SAPPHIRE RADEON X1950 XT
256MB GDDR3 AVIVO REVIEW

"This is a review of the Sapphire Radeon x1950 XT which uses the R580 Core. The Sapphire Radeon x1950 XT will be compared to the Connect3D Radeon x1950 Pro, Sapphire Radeon x1800 GTO, Sapphire Radeon x800 GTO and the Sapphire Radeon x1650 Pro. We have selected a mixture of benchmarks including 3dmark 2005, 3dmark 2006, ATI Double Cross, PowerVR Fable, Rightmark, Shadermark, Doom III, Prey and Quake 4. The Sapphire Radeon X1950 XT brings forth the dawn of a new technological day where games are no longer chained to the limits of the PC hardware!"

COMMENT - "The Sapphire Radeon x1950 XT is clocked at 625 Mhz which is 8% or 50 Mhz higher than the Connect3D Radeon x1950 Pro. The Sapphire Radeon x1650 Pro is clocked only 25 Mhz slower than the Sapphire Radeon x1950 XT which is impressive for a budget video card."

COMMENT - "Core and memory speeds are important but with Pixel Shader intensive games the more Pixel Shaders a video card has the better. The newer Sapphire Radeon x1950 XT has 48 Pixel Shaders and the Connect3D Radeon x1950 Pro has 36. The other video cards only have 12 Pixel Shaders which will be a disadvantage with some software."

COMMENT - "The Sapphire Radeon x1950 XT shows it's power by outperforming the Sapphire Radeon x1800 GTO by 29%, Sapphire Radeon x800 GTO by 46% and the Sapphire Radeon x1650 Pro by 43%. The only slightly negative is that the Sapphire Radeon x1950 XT was only able to beat the Sapphire Radeon x1950 Pro by 7%."
