How many penguins you see?


I bought recently ThinkPad X201 using i5-520M processor.

According to https://www.thinkwiki.org/wiki/Category:X201 my machine uses Intel® Core™ i5-520M (Dual-core, 2.4GHz, 3MB L2) processor.

Meanwhile the command cat /proc/cpuinfo displays four entries for this processor:

Code:
model name : Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz
Moreover the command htop displays four entries for CPU as well.

Last but not least during the startup procedures I see four penguins.

So my question is: how many cores uses i5-520M processor: two (according to ThinkWiki) or four (according to /proc/cpuinfo, htop, and startup procedures).

Maybe I missed something: forgive me my ignorance and just reply to my question.

from the specs at intel.com:
# of Cores 2
# of Threads 4

Not sure this answers your question...

Tank you very much!

scasey simply replied my question and camorri gave me an exhaustive reply.

I feel lucky now and – at the same time – about 0.000001% less ignorant than before.
