The i486DX2 at 66 MHz (with 33 MHz external bus) was faster than the 486DX-50, overall. More powerful i486 iterations such as the OverDrive and DX4 were less popular (the latter available as an OEM part only), as they came out after Intel had released the next-generation Pentium processor family.

The 486DX has an integrated floating point unit (FPU) which speeds up applications like CAD or spreadsheets tremendously. In most main-stream applications and games that run fine on a 486, the FPU doesn't really come into play.

Dec 19, 2024 · Opening it up revealed a 486DX-33 with 4MB in 30 pin SIMMs and 128KB of cache on a GMB-486UNP mainboard (UniChip chipset, 7 ISA slots, 3 with VLB.) There was also a Cirrus Logic CLB-5426 graphics card (VLB) and a Goldstar Multi-IO card (16 bit ISA).

Aug 15, 2009 · Intel 486 featured much faster bus transfers - 1 CPU cycle as opposed to two or more CPU cycles for the 80386 bus. Floating-point unit was integrated into 80486DX CPUs. This eliminated delay in communications between the CPU and FPU. Furthermore, all floating-point instructions were optimized - they required fewer number of CPU cycles to execute.

This AST Advantage 486/33 desktop computer is a great find for vintage computing enthusiasts. With its classic design and retro feel, it's sure to bring back nostalgic memories. This computer is in great working order and has been well-maintained over the years.

Jun 24, 2014 · Below are some pictures of my CMOS setup and the best settings I could achieve to ensure a stable setup (under DOS) for my 486DX 50 MHz. With the 486DX 33 MHz, I was able to set everything to the fastest settings and shortest wait states but, still keeping Local Bus Ready at "Synchronize".
