p55 vs p67 & x58 vs p67....exactly how can they be compared?

[nix253]

ok guys i'm not knowing too much technological details of all there 3 chipsets but still i can understand what really differentiates one chipset from another..... still when i saw sandybridge's reviews i couldn't exactly figure out one review's quote which said something like although p67 right now only features same pci-e lanes distribution in motherboards as p55 has in it's, we can expect to see two lanes running at full speed in future products.....

does that mean p67 has a lot better pci-e and memory control than the p55 n x58?...what does it have n not have that these other 2 chipsets don't n do respectively?....i mean how much backwards have p55 n x58 users have gone now that this p67 has been released....specifically p55 users(including me)....

For the time being, the x58 still offers features the p55 & p67 don't offer. Tripple channel RAM for one, and true 16x PCI-E graphics for SLI & CF.

Keep in mind that the x58 requires the LGA 1366 & the P67 is designed for the new LGA 1155.

This is a direct comparison of the chipsets themselves. Features aside there really isn't that much different between P55 and P67; however, there is a fundamental difference between how X58 functions and P55/P67. Best described in pictures, although if you have any other questions feel free to ask and I'll try to explain it a little better. First picture is a X58 block diagram, second is a P55, and third is H55/P67:

so ok i guess both p55 and p67/h67 support upto 16 lanes only for pci-e 2.0 ....isn't it?....but there's no multi-gpu setup shown in the h67 diagram..... does that mean that someone should go for p67 only in lga 115 socket if he wants to do a multi-gpu setup?

and wats the difference between intel's matrix storage and rapid storage technology?

also as far as i can contemplate these above diagrams the major differnce between p55 and p67/h67 is just the storage capabilty?.....

but DMI link shown in both p55 and x58 is just 2GB/s between proccessor and chipset while in p67/h67 it is 20 GB/s ....so that's a large differnce isn't it?....does it favour 1155 socket for better performance?
