With the internal clock doubler CPU, it boosts overall system performance between 50 and 70 percent above the original Intel486 DX series. [3] . 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 i486DX2 at 66 MHz (with 33 MHz external bus) was faster than the 486DX-50, overall. More powerful i486 iterations such as the OverDrive and DX4 were less popular (the latter available as an OEM part only), as they came out after Intel had released the next-generation Pentium processor family.

1989 英特尔发布了第一块Socket 1接口的 486DX 处理器，当时的这块CPU的工作频率为 25 MHz。当处理器内含晶体管数为120万个，具备8 KB的L1高速缓存，核心电压为5 V。

Intel 80486DX - 具有FPU的i486。 Intel 80486DX2 - 以2倍 倍频 来运行的 处理器。 Intel 80486SX2 - 与i486DX2相同，但是没有FPU功能。 Intel 80486SL - 低耗电的i486DX，主要用 …

2024年4月3日 · Intel released the 486SX in April 1991 and retroactively created the 486DX to counter AMD’s new 386 clone CPU. The actual difference between the 486 DX and SX has long been a topic of debate. There is a very persistent rumor that Intel had yield problems with the 486, where the processor worked fine except for the math co-processor.

2023年10月18日 · 80486DX2是英特尔1993年发布的处理器，这是一款以2倍倍频开运行的处理器。 TI凭借多年与Cyrix合作的经验，异军突起，自行生产了486DX系列微处理器，这是一款面对oem市场的处理器。 虽然没有技术上的突破，但是在486DX2成为主流后，其DX2-80因为较高的性价比成为当时的主流产品之一。 TI 486DX最高频率达到100MHz，但是从这之后再也没有涉足民用CPU市场。 数码影音爱好者，好用好玩的产品都想体验。 Vx：Uncle7F. 那你快退休了吗？ …

从结构上来说486DX=386DX+387+8KB Cashe，它把80386 CPU与数字协处理器80387、8 KB的超高速缓冲存储器集成在一个芯片上，且支持二级Cashe，它使 CPU 的性能大大提高。在80486内有一条U流水线，用来处理各种指令。

2015年12月13日 · Intel changed the OverDrive processor designation around 1994. A 66 MHz clock-doubled 486DX was now called DX2ODPR66 (rather than ODPR486SX-33). The 66 MHz OverDrives were still mechanically and electrically very similar to their standard OEM brethren, but always came with a heatsink and logo.

Broad I/O functionality including LVCMOS, LVTTL, GTL, PECL, and LVDS. High drive I/O; capability of sinking up to 48 mA with slew rate control, current spike suppression and impedance matching.

Intel 486DX Microprocessor. In 1989, the 32-bit 486DX heralded Intel's fourth generation of microprocessors with two radical innovations: the integration of the floating-point unit (FPU) on the same chip and the addition of an internal write-through 8-Kbyte memory
