The new Microsoft Surface Laptop 3 has a big brother – a 15-inch using an AMD Ryzen 3000-series 5-3580U or 7-3780U System-on-a-Chip.

Moving the Microsoft Surface Laptop 3 – 15-inch to AMD represents a significant departure for Microsoft although it uses AMD processors in the Xbox. It’s a big win for AMD to have its processors in such a mainstream device.

Does AMD make a vast difference over Intel? The tests indicate no. Microsoft Surface Laptop 3 – 15-inch is an excellent product with no downsides. And Surface remains the best 3:2 ratio screen option for those that favour productivity over games.

But Intel fans are going to look at some of the Intel i5/i7/i9 options on offer from Dell, Acer, HP, Lenovo and more at competitive prices. Or settle for the Microsoft Surface Laptop 3 – 13.5-inch with 10th generation Core i5-1035G7 or i7-1065G7 processors.

So, if you don’t mind AMD (and you shouldn’t) then read on because Surface ‘anything’ is Microsoft’s licence to give us what it feels we need.

Microsoft Surface Laptop 3 – 15-inch AMD Ryzen 5-3580U Model 1873

Specs as tested

  • 15-inch, 2496 x 1664 , 201ppi, 3:2 display
  • AMD Ryzen 5 3580U with Vega 9 graphics (Option Ryzen 7-3780U with Vega 11 Graphics)
  • 8GB DDR4 and 256GB PCIe SSD
  • One-year limited hardware warranty
  • Website here

Price (current special)

  • 8/256/Ryzen 5 $2124.15
  • 16/256 Ryzen 5 $2379
  • 16/512GB Ryzen 7 $2931

If you are a power user, then buy the 16GB version because the ram is not upgradeable. Storage is immaterial as you can get high-speed external 256GB SSDs for under $100.

My first impression

Big and black – did I mention black with a vast touchpad and deck to rest my weary palms. I am glad that they don’t offer that sissy Alcantara faux suede on a ‘man’s machine.’ Give me aircraft-grade, milled aluminium any day.

In reality, it is a perfectly scaled up 13.5-inch Laptop 3. As usual, the Microsoft boffins have put a lot of thought into this new design. For example, the screen is a one-finger lift held down by magnets and lifted from a very slight overhang.

The Surface Laptop 3 display opens about 150° and supports the Surface Pen although I venture that it’s a little harder to use on a clamshell than on the Surface Pro.

In all its one of the sexier all black, slabs I have ever seen.

Why a laptop?

Me, I prefer x360 hinges or the Surface Pro tablet with a kickstand. But some feel more comfortable with a traditional clamshell-style laptop – something that can sit on your lap or desk.

But importantly it is part of the Surface range including the Pro, Pro X, Hub, Studio and more – all with unique Surface styling cues and that almost unique 3:2 ratio screen.

Surface family

Screen – EXCEED

It is a 15-inch, 2496 x 1664, 201ppi, 3:2 ratio, PixelSense (marketing term), touch and pen capable screen.

In reality, it is a Sharp LQ150P1JX51 panel made especially for the Microsoft Surface Laptop 3. It is Sharp factory calibrated to 100% sRGB, Delta E <1 and also offers an enhanced mode (saturated). That equates to about 64% Adobe RGB. Unfortunately, you can’t adjust the calibration using a Calman camera, but you can find various profiles on the web to change them.

A few very minor quibbles. The laptop screen has a tad of ‘touch wobble’, and a glossy finish impairs daylight readability. The 383 lumens are bright, but we measured .4 nits black, reducing the contrast to 1100:1 (claim 1500:1). Now tests are tests, and for most users, this is a great screen.

We know Microsoft use some secret sauce to get such a responsive touch screen – iFixit has revealed that it uses its own designed ICs – X904169 and X904163 based on N-Trig digitiser technology.

But it would be nice if the next Surface Laptop 4 moves towards wider AdobeRGB and DCI-P3 gamut displays, HDR and get rid of those bezels – ‘just saying is all’ as its competitors are ahead there.

Processor – PASS for productivity but FAIL for serious gamers

Microsoft and AMD have developed a special version of the AMD Ryzen 5 and 7 Series 3000 processor. Let me repeat that there is no downside at all, and the processor is a good fit.

Microsoft Surface Laptop 3 – 15-inch AMD Ryzen

The AMD Ryzen 5-3580U with Vega 9 Graphics (and Ryzen 7 – not tested) is a four-core, eight-thread 2.1/3.7GHz CPU with a default TDP of 15W and goes up to 35W under load.

It is an important move for AMD and Microsoft. In part that is to be ‘exclusive’ to Microsoft Laptop 3 – 15-inch and in part designed to suit the ultra-slim form factor. It obviously works well as in a 15 minute, 100% load throttling test it did not overheat or drop speed.

PassMark single/multi scores are 1684/7429 (based on five samples) which puts it on par with the older AMD Ryzen 5-2500U. It is about 15% slower than an Intel Core i5-8365U. So, it’s not a powerhouse SoC.

The Ryzen 7-3780U is about 5-10% faster (depends on the benchmarks used).

In fact, respected NotebookCheck says it is 13% slower than the Intel Core i5-1035 in the 13.5-inch counterpart.

But we have to warn you that being over technical overlooks user scenarios. This chip more than meets the needs for office productivity and content consumption.

CPU Tests

  • Fan: 32 to 42dB under load
  • CPU Heat: 33-79°
  • Outside heat top/bottom: 43/50° under load
  • Power – 3W idle and 25W+ under load
  • Throttling: None evident at 100% load for 15 minutes – just a louder fan

Note: There is a significant difference in performance on 240V power versus battery.

GPU – PASS for productivity and content but FAIL for gamers

AMD Vega 9 means nine cores. The 3:2 screen is difficult for gamers anyway. Add that together, and the Surface Laptop 3 has a pretty respectable GPU for productivity and content consumption.

RAM/Storage – PASS with caveats

A pet hate is that the 8GB DDR4-2400 is soldered onto the motherboard (so order 16GB).

The PCIe NVMe M.2 2230 (small factor) SSD comes in 128GB, 256GB, 512GB and 1TB (although Microsoft currently has no stock of the larger sizes). The usual SSD is M.2, 2280 so this smaller one is harder to find.

The SK Hynix BC501 HFM256 is relatively slow at sequential read/write 2000/815 Gbps (compared to other premium SSDs at over 3000/2000).

Another pet hate is small print. It claims the SSD is replaceable. ‘Removable solid-state drive (SSD)6 options: 128GB, 256GB, 512GB, 1TB’

Footnote 6 says: Hard drive is not user removable. The hard drive is only removable by skilled technician following Microsoft provided instructions.

Ports – PASS with caveats

  • USB-C, 3.1 Gen 1, 5Gbps with PD 2.0 45W and DP
  • USB-A, 3.1, Gen 1
  • Surface Ribbon for power and data
  • Combo 3.5mm audio

You are going to need a dongle or a dock for any expansion. 5Gbps will run 1 x 4K@60Hz or two x 1080p@60Hz.

Microsoft Surface Laptop 3


Qualcomm QCA6174A Dual-band 2 × 2 802.11AC with MU-MIMO. 866Mbps at 2m from D-Link AC5300 router but does not hold steady varying from 556MBps

Bluetooth 5.

Note that the 13.5” has Wi-Fi AX

Battery – PASS

The same 45Wh battery is in the 13.5” and 15”. A 15V/4A 60W Ribbon Charger has a 5V/1A USB-A port.

Microsoft claims 11.5 hours real-world use, but the Windows defaults are heavily optimised towards battery life. In reality, you need a better default balance of screen brightness and performance. We expect about 8-9 hours of light use.

Quick charge up to 80% in an hour (claim) and we tested a full charge two hours (1.5 hours claim)

  • Light use – 9 hours
  • Video loop 8 hours – two hours less than Laptop 2 Intel core i5-8250U
  • PCMark 10 heavy use – 6.5 hours
  • Full load – 3 hours

Keyboard/trackpad – PASS

The Surface Laptop 2 set the standard with 1.5mm throw and 50g actuation. This time around the keys are more recessed into the deck and throw is 1.3mm and 40g – we consider it a backwards step.

However, it still provides a great typing experience with little bounce. It has three stage-backlighting.

The oversized trackpad supports 10-finger touch, e.g. pinch, zoom, etc., – it is responsive and great as it will move the cursor from top right to bottom left in one swipe obviating the need for a separate mouse.

Sound/Camera – PASS

  • Volume: 80dB
  • High Bass creeps in at 125Hz and builds gently to flat low range mids from 400Hz to 12.5KHz.
  • Bright Vocal sound signature. Overall quite pleasing.

It will also decode Dolby Atmos to the speakers and output to BT or 3.5mm headphones.

720p camera (no privacy shutter) sits alongside depth sensors that allow you to log in almost instantaneously with Windows Hello

If you are not familiar with Hello, it is all about using your face to log in. The unit has a special IR camera alongside the web camera that does facial recognition and checks the image is from a human rather than a photo. While it is not mandatory to use it – give it a go, and you will find it is as fast as typing in a password or pin. I had 100% success with this.

Case/Build – PASS

It is 339.5 x 244 x 14.7 x 1.54kg in matte Black (as tested, metal), and Platinum (metal)

Catch: it is a lot squarer than 16:9 ultra-books, and many of our 15” slip cases did not fit.


Surface Pen

Surface Pen (4096 pressure levels) $139.95
 Surface Dock (add two monitors, 4 USB-3.0 ports, etc.) $299.95
A variety of adapters – check here

Serviceability – PASSable

The bottom panel is removable – see iFixit Teardown, and it scores 5-out-of-10 for repairability.

Microsoft Surface Laptop 3 – 15-inch AMD Ryzen

But, and this is a pet hate of a reviewer – Microsoft makes it impossible to set up initially as a local account. You must have MS account to install and then can swap to local, but by that time your MS Photo and details are firmly entrenched into the system, and your smiling visage shows up in MS Edge as logged in.

GadgetGuy’s take – Microsoft Surface Laptop 3 – 15-inch AMD Ryzen is Ryzen to the top!

Finally, the Surface Laptop 3 comes of age with the right proportions, a fantastic PixelSense screen and pen support (albeit an expensive optional extra). And no more Windows 10 S either!

We like the AMD SoC, but it is not up there with the Intel 10th gen in the 13.5”. Still, it is all about what you can do with it and for office, productivity and content consumption it is great.

But some other things just don’t thrill us. With USB-C 5Gbps only it is hamstrung as a dual-screen device. It seems hobbled compared to its 13.5-inch brother – no Wi-Fi AX, slower speeds than the Intel 10th gen processor etc.

And there are some terrific, more fully-featured Ultra-lights out there with 9th and 10th Gen Intel Core and Thunderbolt 3.

Despite that I suspect Microsoft will sell heaps – it is pretty good – not superb.
