I have been using CPU Z since last 2-3 years and so far nothing like that came up.
CPU Z is very reliable in my opinion.
be that as it may i have seen instances of cpu-z reading cpus wrong. for example... someone unlocked the hidden cores on an athlon II x2 and it was read by cpu-z as a phenom II x4... the only thing is that this is impossible since the athlon II's didn't have an L3 cache and the phenom IIs did.
I know that this isn't the same situation but you have 2 different sources giving you different cpu info. one of those sources is wrong.
So do you or anyone else know which CPU have I exactly got? I bought it after thinking it has got an i3 but since it states CPU name as i7 (And the fun thing is that both the CPUs are are exact same clock speeds), I think Dell guys installed an i7 instead of i3.
Okay so now the problem is that both i7 and i3 models listed above have same number of physical and virtual cores too (Both are dual core with Hyper-Threading).
Still not getting to know it ... It could be either one of those ...
As far as I know machines do not have IQ so they can not think and list any very similar processor out there in info and make people think they have an i7 out there.
hmmm I thought for sure that i7s were quad cores... my bad on that one. simon's right, a quick benchmark would tell you what you have beyond a shadow of a doubt. look up the benchmarks for the i7 and compare your results.
