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.

Cache[edit]

Main article: 80486 § Cache

The i486dx4-100 was offered with two cache policies. Models that came with a write-back cache were marked by an "&EW" identifier. Models that came with a write-through policy were marked by "&E".
