The Powercolor HD4670 PCS is a video card that is slightly different than the norm. Different you say? The connectivity options for this one, make this card ideal for use in a home theater computer. The HD4670 is built around the RV730 GPU featuring 514 million transistors assembled using a 55nm process. Clock speeds are set to 750MHz on the GPU core and 1000MHz on the 512MB of GDDR3 memory that is sent through a 128bit bus. In addition to the connectivity options, Powercolor has used a thermal solution that was optimized by Zerotherm. If you have not heard of them, I suggest you take a look at the cooling solutions they bring to the table, as they are both innovative and most of all, they work.
Connectivity is what this card has. HDMI, DVI, and a little something new in the Displayport video-out connection. This connection is smaller and carries a bi-directional signal across the same amount of wires in a much more compact package. This port is the next big thing going for video connectivity. In one package, you should be able to connect to just about any display device. One thing powercolor does, is include protection for the connections on the card. All of the display connections, as well as the Crossfire connections, have a protective cover. The rear end of the HD4670 offers little other than the heatsink on the 512MB of GDDR3 memory. Along the spine of the HD4670 are the Crossfire X connections.
Pulling the Zerotherm optimized heatsink off the board you can see there is not much to see. The thermal paste applied is the same thick grey substance I see on many cards. No problem, just a lot of it. The six-pin connection seen below the HDMI out connection is the signal out connection for the HD-out port that comes attached to an expansion slot bracket. Just one more way to get the signal out for a total of four. The heatsink is an all aluminum block that keeps the temperatures in check when under a severe load. The RV730 GPU core is the centerpiece of the HD4670 and is built usiong a 55nm process for increased cost and energy savings.
Will this card be destined for a lacklustre life in a mundane desktop or better life in an HTPC? It all depends on what kind of horsepower it shows in the testing! It could be that card that fits in well in all types of systems.
