The 486 Upgrade CPU Showdown!

Although no one disputes that the “Pentium Overdrive for 486 Systems” was a great performing chip, it may not have been the best choice for everyone. And it was certainly not the only choice when it came to pushing the 486 platform to its limits. Today, I’ll be pitting the Pentium Overdrive up against two very formidable competitors - the AMD Am5x86 and the Cyrix 5x86. To make things even more interesting, I’ll be overclocking all three chips as well. The results may surprise you!
