asus confirms coffeelake could have worked in z270

[henson0115]

apologies if this has already been mentioned, i couldn't find anything, however it looks like the only thing stopping a 8700k working in z270 and maybe z170 is simply a bios and me update despite claims on the power delivery system.

Am I right in saying that AMD have promised to maintain socket compatibility for the next few years at least? So Ryzen 3 (hypothetical example) will work with a motherboard released for Ryzen?

yea 2020 from memory.
edit: am4 socket guaranteed until 2020.

The issue is some of the higher B250 boards would probably have worked too. If anything the motherboard OEMs probably have tons of the older 100 and 200 series boards still in the retail channels and nobody will really want to jump onto them now,unless EOL pricing is done,which means someone needs to pick up the cost.

Plus we don't even have any of the lower end SKUs like Pentiums,etc on socket 1151 V3 too.

I means its even stupider,when existing 200 series customers could have upgraded to a Coffee Lake CPU even if they had a G4560 in their system. Even one of my mates who has a Core i7 6700 would have probably upgraded their CPU if Coffee Lake worked in his motherboard,but he just gave up on the idea once he heard he needed to ditch it. I suspect he is not alone in that thought.

But now they have done this,together with the low volume of certain SKUs,means essentially the large volume desktop sales will be from early next year,and within the same time period or a bit later AMD apparently will be refreshing Ryzen too. They could have easily pre-empted all of this by not artificially blocking older motherboards from taking Coffee Lake and also alienating their older customers too.

this was my thinking, if it would have worked i would have gone from 6700k to 8700k, but im ditching that idea now a new board is required.

Andrew: Many of them are used for power control. It's possible that these are in preparation for the high-core count processors.

This interests me, maybe the 8cores can come to the z370 afterall.

imo you wont see an 8core z370, not unless they are pushed to bring one out. the only reason we now have a 6 core is because they really didnt have a choice.

 

[henson0115]

We shall see, although a 5ghz 6c 12t isn't going be made redundant anytime soon.

indeed, why bother with 8 when the 6 is more than capable and people are buying it. i think now amd are back in the game we may see less stagnation though.

there is no extra power delivery if you read the article

Watching Linus talk about it here:

https://youtu.be/0qRpRITk6k4?t=51m52s

Has made me think that the likelihood of Z370 supporting 9th gen seems more likely now. As he says, if they were truly just screwing everyone over, why would they both altering the pins/power delivery at all? Surely they could just push a BIOS change and nothing else. Also, Intel has supported 2+ generations of CPUs on the same motherboards for the past 10 years. This extra power delivery could mean the speculated 10nm 8-core 9th gen CPUs might work on Z370.

for the third time in this thread, there is no extra power delivery... according to asus.

If you read what Andrew Wu says, he doesn't outright say it has no difference. It could affect system stability, or might indeed have issues on budget boards. We need more sources to find out the full extent of the truth that a power delivery change was necessary

and yet they outright say it could work with a bios update; does that sound like it wouldn't work unless there was extra power delivery on the board?. how much extra power would 2 more cores require? 8700k is 95w, 6700k is 91w, i call bs on the extra power delivery, considering i know full well my cpu draws more than 91w oc'd to 4.6ghz.

Look at the naming though - its the same 300 series naming. In all those cases,Intel NEVER stuck with the same series naming for improved chipsets in recent history - Z60 to Z70 series,Z100 to Z200 series.

Each of those chipsets launched with a new CPU line. Using what you said,it the chipset should be named the Z470 and being launching with 10NM CPUs.Intel has NOT released a new HIGHER end chipset without a whole series name change for yonks.

This is apparently being launched for the same line as Coffee Lake. So two new high end 300 chipsets for the same line - that is not usual at all.Don't forget what ASUS said - the Z270 can work with Coffeelake. That means power delivery for the Z270 is fine. Why wouldn't it be fine with the fact a number have massively over-rated VRMs?

So that indicates to me if there is changes to power delivery in the new socket,its obviously NOT for Coffeelake,its for Cannonlake,and that increases the chance that the Z390 is the chipset that has that change.When you look at this logically,it makes sense. Coffee Lake is basically just Skylake/Kabylake with two more cores,released a few months before it was expected,so they adapted the current Z270 to the new socket,since it was quick to do.

Plus,another thing since the Z390 is technically the same series as all the other chipsets,Intel has not broken the two CPU cycle. It has happened before - it happened with the P4 and Core2 also,where the power delivery changed with chipsets which technically could run a Core2 CPU but were designed for the P4. AMD did the same with certain sockets too and so on. It could not be even a case of power delivery in terms of current itself,but the way it is delivered.

For all we could know,the Z390 might be literally the Z370 but with differences to the power delivery and regulation more suited for Cannonlake.

I mean did you even know the P67 chipset could work with P55 CPUs?? ASRock made a motherboard which worked with older CPUs. But the main change to P67 was things like power delivery,etc.

OTH,you might be right,its simply for moar money making opportunities.

But look at this post by Eurocom who are responsible for high laptop reference designs:

http://www.tomshardware.co.uk/intel-z390-chipset-coffee-lake,news-56789.html

A lot of those base reference designs are used by companies like MSI,etc for their gaming ranges.

Having said that only one company can clear this up - Intel. If they did that it would clear up any ambiguity.

TBH,none of us really know where this will go as we are simply speculating it will or will not be supported.

spot on.

Some of those high end Z270 boards are really expensive, it appears what was said in the bit-tech interview all that is needed is a bios update to accomodate the new cpu's.

some of which offer nothing new that we didn't have on z170 or z270. im not even going to mention intel dropping tick/tock.

It's a bit comical to think that people wanted to use the previous motherboard line up with the latest CPU in order to save money. If you really wanted to save money, you could've used the previous CPU along with the previous motherboard.

its a big comical to think that some people wouldn't if they could. its not a previous line up either, its all part of the new process - process, architecture, refinement, 3 year support cycle for a chipset.
