ATI has paired 256 MB GDDR3 memory with the Radeon HD 4650, which are connected using a 128-bit memory interface. It features 320 shading units, 32 texture mapping units, and 8 ROPs. The RV730 graphics processor is an average sized chip with a die area of 146 mm² and 514 million transistors. Since Radeon HD 4650 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. Built on the 55 nm process, and based on the RV730 graphics processor, in its RV730 PRO variant, the card supports DirectX 10.1. Its most important component is the graphics processing unit, which is a dedicated processor that is used to accelerate graphics, making it possible to distinguish 3D and 2D images.The Radeon HD 4650 was a graphics card by ATI, launched on September 10th, 2008. A video card or graphics card has different components that come into play for this: a graphics processing unit, video BIOS, video memory, RAMDAC, outputs, motherboard interface, cooling devices and power. The ATI Radeon HD 4600 series give great video outputs as they accelerate the images of 3D scenes and 2D graphics. It can be compared to fairly high-end graphics cards as far as overall performance and video quality are concerned. While doing all this, the ATI Radeon HD 4600 series also has breakthrough energy-efficient technology providing easier installation and minimum energy usage. Microsoft DirectX 10.1 games are supported. AMD has given it 320 stream processing units and a maximum memory of 1GB. The ATI Radeon HD 4600 series combines 514M transistors put together using a 55nm process, PCI Express (2.0×16) bus interface and DDR3/GDDR3/DDR2 memory interface.
