ATI Radeon HD 4600 graphics plaque series

AMD redefines with Radeon 4670 and Radeon 4650 what means mainstream graphic plaques.

AMD fulfill their promises and launches officially a new series of graphic plaques - ATI Radeon HD 4600 that intend to offer an exceptional performance for games and HD multimedia, at power consumption lower than one of a bulb. And all these at a very attractive price for graphic plaques from mainstream category.

4600 graphic plaque series are practically limited versions of 4800 series, with what AMD succeeded to overcome those from Nvidia. They are based on TeraScale graphic processor, realized in 55 nm and with 320 stream processors that is a modified RV770.

ATI Radeon HD 4670 works at a 750 MHz nuclear frequency, 2 GHz memory frequency, has a memory interface on 256 bits, and can include 512 MB or 1 GB of GDDR3 memory.

Less powerful version, ATI Radeon HD 4650, has a 600MHz nuclear frequency, 1GHz memory frequency, memory interface on 128 bits and includes 512 MB of GDDR2 memory.

Both of these plaques have 320 stream processors, 32 texture units and support DirectX 10.1, include Unified Video Decoder (UVD) 2.0 for HD video processing and HDMI 7.1 surround sound audio.

Plaques have a reduce power consumption, 60 W for 4670 and 50 W for 4650. Prices are extremely attractive, being smaller than initial estimations. So, HD 4670 with 512 MB of memory costs 80 dollars (version with 1 GB will appear later), and HD 4650 has a price of 60 dollars.

From initial reviews performance of these gadgets seems to be excellent, considering low power consumption and price. So HD 4670 is situated somewhere among Radeon HD 3650 or GeForce 9500 GT and Radeon HD 3850 or GeForce 9600 GT/GSO in some tests even overcoming them.
