Powercolor is going to launch a total of five cards in its HD 4600 series. Two of them will be based on the RV730XT and three on the RV730Pro GPU. Both of the cards from the HD 4670 series will use Zerotherm cooler, which should do a great job in keeping the RV730 GPU at low temperatures.

The first two cards are based on the RV730XT GPU, and the only difference on them is the amount and the clock of the memory. The first one, branded PCS HD 4670 512MB, comes with 512MB of memory which works at 1,000MHz and the GPU is clocked at 750MHz. The second one also works at 750MHz for the GPU, but comes with 1GB of DDR3 memory clocked at 873MHz. This one is branded PCS HD 4670 1GB. Both of them, of course, use the 128-bit memory interface and come with support for DirectX 10.1, PCI-E 2.0, CrossfireX and HDMI.

Powercolor's HD 4650 series will have a total of three cards for now. We already wrote about the passively cooled SCS3 version and the other two are a bit unknown, as Powercolor didn't list them or show their picture at its Website. Both of the cards work at 600MHz for the GPU and both have the DDR2 memory working at 500MHz. The only difference is the amount of memory, as one comes with 512MB and the other one has 1GB of memory.

Here are the pictures of the PCS HD 4670 series.
