The new Gigabyte SINXP1394 is definitely one of the most highly integrated boards of all time. Giving users extreme flexibility in configuring and adding various PCI devices to the system is what Gigabyte does best in the recent months and the SINXP1394 is no exception. The board alone has suppot for as many as eight Ultra ATA-133 and two Serial ATA devices. Without purchasing any other standalone hardware, you can already configure the SINXP1394 as a storage server for either the home or small office environments.
Continuing the unique 'Dual Miracle' design, Gigabyte has once again integrated the Dual Power System into the SINXP1394. With the ability to supply up to 150A of current to the processor, Gigabyte believes that the board will help prolong the user's investment since it is designed to supply (more than) enough power for future high-speed Pentium 4 processors. The question is, how long would Intel extend the current generation of Pentium 4 processors at 533MHz FSB? Well, it doesn't look like it will go any further once Intel introduces processors at 800MHz FSB.
In content creation and office productivity applications, the SINXP1394 was able to deliver pretty good performance scores, even rivalling the 850E and E7205-based motherboards in certain benchmarks. However, when it comes to applications that depend heavily on the AGP subsystem (such as SPECViewPerf and games), the results were somewhat disappointing. In most games, you stand to lose about 3% in performance, but what bothers us most is the performance in applications like SPECViewPerf, where you can expect to lose up to 12% in speed.
While the poor performance in graphics related benchmarks did not put the SINXP1394 in a good position, we think that it's mainly due to the poor AGP implementations in the SiS 655 chipset. The chipset is really beyond Gigabyte's control and if we put that issue aside, we think Gigabyte has done an excellent job in putting some of the best features in a SiS 655-based motherboard. Although not exactly a gamer's ideal chipset choice, the SINXP1394 should please power users who's into overclocking and multimedia/general usage - that's if you have the cash to spare since the DPS feature won't come cheap.
