The Volari V3XT is built using XGI's XG42 processor. The XG42 features two pixel pipelines and 1 Vertex engine. The stock clock frequency is 250MHz for the GPU and just 200MHz for the memory, resulting in a fill rate of 0.5Gp/s and memory bandwidth equal to 3,200 MB/s.

Even though the Volari V3XT is a budget graphics card, it is anything but featureless. Surprisingly, it fully supports DirectX 9.0 and not in the way the 9200 does (just DX9 compatible) but can render all the impressive DX9 effects. However, the performance is exceptionally slow and you'll notice it in our first few benchmarks.

Here's a table containing some of the cards features as provided by XGI:

TruShader 2.1 Engine
Volari V3XT processors employ XGI's next generation TruShader 2.1 Engine, taking vertex and pixel shading to a new level of realism. Combine this with built-in DirectX® 9 programmability and 3D environments now come alive with cinematic realism and movie-studio quality effects.
BroadBahn Memory Architecture
Volari V3XT processors take advantage of XGI's proprietary BroadBahn Memory Architecture, moving a staggering amount of data between the processor and graphics board memory.
Cipher Video Processor
Volari V3XT supplies the advanced de-interlacing technology. Video files play with a smooth, flicker-free and fluid motion that amazes even industry professionals.
ControlDeck
ControlDeck Software of Volari V3XT supplies a single interface. Users can manage powerful software programs including DesktopPlus, Rotech, Navigator and so on.
