The Radeon HD 4600 series cards will be launched in about a week, on September 10, and AMD/ATI seems to have a few other plans for the third quarter of the year as well. The Sunnyvale company is expected to also announce the sub-$59 RV710-powered graphics this month – the cards will probably be known as the Radeon HD 4550 and HD 4350 and they should come as close competitors for Nvidia's GeForce 9400 and 9300 graphics.

 

AMD designed the Radeon HD 4600 series for the lower-end market, since the mid-range and high-end areas were already covered by the Radeon HD 4800 cards. The Radeon HD 4650 and 4670 graphics feature a 55nm RV730 chip, and support for DirectX 10.1 and CrossFireX, a 128-bit memory interface, UVD 2 and 320 Stream Processors. The price for the HD 4670 is believed to be set under the $150 segment.

 

Radeon HD 4670 is said to come with a 701MHz core clock and 512MB/1GB of GDDR3 clocked at 900MHz. The computing power of the card rises to 450GFlops, while the memory bandwidth goes up to 28.8Gbps. There will be 1 DVI and 2 DisplayPort interfaces available on this graphics solution. The Radeon HD 4650 comes with the core clock set at 600 MHz, and with 512MB of GDDR2/3 memory running at 500 MHz. It seems that there is also a second SKU in the works, featuring GDDR3 memory clocked at 667 MHz.

 

The Radeon HD 4550 and 4350 cards will feature 64-bit memory interfaces, PCI-Express 2.0 x16 interfaces, DirectX 10.1 support, PowerPlay 2.0 and the 2.2 version of the Unified Video Decoder. It seems that the Radeon HD 4550 will have the graphics processor clocked at 800 MHz, and 256 or 512MB of GDDR3 memory running at 800 - 900 MHz. The HD 4350 has an 800 MHz RV710 as well, but it packs only 256MB of GDDR2 memory running at 500 MHz. The Radeon HD 4550 boards are expected to hit the market by the end of September, while the second card will arrive at some point in the fourth quarter.
