The Radeon HD 4580 was a graphics card by ATI, launched in November 2011. Built on the 55 nm process, and based on the RV635 graphics processor, in its RV635 PRO variant, the card supports DirectX 10.1. Since Radeon HD 4580 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The RV635 graphics processor is an average sized chip with a die area of 135 mm² and 378 million transistors. It features 120 shading units, 8 texture mapping units, and 4 ROPs. ATI has paired 512 MB GDDR3 memory with the Radeon HD 4580, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 796 MHz, memory is running at 693 MHz.
Being a single-slot card, the ATI Radeon HD 4580 does not require any additional power connector, its power draw is rated at 65 W maximum. Display outputs include: 2x DVI, 1x S-Video. Radeon HD 4580 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 190 mm in length, and features a single-slot cooling solution.
