Which operating systems will the core i7-8700k support

KingParm

Recently I bought a new rig(all the parts building my self)  but don't know which os my CPU will support because the kabylake cpus on new egg say windows 10 only and I'm not a fan of windows 10.

Older versions of Windows and Linux will work. However, there won't be any Windows updates on the older versions of Windows without any custom patches.

I was thinking about windows 8.1 because I have a licence for it and is it still supported?

"Support" is a very, very specific term that manufacturers use. The Coffee Lake and Kaby Lake chips are still x86 processors. Windows Vista+ will still run on these CPUs, it simply won't get "support" from Microsoft if you choose to - lets ignore that Microsoft doesn't even bother supporting Vista at all now, it's just me making a point.

 

The features that won't work if you use, say, Windows 7 on it, are things like Turbo Boost 3.0. You will *get limited security and feature updates* for your Coffee Lake CPU, so it's HIGHLY recommended that you bite the bullet and run Windows 10 if you have a Coffee Lake CPU, since you'll actually get all the updates you need.

 

Microsoft will not test or release newer updates for Windows 7, 8, and 8.1 on coffee lake CPUs - for no reason other than they want you to upgrade. But there's no physical incompatibility *stopping* them from doing it, it's just them trying to force you to upgrade and reducing their testing and support needs.

 

If you choose to run Windows 7, 8 or 8.1 on that build, it will work. You'll have issues (with Windows 7 especially) relating to power management, usb3, etc without driver updates - which intel may or may not bother to provide. You may putting your machine at risk of malware, since Microsoft may not bother to give you updates for all but the absolute worst security issues.

Well I guess there are some sacrifices that need to be made in life and I guess my os is going to have to be one! And thank you for the help

Short answer: Nope. It will nag the heck out of you telling you to upgrade without you using unofficial patches to force the machine to ignore your CPU generation. Who knows how long those will work for.

Of course any versions of windows will work, except they wont receive various updates or be supported by Microsoft (In terms of not being supported, this accounts for older operating systems such as windows XP, W98 and 95, etc). Custom patches might be applicable to these operating systems in terms of an update being provided.

Windows 8.1 is still supported and will definitely work with your system, and yes, your product key will also work with the OS as well.

Windows 8.1 is supported on hardware BEFORE Kaby Lake. We aren't talking about OS support in general, simply that Microsoft forces people using those CPU's to upgrade - or use third party patches - in order to get all updates.

Don't put artificial roadblocks on your hardware by sticking to Windows 8.1. 


Windows 10 is a fantastic OS, certainly better than 8.1. Just bite the bullet and upgrade.

It's the other way around. The 8700k doesn't support Windows, Windows supports 8700k.

Back to the question, any Windows operating (except IoT core) should run on your machine because they are using x86/64, which means all the instructions used by Windows will behave the same on any Intel chip built around the x86 instruction set.

However with every new Microsoft OS comes an end to the previous one, cutting support within a few years. Which means that things that may benefit you like hardware x265 encoding which is only present since Kaby Lake I believe, certain instruction set extensions like AVX, MMX, SSE won't be used by older operating systems. It doesn't mean you won't be able to use software that use these but generally a lot of programs depend on the OS having these instructions as functions in system DLLs.

 

Overall I think you are better off with the latest Windows OS since I am guessing you didn't buy an 8700k to play minecraft. Windows 8.1 might do as well but you will definitely miss out on a few features and note that mainstream support will end in less than two months.

Starting with the 7700, Intel and MS colluded and made it that without the unofficial patch, the video driver wouldn't work for the igpu. Windows 10 is pretty and all, but the forced updates that cripple components without warning or speedy resolution is a major hassle. I prefer Windows 8.1. that said, I have an 8700k and Mobo arriving next week that I'm going to try 8.1 on. 

I hope it works. Either way I have licenses for it ready to go so I shall see if I'm pretty much forced into 10.
