Intel Makes Another Bad Decision, No Coffee Lake 8th Generation CPU Support on 200-Series ‘LGA 1151’ Motherbards

Aug 2, 2017

While I am personally excited for the upcoming Intel Coffee Lake desktop processors, it’s sad to hear that these mainstream processors will not be compatible on any LGA 1151 socketed main board that has been released since the Skylake processors.

Intel Coffee Lake 8th Generation Core Family Will Not Be Supported on Current LGA 1151 Motherboards – New 300-Series Platform In The Works

Just when Coffee Lake started sounding great and a really good technical uplift from the previous mainstream offerings, an AIB partner dropped the bomb and revealed that the new lineup won’t be supported on any LGA 1151 socket motherboard that has been released to date.

This means that all 100-series and 200-series motherboards will not be able support 8th generation processors from Intel and that’s a bummer. Intel is bringing higher core counts with very high clock speeds to the mainstream market but users who want to purchase or upgrade would have to ditch their current 100-series and 200-series motherboards although the Coffee Lake chips will definitely be featured on LGA 1151 socket.

In previous leaks, we confirmed that their would be a new socket known as LGA 1151 V2 which is pretty much the same thing but has a slightly different electrical pin configuration. This means that current LGA 1151 socket boards are not able to support Coffee Lake chips and the same would be true for 6th and 7th generation CPU support on the upcoming 300-series platform which is built entirely for Coffee Lake processors.

Coffee Lake S will be launching alongside the brand new Z370 chipset which is known as CFL-PCH (Coffee Lake PCH). The platform will feature the LGA 1151 V2 socket so while it will have the same number of pins as the current LGA 1151 socket, it seems like Intel is moving to ditch support of the Coffee Lake CPUs on older LGA 1151 socketed motherboards such as Z270 series. It is stated that Intel will clearly be differentiating the socket with the use of “V2” moniker so consumers don’t end up buying the wrong board for their Coffee Lake desktop processor. via Wccftech

This can be seen as a bad decision by Intel as Coffee Lake is very similar to Kaby Lake and Skylake processors in terms of architecture and design. Both Kaby Lake and Skylake chips were supported on 100-series and 200-series motherboards but you will not be able to do the same when 300-series motherboards launch. The 8th generation CPUs will be going up against AMD’s Ryzen 5 chips with 6 cores and 12 threads. It will be interesting to see how both platforms perform and how well the Intel chips are priced compared to their predecessors. For those who are interested in learning the specifications of the new Core SKUs, you can check them out here.
