Specifications of the ATI Mobility Radeon HD 3670 GPU


Launched in January 2008, ATI Mobility Radeon HD 3670 mobile Graphics Processing Unit makes use of Unified Superscalar Shader architecture, and is built on 55 nm technological process. The card has 680 MHz graphics clock frequency. It also has 120 stream processors, 8 texture units, as well as 4 color ROPs. The Mobility Radeon HD 3670 embeds 1 GB of GDDR4 memory. Because the memory operates at 800 MHz, and utilizes 128 bit bus, the effective memory bandwidth is 25.6 GB/s. The GPU supports PCI Express 2.0 interface. This model needs up to 30 Watt of power.
