MSI’s Ultra Slim X370: Bigger Isn’t Always Better

First up is the MSI X370, an ultra slim 13.3” portable. The base model we received for testing measures less than an inch thick, making it comparable to the MacBook Air in some ways. Where it doesn’t compare is in performance or industrial design, as MSI is still using glossy plastic just about everywhere, and the frame doesn’t have the feeling of solidity and durability that you’d get from a MacBook Air or Pro 13. Here are the basic specs for our test system.

Other than the hard drive and the battery, a few differences in port selection and location, and coming with 1x4GB DDR3 memory, the X370 has the same basic specs as the HP dm1z. Keep in mind that despite having a single 4GB SO-DIMM, since the Brazos platform uses a single 64-bit memory channel there’s no advantage to two memory slots other than expansion. Total system memory bandwidth is just 8.5GB/s, which could be part of the reason some games struggle to reach playable frame rates. The other part of the reason is that, while the Bobcat core can easily beat up on Atom CPU in terms of performance, it’s no match for faster architectures like Core 2 or K10—in fact, even a 1.3GHz CULV is faster than the E-350. What you end up with is significantly better than Atom performance (particularly on the GPU side), with nearly Atom levels of battery life, and good (for a netbook/ultraportable) graphics. Or put another way, you get a much better IGP than Intel’s GMA 4500MHD that was commonly paired up with CULV processors, with similar power requirements but lower CPU performance.

One other area where MSI’s X370—along with most other Brazos laptops—beats Atom is in the networking options. Like the HP and Sony, we get Gigabit Ethernet along with the standard 802.11n networking. Considering there’s no internal optical drive and I like to install games and applications over my GbE network, I definitely appreciate the extra $0.25 MSI spent here. On the other hand, it comes with just two USB 2.0 ports, both on the right side; a third (or even fourth) on the left would have been nice to get.

Moving on to the design and construction, the very thin body is comparable to Apple’s MacBook Air on a superficial level. Of course, outside of the thinness, there’s very little that the two platforms share in common. The X370 is predominantly plastic in construction, which is similar to the basic MacBook, only you get black with a pattern instead of glossy white. The MacBook is also slightly thicker and weighs more, but it comes with an optical drive and larger 63.5Wh battery by default. As we mentioned up top, performance is also heavily in favor of the MacBook, even with an aging Core 2 P8600; the GeForce 320M IGP is quite a large step up as well, even if it lacks DX11 support.

There’s another catch with the size and dimensions: the ultra slim form factor is only there if you use the 4-cell battery, which checks in at just 32Wh; MSI shipped us an 8-cell 64Wh battery wedge as well, which as expected doubles (slightly more) the battery life but bumps the thickness up to nearly 2” at the rear. Ideally, we’d like to get the higher 64Wh battery capacity while maintaining the slim form factor, but as far as protruding batteries go this 8-cell unit isn’t bad. It’s flat and wide, so you can still comfortably use the X370 on your lap or other surfaces. Still, there’s no sense in shipping a laptop with a 32Wh battery these days; it may last “long enough” for most users initially, but you know that a year or so down the road it will only hold half of its charge and suddenly you’re dealing with a 1-2 hour battery life at best. Spending $100 extra for the larger 8-cell doesn’t sit well either, considering the target market. Sony also goes with a smallish 38Wh battery, but HP packs in a 55Wh battery. Notice a pattern yet?

The keyboard works reasonably well, and while MSI doesn’t use the entire width of the chassis for the keyboard, it’s comfortable enough to use for hours at a time. There’s a small amount of flex if you type really hard, but nothing that causes me any concern. The touchpad also works well, with the standard multi-touch features. What doesn’t work well are the mouse buttons; MSI uses a rocker-style chrome (plastic) button, which may or may not please your sense of aesthetics. My issue with the buttons is that they don’t register very well, particularly the right button, where you have to put some thought into pushing it hard enough and in the correct spot. However, in disassembling the X370 we discovered the real problem with the right button: the button fails to register unless you put some flex on the PCB beneath the touchpad. Remember that this is an engineering sample; we’ll assume any final models will have functioning hardware, but we’d still prefer discrete left and right buttons.

It practically goes without saying that the LCD panel is mediocre, with limited vertical viewing angles, mediocre colors, and a poor contrast ratio. If you need to get at the internals—for example, if you want to upgrade to an SSD or access the memory slot, though the 4GB unit we received will likely never need the latter—you run into another problem: there’s no quick access to the internal components. Instead, you have to get through the keyboard (secured by three clips), and then remove the top plastic panel (including the palm rest, but strangely enough not the chrome plastic border). It’s not particularly difficult, and you can safely ignore the “Warranty Sticker – Void if Tampered” label on one of the screws in the battery compartment, as you don’t need to remove those screws. All of the important screws (seven of them) are under the keyboard.

Somewhat perplexing is that after disassembling the laptop, I had some real difficulties getting the front plastic clips (near the touchpad) to snap back together properly. Ultimately, I had to remove the touchpad rocker button so that I could get the two clips underneath it to snap into place. It was an annoying process and the numerous plastic clips would very likely break if you were to access the internals more than a few times, but this should only be necessary if you want to replace the HDD. Of course, we want to do exactly that as an SSD will definitely improve the overall experience, but that’s another story.

Assuming the MSI X370 is priced similarly to the X350, we have some serious concerns with the product line as a whole. The X370 doesn’t have the greatest build quality as the whole laptop feels a little cheap, and the difficulty of upgrading the components doesn’t help, but it comes reasonably equipped. Unfortunately, the X350 had an MSRP of $800 for a CULV design, which is about $200 more than we’d be willing to pay for the overall build quality and package. If the MSRP of the X370 is indeed $750, that’s once more at least $200 more than we can recommend. Dustin feels the Sony VAIO’s MSRP of $600 is too much (and it is!), but anything north of $650 for a plastic-shelled E-350 laptop is ludicrous. At $700+, the MSI X370 will be DOA.

    Is the Vaio upgradable to 4GB of RAM? Because it uses a 32 bit system. And so, can you install the 64bit version? Will 4Gb have an influence on the grapgic part? Because it uses chared memory.
    And is the CPU easy to replace with another one?
    For the moment, it has no much sense, because it is the best processor for its socket I think.
    Are there any new CPU's planned for this socket?

    wondering if you had a pdf guide or followed a video. My 1 yr old dropped my 2 month old x370 grrrrrrrrrr and now the front tabs have snapped up and the little chrome bar underneath the touchpad does not work.

    Thanks very much!
