Athlon 1.3 Ghz/200 Mhz in a Gigabyte 7ZX mb with 256
MB of 133 MHz SDRAM
SUSE Linux 7.1 ( gcc version 2.95.2 19991024
(release) )
I compared these two
using the STREAM benchmark (compiled with gcc -O)
* Program: Stream
* Programmer: Joe R. Zagar
* Revision: 4.0-BETA,
* Original code developed by John D. McCalpin
Array size =
8000000, Offset = 0
Total memory
required = 183.1 MB.
Each test is run 10
times, but only
the *best* time for
each is used.
Results:
SDRAM

Your clock
granularity/precision appears to be 9999 microseconds.
Each test below will
take on the order of 259999 microseconds.
