Mobility Radeon HD 4830

Specifications of the ATI Mobility Radeon HD 4830 GPU

ATI Mobility Radeon HD 4830 mobile Graphics Processing Unit was introduced in March 2009. The card makes use of Unified Superscalar Shader architecture, and it is manufactured on 40 nm technological process. The cards graphics frequency is 550 MHz. Furthermore, it has 640 stream processors, 16 color ROPs, together with 32 texture units. The Mobility Radeon HD 4830 incorporates 1 GB of GDDR3 memory. Since the memory is clocked at 700 MHz, and utilizes 128 bit bus, the effective memory bandwidth is 22.4 GB/s. The GPU supports PCI Express 2.0 interface. 3D graphics and gaming performance of the ATI Mobility Radeon HD 4830 can be improved if it is paired with a similar graphics card.
