What type of i486 CPU are you inquiring about?

The following is from the Intel486 DX2 Microprocessor Performance Brief (order
number 241254-001):

On a 50MHz i486DX CPU system with 32MB of RAM and 256KB of cache:

Dhrystone1.1 VAX MIPS: 41.4
Dhrystone2.1 VAX MIPS: 39.4

Linpack MFLOPS (single precision): 2.7
Linpack MFLOPS (double precision): 2.4

On a 33MHz i486DX CPU system with 32MB of RAM and 256KB of cache:

Dhrystone1.1 VAX MIPS: 27.6
Dhrystone2.1 VAX MIPS: 26.3

Linpack MFLOPS (single precision): 1.8
Linpack MFLOPS (double precision): 1.6

--------------------------------------------------

From the SPEC Newsletter:

On a 50MHz i486DX CPU system with 64MB of RAM and a 256KB cache:

SPECint92: 30.1
SPECfp92: 14.0
