The Triton I chipset (official name 82430FX) consists of 4 chips: one 82437FX TSC (Triton Sysetm Controller), two 82438FX TDP (Triton Data Path), and one 82371FB PIIX (PCI IDE Xcellerator). It supports PB Cache, EDO DRAM, and a maximum PCI and memory burst data transfer rate of 100 megabytes per second.
There are also Moble Triton (82430MX), Triton II (82430HX), and the Triton VX (82430VX) chip sets.
