Choosing a motherboard for a CPU like the i7 9700k is no easy task. With all the vast options available out there it becomes harder than ever to decide what will be best for you. And when it comes to a popular gaming CPU like the i7 9700k you really want to tap into its full potential.
If you get a sub-par motherboard for i7 9700k then you’ll just bottleneck its performance. There is also a budget that needs to be kept in mind. I made this guide to help you choose the best motherboard for i7 9700k that covers most budget and performance requirements.
The 9700k processor comes with eight cores and eight threads when compared to its predecessor. It had six cores and 12 threads. Also, Intel decided to take the hyperthreading off of it. Yes, I know very confusing, but that’s what Intel did. Now, these are both unlocked and overclockable.
How to choose the Best Motherboard for i7 9700k?
Frankly, a Z series board is the only thing you should consider for i7 9700k even if you don’t plan to overclock.
If you’re spending this kind of money on your CPU, you could easily buy a Z-series board for your i7 9700k. You would want the extra features, such as The HSI Lanes, the PCI Express Lanes, and the overall quality of features for this price point. Even if you run them at stock, one benefit to a Z-series board is it allows you to use overclocked RAM.
Both of these chips only support DDR4-2666 at normal speeds. If you get the H board the B board, namely the first H310 or the H370, you cannot run your RAM faster than DDR4-2666. If you want to run DDR4-3200 or 3600, you must have a Z Series board. It’s the only way to do it. Even if you don’t overclock your CPU and want to put a faster RAM in your system, then you have to get a Z-Series board.
Comparison – Z370 vs. Z390
The Z-Series boards start at 110 dollars, typically the Z370. Now that’s not too much more than the H boards, but please don’t buy the Z370 boards in the lower price range like the Gigabyte Z370. They just give up everything to get that price point. A 150 dollars should be your minimum buy-in point to a Z-series board (Z390 motherboard) where you get decent quality components. The differences between the Z370 and Z390 are night and day. For the lower price range in Z370, you give up the Intel LAN Chip, decent onboard sound, any resemblance of RGB, USB ports, and in most of the lower end Z series boards you get only a single M.2 slot.
The Z370 is for the most part very limiting for i7 9700k, and if you’re confused, you have spent or going to spend $350+ on your CPU, then spend $150 on your motherboard and get something decent. If you’re interested in Z370 motherboards the check out my guide to choosing the best motherboard for i7 8700k where I have specifically covered Z370 chipset boards.
Now having said that unless you already own a Z370 buy a Z390. The prices are not substantially different, at least when I’m writing this review. The Z390 has some excellent new features and frankly just gets the newer boards. However, if you already have a Z370 or you find a crazy good deal on a Z370, don’t be afraid to get the Z370 and put your i7 9700k CPU on it. If you find an awesome deal, by all means, grab it.
Just be aware that if the motherboard has not had its BIOS updated, these Z370s will not run the i7 9700k or the i9 9900k until they’ve had a BIOS update. For most of them except for the Super Premium boards that have BIOS flashback, you must have a working CPU that they support, to update the BIOS.
Just keep that in mind if you buy a Z370 to put a ninth-generation chip. Actually, in all fairness, that’s true for most of them. If you buy the first-generation H370 or B360 board that was manufactured before the ninth generation comes, some of those aren’t going to work without a BIOS update. So make sure you buy a recently manufactured board or preferably buy a Z390 for the 9700k processor.
