The Galaxy GTX 460 WHDI Graphics Card
In most ways, the Galaxy GTX 460 WHDI is just a normal graphics card with a few things both internally and externally that would make it stand out from the crowd at a LAN part.

The outside of the box makes sure you realize that some wireless things are happening here with the WHDI logo prominently displayed.

The WHDI card is a bit longer than your standard GTX 460 card and you’ll see why once we tear off the cover.  The metal cover is a bit loose feeling and surely helps with some shielding for the transmitter antennas below it.

The card still requires a pair of 6-pin PCIe power connectors to operate.

Looking at the connections on the card you see a couple of standard ones: a dual-link DVI output and a DisplayPort connection.   There are five standard antennae connections that look familiar to anyone that is seen a desktop WiFi card or a motherboard with WiFi built on and those will indeed be used to transmit the WHDI data to the receiver.  The mini-USB connection there is used to flash the firmware on the WHDI chip; very forward looking of Galaxy and handy for users going forward.

These are five antennas…

The back side of the card doesn’t really reveal anything about the secrets within but removing the cover might.  What the back does reveal is the lack of an SLI connection on this card – disappointing considering doubling up the performance of the GTX 460 would take away any issues of the best quality gaming at 1080p resolutions.

Under the hood we see the GTX 460 GF104 GPU and the 1GB of GDDR5 memory that all cards of the same chip contain but it is the tangle of wires and shielding to the left that is more interesting.

The AMIMON 2120 transmitter chip is located in the image above, sticking out just below the silver shielding panel, attached to the riser card.  This complicated mash-up of technology is what is required today to transmit as much as 3 Gbps of bandwidth throughout a home, or in this case, just to the receiver box Galaxy includes.

Included in the box with the Galaxy GTX 460 WHDI card are your standard allotment of accessories including a pair of power adapters, DVI-to-VGA converter, instructions and driver disc.  The two USB cables are used for firmware updates of the logic on the WHDI card and receiver as well as another neat feature we’ll mention below.

To complete the WHDI connection you’ll need the receiver shown above.  A small box that measures about 6″ x 4″ without the stand includes the AMIMON 2220 receiver controller and outputs and HDMI connection to your desired monitor, TV, receiver, etc.  Galaxy did include a 6′ HDMI cable as well.
