Rumour control: P45 will be last LGA775 chipset
Leading motherboard manufacturer says that P45 will be the most important chipset for motherboard manufacturers for a long time
Crossing the bridge between NetBurst’s swansong chips and several generations of Core 2, the LGA775 socket has had a good innings. However,t the word is that Intel’s forthcoming P45 chipset will be the last chipset to support the socket.
This won’t be a huge surprise to those of you who’ve seen the leaked pictures of Intel’s forthcoming Nehalem CPUs, but an anonymous source at a leading motherboard manufacturer told Custom PC that Intel’s shift to a new socket is likely to make P45 a very popular chipset.
‘The P45 Chipset is so important for motherboard manufacturers,’ they said, as ‘it’s probably the last LGA775 Intel chipset.’ According to our source, this means that the chipset will have a very long lifespan, with a huge share of the chipset market. Our source also said that, as a result, the company was putting more effort into the design, BIOS and components of its new P45 board than with any previous boards for a long time.
Although it was originally ridiculed for swapping CPU pins for pads, Intel’s LGA775 socket has had a remarkable lifespan of several years, especially when you consider that AMD has gone from Socket 939, through AM2 and now AM2+ in a similar timeframe.

Aren't AM2 and AM2+ are compatible with each other (albeit with restriction of extra features in AM2+ CPU's for AM2+ boards), if AMD are to be believed the same will be for AM3 as well. Although socket 939's demise came far too soon...that I agree with. My poor 939 board redundant after 3 years...all for one diddly pin and DDR2 support which was not as much of a needed feature since the on board DDR1 controller outperformed Intel's original Northbridge/FSB/DDR2 design for the most part.

P45, lol, quite an appropriate name for an end of line product heheheh ;)

I dont know why they bothered to be honest, they are esentially limiting themselves to the enthusiasts new build market. I cant see anyone with P35 or later chipsets upgrading when Nehalem is on the horizon. Is it going to offer any performance over P35/x38/48, maybe but will it be worth the hastle of rebuilding your PC? doubtfull. Of course people building from scratch will consider it, but as with everything it will be expensive initially, and people wont pay premiums for somthing thats basicly obscelete before it even hits the shops. Seems pointless to me, but im sure theres some silly marketing/business reason for it.

P45 = Redundant Seriously, with all the Ragimised Maximi and P5E's showing that x48 = high binned x38 (mine included) out there can we really expect P45 to offer sufficiently more (SLi please Skulltrail shows it can be done, MB vendors take note!) than P35 (or P965 or P975) to be worth upgrading to before Nehalem and its (TEC friendly) bigger footprint and demand for DDR3 arrive?

using words you picked up as it obviously came out stronger than I intended it to. I get frustrated when people don't do their job properly, especially if their are lazy to do simple things that have a big impact on the end result. So I stand behind my criticism of the article, however I will try to improve how I express my opinions. Peace...

Constructive criticism doesn't amount to be being a complete ass, and looking like one in the process. Here is a link; http://dictionary.reference.com/browse/constructive%20criticism If you could outline how you were helpful and not just spouting vitriol with such lines as "Awsome journalism, well done. Keep it up guys." i'd be most interested..

Is a jealous AMD user ;) After taking triple tactical nukes has exploded in rage as Intel comes up the the triathalon of weaponary: The Death Star :)

Its quite a big difference actually, as Nehalem will have an integrated memory controller, ddr3 compulsory and a lot more pins. You cannot adapt more than 775 pins into an LGA 775 socket without a massive performance loss. There would be compatibility problems, and the cpu would probably touch the vrms. The last socket that worked on was socket 370 and slot 1 (if memory serves), where slot 1 was basically socket 370 cpus soldered onto a motherboard daughterboard. Also, there is HT (or similar tech) on socket lga1366. plus, intel want to sell their new chips.

Although Nehalem is bigger it has the same shape as current 775 cpus, so why cant motherboard makers make an adaptor which allows 775 cpus to sit in the center of the new socket so it can be used in the Nehalem motherboard ? This would allow the rest of the world who have 775 motherboards to use their CPUs in the new socket and in time swap that cpu for a Nehalem which would use all of the socket. How hard could it be do make an adaptor and make it work ?

CPC to explain everything everywhere. Why is there a link for Nehalem article? I know more about Nehalem than I know about P45. Would it be so difficult to do the same link to old P45 article? Are you honestly saying that readers know more about P45 than Nehalem? No! Cost of posting link for Ben would be less then benefit for readers that would not have to look it up. Do you get my point?

If you are a high-performance computing enthusiast, you would be well aware of the imminent introduction of P45 chipsets; and if you don't know about P45, well you should have the motivation to look it up. If CustomPC had to explain every component in a summary in every article they wrote (say talking about Penryn - and the LGA 775 socket has 775 pins) - i mean they'd never get the news they are trying to tell across. CustomPC writes concisely and I'd strongly object if they had to follow the style you are suggesting, marekkolesar. So constructive criticism; make the effort to look it up yourself if you don't know about it.

Thats a whole lot of new pins they've got there. I'm guessing you don't need 600 pins for a memory controller. Thats means that the FSB component of Quick path is going to be quick. *starts saving pennies for Nehalem*

LGA775 has got it's P45 then?... Just squeezing the last drops out of that old joke.
Comment by mr_nips at 3:48pm 2nd May 2008
4 months ago, well done. It didn't change the fact that I had to look for info elsewhere, did it? It would not hurt to add another line and mention that 1600FSB is the feature. Just because you guys know it does not mean that everybody else does. Take is as constructive feedback from my side.
Comment by marekkolesar at 1:44pm 2nd May 2008
We've already reported on P45 as far back as January this year - there aren't many new features it has apart from 1,600MHz FSB support. The point of this story was to point out that, because P45 is the last LGA775 chipset, it's going to be a very important chipset for motherboard makers to get right, so we could well see some decent boards based on it.
Comment by hardwidge at 1:05pm 2nd May 2008
article is this? You say P45 is coming but you won't say what futures it will have. Is the point to tell me that P45 exist so I can go and Google info about it? Awsome journalism, well done. Keep it up guys.

i thought this was common knowledge, it wont happen until late 2008/2009 anyway.
