386 performance vs 486It also helped that a fast 386 could keep pace with the slowest 486s. The 40 MHz version of the Am386 enjoyed an especially long shelf life as a value CPU. The 486 was more efficient than the 386 but it wasn’t twice as efficient, so a 40 MHz 386 was faster than a 20 MHz Intel 486SX, and roughly comparable to a 25 MHz 486SX. It also held the additional advantage of taking an external math coprocessor. Part of the point of the 486 was the integrated math coprocessor improved performance, but an external math coprocessor was faster than none. So while a 40 MHz 386 plus a 40 MHz 387 wasn’t as fast as a full 486DX at 25 MHz, depending on whose FPU you used, you could get 75-90 percent of the performance at less than 75 percent of the price.

但就在市场沉浸在单边上涨幻象中时，随着G7商讨释放原油储备的消息释出，国际有机应声下跌，更关键的是没东时间3月9日，美国总统特朗普表示，伊朗战争已基本结束。受此消息影響，原油短线下跌14美元，WTI原油日内振幅达41.95%。，这一点在新收录的资料中也有详细论述
