Determine Processor Type and Cores

Posted on 2006-11-11

Last Modified: 2013-12-03

I've got a machine I'd like to determine exactly what is inside it.  Its unbranded.

From the control panel I can see Windows is reporting:

2.80 Ghz Intel(R) Xeon(TM) CPU 3.00Ghz
ACPI Multiprocessor PC

And from the Task Manager there are four separate Processor Speed Graphs..

Which processor do you think I have?


If it is a dual processor machine and then each has dual cores?  Is that why there are four separate Processor Speed Graphs?  Or has Windows read things wrong?

WCPUID (CPU memory an motherboard info)

OR If you are getting messed about give this a try (I've not used it though)

Yeah the WCPIUD rocks!  

1) Although it needed to download the latest identities before it knew my CPU - fair enough


2) H Oda's email no longer works - it bounced back to me, and there's no contact form on his website....

But nevertheless it came up with this.....

So where does that leave me?  I'm interested to know which CPU I have from the wikipedia list.

I think the version of CPUID you are using is too old to be accurate.  It is saying the cpu is running at 2.8 when it is a 3.0 processor, and it says the L2 cache is 128K, which doesn't exist.  The L2 cache and cpu voltage should be enough to uniquely identify the processor.  Belarc should be more up-to-date, or use andyalder's suggestion of the Intel tool.

OK This is what the INTEL util came up with.

Intel(R) Processor Identification Utility
Version: 3.1.20060901
Time Stamp: 2006/11/12 19:57:09
Number of processors in system: 2
Current processor: #2
Processor Name: Intel(R) Xeon(TM) CPU 3.00GHz
Type: 0
Family: F
Model: 4
Stepping: A
Revision: 0
L1 Trace Cache: 12 Kµops
L1 Data Cache: 16 KB
L2 Cache: 2 MB
L3 Cache: None
Packaging: 604 pin µPGA
MMX(TM): Yes
SIMD2: Yes
SIMD3: Yes
Enhanced Halt State: No
Execute Disable Bit: No
Hyper-Threading Technology: Yes
Intel(R) Extended Memory 64 Technology: Yes
Intel(R) Virtualization Technology: No
Expected Processor Frequency: 3.0 GHz
Reported Processor Frequency: 2.74 GHz
Expected System Bus Frequency: 800 MHz
Reported System Bus Frequency: 784 MHz

Which processor is this in the Wikipedia article?

Can anyone explain the 4 digital levels in Task Manager?

I would say it's the retail package Intel refers to as Active - BX80546KG3000FA Passive - BX80546KG3000FP 1U - BX80546KG3000FU or the OEM package RK80546KG0802M on Intel's page: http://www.intel.com/support/processors/xeon/sb/CS-009348.htm

That would be the "Irwindale" (standard-voltage, 90 nm) with part number RK80546KG0802M on the Wikipedia article.  You have 4 graphs because you have two cpus and each cpu is hyperthreading, so the system "sees" 4 processors.
