Wireless

If there’s been an Achilles heel of the Surface lineup, it has been Microsoft sticking to low quality wireless adapters. Surface devices have almost exclusively utilized Marvel AVASTAR wireless, which has been not only slow, but unreliable. Over the years, the reliability has improved, but the overall solution was never up to where an Intel wireless adapter would perform in terms of both performance and reliability. The only time the Surface team has leveraged something other than Marvell was with their LTE devices, which would use a Qualcomm wireless adapter. Unfortunately, it wasn’t really any better than the Marvell one.

Luckily that has changed for the current generation of Surface devices. For the Intel-based devices, Microsoft has adopted Ice Lake's semi-integrated Wi-Fi 6 (802.11ax) solution. Unfortunately AMD doesn't offer an equivalent here, so Microsoft is using a Qualcomm wireless adapter in the AMD-based 15-inch Surface Laptop 3.

WiFi Performance - TCP

The results are not great. While there haven’t been any reliability issues at all, the performance of the Qualcomm wireless was frankly terrible. It is almost 2020, and we have wireless networking solutions that can reach over 1 Gbps with just a 2x2 configuration, but the 15-inch Surface Laptop 3 achieved a meager 313 Mbps.

Audio

Microsoft has outfitted the Surface Laptop 3 with Omnisonic speakers featuring Dolby Audio Premium, and while the pairing does not get excessively loud, the sound quality is fantastic, with much better low-end than you’d get on most laptops of this size.

At around 76 dB(A) measured one inch over the trackpad, there’s enough volume for most situations, and the improved sound quality is a great trade-off over really high dB speakers with no range.

There are two far-field microphones as well, enabling Cortana interactions if desired.

Thermals

The advantage of a larger laptop like the 15-inch Surface Laptop 3 is that it should not have much of an issue cooling a 15-Watt TDP, and the laptop was stress tested to find out if that was the case.

Interestingly the CPU on its own only pulls 9-10 Watts under sustained load, with a brief peak of a hair over 15 Watts. This is well under a typical Intel 15-Watt CPU which can pull well over 30 Watts for burst and sustained power draws can be over 15 Watts if the cooling system can handle it. Despite the lower than expected power draw under load the CPU is still able to maintain 3 Ghz or higher.

The cooling solution is very solid, and unless you are really working the laptop it stays silent for most of the time. Meanwhile if you do need to use everything the laptop has, the fan only gets up to 46 dB(A) measured one inch over the trackpad, which is not very loud. The tone of the air movement is a bit harsh though, but never gets to be a problem.

Software

As is typical of a Surface device it comes with very minimal software. There is the normal Windows apps, some of the Windows crap-ware that all machines ship with, and the Surface App, which lets you adjust the pen pressure, see the battery of connected Bluetooth devices, such as the pen, and get support if needed.

One thing that is absent though is the AMD Software Center, so you can’t adjust any of the typical AMD settings. Trying to download this from the AMD website will result in a “no valid hardware found” message. This is unfortunate, since you won’t be able to easily disable things like AMD’s Vari-Bright, which automatically lowers the screen brightness on battery. AMD let us know that they won’t be bringing this to the Surface Laptop 3 either, so if you are a fan of the AMD Software Center, don’t expect it anytime soon on this AMD powered device.

    Ultimately, it's not a gaming laptop - and the resolution is higher than most, which compounds the issue if you want to run native. But some of game results are also a little misleading.

    Realistically you'd probably *not* run Civ on Ultra on this hardware unless you don't care about FPS. Memory bandwidth will be hurting. I'd take native res and lower settings to reduce texture size/particles - which might also speed the game itself up, not just its rendering.

    2400Mhz DRAM for AMD variant is so unfair.
  • TheinsanegamerN - Tuesday, October 22, 2019 - link

    This is a limitation imposed by AMD. Go look at AMDs spec page, they only support 2400.

    So outside of the meh WiFi and reduced battery life, this is a solid mid range CPU laptop with some nice GPU chops.

    Definitively a candidate for purchase if one spends more time in the desk rather than mobile and life on Windows.

    Kudos to MS for starting to use AMD chips. I think the overall performance is good and if you include the GPU performance in your consideration, I would say the performance of the platform is on par with Intel's. The only letdown I see is battery life. I feel that Intel still holds the mobile crown for this particular reason.

    This is a great option for work and games. I work for https://technovolume.com/, where I was given this laptop. Every day is so much easier for me, it's great!

    The whole ultrabook idea is no longer valid with the benifit vs costs.
    Was a user of surface book 1 and surface book 2, but recently switched back to a Thinkpad P1 Gen2. I get more flexibility for the P1 with optional 64GB ram, 2x2TB SSD and lower costs. Mobility is almost the same, the surface book 2 is 1.632kg with 0.381kg of power supply. With the P1, the weight is 1.718kg but I can use the 65W lenovo thunderbird power supply which weights less than 0.15kg. Not to mention the P1 has 4core/6core/8core options for the processor and a better Nvidia graphics card.

    You can make similar argument with the Surface Laptop 3 15inch.

    It is so hard to understand this text. Why u just cant write easier? "Convertible functionality" - are you serious? What it even means? Please just use regular words. It is so hard to read this.

    Great work & great post. I am really inspired by it
