Suggest you download (Free) the tiny program, CPU-Z, from CPUID.comhttp://www.cpuid.com/softwares/cpu-z.html
Bear in mind that the example shown on the CPU-Z page, is for a newer Intel Core i7 model.
These processors do Not use a Front Side Bus. (FSB)
Where it states QPI is Quick Point Interconnect.
For the older processors this will state Rated FSB instead.
FSB is Front Side Bus.
Tells you what Frequency Rate ('Speed') that the processor FSB, is operating at THAT moment.
(All info is Real Time. Watch the Core Speed change)
Looking at the GUI example on the CPU-Z page, observe the tab that states CPU.
When the program is first opened, the Processor (CPU) tab is automatically opened.
Here you can see very detailed information on the Processor.
Main things to look at are;
1) Name: Manufacturer name and the Model Number
2) Code Name: This name will help you differentiate what processor you are looking at. One of the things that is specific TO THAT processor.
3) Package: Essentially tells you the processor socket that is used.
4) Core Voltage: The optimum voltage the Processor will operate on.
It is DC voltage.
There is a voltage Range the processor will operate in, but the range is VERY SMALL.
Depends on the processor, but 2/10ths above, or 2/10ths below, is an average example ( .2 )
5) Rated FSB:
This part of what you need to know, IF you are looking at upgrading the Processor.
The rest of what you need to know, is what Motherboard Chipset is used.
Chip and Chipset are slang terms for I.C.
The terms are used alternatively, as either Chip, or Chipset, also.
For example, the motherboard chipset is actually two Chipsets.
The Northbridge chip, and the Southbridge chip.
(For the technology used by the motherboard of the IBM Aptiva)
The Northbridge chip handles the Faster capabilities of a computer.
The Processor, Ram Memory, and High-speed graphics.
High-speed graphics being the AGP, or PCI-Express technology.
A graphics card in a PCI slot, or using Integrated Graphics, is Not
The Southbridge chip handles the Slower capabilities of a computer.
1) Anything to do with the PCI Bus.
(Such as a graphics card installed in a PCI slot )
2) Same with the IDE Bus
3) SATA bus
4) USB bus
6) Audio (Sound)http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg
[ CPU stands for Central Processing Unit. Another term used is Microprocessor, or simply Processor, for short ]
Clicking on the Mainboard tab, will show what the motherboard chipset is. (Mainboard is proper computer speak for Motherboard)http://en.wikipedia.org/wiki/IBM_Aptiva
Now then, what Series is it, and what Machine Type?
