Pro Team Computer Corp. is the manufacturer of AZZA main-boards. Incorporated in 1989, Pro Team Computer Corp. started by providing design and testing services to other large main-board manufacturers and has, in the process, developed a core competency in the research and development of main-boards. Being an outwardly focused and customer-driven company, Pro Team Computer Corp. is now focusing on its ability to create a differentiated main-board with enhanced features that give greater value to customers.

The BX chipset was the first platform that officially supported the 100MHz FSB. When it was introduced in 1998 it was considered the top solution in the chip-set arena. Not so long ago, we officially touched the official 133MHz FSB world with Intelís latest Pentiun III CPUís (B, EB). As the BX platform was never meant to run at Speeds beyond 100MHz a new improved chip-set was needed. Or that was what was claimed by Intel anyway. Of course the chip giant (Intel) was already working on a solution. They were also closely working with RAMBUS.inc to adopt RAMBUS memory in their upcoming chip-sets, which was claimed to tremendously boost performance compared to SDRAM.

Intelís latest chip (i820) CAMINO never saw any big success and a simple explanation is available: high memory prices (rambus). The i820 is an interesting performer when running with the fastest RAMBUS memory (PC800) and only with RAMBUS PC-800. Taking a look at the present, there are a few official chips that support the 133MHz FSB. First is the i810e by Intel, unfortunately this chip was targeted for the low cost market as it already comes with an integrated low cost video card, which wonít do the job for the demanding 3D person.

The second 133MHz candidate is VIAíS latest Apollo Pro 133A Chip, which practically features everything the i820 has to offer, the single interesting difference is the use of SDRAM PC-133 memory in place of the High Priced Rambus Memory. The Apollo 133A chip-set is considered today as being the wise 133MHz Solution money can buy. A board featured with the chip is priced somewhat lower than an i820 motherboard. Intel also managed to create a version of the i820 chip-set running on PC-133 SDRAM, unfortunately this didnít end up being a successor in any way since the performance ended up being close to horrible in many cases.

Not too long ago, Tomís Hardware Guide posted the second edition of "The Giga-Battle" article. By taking a closer look at the numbers, we can see the BX chip-set won most of the competition, and in most cases left itís younger brother (i820) w/PC-800 RAMBUS behind, actually way behind. Yes, this means that the BX chip is still a very attractive candidate running at 133MHz FSB. In fact, the BX chip even leads when compared to the VIA APPOLLO 133A PRO platform.

BX is here to stay, for now anyway. Several companies, after analyzing the current CPU and chipset status, got the bright idea on improving their BX based products to meet some of todayís needs. A good example is the implantation of an ATA/66 controller onboard. All of this can be done without making the production costs too high. Azza has a good example of this with their DIB4X motherboard.
