Essentially an Intel 486DX microprocessor with a 16 kilobyte on-chip cache.

The DX4 is the fastest member of the Intel 486 family. 75 and 100MHz versions are available. At an iCOMP index rating of 435, the 100 MHz DX4 performs up to 50% faster than the 66 MHz Intel DX2. The DX4's clock multiplier allows the processor to run three times faster than the system clock. This performance is achieved in part by a 16K on-chip cache (double that of the other 486s). The DX4 has an integrated floating point unit.

Like the other 486s, the DX4 achieves performance through a RISC integer core that executes frequently used instructions in a single clock cycle (the Pentium's can execute multiple instructions in a single clock cycle).

Low power consumption has been achieved with SL Technology and a 0.6 micron manufacturing process, giving 1.6 million transistors on a single chip operating at only 3.3 Volts.

"IntelDX4" is the entire name, the "486" has been dropped and I am assured that there is no space in the same.

(TAIS) has made available one of the first notebook computers implementing the new 75MHz SL Enhanced IntelDX4 processor and an unprecedented 500MB hard disk drive.
The new SL Enhanced IntelDX4 processor, provides high-speed information processing and 32-bit architecture which translates to a 75 percent faster data transfer rate when compared to the i486DX2/40 and a 38 percent faster rate than that of the i486DX2/50.
With its 3.3-volt operating and built-in SL Enhanced technology, the IntelDX4 processor consumes less than half the power of the fastest 5-volt Intel486 processor.
