NEXCOM has developed a brand new product in its history, the Dual Pentium III FC-PGA; VIA Apollo Pro
266 based all-in-one main board with the ATX form factor. A new product family called the NEX series is
created. The NEX 6620A, name of this new product, is the first model to be available.
The major features of the NEX 6620A are as follows:
1. Dual Pentium III FC-PGA architecture with 133 MHZ FSB up to 1 G+Hz CPU clock.
2. Support DDR SDRAM with 4 DIMMs, memory size up to 4 GB.
3. On board built with VGA×1, intel 82559 Ethernet controller×2, PCI based Adaptec AIC 7899 dual channel
Ultra/ 160m.
4. AGP slot×1 for 4×AGP, and 32 bit/ 33 MHz PCI slot×5.
With all above features equipped on board, The NEX 6620A is one of the top performance DP server boards
in the world. So far, it's still the smallest main board with so many features integrated on the standard ATX
form factor. Without any add on cards, the NEX 6620A could out perform most of the server boards because
there are 2x 100 Base TX Ethernet ports and 2x Ultra/ 160m SCSI channels on board. NEX6620A is
particularly suitable for the ISP server applications. A 2U chassis could easily accommodate the NEX 6620A.
For larger server chassis, like the big tower, 5U, 6U, or even 8U rack mounted chassis, the NEX 6620A
could also be applied in these cases that are ATX compatible. The reason to create the ATX server line is
based on the fact that most producers use ATX form factors. With rigidly complying with ATX specifications,
the NEX 6620A could be applied in any case requiring the top server performance, as long as it's ATX
compatible.
The NEX 6620A could also be positioned as the top performing workstation. With the on board AGP, the 4X
AGP slot reserved for any next generation 3D VGA/ Video accelerator cards, the NEX 6620A could out
perform any other DP architectures. Again, the standard ATX form factor is the greatest advantage of the
NEX 6620A for any workstation chassis, and it will help a lot for the NEX 6620A to be widely accepted by the
power users in the compute-intensive workstation applications or the I/O intensive server applications.
