FireGL X3-256: specs and benchmarks

Summary

ATI started FireGL X3-256 sales 3 August 2004 at a recommended price of $1,099 . This is a R400 architecture desktop card based on 130 nm manufacturing process and primarily aimed at designers. 256 MB of GDDR3 memory clocked at 0.45 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 29.06 GB/s.

Compatibility-wise, this is a single-slot graphics card attached via AGP 8x interface. 1x Molex power connector is required, and power consumption is at 57 Watt.
