The benchmark results are very satisfying. This latest TX chipset board now officially supports up to 83 MHz bus speed. If this board matures some time, it can be counted to the very best, since it is the successor of the 565. The performance at 83 MHz was really fast under Windows NT. It features a real variety of external frequencies. Starting at 50 MHz up to the already said 83 MHz. The BF2 jumper function was integrated as well, so you will be able to run future CPU at a maximum multiplier of x5.5. The passive voltage regulators were all changed to switching regulators without any coolers; this looks like good work.

This board is the only one equipped with AMD's 640 chipset, which corresponds to VIA's Apollo VP2. The board features 1 MB L2 Cache (2 banks), external frequencies up to 83 MHz, 3 ISA / 4 PCI slots, integrated PS/2 mouse connector (just few cases have the corresponding hole right beside the keyboard connector, the final revision does not have it any longer) and ATX power connector as well. You may use up to 3 DIMMs or 4 PS/2 modules. Dip switches would have been nice, nevertheless the jumpers are well documented. Performance is outstanding, except with the Intel CPU.
