Lenovo ThinkPad P15s Gen 1 Laptop Review: Ultraportable workstation with a very bright 4K screen

Well-known laptop with a new screen. We are already familiar with the Lenovo ThinkPad P15s Gen 1 even though this is the first time we have it in our hands. This may sound like a contradiction, however, we are familiar with all the aspects of the ThinkPad P15s Gen 1 except for one: The factory-calibrated UHD display that is supposed to be brighter than all other ThinkPad screens.
Benjamin Herzig, 👁 Andreas Osthoff (translated by Stanislav Kokhanyuk), 🇩🇪 🇳🇱 ...

15.6-inch ThinkPads are not as well liked as their smaller 14-inch counterparts. However, things are different in the workstation segment. Recently, we reviewed the Lenovo ThinkPad P14s, and now we are taking a look at its bigger brother ThinkPad P15s Gen 1.

Just like the smaller P14s, the Lenovo ThinkPad P15s uses the same design as other laptops in the current ThinkPad T series. The ThinkPad T15 is the latest sibling model. Because there were no changes in terms of design, connectivity and input devices, we forewent including the information contained in the pertinent sections in this review. Readers can find all relevant information in our review of the ThinkPad T590

In addition to the ThinkPad T15 and its direct predecessor Lenovo ThinkPad P53s, we compare the ThinkPad P15s to the ZBook Firefly 15 G7, which is a direct competitor from HP.

The P15s Gen 1 and its sibling model ThinkPad T15 Gen 1 come with different 15.6-inch 16:9 screens. The cheaper screen options are identical (a 300-nit touchscreen and a 250-nit display without touch support). However, the Lenovo ThinkPad P15s comes with a 4K panel with an advertised brightness of 600 cd/m², whereas the ThinkPad T15 comes with a UHD panel with a maximum brightness of only 500 cd/m². All display options offer a matte surface and are based on IPS technology.

According to our measurements, the UHD panel of the ThinkPad P15s has an average brightness of 608 cd/m². It is more than 100 cd/m² brighter than the 4K panel in the ThinkPad T15. The 2160p screen of the ThinkPad P15s is also 200 cd/m² brighter than that of the ZBook Firefly 15 G7. This panel, which is known as MNF601EA1-1, is, in all likelihood, the brightest panel in a ThinkPad ever and is also used in other current ThinkPads in the P series and in the ThinkPad X1 Extreme Gen 3.

The screen of the Lenovo ThinkPad P15s Gen 1 has been calibrated at the factory. This is likely only the case for the UHD panel, which is quite colour-accurate straight out of the box. However, this does not mean that it is perfect: Dark tones appear somewhat greyish, because the black value is quite high. The contrast ratio (1600:1) is very good, though, thanks to a high screen brightness. The panel also supports HDR, which means that the ThinkPad P15s Gen 1 can properly display HDR content.

Thanks to a wide colour gamut, the Lenovo notebook can be used for colour-critical work such as video and image editing. The P15s Gen 1 covers 99.4 % of the sRGB colour space and 85.6 % of AdobeRGB. The wide colour gamut is the main advantage when compared to the cheaper Full HD options. The P15s Gen 1 comes with several pre-configured colour profiles. This is not the case with other ThinkPads.

Thanks to a matte surface and high maximum brightness, the display of the P15s Gen 1 is legible in indirect sunlight. In the shade or under an overcast sky, the screen is easy to read.

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
24.8 ms ... rise ↗ and fall ↘ combined↗ 12.4 ms rise
↘ 12.4 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 43 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.1 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 22 ms fall
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 636 (maximum) ms. » 55 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.2 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9706 (minimum: 5 - maximum: 151500) Hz was measured.

The Lenovo laptop offers very good viewing angles, because it features an IPS panel.

Performance: Old components hold the Lenovo laptop back

According to the specifications sheet, the P15s Gen 1 offers almost the full array of Intel’s Comet Lake CPUs, from the quad-core i5-10210U to the hexa-core i7-10810U. However, the hexa-core models are nearly impossible to get. Moreover, there are no models with AMD chips, which is why you can only get a ThinkPad P15s Gen 1 with a quad-core CPU. All P15s Gen 1 models come with an Nvidia Quadro P520, which works in tandem with the Intel UHD Graphics 620 through Nvidia’s Optimus GPU-switching technology.

When it comes to RAM, there are two options: 8 or 16 GB of soldered-in DDR4 2666 RAM. There is also a SO-DIMM slot, which supports sticks with a maximum capacity of 32 GB. This means that the maximum amount of RAM for the ThinkPad P15s Gen 1 is 48 GB. There is an M.2-2280 slot for long-term storage devices.

Processor

The Intel Core i7-10510U is a quad-core Comet Lake-based CPU. The four cores can clock up to 4.8 GHz. However, the base clock is 1.8 GHz. To find out how the Intel chip stacks up against other processors, go to our CPU comparison page

The maximum power draw of the ThinkPad P15s Gen 1’s processor, which has a nominal TDP of 15 watts, amounts to roughly 50 watts. However, the CPU can only draw this much power over a short period of time. When the CPU is not boosting, it is limited to 25 watts, and once the CPU starts to overheat, the power consumption drops to around 17 watts. 

This actually explains fluctuations that we saw in our Cinebench loop. Interestingly enough, the identically built ThinkPad T15 with the same CPU performs slightly better in this test. All in all, the difference is marginal and we wish that there were P15s models with AMD's Ryzen CPUs.

The CPU does not throttle when running on battery power.

System Performance

Earlier generations of ultraportable workstations offered subpar levels of system performance when they were paired with a 4K display. This was the case with models that featured dual-core processors. Fortunately, this is not the case with the ThinkPad P15s. Despite its UHD screen, it feels very responsive and performs very well in the PCMark benchmarks.

Storage Devices

The ThinkPad P53s was the last ultraportable workstation with a 2.5-inch drive bay. The ThinkPad P15s comes with a single M.2-2280 SSD. The NVMe SSD has a storage capacity of 1 TB, which should be more than enough for most users. Our storage benchmarks reveal that the Samsung PM981a offers superb data transfer rates.

Graphics Card

The Nvidia Quadro P520 is a Pascal-based GPU. This chip is outdated. Quite recently, it was replaced by the Nvidia Quadro T500. The P520 is the slowest mobile Quadro GPU that is still available on the market.

This is why it is not surprising that the ThinkPad P15s performs only half as well as the average workstation. In the productivity benchmark SPECviewperf 13, the P15s performs even worse than that. When running on battery power, the performance of the Lenovo workstation is 55 % lower.

Gaming Performance

The laptop is too anaemic for 4K gaming. However, even at lower resolutions, the P15s Gen 1 struggles to handle AAA titles. The Quadro GPU is simply not meant for gaming.

Emissions: ThinkPad P15s gets very hot

System Noise

In idle operation, the fan stands still. When the fan kicks in, it seems to always operate at a set speed. With the fan on, we measured a sound pressure level of 35.5 dB(a), which is not very loud, but still audible. 

Unfortunately, the ThinkPad P15s suffers from coil whine. Susceptible individuals may find it annoying, especially since it is audible even at a normal distance from the laptop.

Temperature

Stress test (Prime95 + FurMark)
Stress test (Prime95 + FurMark)

The surface temperatures of the Lenovo ThinkPad T15 peaked at about 60 °C (140°F). The Lenovo ThinkPad P15s Gen 1 gets even hotter with the surface temperatures on the underside reaching almost 65 °C (149°F).

The stress reveals that the cooling system of the ThinkPad P15s is not powerful enough to keep both the CPU and the GPU sufficiently cool at the same time. The GPU can maintain its clocks for more than an hour, but the CPU can maintain the TDP of 25 watts only for a few minutes. Eventually, the GPU clocks settle at about 7 watts.

In the 3DMark 11 benchmark, which we conducted right after the stress test, the ThinkPad P15s scored only roughly 4000 points in the physics section instead of roughly 10000 points. This is a 60-% drop in peformance. This means that users of the Lenovo laptop might experience thermal throttling even in day-to-day use.

Energy Management: UHD screen drives up power consumption

Energy Consumption

The Lenovo laptop draws more power than the HP ZBook Firefly 15 G7. The ThinkPad P15s has a comparable power draw only when idle. In all other cases, the ZBook is about 30 % more energy-efficient. The main reason for this is the UHD panel in the ThinkPad P15s. The ZBook also comes with a 4K screen, but it is significantly less bright.

The peak power draw is higher than the rated output of the AC adapter. However, because the average power consumption is well below 65 watts this should not be a major problem.

Battery Life

When compared to the smaller ThinkPad P14s, the battery capacity of the P15s is higher (57 watts) and is comparable to that of the HP ZBook Firefly 15 G7. Nevertheless, the HP notebook achieves a 10-% longer battery runtime in our Wi-Fi test, because it has a lower power draw. With the screen brightness maxed out, the Lenovo laptop achieves a very poor battery runtime. However, it has a much brighter screen.

We know the Lenovo ThinkPad P15s Gen 1 well, because we have already reviewed it more than once. However, it went by different names. Having mentioned that, the ThinkPad T590ThinkPad P53s and the ThinkPad T15 Gen 1 have the same design and offer very similar hardware.

This is why our assessment of most aspects remains unchanged: Thanks to its robust housing and comfortable input devices, the ThinkPad P15s is a good professional notebook. However, we would like to see an AMD option, because the Intel CPUs and Nvidia GPUs that the P15s offers are outdated. Moreover, the cooling system of the ThinkPad P15s is not powerful enough to keep it from overheating. Moreover, we also have to mention the presence of coil whine.

What separates the ThinkPad P15s from the aforementioned ThinkPad laptops is the 4K screen. There were and are other models with UHD displays, but none can hold a candle to the level of brightness that the 2160p panel in the ThinkPad P15s can achieve. This also applies to the ZBook Firefly 15 G7, its direct competitor from HP. 

We can only recommend the Lenovo ThinkPad P15s Gen 1 to those who want the following laptop: A low-end workstation with a CAD-capable GPU, which offers the lowest level of performance acceptable in this segment.

There is only a single feature that distinguishes the ThinkPad P15s from the ThinkPad T15 and the ZBook Firefly 15. However, we expect that Lenovo will soon release the ThinkPad P15s Gen 2 with Tiger Lake-based CPUs and the Nvidia Quadro T500. This is why it might be worth it to wait.

Price and Availability

The configuration featured in our review with a 1 TB SSD, 32 GB of RAM and a 4K screen currently retails on Amazon for 2157 Euros (~$2636).

I was an ardent reader of Notebookcheck’s laptop reviews even back in school. After writing reviews as a hobby, I then joined Notebookcheck in 2016 and have worked on device reviews and news articles ever since then. My personal interest lies more with laptops than smartphones, with business laptops being the most interesting category for me. Technology should make our lives and work easier and good laptops are an essential tool for that to happen. This is why laptop reviews are not just my work but are also my passion.
