Matrox announces new Parhelia™-512 GPU
At last, a three headed AGP, OpenGL video card that
delivers performance and features idealy suited for Panoram's
PV Series displays.
Distinct Innovative Features
TripleHead Desktop—For the maximum onscreen real
estate, Parhelia-512 uses a specialized third RAMDAC to support
an ultra-wide rectangular Windows desktop stretched across
three displays to a maximum resolution of 3840 x 1024 @ 32bpp.
Superior Performance
With massive memory bandwidth and a colossal array of
3D processing elements, Parhelia-512 delivers the fastest
2D, Microsoft DirectX® 8, OpenGL 1.3 and DVD performance.
It sustains very high performance even during the rendering
of complex 3D scenes with high polygon counts, FAA-16x antialiasing,
8-sample anisotropic filtering, 10-bit GigaColor Technology,
and deep vertex and pixel shaders. Parhelia-512 pushes the
limits of design and architecture by integrating the following
high fidelity performance technologies:
512-bit GPU
Parhelia-512 is the first 512-bit GPU and the first device
with a true 256-bit wide DDR local memory interface, which
can provide over 20 GB/s of raw memory bandwidth. Forming
the backbone of the rendering and display engine, the 512-bit
architecture and massive memory bandwidth enable Parhelia-512
to sustain the highest performance for the most complex 3D
and 2D applications, even during high resolution, multi-display
computing.
Quad DirectX 9 Vertex Shader Array
Parhelia-512 integrates four Microsoft DirectX 9 compatible
vertex shader units into a single vertex processing array.
Powered by a sophisticated control unit, with deep instruction
and register caches, Parhelia-512 is able to sustain very
high performance levels even when executing complex vertex
shader programs on high-resolution 3D models. In addition,
Parhelia-512 is optimized for OpenGL standard lighting models
and handles these at accelerated rates.
Quad Texturing
Parhelia-512 is the first GPU to enable single-pass quad texturing
with four pixel-per-clock throughput. With the latest generation
of 3D games, and a plethora of future games expected to push
the limits of texturing beyond dual texturing, Parhelia-512
is the only GPU that provides a rendering platform that sustains
performance for cutting-edge graphics applications.
