Dummy question about /proc/cpuinfo

Perhaps this is a very dummy question but sorry I don't know other place to do it. We just buy a new cluster of Xeon machines but there is something I don't understand and perhaps someone can help me.

The more /proc/cpuinfo produces the following output (just part of it).

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Xeon(R) CPU E5420 @ 2.50GHz
stepping : 6
cpu MHz : 1998.000
cache size : 6144 KB
physical id : 0
siblings : 4
core id : 0
cpu cores : 4

I revise the E5420 specifications and it says that it has 12MB of cache, however only 6MB are reported in the cpuinfo. Can someone help me
to understand this?

Thank you in advance.

Jorge

NAME
cpufreq-set - A small tool which allows to modify cpufreq settings. SYNTAX
cpufreq-set [options] DESCRIPTION
cpufreq-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all the time. OPTIONS
-c --cpu <CPU> number of CPU where cpufreq settings shall be modified. -d --min <FREQ> new minimum CPU frequency the governor may select. -u --max <FREQ> new maximum CPU frequency the governor may select. -g --governor <GOV> new cpufreq governor. -f --freq <FREQ> specific frequency to be set. Requires userspace governor to be available and loaded. -r --related modify all hardware-related CPUs at the same time -h --help Prints out the help screen. REMARKS
Omitting the -c or --cpu argument is equivalent to setting it to zero. The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter except the -c CPU, --cpu CPU parameter. FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre- quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000). On Linux kernels up to 2.6.29, the -r or --related parameter is ignored. FILES
