Why ould be questionable at all. RV770 crippled chips doesnt clock as much RV740 and certainly consume twice as much power as RV770 does. And even more it's poor way to push people pay the same price for a card that's much less than 4830 card considering poor memory bandwidth and built around binned less performing chips than HD4830.
PowerColor, a graphics cards supplier that belongs to Tul Corp., this week officially launched its ATI Radeon HD 4730 graphics card. The company hopes that the launch of the PCS HD4730 will boost sales of its entry-level products.
“PCS HD4730 is created to be the new performance and price leader. If you have a limited budget but would like to have a powerful upgrade to take all games to the extreme, the PCS HD4730 is the best choice for you,” said Ted Chen, chief executive officer of Tul Corp.
ATI Radeon HD 4730 is based on the code-named ATI RV770 graphics processing unit (GPU) made using 55nm process technologies. The Radeon HD 4730 features 640 stream processors, 32 texture units, 16 render back ends and 128-bit GDDR5 memory controller. PowerColor PCS4730 clocks GPU at 700MHz and memory at 3600MHz.
Clock-speeds of the Radeon HD 4730 imply that performance of the graphics board will be very close to that of the Radeon HD 4770, which sports 750MHz/3200MHz frequencies for core/memory. As a result, the model number of the HD 4730 is rather questionable and a more logical one would be HD 4750.
ATI Radeon HD 4730 supports all the technologies as the rest ATI Radeon HD 4000-series family members, including DirectX 10.1, hardware high-definition video acceleration, HDMI with audio output, PCI Express 2.0 and so on.
PowerColor PCS HD4730 equipped with Arctic Cooling cooler that increases air flow at a lower fan speed that easily dissipates heat from the heat sink. The fan design avoids direct contact with high temperatures emanating from heat sink, extending the life cycle of the cooling fan. With PowerColor fan control technology, the fan speed can be adjusted automatically providing a perfect balance between silent operating environment and cooling performance.
PowerColor PCS HD4730 will retail for US$79.99 and will be available on June 8.
