In a bid not to lose market share, ATI, graphics business unit of Advanced Micro Devices, have responded to the launch of Nvidia Corp.’s GeForce GTX 460 with a price drop of the Radeon HD 5830 graphics card. The company claims that the model 5830 with the new price will be more competitive than the rival, but the rivalry will still not be easy.
Starting recently, the official recommended price of ATI Radeon HD 5830 1GB graphics card will be $199 in the U.S., which is equal to the price of Nvidia GeForce GTX 460 768MB. Earlier the manufacturer suggested retail price of the Radeon HD 5830 1GB was $239. Several leading online stores in the country have already started to sell the model 5830 at the new MSRP. There are also a number of advanced versions of the Radeon HD 5830 with increased clock-speed and special cooling systems that are sold at higher price-points.
ATI Radeon HD 5830 graphics card is based on the cut-down version of the code-named Cypress (RV870) graphics processor and features 1120 stream processors, 56 texture units, 16 render back ends, 256-bit GDDR5 memory controller and is clocked at 800MHz. ATI recommends its partners to install 1GB of 4.0GHz memory on the 5830 models graphics boards. The chip is fully compatible with DirectX 11; OpenGL 3.2/4.0; OpenCL 1.0; dual hardware full-HD video decoder that supports MPEG4-AVC, MPEG4-MVC, VC-1, Adobe Flash 10.1, WMV HD and so on; post-processing of high-definition video; built-in 7.1-channel audio core that can bitstream any loseless audio format, such as Dolby TrueHD, DTS HD Master Audio or LPCM via HDMI 1.3a;
The Radeon HD 5830 has a number of advantages over the GeForce GTX 460: it has 1GB of faster memory (4.0GHz vs. 3.60GHz) connected using 256-bit memory bus and generally has higher raw power performance (1.792 TFLOPS vs. 0.961 TFLOPS). However, the GTX 460 has higher amount of render back ends compared to the 5830 (16 vs. 24), has higher performance when performing tessellation operations and supports a number of Nvidia-exclusive technologies. Moreover, there are ATI Radeon HD 5830 graphics boards that utilize long print-circuit boards inherited from the Radeon HD 5870 and also consume too much power for sub-$200 graphics boards.
All in all, the best choice for $199 is not obvious and should be based on a comparison of two actual graphics cards, not abstract models.
