This chip, which is based on the {{intel|microarchitectures/80486|80486 microarchitecture}}, had a clock multiplier of x2, x2.5, and x3 with a max operating frequency of 75 MHz, three times the bus frequency. Like the original i486DX, this chip implemented the {{intel|80387}} [[FPU]] on-die and incorporated {{intel|System Management Mode}} (SMM). The DX4 series had twice as much cache as the older processors. |
