Specifications of the GIGABYTE Radeon HD 4650 Overclocked GPU


GIGABYTE Radeon HD 4650 Overclocked (part number GV-R465OC-1GI) is one of a few GIGABYTE desktop graphics processing units, based on ATI Radeon HD 4650 DDR2. The GPU, produced on 55 nm technology, employs Unified Superscalar Shader architecture. The card has graphics clocked at 650 MHz. Furthermore, it has 320 stream processors, 32 texture units, along with 8 color ROPs. The Radeon HD 4650 Overclocked comes with 1 GB of DDR2 memory. Because the memory operates at 400 MHz, and utilizes 128 bit bus, the effective memory bandwidth is 12.8 GB/s. The GPU supports PCI Express 2.0 interface, and needs a single slot on the motherboard. The maximum power draw of this model is 48 Watt, identical to the reference design. To boost GIGABYTE Radeon HD 4650 Overclocked game and 3D graphics performance, it can be paired with a similar card in crossfire mode.
