NZXT, a company much better known for products like cases, power supplies, and coolers, is dipping its toes in the motherboard waters with an Intel Z30 based motherboard named N7. The N7 is nearly completely covered with shrouds exposing only the pertinent parts, making for a unique looking motherboard. We'll put it through its paces and see where it stands after our testing.

The NZXT N7 Motherboard Review

A couple of weeks back an email was forwarded to me with the subject line reading along the lines of 'NZXT Review, It's not a case!' I think we all appreciated that humor as clearly, that is one of several product lines we are familiar with NZXT for. When I read it was a motherboard I think we were all surprised to hear about the entry into this market. But nevertheless, they came forward with the Intel Z370 based N7. 

Default performance on this board was tough to compare as we only have datasets with varied Uncore frequencies. However, that seems to be a function of the motherboard and will vary throughout the Z370 testing. It is tough to compare it directly to the i9-7900X because of its difference in core/thread count as well cost. We can almost purchase three i7 8700Ks for one 7900X. When compared with its peers though, it was leading the small pack even with a slight Uncore deficit. As we saw in testing, only a couple of results really showed a significant difference, but certainly worth noting in comparison. Boot times were a bit slower, but that was also due to some curious issues with the monitor and when it turns on with this motherboard. Occasionally the monitor wouldn't detect a signal as the system booted, but when I switched to a different monitor (same cable), there wasn't an issue. It is difficult to pinpoint where the issue is, however, this is the first time I have seen this behavior. 

As far as storage options go, the way the N7 is configured, with a total of four SATA ports, allows for the two M.2 slots to remain at PCIe 3.0 x4 bandwidth regardless if all are used. The chipset can support six, but instead of having all six on there and sharing, they went without. I have to expect for the vast majority of users this will not be a concern. Those who require more than four SATA ports will have to do so via expansion cards. 

The N7 has a total of five PCIe slots with positions 2 and 4 (the full-length slots), connected to the CPU and intended for video cards. Slots 1(x1), 3(x4), and 5(x4) are all connected through the chipset. Back panel connectivity consists of four USB 3.0 ports and five USB 2.0 ports, CMOS Reset button, HDMI/DisplayPort Video outputs, the Intel RJ-45 port and the 6-plug 7.1 channel audio stack. The board does not have any USB 3.1 (10 Gbps) ports. 

The NZXT has placed an MSRP of $299.99. That price point puts in in direct competition with some solid motherboards. The ASRock Z370 Professional Gaming i7 is priced at $300, the ROG Maximus X Hero (Wi-Fi AC) sits at $280 with the Gigabyte Z370 AORUS Gaming 7 prices at $250. At the same or lesser price point, the ASRock and ASUS include Wi-Fi and USB 3.1 (10 Gbps). Pretty stiff competition around the $300 mark.

EDITOR'S NOTE: On 1/19/18, NZXT released a statement acknowledging what many reviews said that the price was too high. The MSRP has been lowered to $249.99 in response. With this came some changes to what is included with the board. In order to offer the lower price, they have removed the bundled RGB LED strips and extensions. Additionally, NZXT has doubled down on their confidence of the N7 and have increased the warranty period from 3 to 4 years. 

Information on Intel's Coffe-Lake CPU Desktop Processors

One important piece of information to note: technically these processors use the LGA1151 socket, also used by 6th and 7th Generation processors using the Z170 and Z270 chipsets. But due to several (albeit minor) difference in the pin-layout of these two sets of processors, the 8th Generation Coffee Lake will only work in Z370 boards and are not cross compatible. Back in October 2017, Ian Cutress reviewed a couple of processors (i7-8700K and i7-8400) in the Coffe Lake lineup - details on the rest of the product stack are listed below.

At the top of the stack are two Core i7 Coffee Lake processors. In previous generations ‘Core i7’ meant that we were discussing quad-core parts with hyperthreading, but for this generation, it moves up to a six-core part with hyperthreading. The Core i7-8700K starts at a 3.7 GHz base frequency and is designed to turbo to 4.7 GHz in single-threaded workloads, with a thermal design power (TDP) of 95W. The K designation means this processor is unlocked and can be overclocked by adjusting the frequency multiplier, subject to appropriate cooling, applied voltage, and the quality of the chip (Intel only guarantees 4.7 GHz).  The Core i7-8700 is the non-K variant, with lower clocks (3.2 GHz base, 4.6 GHz turbo) and a lower TDP (65W).  Both of these processors use 256 KB of L2 cache per core and 2 MB of L3 cache per core.

When compared to the previous generation, the Core i7-8700K starts at a higher price, but for that price comes more cores and a higher turbo frequency. The Core i7-8700K is a good example of how adding cores works: in order to keep the same power consumption, the overall base frequency has to be lowered to match the presence of extra cores. However, in order to keep the responsiveness higher than the previous generation, the single thread performance is often pushed to a higher multiplier. In almost all situations this counts as a win-win, and makes pushing for the 6-core part, on paper at least, a no-brainer.

    I appreciate I don't read as much as I used to, but I've been reading Anandtech for 20 years and this is the most confusing first page of an article I've ever read.

    "Default performance on this board was tough to compare as we only have datasets with varied Uncore frequencies. However, that seems to be a function of the motherboard and will vary throughout the Z370 testing. It is tough to compare it directly to the i9-7900X because of its difference in core/thread count as well cost. We can almost purchase three i7 8700Ks for one 7900X."

    1. What is Uncore?
    2. Regarding this sentence in particular: "to compare it directly to the i9-7900X" I don't understand; you are trying to compare this motherboard to a CPU?
    3. "We can almost purchase three i7 8700Ks for one 7900X." ... Ok? What is the significance of that to this review?

    I apologise if I sound harsh, but I was fascinated to read about this unusual motherboard. Anandtech has been my "go to" site for years and I was excited to see this article, but I'm left feeling confused before I've even finished reading the first page.

    Thanks for the input.

    1. Uncore is Non core parts of the CPU like Cache/Memory Controller, etc.
    2. Its intent is to was to setup the fact that the only datasets I had available were the 7900X ones (otherwise it would have been two others with different uncores which I threw in there to at least have an apples to apples type of comparison.
    3. When comparing performance, many people attach $ to it.

    That paragraph could be improved indeed.

    Shouldn't that be "transcore" and "ciscore"?

    lol

    Ayyyyyyyy, gender memes in tech articles. Good one! I enjoy your witty sense of humor! You should feel good about yourself today for making that stretch. Reply

    Terms from gender ideology, which is all about extreme self-deception and lack of self-esteem, really don't lend themselves well as descriptors in any area of science and technology, whether with or without humerous intent. Reply

    Honestly, I just don't get it. But trans and cis are technical/science terms. They are used in chemistry all the time and to denounce psychology like that is rather ignorant. Reply
  • we - Tuesday, January 9, 2018 - link

    @Death666Angel, Aha, was their scientific usage the implied reference? Anyhow, under the umbrella of psychology you'll find some proper science, but also a lot of nonsense. Sigmund Freud started it by speculating about early childhood sexuality. These theories have increasingly found their way into mainstream psychology during the last two decades, but they remain speculation and have no sound scientific basis. Same applies to gender ideology. Reply

    Well, whatever the reason may be for someone identifying as "trans" or "cis" in a gender context, what is unscientific about it? It is merely a descriptor for what kind of state they identify as. And science is nothing if not description first and foremost. Reply
  • mapesdhs - Wednesday, January 10, 2018 - link

    It's unscientific in a gender context because people who "identify" in that way are doing so based on *feelings*, which is not an argument. Reply

    Collecting data based on self-reporting just stands at the beginning of a scientific inquiry. Insights should be based on proper scientific evaluation of the data, not on inferential jumps. The vast majority of human beings develop happily with their gender identity in accordance with their biological sex, but gender ideologists claim: it is a fact that dna only determines sex but not gender; a transgender state of mind is a natural state of identity (and healthy - if it was not for distress caused by the wrong body!); the correct response is affirmation by all involved (friends, family, teachers, physicians etc.); in the case of young persons it is desirable to propose puberty blockers, - without any conclusive scientific evidence to prove any of those claims. This is now very much off topic, so I will stop now. If you are interested in this topic, you could start a thread in an appropriate section of the forum, but you may find that technically and scientifically minded contributors show little support for gender ideology.
