 
 <prompt> Which one come out later, the PowerBook 500 or the first 486-powered IBM compatible laptops? Given the previous question, write a context wey contain the answer. E fit be 1 - 20 sentences. Context: <response>: Intel bin try but e no fit convince Apple to move Macintosh platform go Intel chips. Apple come reason say Intel CISC (Complex Instruction Set Computer) architecture no fit compete against RISC (Reduced Instruction Set Computer) processors. While Motorola 68040 get di same features as Intel 80486 and fit outperform Intel chip well well on clock-for-clock basis, di 486 fit clock pass well well without overheating wahala, especially di clock-doubled i486DX2 wey dey run di CPU logic at twice di external bus speed, wey give IBM compatible systems wey get am significant performance pass their Macintosh equivalents. Apple product design and engineering sef no help matters as dem restrict di use of '040 to their expensive Quadras for some time while 486 dey available to OEMs and enthusiasts wey dey put together their own machines. For late 1991, as di higher-end Macintosh desktop lineup dey move to '040, Apple no fit offer '040 for their top-of-the-line PowerBooks until early 1994 with PowerBook 500 series, several years after di first 486-powered IBM compatible laptops enter market wey cost Apple plenty sales. For 1993 Intel bring out Pentium processors as successor to 486, while Motorola 68050 no ever come out, wey leave Macintosh platform one generation behind IBM compatibles for di latest CPU technology. For 1994, Apple comot from Motorola CPUs for RISC PowerPC architecture wey AIM alliance of Apple Computer, IBM, and Motorola develop. Power Macintosh line, wey be di first to use di new chips, show say e dey successful well well, with over one million PowerPC units wey dem sell for nine months. However, for di long run, rejecting Intel for PowerPC na mistake as di commoditization of Intel-architecture chips mean say Apple no fit compete on price against "the Dells of the world".
