In October of 2005, ATI announced the Radeon X1800 XT, with wide availability set for November 5.
A short time later, in either early December or late November, ATIs darling finally arrived.
With the launch of the Radeon X1900 family, however, the X1800 will end up having a life span slightly longer than a fruit fly.
ATIs new X1900 family includes the X1900 XTX, the X1900 XT, the X1900 Crossfire, and the X1900 All In Wonder.

Radeon X1900 Series Of Cards
In a new turn of events, the typically fashionably late All In Wonder series of cards will launch concurrently with the rest of the X1900 lineup.

Whereas the X1800 has 16 pixel pipelines and 16 pixel shader processors, the X1900 XTX comes with 16 pixel pipelines and an astounding (and baffling) 48 pixel shader processors.

All these numbers boil down to a card thats very fast, in specific ways.
The X1900 series has the same ring bus memory controller found in the X1800, and it is designed to minimize latency and scale up compatibility with the fastest graphics memory to date.
The chip uses eight 32-bit memory controllers, instead of four 64-bit controllers, to increase memory accesses.
ATI has also switched to a fully associative cache to increase memory hit rates.
All of these memory changes help to improve frame rate performance at high-resolution, high-image-quality settings where memory performance becomes the bottleneck.
Improvements in hidden surface removal by culling out pixels not in view will also increase performance.
Over the years, ATI noticed that increasing all portions of the GPU equally would result in wasted processing power.
ATI noticed that in current games, video cards perform five times as many arithmetic shader operations as they do texture shader operations.
As a result, many of the improvements (namely the 48 pixel shader processors) to the X1900 come in the form of vastly improved arithmetic shader operations.
Nvidias GeForce 7800 series can render Shader Model 3.0 and HDR, but in certain games, you cannot enable antialiasing while doing so.
The Radeon X1900 cards performed exceedingly well in our 3D graphics tests.
