in games, movies and/or photos. Additional hardware (e.g., 3D-enabled panels, 3D-enabled glasses/emitter, Blu-ray 3D drive) and/or software (e.g., Blu-ray 3D discs, 3D middleware, games) are required for the enablement of stereoscopic 3D. Not all features may be supported on all components or systems—check with your component or system manufacturer for specific model capabilities and supported technologies. AMD HD3D™ technology is enabled on AMD Radeon™ HD 7000 Series GPUs and above using Catalyst 12 or later.

HDMIFAST HDMI technology

With the introduction of the HD 6000 Series, HDMI 1.4a implementation allows the graphics card to enable Stereo 3D on HDTVs or monitor displays, this same feature is also found on the new HD 7970. Now with the introduction of HDMI support for 4K x 2K displays, the HD 7970 is now able to run 4K x 2K displays (max resolution 4096x3112) over HDMI along with being able to support 1080p Stereo 3D at 120fps (60Hz/eye), with the current standard set at 48fps (24Hz/eye).

Extendable support pod

To enhance graphic card durability and to relieve pressure from the graphic card and the PCI Express slot of the motherboard, Club 3D developed an extendable support pod that works as a pillar underneath the graphic card, taking away any concerns about the bending of the graphic card or motherboard that may occur under the heavy load of hefty graphic cards. The suppod pod can be adjusted in height from 62mm to up to 150mm, maximizing compatibility when using a different PCI Express slot than the first slot on the motherboard.
