Regeneration

It happened with LGA775, and it was bound to happen again. Intel obviously doesn’t want you to use the same motherboard for more than 12 months. With LGA775, we had an interesting concept. Socket debuted in 2003, but for every new processor line-up, you had to buy the new motherboard that used the very same Socket. If you bought 925X-based chipset, you could not use Dual-Core Pentiums, if you bought a motherboard that runs DC Pentium, it would not run Core 2, (some) motherboards that ran Core 2 Duo didn’t support Core 2 Quad and so on.

Probably the most humorous motherboard of them all was Intel’s own Bad Axe motherboard. Intel shipped out different revisions of the same motherboard with Pentium 4 EE955, Pentium EE965, Core 2 Duo, Core 2 Quad - and every time, a new CPU would not work in older rev motherboard, even though power consumption was cut dramatically.

Enter LGA-1156. According to friends at Fudzilla, next 18 months will see the debut of LGA-1156 for Core i5, LGA-1156B supporting integrated graphics and LGA-1156C. If we take into account that the company previously planned to manufacture this socket as LGA-1160 and LGA-1158, we should really take a good look at mighty Chipzilla.

another loosy article by someone who's against intel

most of the time a bios revision was enough to be able to run the new cpu on the old MB

and by the way it is not better with amd, except nvidia based motherboards for amd cost even more than good intel based motherboards

its true though, ive been noticing this trend iwth intel lately, they really seem to want yo uto have to buy a new board every time they release a new cpu, atleast amd's am2/am2+ supported a whole slew of processors and im really hoping the trend will continue with am3

Well I somehow agree with blindartist -
earlier Intel released a new socket every 1 - 1,5 year,
then it slowed down a little with socket 775 (a good board design needed only newer bios revisions to support new cpus).
But again - as I see it - they come back to the old habits on releasing a new socket every year or two which is bad and will result in more people coming back to AMD (imho).
Since i7 was a new architecture compared to Core2/Quad - I can understand the need of new socket.
I also can (eventually) understand the need of new socket for i5 - since it supports dual channel compared to triple in i7 and it's because of the cost cuts...
But hell - I would never understand why to release three sockets for i5...
One is not sufficient ? They should rethink this...

1156, 1156B and 1156C are probably going to use the same physical socket. However B and C will in all likelyhood require different boards / BIOS for the GFX connector (Core i5 will have a dual core + GFX version). As far as I understand a 1156B chip can work in a 1156 or 1156C socket but some features (such as the IGP) will not be available.

Much like we have LGA775 + SD-RAM, LGA775+RDRAM, LGA775+DDR, LGA775+DDR2 and LGA775+DDR3 boards for different hardware requirements. However labeling the different types by socket(as opposed to socket and memory type) could make it simpler for average joe to understand.
