Tyan announced their intention to start shipping two new mainboards: Trinity KT-A (S2390B) and Trinity 450 (S2507S) in the near future.
The first board is a standard solution based on VIA KT133A chipset and looks very much like the already familiar Trinity KT (S2390). The differences between S2390B and S2390 are quite evident: the new board supports 266MHz FSB (VT8363 North Bridge) and ATA/100 (VT82C686B South Bridge). All other specs remained the same as by the previous model: ATX form-factor, 3 DIMM slots for PC100/PC133 SDRAM (max. 1.5GB), 6 PCI slots, 1 ISA slot (shared with 1 PCI), 1 AGP 4x slot.
The second mainboard seemed to us a bit more interesting. The engineers borrowed the design of this board from the dual-processor Tiger 230. Even the model numbers of the two pieces are close: S2507S (single-processor) and S2507D (dual-processor).
As far as we understand, this is the first case when the dual- and the single-processor mainboards feature the same design. At least we can’t now think of any analogue even by other manufacturers.
As a result, the specs of the two board are identical (except for the number of supported CPUs, of course): ATX form-factor, VT82C694X North Bridge, 4 DIMM slots for up to 2GB PC100/PC133 SDRAM, 5 PCI slots, 1 AGP 4x slot, ATA/100 (VT82C686B South Bridge), etc.
The only "but" is the empty spot intended for the second processor socket, which makes the mainboard look a bit weird. But it doesn’t matter that much actually, since this is a cheap and high-quality solution :-)
