ATI Radeon X1800 GTO²: specs and benchmarks
Summary
ATI started Radeon X1800 GTO² sales 1 March 2006. This is a desktop graphics card based on a R500 architecture and made with 90 nm manufacturing process. It is primarily aimed at gamer market. 256 MB of GDDR3 memory clocked at 0.5 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 32 GB/s.
Compatibility-wise, this is a single-slot graphics card attached via PCIe 1.0 x16 interface.
