Features of the Tyan Tachyon G9600 Pro


Package and Contents



Tyan uses a rather compact box for the 9600 Pro, basically the exact same as the 9500 Pro, which suggests more towards the budget with not too many bells and whistles. One noteworthy feature is that Tyan prints the core and memory speed on the front of the box so you know how fast you card is running before you buy it. On the 9600 Pro, the core is specified at 400MHz with a memory speed of 600MHz.


The card comes with the standard DVI, VGA, and TV-Out connectors. There is a Tachyon Graphics Monitor manual included as well as a Tachyon Graphics Line quick installation guide. They even have a complete user's guide. The CD includes Catalyst Driver version 3.2 and control panel along with DirectX 8.1b. WinDVD 4.0 is also included on the CD. A power cable is also provided if you need to split power off from a device for this card.


The Card and Core



The design of the Tachyon 9600 Pro is almost identical to that of the ATI Radeon 9600 Pro PCB, Tyan changes only one thing; the PCB color - a 4-layer dark blue PCB with a light blue Heatsink and fan combination.



ATI's replacement for the 9500 VPU is the new 9600 and 9600 Pro. This VPU differs slightly in internal features compared to the 9500 Pro. These include the following:


- 4 parallel rendering pipelines
- 2 parallel geometry engines
- 128-bit DDR memory interface
- AGP 8X support


Programmable pixel and vertex shaders
16 textures per pass
Pixel shaders up to 160 instructions with 128-bit floating point precision
Vertex shaders up to 1024 instructions with flow control
Multiple render target support
Shadow volume rendering acceleration
High precision 10-bit per channel frame buffer support
Supports DirectX 9.0 and the latest version of OpenGL


2x/4x/6x full scene anti-aliasing modes
Adaptive algorithm with programmable sample patterns
2x/4x/8x/16x anisotropic filtering modes
Adaptive algorithm with bi-linear (performance) and tri-linear (quality) options


Lossless Z-Buffer compression (up to 24:1)
Fast Z-Buffer Clear


2nd generation N-Patch higher order surface support
Discrete and continuous tessellation levels per polygon
Displacement mapping


Seamless integration of pixel shaders with video
FULLSTREAM™ video de-blocking technology
Noise removal filtering for captured video
MPEG-2 decoding with motion compensation, iDCT and color space conversion
All-format DTV/HDTV decoding
YPrPb component output*
Adaptive de-interlacing and frame rate conversion
Dual integrated display controllers
Dual integrated 10-bit per channel 400 MHz DACs
Integrated 165 MHz TMDS transmitter (DVI 1.0 compliant)
Integrated TV Output support up to 1024x768 resolution
Optimized for Pentium 4 SSE2 and AMD Athlon™ 3Dnow!
PC 2002 compliant


As we can see, there are a few minor differences in technical specifications. The most notable is the look and feel of the core. First off, the die shim that was on the 9500 and 9700 series that caused some cooling issues with 3rd party coolers has been removed. This now allows for direct cooling to the die of the VPU. The core speed has been increased from 300MHz over the 9500 to 400MHz of the 9600 Pro.
