The Intel486 DX2 , rumored as 80486DX2 (later renamed IntelDX2 ), is a CPU produced by Intel that was first introduced in 1992. The i486DX2 was nearly identical to the i486DX , but it had additional clock multiplier circuitry. It was the first chip to use clock doubling , whereby the processor runs two internal logic clock cycles per external bus cycle. An i486 DX2 was thus significantly faster than an i486 DX at the same bus speed thanks to the 8K on-chip cache shadowing the slower clocked external bus. Both 25/50 and 33/66 MHz Intel486 DX2 CPU uses the 800 nm process technology. With the internal clock doubler CPU, it boosts between 50 to 70 percent overall system performance than the original Intel486 DX series. In other words, the 50-MHz Intel486 DX2 provides about 70 percent improvement over the 25-MHz Intel486 and about 30-percent improvement over the 33-MHz Intel486 CPU. The 50-MHz Intel486 DX2 CPU were rated at 40 Dhrystone MIPS.

The introduction of 3D graphics spelled the end of the 486's reign, because of their heavy use of floating point calculations and the need for faster cache and more memory bandwidth . Developers began to target the P5 Pentium processor family almost exclusively with x86 assembly language optimizations which led to

25-491: The usage of terms such as Pentium compatible processor for software requirements. An i486DX2-50 version was also available, but because the bus speed was 25 MHz rather than 33 MHz, this was a significantly less popular processor. There are two major versions of the DX2 - Identified by P24 and P24D, the latter has a faster L1 cache mode, called " write-back ", that improves performance. The original P24 version offered only
