it is not a problem, but a matter of reporting. I have the same Q6600 as you.

 

Hardware Overview:

 

Model Name: Mac

Model Identifier: MacPro3,1

Processor Name: Intel® Core2 Quad CPU Q6600 @

Processor Speed: 2.4 GHz

Total Number Of Cores: 4

L2 Cache (per processor): 4 MB

CPU Features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON DSCPL VMX EST TM2 SSSE3 CX16 TPR PDCM

Memory: 6 GB

Bus Speed: 1.07 GHz

Boot ROM Version: Hack.88Z.int.0sh.061193037 (Award Software International, Inc.)

Serial Number: CK157KMHK5B

 

 

Pay attention to the L2 line: it says PER PROCESSOR. Well Q6600 are in fact two dual core silicon dies bonded together inside one capsule. One silicon die counts as a processor, and has a L2 cache of 4MB. Look up retailers for Q6600 and you'll see L2 reported as 2x4MB, not 8MB. The L2 cache is not unified per capsule, but per die ("processor" for the purpose of reporting above). Mystery solved! Leopard didn't eat your cache!

 

Future Intel CPUs like Nehalem will be true (quad/octo) cores (on the same die) and will have 8 MB or more of L2 unified cache.
