Subject: about interlagos
Date: Fri, 15 Jun 2012 23:41:33 -0700 (PDT) [thread overview]
Message-ID: <1339828893.59679.YahooMailNeo@web111722.mail.gq1.yahoo.com> (raw)
There are three opteron processors with the cpuid that I paste below:
model name : AMD Opteron(tm) Processor 6136 (magny core, 8)
cpu MHz : 800.000
cache size : 512 KB
bogomips : 4800.20
model name : AMD Opteron(tm) Processor 6174 (magny core, 12)
cpu MHz : 800.000
cache size : 512 KB
bogomips : 4400.13
model name : AMD Opteron(TM) Processor 6274 (interlagos, 16)
cpu MHz : 1400.000
cache size : 2048 KB
bogomips : 4399.97
As you can see, although interlagos is the newest one which has higher cpu
clock rate and higher cache size, the bogomips of interlagos is the lowest!
I read that bogomips is not a true measurement, but it senses as a speed meter.
Any idea?
