Good day. What I would like to clarify first is Package Size and Sockets Supported that I can see in description of Intel processors like this one:
When trying to ensure compatibility between motherboard's socket and Intel processor, what I am to pay attention to? What is difference between Package Size and Sockets Supported?
I also often see that not exact description of socket types is given in some descriptions. For example, socket PPGA988 or PGA988 or rPGA988 . I don't know what difference letter "r" makes (which I would like to know by the way) but there is rPGA988A (Socket G1) and rPGA988B (Socket G2) which maybe similar in their appearance but are different in other aspects. Let's take a look at example of processor which lists only PGA988 in its description in Sockets Supported and rPGA in Package Size:
The problem here is that it is not indicated whether it works in rPGA988A or rPGA988B. How are we as consumers to take that? Does that mean it supports both sockets which would be not clear because this website states that sockets are different from each other and I citate:
Although the socket has the same number of pin holes as socket G2, they are not compatible with each other due to different position of one of the pin-holes.
Should we take that processors that only have rPGA988 mentioned are compatible with both rPGA988A and rPGA988B sockets? And if so, does that affect somehow on processor's capabilities, features, work etc.?
Here's information about my Core i3-330M I pulled from AIDA system information and benchmarking software:
If AIDA states: Package Type - rPGA988 and Platform ID - rPGA988A then why I don't see rPGA988A on http://ark.intel.com in processor's description? This is what given to me:
Finally, I saw several times socket named PPGA989 or PGA989 or rPGA989 (Socket G) being mentioned in some descriptions of motherboards and this Wikipedia webpage states the following:
(there are Socket G/rPGA 989 sockets that can take Socket G1/rPGA 988A or Socket G2/rPGA 988B packaged processors)
I did not find more detailed information about this mysterious socket but would like to know if processors that support either rPGA988A or rPGA988B will work as intended on socket rPGA989 or with some restrictions, limitations etc.?
Thanks to all who put in efforts in replying!
