Two Full Featured Radeon 9700 Pros Go Head to Head...

It has been about 5 months since the first round of "Built by ATi" RADEON 9700 Pro boards found their way onto store shelves.  Immediately after the first set of benchmarks and image quality comparisons hit the web, it was clear that ATi had a winner on their hands.  Performance was second to none, and image quality with Anti-Aliasing and Anisotropic filtering enabled was top notch.  OEMs were itching to ship products "Powered by ATi's" latest flagship VPU.  A few companies released cards that were virtually identical to the ATi built products.  However, two companies, Gigabyte and Tyan, have since brought cards to the market that differ slightly from the reference design (at least in appearance).  Tonight on HotHardware, we're going to take a look at Gigabyte's Maya II R9700 Pro and Tyan's Tachyon G9700 Pro.  These two cards have generated quite a buzz in the hardware community...read on and find out why...

The Bundles:






The Gigabyte Maya II R9700 Pro shipped with a very complete assortment of bundled accessories and software.  In addition to the obligatory driver CD, Gigabyte included a full version of Cyberlink PowerDVD 4 XP, probably the best DVD playback software on the market today.  There were also four full version games included, Serious Sam, Rune, Motocross Mania and Heavy Metal F.A.K.K.2.  This hodgepodge may not be the most cutting edge group of games you've ever seen, but they were welcome additions nonetheless.  There were also "lite" versions of two more games, 4x4 Evo and Oni, bundled with the Maya II.  Lastly, Gigabyte included a DVI-to-15 Pin adapter, a composite video cable, an S-Video cable and a Molex power cable splitter as well.

When directly compared to Gigabyte's bundle, Tyan's was a bit more austere, however.  Included with the Tachyon G9700 Pro was a CD that contained drivers and Tyan's custom hardware monitoring software, as well as a copy of Intervideo's very capable WinDVD playback software.  A composite video cable, an S-Video cable, an S-Video-to-RCA adapter, a DVI-to-15 Pin adapter and a Molex power cable splitter were also included.  Overall, Tyan's bundle was good, but it lacked any game software.  Considering the price the Tachyon G9700 Pro commands, and the fact that the vast majority of people buying R300 powered video cards are gamers, we think including a game or two to showcase the hardware would be a good idea.
