The ATI Radeon X1900 XT video card uses advanced AMD technology to bring you the best in graphics for a more immersive experience. Experience the thrill of graphics that are so sharp and detailed, you feel as though you're truly a part of the action.And in single-card mode, at least, the Radeon X1900 XTX beat the GeForce 7900 GTX at every resolution, although by only a small margin. test is the most telling in our 3D suite because it's the most demanding DirectX-based game, which is a much more common design language, or API, than the Doom 3 engine's Open GL. In recent history, ATI's cards have traditionally fared well in single-card tests when compared to their Nvidia equivalents, and the Radeon X1900 XTX is no different when matched up against the GeForce 7900 GTX. GeForce cards can only do one or the other at a time. The Elder Scrolls IV: Oblivion is one game where you can do it (by way of an unofficial driver update called the 'Chuck patch'), and there are a handful of others. In the few games that feature high dynamic range lighting (that is, extreme shadows and extreme lighting that shines with accurate cloudiness from its source), ATI's cards let you enable that feature and antialiasing (removes the jaggedness from diagonal 3D lines) at the same time. The problem is, they're mostly theoretical. It's best to accept it, do research, acquire the power supply you need (which will vary based on the CPU and other hardware in your system), and move on.ĪTI's entire X1000 series maintains an advantage over Nvidia's GeForce cards in that they can perform some advanced graphics-quality tricks simultaneously that Nvidia's cards can do only one at a time. These specs are no different than those required by comparable Nvidia configurations. If you're building a high-end PC, you should know by now that it will require lots of power. A single Radeon 1900 XTX requires a 450-watt power supply, while a CrossFire configuration needs at least a 550-watt power supply (and ATI recommends '38 amps on the 12-volt rail ' check your PSU's specs to see if yours fits the bill). We've also accepted that most 3D cards now require a direct connection to your PC power supply. We'll merely state as fact that the Radeon X1900 XTX is bulky due to the large fan and cooling assembly it occupies one x16 PCI Express lot, while blocking access to the x1 or x4 PCI Express slot next to it. We've come to terms with the modern high-end 3D card occupying one slot while blocking an additional expansion slot, so we'll stop complaining about it. The Lost Coast demo implements more-advanced 3D features than the original Half-Life 2 graphics engine. Editor's note: When this review was first published, the Half-Life 2: Lost Coast demo chart was labeled simply Half-Life 2.
