Why Coffee Lake cannot work on Z270

They are both LGA 1151, so why not?

Why Coffee Lake cannot work on Z270

 

For a long time it has been known that Intel's upcoming 8th generation Coffee Lake series of CPUs would be arriving on LGA 1151 motherboards, leaving many to wonder if Coffee Lake would be backwards compatible with Intel's existing 100-series and 200-series motherboards. 

Over time it has been confirmed that Coffee Lake will not work on 100-series and 200-series motherboards, though Intel has never officially gone on the record to give a reason why, leading many to assume that "Intel is blocking backwards compatibility" or have even gone as far as to say that motherboard makers have forced Intel to do this to achieve greater Z370 motherboard sales.

Intel has now released their "8th Gen (S-platform) Intel Processor Family Datasheet", which reveals a lot about the company's new Coffee Lake series of CPUs. The data included in the 155 page long PDF has also revealed exactly why Intel's existing LGA 1151 motherboards cannot support Coffee Lake.

they are reserved pins aren't they, meaning they do nothing on z270 boards, that might mean that the cpu would have less max power delivery, but it wouldn't make it not work, and at least kaby lake cpus should work on the new z370 boards with just some bios compatibilityQuote

I presume that you are not an engineer? Because it's not that black and white Quote

well i am an engineer if that helps.

but a mechanical engineer.

i firmly believe that 20% is technical reasons and 80% is financial reason behind the decision to create an uncompatible CPU from kaby lake (aka coffee lake).

i also firmly believe that with a bit effort 8 core cpus could run on Z270 chipsets.


intel is one of the dirtiest tech companies you can run into. they proved that over and over.
of course they will make some changes so it looks like it was necessary. i would do the same.

but nobody can tell us if they could not have made the changes to the CPU instead of the socket.
coffee lake is not draining more watt then kaby lake.

and coffee lake was not build in one year.
what about building chipsets and sockets that are a bit more futureproof?

planned obsolescence, that´s what this is called.

intel does not even try to be futureproof!
because doing it the way they do.. it even EARNS them MORE money.

According to Intel, LGA1151 socket on Z370 motherboards had to be modified for better power delivery for 8th Gen Core CPUs. The backward and forward compatibility questions could’ve all been avoided if Intel added at least one more physical pin or simply name the new socket as LGA1151v2. That did not happen. The electrical pin layout confirms that Coffelake has some RSVD (reserved) LGA1151 pins now occupied by VSS and VCC pins.

Every company is dirty, the world is dirty, most individuals are dirty. The way of the world. Like I said in the other thread, the end result would've been the same (new boards), it's the way it is, one can either accept or reject that.Quote

But I still don't think it is Intel that is the main bad guy. The MB manufacturers win more on this.

And the hole TIM thing is a win for the cooler manufacturers. Yes I am wearing my tinfoil hat Quote
