ATI Technologies announced the newest family member of the Radeon X1800 series, the Radeon X1800 GTO. The card has 12 pixel shader processors, a 256-bit GDDR3 memory interface and operates at 500 MHz core and 1000 MHz memory speeds.

Based on the R520 core and has all the relevant features we expect from ATI's latest cards:
- Ultrathreaded SM 3.0 Engine Architecture with fast dynamic branching
- 500 MHz Core Speed
- 1000 MHz Memory Speed
- 12 Pixel Shader Processors
- 8 Vertex Shader Processors
- 512-bit Ring Bus memory controller
- 256-bit GDDR3 memory interface
- Avivo Technology: unparalleled video & display quality, H.264, HDTV, 10-bit display processing engine
- Dual-Dual-link DVI
- Supports HDR with Anti-aliasing
- CrossFire

As you can see the card is very similar to the X1800XL, just with 4 less pixel Shader processors. In ATI's press briefing material for the GTO they only mention the 512 MB X1800XL and no longer the 256 MB X1800XL. With similar performance but a lower price the X1800GTO is a much more cost-efficient card and thus much more interesting for us consumers.
