Introduction
The next contender in our ongoing ATI Radeon X1800 XT reviews comes from a brand that should be no stranger to any hardware enthusiast. A major manufacturer of motherboards, video cards and other components, Gigabyte is one of those established names that we find cropping up often when it comes to discussions about hardware. Its version of the Radeon X1800 XT 512MB testifies to its verve and expertise, as it is one of the few selected partners that has the blessings from ATI, an unprecedented move by the chipmaker, to overclock its Radeon X1800 XT 512MB. The result is the Gigabyte GV-RX18T512V-B Turbo Force Edition (Gigabyte GV-RX18T512V-B Turbo for short in this article). Despite its nondescript appearance and stock cooler, this card is clocked at 700/1600MHz DDR, the 'standard' overclocked frequencies for the Radeon X1800 XT 512MB. Before we delve into the details, here are the rest of its technical specifications:
The GV-RX18T512V-B Turbo Force Edition - Gigabyte's long model name for its overclocked Radeon X1800 XT 512MB. |
