Product: Radeon X800GTO IceQII Turbo
Company: HIS
Authour: Mark 'Ratchet' Thorne
Date: November 3rd, 2005
Specifications

Like the X800GT, the GTO can be built using one of three different graphics core: the R423, R430, or R480. The HIS X800GTO IceQII I have been sent uses the R480 graphics core and is actually recognized by the drivers as an ATI Radeon X850 Pro.

Whatever core the card uses, all GTOs share the same specs: 12 pixel pipelines, 6 vertex shader units, and a 400MHz core clockrate with a 490MHz memory clockrate.

Here are the specs on the GTO along with the other cards I am using in the review for comparison:
