Well there have been numerous people asking how to distinguish between Brisbane(65nm) and Windsor(90nm) parts of the AMD Athlon X2 Series.
First up a little basics
Windsor Core is 90nm core that is to say the transistor size used is 90nm, there are miliions and millions of transistors in a single processor all of this size.
Brisbane Core is 65nm and is the latest entry from AMD's front. It uses transistor size of 65nm and thus is able to pack more transistors efficiently on a single die.
What does that mean to the end user?

What does that mean to the end user?
1. They consume less power, dissipate less heat
2. Brisbane cores tend overclock way better then Windsor Cores
Due to these advantages and much more it makes sense to get a Brisbane Core processor rather then the Windsor Core for AM2.
Since Old Windsor Core processors are still floating around we must identify a Brisbane Core from the Windsor before purchasing, that is before opening the box.
How to Diffrentiate between Brisbane and Windsor?
Currently Brisbane Core Processors from AMD come in following flavours
1. 3600+
2. 4000+
3. 4400+
4. 4800+
5. 5000+
As reference I'll be using this image, open it and enlarge it to maximum size.
1. Clock Speed : All Brisbane Core Processors except 5000+ have ODD Frequency Speeds, that is
Brisbane Core :
3600+ : 1900 Mhz
4000+ : 2100 Mhz
4400+ : 2300 Mhz
4800+ : 2500 Mhz
5000+ : 2600 Mhz
Notice that all speeds except for 5000+ has odd speeds i.e 1900, 2100 etc.
All equivalent Windsor Processors have even clock speeds which are :
Windsor Core :
3600+ : 2000 Mhz
4000+ : 2200 Mhz
4400+ : 2200 Mhz
4800+ : 2400 Mhz
5000+ : 2600 Mhz
Speed of the processor can be checked on the top of the box as in the image in the top right corner.
2. Cache : Another way to Identify Brisbane Cores is by checking the L2 Cache Size (also on top of box, top right corner in the image). This is not a sure shot method like the previous method as some Windsor Cores also have the same Cache size. I will here mention only those models which have different Cache Size for both the cores.
Brisbane Core :
3600+ : 640+640 KB
4000+ : 640+640 KB
4400+ : 640+640 KB
4800+ : 640+640 KB
Windsor Core :
3600+ : 384+384 KB
4000+ : 1152+1152 KB
4400+ : 1152+1152 KB
4800+ : 1152+1152 KB
As you can see all processors except 5000+ can be identified easily from the above two methods.
3. Product Code :
To identify X2 5000+ as Brisbane or Windsor you need to Check the OPN Code written on the top of the box (at the bottom of the attached image)
The OPN Code for Brisbane 5000+ is :
ADO5000DDBOX
The OPN Code for Windsor 5000+ is :
ADA5000CZBOX
or
ADO5000CZBOX
As you can see, the model no. is mentioned after the first three letters, the object of interest is the next alphabet, which has been bolded here :
For Brisbane Core this letter should be : D
For Windsor Core this letter should be : C
This method can also be used to identify the lower end models of Brisbane Core making this method suitable for identification of all Brisbane Core Processors i.e. 3600+, 4000+, 4400+, 4800+ and finally 5000+.
