Samsung Galaxy Book S Laptop Review: Lakefield with initial problems

Brighter display. Samsung now also offers its compact Galaxy Book S with an Intel processor. Compared to the ARM model, you get better compatibility with apps, but in return there is no LTE modem and the battery runtimes are also shorter. We checked if there are any other differences between the two models.
Andreas Osthoff 👁, Stefanie Voigt (translated by Andreas Osthoff),

We recently reviewed the Samsung Galaxy Book S with the ARM processor, and the South Korean manufacturer now offers its compact ultrabook with an Intel processor. It is the brand-new Lakefield hybrid chip, which is once again completely passively cooled. However, the Intel model does not include an LTE modem in all regions anymore, and the battery runtimes are also shorter. The x86 does improve the compatibility in return. The two versions are almost similarly priced, so we want to find out which device is better.

We have purchased our unit from Samsung's official online shop, so it is a regular retail unit and not a selected press sample from the manufacturer. For a price of 1129 Euros (~$1275), you get the Intel Lakefield processor, 8 GB RAM, and 256 GB storage. The 1080p touchscreen is basically identical as well, but Samsung equips the Intel SKU with a special Outdoor+ mode, which is supposed to increase the brightness to 600 cd/m².

The case, the ports, the speakers, as well as the input devices (except for the color of the background illumination) are identical to the recently reviewed ARM version. We will focus on the differences of the two models in the following review and take a closer look at the new Intel processor.

Note: The German review unit was not equipped with an LTE modem, but it is included in other countries. The review sections regarding the missing LTE modem are therefore not representative for all regions.

Case - The Intel SKU is also below 1 kg

The Intel version of the Galaxy Book S is even slightly lighter at 940 grams, but this is not noticeable even in a direct comparison. Together with the compact power adapter (91 grams/3.2 oz including USB-C cable), the total travel weight is still just slightly above 1 kg (~2.2 lb).

Connectivity - Galaxy Book S with Wi-Fi 6

The ports are identical to the ARM version of the Galaxy Book S. There is a USB-C port on each side (USB 3.1 Gen.1 w/ DisplayPort-Alt), which can also be used to charge the laptop. You also get a 3.5 mm stereo jack and a microSD reader.

The maximum transfer rate in combination with our reference card from Toshiba (Exceria Pro M501 64 GB UHS-II) is 82.4 MB/s, so it is identical with the ARM model. The average transfer rate when you copy pictures is a bit lower at 63.9 MB/s.

Samsung does not ship the German model with an LTE modem, so one major advantage of the ARM SKU is gone. In return, customers get a slightly faster Wi-Fi 6 module from Intel (AX200), but the transfer rates in combination with our Netgear router (Nighthawk AX12) are below our expectations. The results are better compared to the ARM Galaxy Book S, but most users will probably not notice the difference.

Input Devices - Keyboard illumination still hardly usable

Keyboard illumination on full brightness
Keyboard illumination on full brightness

The input devices are identical to the recently reviewed ARM model. Our test unit in Earthy Gold, however, does not have a green keyboard illumination, but a white one. The basic issue is still the same though, because the backlight is controlled by a sensor, which is sitting in the lower right display bezel. The sensor will only activate the illumination when it is almost pitch black, and we could not activate it in dim environments. The visibility of the keyboard is not perfect due to the color, either, and we would have wanted a manual control in many situations. The illumination could also be a bit stronger. Samsung should definitely fix this issue.

Display - Outdoor+ Mode is much brighter

Subpixel array
Subpixel array

A quick look at the specs suggests that Samsung uses the same 1080p touchscreen, and our measurement results are also very similar for the most part, but there are two important differences: The Intel SKU supports the so called Outdoor+ mode, which increases the brightness to ~650 cd/m². We cannot detect any PWM flickering, either, which was the case on the ARM Galaxy Book S. Therefore, it seems to be a different panel (we could not find out the exact panel-ID on the ARM model). Similar to the ARM model, the subjective picture impression is very good. The integrated brightness sensor only controls the keyboard illumination; the screen brightness cannot be adjusted automatically.

Note: Samsung says that the Outdoor+ mode will increase the brightness significantly, which also increases the power consumption. The Outdoor+ mode is also automatically deactivated when you turn off the screen or when you close the lid, for example. You always have to activate the mode manually, so we use the results without the Outdoor+ mode for our rating (for both the power consumption and the battery runtime).

* ... smaller is better

The average luminance is once again around 350 cd/m² and the contrast ratio is very good at 1200:1. There is a slight blue cast out of the box, and the color temperature is a bit too cool as well. Contrary to the ARM model of the Galaxy Book S, it was no problem to calibrate the display this time, and the results improved significantly. The slight color cast is completely gone, and the color deviations are also lower. Only 100% blue is still above the important mark (3). You can download the calibrated display profile in the box above.

The small sRGB color gamut is almost covered completely, in combination with the low color deviations you can also use the display to edit pictures/videos in the small color space. We also checked the screen with the Outdoor+ mode, and the much higher brightness does not impact the subjective picture quality. The black value suffers a bit, but the overall contrast ratio is still around 1200:1.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey

In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 85 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9599 (minimum: 5 - maximum: 142900) Hz was measured.

You can see the difference between the standard and Outdoor+ mode when you use the laptop outdoors, but the reflections on the glossy screen are still a big problem and it is not easy to capture the difference between the two modes on camera. You should still avoid reflections from light sources or bright surfaces if possible.

Performance - Galaxy Book S with reduced TDP

The Intel Lakefield hybrid processor is brand-new, and many tools still have problems to show accurate data. In theory, the Core i5-L16G7 has a TDP of 7 watts (9.5W Burst). According to our information from Intel, however, Samsung reduced the PowerLimit 1 from 7 to 5 watts (PL2 still at 9.5W). This means the following results are not representative of the performance of the Lakefield processor if it runs with the specified 7/9.5 watts.

Note: Shortly after the original German review of the Galaxy Book S was published, we got an official statement from Samsung regarding the power consumption of the Lakefield processor. It states that Samsung is planning to increase the TDP from 5 to 7 watts with an update within the next two weeks. Once the update is available, we will have another look at the performance and the surface temperatures.

Processor - Galaxy Book S with Hybrid CPU

Intel Lakefield Hybrid CPU (Source: Intel)
Intel Lakefield Hybrid CPU (Source: Intel)

The Core i5-L16G7 is Intel's first hybrid processor and combines four efficient Atom cores (Tremont cores, 10 nm, up to 2.8 GHz Boost) with a fast Sunny Cove core (10 nm, up to 3.0 GHz), which is also used for the current Ice Lake CPUs. Hyperthreading is not supported, so each core can only execute one thread. Please see our tech section for more details on the architecture. 

The operating system decides how the load is distributed among the cores, but applications have to support the hybrid processor as well in order to utilize the fast core. The results of our initial benchmarks were pretty sobering, because the fast Sunny Cove core was not really utilized. So we were basically dealing with a quad-core Atom processor. You can use the Task manager to assign the faster core for a specific process, but this is not suitable in practice. The Cinebench R15 single-core test was improved from 88 to 111 points (+26%) when we manually selected the faster Sunny Cove core.

Cinebench R20 is a good example for the support of applications (see screenshots below). Version 20.040 cannot utilize the fast core effectively; we can see that 5 threads are executed, but the fifth core does not see much load. This changes with version 20.060, where all cores are fully utilized.

CB R20.040 Multi
CB R20.040 Multi
CB R20.060 Multi

CB R20.040 CB R20.060 Difference
Single-Core 182 Pts 276 Pts +51 %
Multi-Core 479 Pts 609 Pts +22 %

The performance is actually pretty good when the applications supports the hybrid processor, especially considering the low TDP. The Core i3-1000NG4 (Ice Lake-Y, 2 cores/4 threads) from the current MacBook Air is a good comparison. The latter is about 26% faster in the single-core test due to the higher clock, but the Lakefield chip is actually slightly faster in the multi-core test. This is pretty remarkable because the Core i3 in the MacBook Air consumes between 10-11 watts, but the Lakefield i5 is limited to 5 watts.

The support of the applications is currently still a big problem. Our Cinebench R15 Multi loop does not utilize the fifth core, so in this case you only get the performance of the four Atom cores, which falls behind the Core i3-1000NG4. The results are still not bad when you consider the different power consumptions. By the way, the performance is not reduced on battery power.

The browser benchmarks are ideal to compare the Lakefield processor with the ARM Galaxy Book S. The Snapdragon CPU is just beaten in these tests, and the Lakefield chip is clearly beaten by all the other rivals in the majority of benchmarks.

System Performance

The subjective performance impression of the Intel based Galaxy Book S is very good. The device also benefits from the "bad" distribution of the load among the cores. If one core is still available even when you stress the device, the system will still react quickly to inputs and there are no stutters, even during benchmarks. There should not be any problems when you only do daily stuff, and contrary to the ARM based Galaxy Book S, you can install and use all apps without any compatibility issues.

The overall performance level in the synthetic PCMark benchmarks is very low; the comparison devices with 15W processors just have an advantage.

GPU Performance - Throttled Ice-Lake-iGPU

GPU-Z Intel UHD Graphics G7 (Lakefield GT2)
GPU-Z Intel UHD Graphics G7 (Lakefield GT2)

The integrated graphics adapter is basically the fast G7-iGPU we know from the Ice Lake processors. Because of the low TDP, however, the core clock is much lower. The performance in the synthetic is more comparable to the old Intel UHD Graphics 620.

The iGPU is well-suited for everyday situation, and the video decoder has no problems with the playback of high-resolution videos.

Gaming is not great on the Galaxy Book S. The graphics performance drops after a little while (Fire Strike stress test not passed at 82%) and even simple titles hardly reach playable frame rates, which is also a result of the low CPU performance. You should focus on very simple titles from the Windows Store (like card games, for example).

Emissions - Intel version of the Galaxy Book S is also passively cooled

System Noise

Similar to the ARM model, the Intel processor in the Galaxy Book S is passively cooled and we did not notice any other electronic sounds, either.

Temperature

Stress test
Stress test

The surface temperatures are pretty interesting, because they are significantly lower compared to the ARM based Galaxy Book S. We can only measure 40 °C (104 °F) at the bottom at one spot, all the other measurement spots are much cooler. This begs the question why Samsung has reduced the TDP of the processor; the surface temperatures still have some headroom.

We were not able to see the GPU clock during the stress test. The CPU cores are clearly below the 1 GHz mark and you see that Prime95 is not optimized for the hybrid processor.

Energy Management

Power Consumption

Our consumption measurements are pretty interesting, because the Intel version draws more power than the ARM Galaxy Book S in every scenario. There are still advantages compared to rivals with 15W CPUs, bit the difference is often not that big. The power consumption during the stress test quickly drops from 20 to about 13 watts, so the included 25W power adapter is completely sufficient. The idle consumption is increased by 2W when you activate the Outdoor+ mode.

Battery Runtime - Intel version of the Galaxy Book S with reduced stamina

Wi-Fi runtime Outdoor+ mode: 5:15 hours
Wi-Fi runtime Outdoor+ mode: 5:15 hours

The increased power consumption also results in much shorter battery runtimes compared to the ARM model and even the other comparison devices last longer. This means one big advantage of the ARM based Galaxy Book S is gone.

We determine almost 10 hours during our Wi-Fi test at a luminance of 150 cd/m², and about 7 hours with the maximum brightness. If you activate the Outdoor+ mode to use the ~650 cd/m², the runtime drops to little more than 5 hours. The charging time is around 2.5 hours.

In review: Samsung Galaxy Book S

It is not easy to find a verdict for the Samsung's Galaxy Book S with Intel's new hybrid processor. The first rival is obviously the ARM model, which costs about the same. The latter has some advantages, like the extremely long battery runtimes and obviously the integrated LTE module. Both versions are passively cooled. The Intel model on the other hand introduces the much brighter Outdoor+ mode of the screen and is obviously compatible with 64-bit apps, so you can just use the Intel Galaxy Book S like a "normal" Windows laptop.

This leads us to the next comparison, because you can get much more powerful devices for around 1100 Euros (~$1243). These devices will be a bit heavier and are not passively cooled, but even offer longer battery runtimes, comparable display, and just much more performance, which will definitely be noticeable in the next couple of years. This is also the reason why we cannot recommend the galaxy Book S with the Intel processor.

The Galaxy Book S with the ARM processor had some advantages compared to "regular" Windows notebooks. The implementation of the Intel CPU improves compatibility, but some regions do not get the LTE modem, and the battery runtime is also much shorter. All in all, the competition just offers much better overall packages for the money.

The new Lakefield processor is pretty interesting, but it requires the support of applications. In the worst case, you just get the performance of a quad-core Atom processor. The efficiency can be great when it works, but we will have to wait and see if the concept will be successful. We will repeat some tests as soon as Samsung has released the update to increase the power consumption of the processor.

I grew up with computers and modern consumer electronics. I am interested in the technology since I had my first computer, a Commodore C64, and started building my own PCs after that. My focus here at Notebookcheck is the business segment including mobile workstations, but I also like to test new mobile devices. It is always a great experience to review and compare new products. My free time is filled with a lot of sports, in the summer mainly on my bike.
