Template:mpu i486DX4-100 was a fourth-generation x86 microprocessor introduced by Intel in 1994. This chip, which is based on the 80486 microarchitecture, had a clock multiplier of x2, x2.5, and x3 with a max operating frequency of 100 MHz, three times the bus frequency. Like the original i486DX, this chip implemented the 80387 FPU on-die and incorporated System Management Mode (SMM). The DX4 series had twice as much cache space as the older processors.
