Lenovo ThinkPad P51s (Core i7, 4K) Workstation Review

Sascha Mölck, 👁 Andreas Osthoff, Stefanie Voigt (translated by Liala Stieglitz), 06/10/2017

Enduring. Lenovo's mobile ThinkPad P51s workstation is slimmer and more compact than its predecessor. The device can now also offer a modern Thunderbolt 3 interface. Thanks to a high-capacity external battery, the laptop achieves an outstanding battery life.

We are looking at the ThinkPad P51s, which is the successor of the ThinkPad P50s. Both devices are mobile, 15.6-inch entry-level workstations. The devices are not identical. While the P50s is based on the ThinkPad W550, the P51s is an identically built sibling of the ThinkPad T570. We have already tested the latter several times, among them a model with a 4K screen and GeForce 940MX graphics core. Our P51s review model is based on this version. Devices like HP's ZBook Studio G3 and Dell's Precision 5520 UHD are rivals of the laptop.

Since the ThinkPad P51s and ThinkPad T570 are identical, we will not go in-depth about the casing, connectivity, input devices or speakers. The corresponding information can be found in the reviews of the ThinkPad T570-20HAS01E00 (Core i7, 4K) and ThinkPad T570-20H90002GE (Core i5, Full HD).

Display

The ThinkPad P51s is furnished with the same matte 4K panel (3840x2160 pixels) as the ThinkPad T570 that we have previously tested. It is a viewing-angle stable IPS screen that offers a good contrast (991:1) and a very decent brightness value (289.9 cd/m²). Nevertheless, better rates could be expected from a device in this price range. A contrast beyond 1000:1 (and brightness rate much higher than 300 cd/m²) would not be too much to ask.

Unfortunately, the screen exhibits PWM-flickering at a frequency of 980.4 Hz at brightness levels of 90% and lower. The high frequency should not cause headaches and/or eye problems in sensitive users, though.

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 detected 980.4 Hz ≤ 90 % brightness setting

The display backlight flickers at 980.4 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 980.4 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8781 (minimum: 43 - maximum: 142900) Hz was measured.

The screen can boast with a relatively decent color reproduction in delivery state. The DeltaE 2000 color shift is 3.6. A rate less than three would be desirable. The screen does not have a bluish tint, but it displays a very light greenish tint. It can be eliminated via calibration. Calibrating also reduces the color shift (to 1.7) and offers a clearly more balanced grayscale reproduction.

The color profile that we provide can be used to improve the screen's color reproduction according to our calibration. However, it should be checked that the same screen model (manufacturer + model number) is installed as in our review sample. Otherwise, the color reproduction could deteriorate even more. Screens from different manufacturers are often used within a laptop model lineup.

The screen cannot display the AdobeRGB and sRGB color spaces completely. The coverage rates are 91% (sRGB) and 59% (AdobeRGB). Users who rely on high color-space coverage should look at the 4K model of the ThinkPad P51. Lenovo promises 100% NTSC color-space coverage. The review of the device that will be published shortly will show whether this promise is kept.

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↗ 13.6 ms rise
↘ 11.2 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. » 38 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms rise
↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 38 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41 ms).

Processor

One of the strongest ULV CPUs (TDP: 15 watts) that Intel presently has to offer is inside the ThinkPad - the Core i7-7600U (Kaby Lake) dual-core processor. The CPU looks good in all application fields. Users who need higher multithread computing power will opt for a ThinkPad P51 model. These models are available with quad-core processors. The 7600U processor in the P51s clocks at a base speed of 2.9 GHz, which can be boosted up to 3.9 GHz (both cores) via Turbo.

The processor performed our CPU tests at 3.5 to 3.9 GHz (multithread) and 3.7 to 3.9 GHz (single-thread) - but this is only true for AC mode. The clock rates dropped to 1.8 to 2.4 (single- and multithread) in battery mode. The reason for this: While the TDP can be extended up to 25 watts in AC mode, Lenovo limits it to 8 to 9 watts in battery mode. Consequently, the CPU cannot operate at full speed. Changing the energy settings in the BIOS does not lead to a different behavior. Our review sample is furnished with the newest BIOS version (1.21 from April 2017).

HWMonitor in a Cinebench R15 multithread test run (battery mode)
HWMonitor in a Cinebench R15 multithread test run (AC mode)
HWMonitor in a Cinebench R15 multithread test run (AC mode)

We checked whether Turbo is utilized permanently in AC mode by looping the Cinebench R15 multithread test for approximately 30 minutes. The result drops a few percentage points in the first to the sixth run and then remains stable. Thus, the performance is reduced slightly because Lenovo limits the CPU temperature to 75 °C.

System Performance

A fast SSD and strong processor ensure a fast system. We did not encounter any problems. The PCMark benchmark scores are very good. The laptop's total performance can be increased a bit. A second working memory bar would have to be installed into the ThinkPad for this.

Storage Device

An NVMe SSD by Samsung is installed as the system drive. It is an M.2 2280 model with a total capacity of 1 TB. However, the SSD is not inserted into an M.2 slot but is connected to a SATA Express slot via an adapter. The latter is the successor of SATA III. SATA Express combines SATA and PCI Express 3.0, i.e. not only NVMe SSDs can be connected to this interface but also conventional 2.5-inch SATA hard drives. Data is transmitted via PCI Express here. Up to four PCIe 3.0 lanes can be used. Two lanes are utilized in the ThinkPad. Consequently, the SSD's transfer rates remain behind its potential. However, the rates are still very good. Installing Samsung's NVMe driver does not have an impact on the transfer rates.

Graphics Card

The ThinkPad is furnished with Nvidia's Quadro M520 GPU. It is, so to say, the professional variant of the known GeForce 940MX graphics unit installed in many laptops. The latter is also found in the 4K model of the ThinkPad T570, for example. Differences between the Quadro and GeForce are primarily found in software. Nvidia publishes certified drivers for Quadro GPU that are optimized for professional applications (e.g. CAD, visualizations). Consequently, the Quadro GPUs do a much better job in these applications than their consumer counterparts.

The Quadro M520 core supports DirectX 12 and OpenGL 4.5. It clocks at a base speed of 965 MHz. Up to 1176 MHz is possible via Turbo. The GPU can fall back on a fast 2048 MB GDRR5 graphics memory. The memory is the biggest reason that the M520 scores much better in our GPU tests than the former Quadro M500 model. Both GPUs are based on Nvidia's Maxwell architecture.

The ThinkPad also provides a graphics-switching solution (Optimus). Intel's HD Graphics 620 graphics core is enabled.

Gaming Performance

The ThinkPad is not a gaming laptop. Nevertheless, the installed hardware allows playing many games. High resolutions - and even the screen's maximum resolution - are only rarely up to not at all possible. Most games achieve smooth frame rates in the HD resolution (1366x768 pixels) and low to medium quality settings. This is primarily true for games that do not have very high hardware requirements. Performance-driven games, such as Mass Effect Andromeda, require reducing the resolution and/or quality settings.

Emissions

System Noise

The ThinkPad does not produce an excessive amount of noise. The fan is often inactive during idle mode and silence then prevails. The fan speeds up during load. We measured a noise level of 39.4 dB in the stress test. A quiet electronic sizzling can be heard from inside the laptop when holding an ear to it. It is not audible at a normal sitting distance. Nevertheless, this should not occur in a device from this price range.

Temperature

The ThinkPad in the stress test
The ThinkPad in the stress test

Lenovo's laptop performed our stress test (Prime95 and Furmark run for at least one hour) differently in AC and battery modes. The GPU clocks at full speed (1176 MHz) in battery mode. The CPU throttles to 400 MHz. When running the stress test in AC mode, the CPU and GPU clock at full speed for a few seconds. The CPU then throttles to speeds clearly below 1.5 GHz while the graphics unit still clocks at full speed (1176 MHz). The graphics core's speeds drops gradually and consistently in the course of the test. The CPU's speed climbs proportionally to that. The clock rates settle to about 915 MHz (GPU) and 2 to 2.5 GHz (CPU). The aforementioned CPU temperature limit of 75 °C is also noticed in the stress test.

We reran the 3D Mark 2011 benchmark directly after the stress test. The score is on par with the outcome that we recorded after a cold start run of the benchmark. Thus, the user will not have to deal with performance throttling in routine use.

The ThinkPad heated up quite palpably during our stress test - too palpably for a ULV laptop. However, this should not be disconcerting. Our stress test is an extreme scenario that will not occur in daily use. Thus, the temperature increase will usually be much lower in routine use.

Energy Management

Power Consumption

We measured a maximum idle power consumption of 13.5 watts - a very high rate for a ULV laptop. The 4K screen is responsible for this. At the beginning of the stress test, the rate climbed to 73.1 watts. The 65-watt power supply is overloaded with this. However, the rate drops since the CPU and GPU throttle. The power consumption was 51 watts at the end of the stress test.

Battery Runtime

The ThinkPad achieves a runtime of 11:52 hours in our practical Wi-Fi test. We simulate the load needed for opening websites via a script here. The "Balanced" profile is enabled, the energy-saving features are disabled, and the screen's brightness is set to approximately 150 cd/m². The P51s finished the video test after 11:40 hours. We loop the short video Big Buck Bunny (H.264 encoding, 1920x1080 pixels) for this. The "Energy Saving" profile is enabled, the wireless modules and energy-saving features are disabled, and the screen's brightness is dimmed to 150 cd/m².

We performed an additional load test. We looped the SpecviewPerf 12 benchmark using the "High Performance" profile. The ThinkPad achieved a runtime of almost 3 hours here.

Like the ThinkPad T570, the ThinkPad P51s has an internal battery (32 Wh) and an external battery. Our review sample comes with the highest capacity battery (72 Wh) that Lenovo offers. Consequently, the laptop delivers outstanding battery runtimes. The 72 Wh battery protrudes visibly toward the bottom. Thus, the ThinkPad does not lie evenly on a surface but is tilted toward the user.

Lenovo provides a compact, 15.6-inch, mobile workstation with its ThinkPad P51s. However, buyers should be aware that the workstation's performance is limited due to the ULV processor. A workstation with a quad-core processor will be needed for much higher performance - for example, the ThinkPad P51.

The ThinkPad is the identically built sibling of the ThinkPad T570. Thus, the P51s features the same solid casing, the good input devices, and the diverse connectivity of the T570. The infrared camera is also installed.

Unfortunately, the P51s also inherits the shortcomings of the T570. For example, the CPU throttles in battery mode. We measured clock rates of approximately 1.8 to 2.4 GHz. This throttling results in a deduction. Furthermore, the laptop heated up too strongly in our stress test. We recorded a temperature of 60.8 °C on one measuring point - too high for a ULV laptop. Noise development looks better; the ThinkPad is on a normal level here.

The outstanding battery life is a highlight of the laptop.

In total, the P51s has a battery capacity of 104 Wh (internal: 32 Wh, external: 72 Wh). That is enough to keep even a 4K laptop running for a long time. A fast NVMe SSD ensures a quick system. The laptop could also be equipped with a 2.5-inch hard drive instead of an M.2 NVMe SSD. An LTE modem could also be retrofitted; our review sample has an empty slot and the corresponding antennas.

The matte 4K screen in the P51s is known from the ThinkPad T570. Both laptops are furnished with the same panel. The IPS screen pleases with stable viewing angles and a good contrast. The brightness is satisfactory although it could be higher. Unfortunately, the screen exhibits PWM-flickering at brightness levels of 90% and lower.
