like the title above, will intel decide to discontinue 775? or continuing it with better fabrication processor? i decided to stay on 775. no other reason, 1366s run hot and i have to spent extra money on cooling...not to mention that platform is extremely expansive and power bill will be infinitely high... then the 1156 was simply a bad design because of the socket itself and also compsuming more power than current core 2 line on 775 and also some hardware capability issue. after seeing these platform i think 775 may be the most stable platform intel ever made(never crash, good with I/O support and hardware capability).

just wish core i3 or 32nm processor will be on lga 775.

775 is dead. 1156 is the mainstream socket that Intel will use for a while. I don't know why you think 1156 is a bad design - it is perfectly fine, and has only had a few minor issues with extreme overclocking.

damn...why are they change everything suddenly....i remember they were still provide 478 pentium 4 northwood/prescott and celeron d until last june(2008)......and now lga 775 is dead. as for a socket lga 775 wasn't that long compare to old school 478.....(lga 775 is being around only for 5 years come on! 478 been last from 2001 to 2008....7years!) and in theory lga 775 still able to provide bandwidth even for processor like core i7 965. that socket still haven't reach its limit and they are shuting it down because of market stratage? i wonder their head were hit by rocks.....

Thats incorrect. Socket 478 lasted from 2001 to 2004. LGA 775 came out in 2004 as well.

The only 478 that went from 2004 to 2008 was PGA 478 for the laptops, not for desktops.

LGA 775 outlasted 478 by almost 2x.

They had to change sockets because of the IMC just like AMD did when they went from no IMC to IMC. Then again when they went from DDR to DDR2 and now AM3 is for DDR3. The IMC is very beneficial only problem is that now the mobo might have to change sockets with new memory types instead of a chipset switch. That means if you want DDR4, you will need a mobo with it and a CPU that supports it instead of just a chipset on a mobo. Instead of a mobo upgrade only, you have to upgrade the mobo, memory and CPU.

Socket 775 cannot support an i7. This is because the interconnect between the processor and the board is fundamentally different between the i7 and the core 2 series CPUs.

The i7 has an IMC and QPI, the Core 2 Quad has a FSB, and the 1156 i7/i5 has a DMI/IMC connection, as well as several PCI-E lanes. These make the sockets fundamentally incompatible, and it isn't just marketing that causes Intel to change sockets.

so i see...the whole reason is not because 775 cannot satisfy newer processor but because the new design of intergrated memory control (IMC)that which 775 was lack of. so it means it was the architecture that was limited 775.......

but another question....will there any new processor that support 775

well they were still around....p42.6ghz/p4 2.8ghz(northwood), p4 630(prescott) and biostar p4m800/p4m900-m4, msi 945GCM478-L were on the stock until early this year even after intel announced discontinued of p4 netburst. some mb menufacturer also provide 478 with pcie 16x and ddr2.

strangely newegg still has these platform

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

that biostar p4m900-m4 came up octorber 2008, 2 months after the discontinuation. msi also still designing chipset for 478 too

so if 478 hasnt dead yet than there would be no reason for 775 to be disappeared

I said. 775 can feed same amount of bandwidth on core i7 as on 1366 if not IMC issue and architecture limitation. 1156 is just a crap

Socket 775 will do the same. The mobos and CPUs will last until Intels stock is depleated and the sellers inventory is gone.

As for the mobos, its up to the mobo maker to decied if its worth continuing them. I think LGA775 will be around until at least 2011. Hell Intel released som new versions of the LGA775 45nm Yorkfield quads, noted by a "S" at the end in Q1 and Q2 of this year. There is the Q9400s, Q9505s and Q9550s. They all ahve the same as their original versions just a 65w TDP instead of 95w.

No, 775 is dead. No new 775 CPUs, only the remaining stock.

yeah i believe so since non of any processor can "theorically" use all 775's bandwidth in today. 1366 is just another 775 but that support upper level achitecute like hyperthreading, imc, intergrade gpu on die....but again...who need these!? 775 simply offering more IPC/ less heat/ power comsumption than 1366, not to mention "creeple" 1156 that had nerrow bandwidth and higher heat/power comsumption. seems like non of these platform will replace 775 completely in near future.

PS: that 1366 reminding me of slot 1 pentium II back to the day. it did not provide more bandwidth than socket 7 but consuming more power and less IPC....hopefully history wont happan again....

What makes you say that 1366 and 1156 have lower IPC? It's exactly the other way - current 1156 and 1366 CPUs have higher IPC than any 775 CPU out there. Power consumption is CPU dependent as well (and in many cases, 1366 and 1156 can actually beat 775 in idle power consumption) as well.

As for 775's "Bandwidth", it actually was being used at basically 100%. The only connection a 775 CPU has with the motherboard is the FSB, and it was becoming a limiting factor in several more memory-intensive uses, even at 1600MHz (though not as much in home use). That is why the QPI and IMC were added, which absolutely required a socket change.

If you want an example of a truly short lived socket, try Intel's Socket421.

Would it be 423 http://en.wikipedia.org/wiki/Socket_423 ?
Can't find anything on 421

The wonderful early Pentium4's with that horrible Willamette core...

AMD's short lived socket was the Socket 754... but at least the Athlon64's were some pretty solid single core performers.

God I loved my AthlonXP 2400 :D
