Current Intel Chipsets explained...

AFAIK there isnt one article, youd have to go through an article for each new chipset release, but in an attempt to sum up for you, here goes
OK

X58 is socket 1366, this take Intels core i7 9 series chips
P55 is socket 1156, this was originally designed for the i7 8 series chips and i5 7 series
H55/H57(57 not 75, typo I presume) is socket 1155, and was designed for i5 6 series and i3

H55/H57 are pretty much the same, the H57 merely has a couple of extra PCI-E lanes

also 1156/1155 are quite interoperable, you can put the chips from one into the boards of the other and vice versa

The actual differences are that the 1155 socket chips basically have built in gfx, the 1156 doesnt
And the 1156 has less bandwidth available then the 1366 so for multiple gfx card set ups the 1366 is better

Also to note is the 1155/1156 uses dual channel RAM where as the 1366 uses triple channel RAM

Does that clarify whatever you were after?
 
P55 motherboards that use the NF200 chip don't have any bandwidth issues when used for SLI - AFAIK this does not help for crossfire or when using the cards individually.
 
Whats the current H55 board of choice as i see a lot have new revisions with USB 3 ?

A few weeks ago everybody said Asus P7H55-M and the Gigabyte GA-H55M-UD2H.

Is'nt H55/57 just the socket 1156 version with onboard graphics just as G31/41 is for socket 775?

Socket 1155 will be 1156's replacement when Sandybridge is released later in the year.
 
More in depth explanation on anandtech, theres a few subtle differences but basically yeah (was trying to keep simple n summarise), its complex cos the the different chipsets P55/H55/H57 use 2 sockets 1155/1156 but are interoperable with the various chip technoligies, eg Clarkdale, Lynnfield. Dont forget the gfx is on the chip rather than the board, but you still need the right board to "decode" the gfx coming from the chip (again simplifying)

These are the 3 chipsets in diagram format

Well personally I believe Anandtch, techreport and all the other reputable hardware sites over wikipedia, espcially seen as how its factually wrong by line two

Wikipedia

Processors of LGA 1155 and LGA 1156 socket is not compatible with each other since they have different socket notches

A Nice sum up of the interoperability from Techreport

You may have heard that Clarkdale brings with it a new socket type, dubbed LGA1155. That's true, but it's not entirely new: this is just one fewer pin than the LGA1156 sockets used with Lynnfield Core i5 and i7 processors, with the extra pin used to signal integrated graphics capabilities. The reality is that LGA1155 and LGA1156 processors and motherboards are largely interoperable: one may, for instance, install a Core i5-750 in an H57 motherboard and use it, so long as a discrete graphics card is available. Similarly, we installed our Core i5-661 in a P55 board with discrete graphics, and it worked effortlessly. Just don't expect that H57 motherboard's VGA port to do anything when you have a Lynnfield processor installed, and don't expect to make use of a Clarkdale IGP on a P55 board.

P55/H55/H57 are all LGA1156, so yes an Intel Core i5-661 (LGA1156) will be interoperable between then...

LGA1155 will be used with P67/H67/Q65/Q67/B65... and will not be able to be used with LGA1156 processors, see Here

They are wrong I believe, what are they reffering to when they say socket 1155? 1155 are the new Sandy Bridge mainstream parts coming out in Jan next year and will not work on current 5 series chipset boards.

Or when they say 1155 do they mean socket 1156 chips that do not have VGA? which will work in H55 boards but will not be able to use the onboard VGA as there is none in the CPU?
 
OK I stand corrected, damn techreport, they shouldnt be making mistakes like that, makes me look daft(er) lol
Thanks for the Intel link jbloggs, was sceptical re wikipedia link seen as how any man or their dog can go on and type whatever they want in, I never trust anything from there as a single source
