ATI Radeon HD 4730 Image ATI RV770 Image
The Radeon HD 4730 was an entry-level graphics card by ATI, launched in June 2009. Built on the 55 nm process, and based on the RV770 graphics processor, in its RV770 CE variant, the card supports DirectX 10.1. The RV770 graphics processor is an average sized chip with a die area of 256 mm² and 956 million transistors. Unlike the fully unlocked Radeon HD 4870 Mac Edition, which uses the same GPU but has all 800 shaders enabled, ATI has disabled some shading units on the Radeon HD 4730 to reach the product's target shader count. It features 640 shading units, 32 texture mapping units and 8 ROPs. ATI has placed 512 MB GDDR5 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 750 MHz, memory is running at 900 MHz.
We recommend the ATI Radeon HD 4730 for gaming with highest details at resolutions up to, and including, 1024x768.
Being a dual-slot card, its power draw is rated at 110 W maximum. Display outputs include: 2x DVI, 1x S-Video. Radeon HD 4730 is connected to the rest of the system using a PCIe 2.0 x16 interface. The card measures 241 mm in length, and features a dual-slot cooling solution. Its price at launch was 79 US Dollars.
