Specifications of the ATI Radeon X550 GPU


ATI Radeon X550 Graphics Processing Unit for desktop market segment was released in July 2005. The GPU is fabricated on 110 nm manufacturing process. The card has graphics clocked at 400 MHz. It also has 4 pixel shaders, 4 color ROPs, along with 4 texture units. The Radeon X550 embeds 256 MB of DDR memory. Because the memory operates at 250 MHz, and uses 128 bit bus, the effective memory bandwidth is 8 GB/s. The GPU supports PCI Express 1.0 interface, and requires a single motherboard slot. This model needs up to 45 Watt of power.
