[comp.sys.ibm.pc] Effect of cache on system speed

leech@threonine.cs.unc.edu (12/03/88)

    Any opinions or insights into which would be faster as a
single-user Unix machine? The ubiquitous Norton SI seems useless for
this type of comparison.

    - 20 MHz 80386, 100 ns memory, AMI write-through cache.
    - 25 MHz 80386, 70 ns memory, no cache (not sure if it's
	interleaved or page mode, though).

    Thanks!

    What is it useful for ?   Other than marketing ?

    Probably like GREs and SATs - useful only for measuring itself.
