Coffee Lake (14nm++) is launching in Q4 2017, https://www.anandtech.com/show/11843/prices-of-intels-coffee...

Can a Coffee Lake CPU work on a Kaby Lake / Skylake motherboard?



sort by: page size:

That claim is for Coffee Lake. Intel have recently taken the opportunity to make their line even more confusing; _these_ 8th generation CPUs are "Kaby Lake Refresh". Coffee Lake will be along later.

I assume the New CPUs are 14nm Coffee Lake-H:

I'm actually surprised they could narrow it down even that much. The skylake and coffeelake iGPUs always seemed basically identical to the kabylake one.

It's not always. For example "8th gen" Intel has both Kaby Lake and Coffee Lake CPUs, some gens have a mix of 14nm CPUs for desktop and 10nm for Mobile. It's honestly pretty confusing as to which Lake follows what at this point as they are slight refinements of slight refinements.

AMD is at least making it so the second digit will indicate architecture (the first will be year released).


I think they confused Coffeelake with the new Skylakes

But skylake, not kaby lake...

The uarch and core differences between Skylake, Kaby Lake, Coffee Lake and Comet Lake are neglible. The most significant changes were claims of hardware fixes for some Spectre and Meltdown variants in Coffee Lake, which is still a really minor change. The minor IPC differences arise from different cache sizes and interconnect.

That’s not the only thing, but yeah I suppose you can get Skylake/Kabylake now with the HAP workaround.

Z170 boards supported Skylake and Kaby Lake(with firmware updates).

Disappointing that those boards won't see the new more cored processors.

There's some... interesting power consumption with the latest i9 OC'ed. https://www.eteknix.com/intel-core-i9-7980xe-extreme-edition...


Doesn't look like Kaby Lake supports LPDDR4: http://ark.intel.com/products/97462/

If you really want to be confused, try to figure out which laptops have Coffee/Ice/Tiger Lake and whether it's 10nm or 14nm.

Take a look at 10th gen Intel mobile processors: https://en.wikipedia.org/wiki/List_of_Intel_processors#Lates... (You'll have to scroll a page or two)

11th gen seems to be a mix of Tiger Lake and the upcoming Rocket Lake iterations.


These are effectively i3/i5s there is no Kaby Lak SP/X (well there is technicall X but these are 2-4 core CPUs which isn’t a traditional X class) and it’s not coming the 2018 refresh is Cascade Lake which is annoying since you’ll have Coffe, Canon and Cascade Lake all the the same time so I’m guessing it will be CFL, CNL and CSL not confusing at all.

> which Many Lake has accelerated decode for

Only Kaby Lake has VP8/9 hardware acceleration. Skylake doesn't.


It seems that this eliminates support prior to Kaby Lake. Is there any big difference between Skylake and Kaby Lake? Windows 11 does similar cut.
