Conclusion: Good for Mainstream but Not for Enthusiasts

For the second straight laptop review, what started out as a system with a lot of promise ends up falling short of my expectations. For many users, the Samsung Series 7 will work very well, but enthusiasts or other folks that tend to push their hardware to its limits may end up less impressed. Let’s start with the good though, as there are many areas where Samsung gets things right.

First off, the Samsung Series 7 is a nice looking notebook (IMO). It’s a neutral silver color with a relatively thin profile, and there’s no gaudiness or bling to be found. I can’t speak for everyone, obviously, but this is the type of laptop I’d feel perfectly comfortable using in public—something I can’t say for some of the other notebooks I’ve reviewed over the years. It’s unlikely to start conversations, but sometimes that’s exactly what you’re trying to avoid.

Another good element that’s near and dear to my heart is the keyboard layout. I type—a lot, as you may have noticed [Ed: 8000 words and counting…]—so having a comfortable keyboard is an absolute must in my book, and a proper keyboard layout is only slightly behind that requirement. If I were to pull out my own credit card to buy a laptop/notebook, there are basically two options (in terms of layout) that I’d be happy with. One of those is the Samsung Series 7 keyboard, while the other would be for a smaller 13.3” or 14” laptop and it would look like the Dell Vostro V131 keyboard. Note that I’m not talking about chiclet vs. other key styles here; I’m only talking about the layout—if we’re discussing keyboard styles, I think the older Dell Latitude and Lenovo ThinkPads were better, though they don’t look quite as catchy. So that’s another area that I really like on the Series 7: the keyboard layout (though I still miss the “context key”).

The final item I want to highlight is the display. I’ve seen less expensive Samsung laptops with pretty weak displays—just like pretty much every other brand. For this particular unit, the display is definitely one of the better options out there. You get the increasingly common 1080p FullHD resolution, but more importantly for me is that you get good contrast, good colors, and an anti-glare (matte) coating. The maximum white level is decent, and while I’d like to see closer to 400 nits in an ideal world, 300 nits is sufficient for use in well lit areas thanks to the matte surface. IPS displays with true 8-bit color are still better in my opinion, but this is about as good as you can get from TN panels. Too bad everything has gone 16:9, as I would prefer 16:10, but that’s probably beating a dead horse.

With all the good elements, there’s one major flaw that’s hard to overlook: thermals and potential throttling. Even if you live and work in an environment that never gets above 70F/21C, putting a maximum load on the CPU, GPU, or especially both simultaneously will quickly result in less than maximum performance. I’ve pounded on other notebooks with similar stress tests, with varying results. Dell’s XPS 15 fell flat on its face and has yet to get up, despite an updated BIOS; meanwhile ASUS’ N56V series laptop handles the load quite well, with no throttling evident, but with CPU temperatures that are rather alarming. Given that the Dell and Samsung notebooks are both quite a bit thinner and have exhaust vents behind the LCD hinge, there’s a relatively strong correlation between the designs and the results. Of course, the ASUS N56V that I have also sports a slower GT 630M DDR3 GPU (and a faster i7-3720QM), and that’s likely playing a role, not to mention that the CPU does hit a blistering 104C—but it never actually throttles in my experience and I haven’t had it crash yet [Ed: Knocks on wood].

Despite the fact that the Samsung Series 7 didn’t quite handle our stress testing as well as I would have liked, the limited throttling isn’t a complete deal breaker. In most games, the CPU will actually run at its rated 2.3GHz (or higher) speed without difficulty, and while temperatures are still higher than we’d like at least games run quite well without requiring the use of a tool like ThrottleStop. Incidentally, I did do some testing with ThrottleStop and was unable to improve on the initial results, which is why I didn’t have a lengthy section discussing performance while using the utility. The updated BIOS manages to hit a pretty consistent 2.3GHz on the CPU while keeping the GPU clocks at 725MHz, and the result is performance slightly better in some cases than what we’ve shown in our charts. It’s still possible that Samsung could further improve performance in worst-case scenarios with another BIOS update, but short of pathological workloads most people should be fine with the latest BIOS revision (though tweaking the fan speeds to run at a higher RPM might still be useful if it can be done).

If the appearance, keyboard, and LCD are good aspects and the thermal performance is a bad aspect, in the middle we have the overall performance and build quality. The Series 7 is definitely built better than budget laptops, with an aluminum palm rest and a reasonably sturdy chassis. However, it’s not as rigid (or heavy for the size) as a machined aluminum chassis would be, and likewise it’s not at the level of higher class business laptops. It’s built well enough that I wouldn’t complain about the quality, but it’s not so amazing that it warrants high praise. As for performance, the CPU is fast enough for all but the most demanding users; the GPU on the other hand is a step down, with good enough performance for moderate detail 1080p gaming but not enough to really tackle high detail 1080p gaming in many titles. I can live with both of those components, but the HDD + SSD cache configuration ends up being noticeably slower than I’d like. While a larger caching SSD with Intel’s SRT would be better, what Samsung and other vendors really need to do is to simply use a minimum 128GB SSD for the OS and primary applications. Given Samsung’s position as a quality SSD manufacturer, this should have been an easy upgrade that got lost in the pursuit of lower BoM costs and/or higher profits.

The result of the above is that Samsung straddles the fence and ends up with a device that has premium pricing and looks, but it doesn’t always feel or perform like a premium product. If you’re mostly interested in getting a good display with a nice keyboard and an attractive notebook, the Series 7 has a lot going for it. Obviously it’s not going to appeal to the thin and light crowd, but I know users that prefer larger LCDs on their notebooks; that’s exactly the type of user Samsung is targeting with the Series 7 NP700Z7C. On the other hand, if you’re after something that can function as a mobile workstation, or if your friends and family refer to you as a “gamer” or “technology addict”, there’s a good chance you’ll end up disappointed with the throttling/performance; we also have concerns about the long-term prospect for the notebook, as cooling tends to become more of a problem with age. For such users, we recommend looking at other alternatives, and my top bang-for-the-buck notebook right now continues to be the ASUS N56VZ. $1000 (plus shipping) will get you essentially the same level of performance as the Series 7 with another good LCD (better in some ways), for $400 less. You could then take that $400 and buy a roomy 512GB SSD, or go for something a little less extreme like a $200 256GB SSD and you’d still end up way ahead on performance and pricing.

    It seems to be a PERFECT laptop if the user replaces the HDD with a SSD, plugs a gaming mouse and uses it in ACed room.

    I think the biggest drawback of this laptop is the lack of secondary HDD bay. Many laptops now provide mSATA slot where user can easily put 128GB boot drive (and they cost as low as $100 nowadays too) while keeping ~1TB data drive. With a single 2.5" bay such setup is not possible. Small SSD cache is just a gimmick and generally not comparable to true SSDs. And they should provide slower 35W CPU option as well - which should help overheating a bit.

    Anyway I think this laptop is actually one of the best 17" laptops out there for general public, and one good replacement for 17" MBP which is now discontinued.

    Hi Jarred,

    thanks a lot for your review. Since we cannot trust specification sheets anymore when we choose a laptop, the work of good reviewers is essential.

    If manufactures decide that performances don't really matter, we will gladly spend more on the monitor and less on the CPU/GPU, or we will buy tablets instead of notebooks.

    I hope you'll improve your testing methodology about the impact of the cooling system on the performances, because if when a laptop "falis" the stress test, it "doesn't really matter", then the stress test doesn't really matter itself.

    I'd like to suggest testing an heavy CPU load with the GPU turned on but idling. This is the Adobe Premiere Video export scenario or generic cpu load using an external monitor. My XPS15 throttled badly with the A04 bios after 2 min during this test, because the heat from the CPU triggered the GPU temperature threshold. Manufacturers should find a clever way to balance TDP than temperature thresholds.

    Also, please keep in mind that a CPU at 1.2GHz has a lot of impact on the gaming experience, much more than average fps shows, and that a GPU continuously throttling between 800 and 200 mhz has higher average fps than a GPU fixed a 400 Mhz, but it gives a lot worse gaming experience.

    No, CPU power rarely affects gaming experience, as most of the games are now developed multi-platform and ivy bridge@1.2Ghz is still WAY better than any console out there. On the other hand, GPU power directly affects framerate.
  • .Hg. - Friday, August 17, 2012 - link

    It does, I experienced an awful control lag with Assassin Creed II and Prince of Persia.

    Games that are not properly multi-threaded will suffer the low frequency. Ivy Bridge can't do miracles.

    And games that are properly multi-thread will show much greater power absorption even at low frequency because of the higher load, and if the cooling system is not good, the system will try to reduce the GPU frequency.
  • nerd1 - Friday, August 17, 2012 - link

    No, I don't think such an ancient game can load CPU to maximum. It ran fine with core 2 duo processor, which has much lower power-per-clock than new ivy bridge processor. The only cpu-consuming task I can imaging for computer game is heavy physics simulation, which is done with GPU now.

    It's not that the stress test doesn't matter at all, but I would say it's not a make or break situation for most people. Obviously (I would think, but maybe not?), a laptop that runs cooler right now should hold up better over the long term than a laptop that is hitting thermal limits right from the start. The XPS 15 is horrible when it comes to throttling; the Samsung is only throttling under extreme loads -- in a rather warm 80-85F environment, I might add (curse my lack of AC).

    If you happen to live in a place like AZ and take your laptop outside where it's 105F, and then you put a 100% load on the GPU and CPU, I'm not sure any laptop would cope with that sort of testing without throttling. It's the way things are supposed to work. The real question -- and it's a question that's difficult to answer -- is how much a laptop can handle before it starts to throttle. That's what the stress test is there to help evaluate.

    If you need a notebook that can run both CPU and GPU at 100% simultaneously in a 70F AC regulated environment, that's fine. In that case, the Series 7 falls short, but it's still a lot closer than the XPS 15. If you're a typical user that plays games, on the other hand, then that's the metric you should look at, keeping in mind that certain titles will likely stress the CPU/GPU more than others.

    I think the only laptop that can withstand full load for a long time is thick gaming laptops.
  • seapeople - Friday, August 17, 2012 - link

    Jared has it right here, the only way to really fail a stress test is for the computer to overheat and brick itself. Everything is a gray area.

    If the Samsung did so poorly that it throttled instantly to ultra poor performance levels the moment a game was started *cough Dell cough* then it would deserve a thrashing, but it handled high performance gaming with only limited throttling issues, so therefore deserves better than a unilateral no vote.

    Besides, if the computer throttles during gaming too much to suit you, then you can reduce the settings/CPU speed to suit. You would lose performance, sure, but we're still talking about something that would destroy ultrabooks or entry level graphics cards.

    My company has bough four samsungs (expensive, supposed high end series 9 ultrabook). Three of them had problems. Terrible built, mega fragile.
