Pentium OverDrive是一种供旧有使用Intel 80486处理器电脑升级用的处理器。OverDrive系列具有兼容上一代系统的脚位与新的运算核心，兼容于Intel 80486的Socket 2脚位，但采用P5 Pentium核心。但自从低价电脑流行以来，此一产品线已淡出市场。因为电脑通常都直接整部全新购买，无需借由这种方式升级。

The Pentium OverDrive was a microprocessor marketing brand name used by Intel, to cover a variety of consumer upgrade products sold in the mid-1990s. It was originally released for 486 motherboards, and later some Pentium sockets. Intel dropped the brand, as it failed to appeal to corporate buyers, and discouraged new system sales.
