Intel Pentium Overdrive For 486

Historia

This Pentium OverDrives are Intel Pentium processors for 486 Socket 3 and Socket 2 motherboards, provided as a means to give a Pentium performance-level upgrade option for owners of 486 computer systems. It was however criticised for being more expensive and slower than competing CPU-upgrade options such as the AMD Am5x86 and Cyrix 5x86, and being too late to the market. Mainboard compatibility was also a problem, it turned out that many boards didnt support this new chip. To perform properly, the Pentium OverDrive was dependent on a high amount of secondary cache ram being present on the motherboard; without it the chip was only a trivial amount faster than a DX4.
