I should point out that my PIII is in a laptop. I don't know if it's a
so-called mobile Pentium or not. /proc/cpuinfo reports:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 8
model name : Pentium III (Coppermine)
stepping : 1
cpu MHz : 451.030
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse
bogomips : 897.84
It also has separate 16KB L1 I and D caches. From what I was able to glean
from a quick glance at a Katmai vs. Coppermine article, the Coppermine's L2
cache is full-speed, on-chip, with a 256-bit wide connection and 8-way set
associative cache.
Does any of that help explain why my results are similar to Tim's?
