ST ST486DX2-80GS Processor - 80486 80Mhz Frequency 40Mhz FSB Microprocessor Simple Type: Processor
The SGS-THOMSON ST486DX/DX2 5 volt CPUs are advanced 486DX/DX2 compatible processors. These CPUs incorporate an on-chip 8KByte write-back cache and an integrated math coprocessor. The on-chipwrite-back cache allowsup to 15%higher performance by eliminating unnecessary external write cycles. On traditional write-through CPUs, these external write cycles can create bus bottlenecks affecting system wide performance. The integrated floating point unit, improves performance up to10% over the 80486DXas measured using Power Meter Whetstone test. These processors are designed to meet the power management requirements in the newest generation of low-power desktops and notebooks. Power is saved by taking advantage of advanced power management features such as static circuitry, SMM, and automatic FPU power-down. Fast entry and exit of SMM allows frequent use of the SMMfeature without noticeable performance degradation. This CPU family maintains compatibility with the installed base of x86 software and provides essential socket compatibility with the 486DX/DX2.
