Lenovo ThinkPad T15p Gen 1 laptop review: Powerful but inefficient

Rustic ThinkPad device. The Lenovo ThinkPad T15p Gen 1 promises a more performant laptop package compared to the regular ThinkPad T15. It keeps this promise, but its performance has drawbacks. And so, in the end, we ask ourselves: For whom is the Lenovo ThinkPad T15p the right laptop?
Benjamin Herzig, 👁 Andreas Osthoff (translated by Stephanie Chamberlain), 🇩🇪 🇮🇹 ...

T ThinkPads with the "p" suffix have been around for a long time. The very first ThinkPad laptop that Notebookcheck was able to review was an IBM ThinkPad T41p in 2005, which was the workstation variant back then. After the Lenovo ThinkPad T61p (2007), the workstations were rebranded to the ThinkPad W series, and today, they go by the name of the ThinkPad P series. However, the T ThinkPads with the small "p" at the end had the chance to celebrate a comeback once again: In 2013, The Lenovo ThinkPad T440p and ThinkPad T540p were launched - here, the focus was on the higher CPU performance compared to the ultrabooks that were new at the time. However, after Intel upgraded its ultrabook CPUs to quad-core chips in 2018, things were over again after the ThinkPad T470p.

Not only did 2020 bring the Corona pandemic but also the return of the "p" suffix in the T series. This time, exclusively with a 15-inch display in the form of today's review unit, the Lenovo ThinkPad T15p Gen 1. It's a variant of the P series, because the equally built ThinkPad P15v is a workstation sibling model. Compared to the latter, the Lenovo ThinkPad T15p packs the GeForce GTX 1050 instead of an Nvidia Quadro GPU. Besides this graphics chip, our test model includes 16 GB of RAM, a 512 GB SSD, a Core i7 with six cores, and an LTE module as well as a 4K UHD display. This corresponds to the top configuration of this series and costs around 2,040 Euros (~$2,473) in Lenovo's Education program. For non-eligible buyers, it costs around 2,260 Euros (~$2,739).

ThinkPad case: Plastic with a magnesium core

Lenovo ThinkPad T15p Gen 1
Lenovo ThinkPad T15p Gen 1

Externally, the Lenovo ThinkPad T15p isn't different from the ThinkPad T15. Both are black, have silver hinges, a keyboard with a number pad, and speakers between the hinges. However, the Lenovo ThinkPad T15p is visibly thicker, and the case is also a bit more angular and boxy.

A look at the spec sheet reveals further differences in materials. In fact, the entire outer chassis of the Lenovo ThinkPad T15p is made of simple PC/ABS plastic instead of fiberglass plastic like on the ThinkPad T15. In this respect, the Lenovo laptop's case is on par with that of the inexpensive ThinkPad L15.

Nevertheless: Workmanship is absolutely spotless. The base unit's stability is also far above reproach; it's even sturdier than the thinner T ThinkPads. The magnesium frame inside the case is responsible for this. The display lid is less stable, and it looks a bit flimsy. In addition, the feel is poor. The classic rubber coating is missing; the LCD lid and palm rest have a smooth coating. The bottom is made of roughened plastic, which feels cheap.

So, it's evident where Lenovo has cut corners. Fortunately, the hinges aren't a part of this: The two drop-down hinges have a good grip on the display and allow an aperture angle of 180 degrees. The monitor can be opened with one hand.

The comparison of dimensions shows that the Lenovo ThinkPad T15p is exactly as long and wide as the ThinkPad T15, but it's almost three millimeters thicker and weighs half a kilogram more.

The Lenovo ThinkPad T15p is also heavier compared to the other rivals, especially compared to the HP EliteBook 855 G7. It's slightly thinner than the Dell Latitude 5511, which is more compact in return and has narrower display bezels.

Connectivity: Lenovo laptop without USB-C Power Delivery

Connectivity is almost identical to that on the ThinkPad T15. There are a few differences: Instead of an additional USB-C port, Lenovo installs a proprietary slim-tip charging port - the single USB-C/Thunderbolt 3 port can't be used to charge the laptop. Furthermore, Lenovo provides the ThinkPad T15p with a full-size SD card reader. All other current T ThinkPads have microSD card readers, so this is a unique feature of the ThinkPad T15p. This is also the case with the ports, since most of them are located on the right side. The fan outlet is on the left in this model.

SD card reader

The performance of the SD card reader was measured with the 64 GB Toshiba Exceria Pro SDXC UHS-II reference memory card. The ThinkPad was faster in reading than in writing. Overall, the Lenovo ThinkPad T15p has to admit defeat to the Dell Latitude 5511 in this discipline.

Communication

The ThinkPad T15p has the full package: Wired (RJ45 Ethernet), local wireless (Wi-Fi 6 in the form of Intel's Wireless AX201), and wireless via mobile networks (WWAN with the Fibocom L850-GL LTE card). This provides maximum flexibility, and the 2x2 AX Wi-Fi card leaves nothing to be desired in terms of performance.

However, WWAN is not available in every model out of the box - such models might be WWAN-ready if the antennas and SIM slot are installed. Some versions, however, might lack this setup.

Security

As usual with proper business laptops, the Lenovo ThinkPad T15p has many security features. These include the Kensington lock, a fingerprint scanner in the palm rest, a smart card reader, and an infrared camera for Windows Hello. There is also the "ThinkShutter" mechanical webcam shutter for privacy.

Accessories

135-watt power adapter with slim-tip connector
135-watt power adapter with slim-tip connector

Only the relatively compact 135-watt power adapter with a slim-tip connector is included in the box. Lenovo no longer offers mechanical docks with the more powerful ThinkPads, but there's still a special solution: The ThinkPad Thunderbolt 3 Workstation Dock Gen 2, which combines the proprietary slim-tip connector with Thunderbolt 3. This is the only dock that Lenovo officially offers for the ThinkPad T15p. Normal USB-C/Thunderbolt 3 docks can't charge the ThinkPad laptop.

Maintenance

Under the bottom panel, which is secured with nine screws and a few clips, we find the large fan with two long heat pipes and the internal battery. Both components are replaceable. One of the two RAM slots is free; the same goes for one of the two M.2 2280 slots. The soldered Wi-Fi card (Intel CNVi) can't be upgraded. In return, the WWAN module (M.2 2242 format) is installed. A very nice feature is the keyboard that can easily be replaced from the top - this is no longer possible on many modern laptops. Lenovo offers a detailed disassembly guide.

Warranty

Like all ThinkPad laptops from the T/X/P series, the Lenovo ThinkPad T15p has a 36-month warranty straight out of the box, in this case with "Pickup & Return" service. On-site repairs cost extra; the same applies to Accidental Damage Protection, Premier Support or a five-year warranty.

The ThinkPad input devices convince in the Lenovo laptop

Keyboard

Lenovo installs a chiclet keyboard with six rows of keys, a two-stage backlight, and a number pad in the ThinkPad T15p. This shifts the entire keyboard slightly to the left. In return, the number pad is very useful in some applications, especially when entering data. Overall, the keyboard has a good layout, with grouped F keys, comfortably sized arrow keys, and dedicated navigation keys. Only the four keys to the left of the Enter key are slightly smaller.

The typing experience on the ThinkPad keyboard is excellent and worthy of the series' good reputation. The smooth keys have an ample travel of 1.8 mm and a generous stroke. The rounded, slightly concave shape of the keys also conforms pleasantly to the fingers. This keyboard is perfectly suited for users who type a lot.

Touchpad and TrackPoint

The combination of the touchpad and the TrackPoint pointing stick, which is installed in almost all ThinkPads, is called UltraNav. The ThinkPad T15p's components come from Synaptics. The touchpad has an adequate area of 10 x 7 cm - not huge but with an appropriate size. It's made of plastic, which is convenient but not really high-quality. You can definitely have expectations for a glass touchpad in a 2,000-Euro (~$2,424) laptop. Apart from that, the hardware of the ClickPad with an integrated click mechanism is good, and software-wise, the touchpad is implemented flawlessly.

The TrackPoint allows you to control the mouse without having to take your hands off the keyboard. This is extremely practical and works perfectly on ThinkPads, because the TrackPoint works very accurately. The three associated buttons also do their job, and the center button can be used for scrolling.

The 4K UHD display convinces with high brightness

Lenovo offers customers a total of three different display options for the ThinkPad T15p Gen 1. All LCDs offered are matte 15.6-inch displays in the 16:9 format:

  • Full HD (1920x1080), 250 cd/m², 45% NTSC color space
  • Full HD (1920x1080), 300 cd/m², 45% NTSC color space, on-cell touch
  • 4K UHD (3840x2160), 600 cd/m², 100% NTSC color space

As the high-end variant, our test device contains the 4K UHD LCD. We were already able to test this display in the ThinkPad P15s; it's currently the brightest panel in a ThinkPad laptop. The average brightness value of 594 cd/m² is just below the targeted 600 mark. Nevertheless, the screen is almost 100 cd/m² brighter than the 4K UHD LCD in the ThinkPad T15.

Out of the box, the display has a good calibration, which we measured with CalMan and the X-Rite i1 Pro 2 colorimeter. Our calibration still led to minor improvements. The very good impression of the panel also extends to the image sharpness, contrast (1859:1), and color space. Around 100% of sRGB and 85% of AdobeRGB are strong rates that also enable the display for image editing.

The ThinkPad laptop scores points with a matte surface and high display brightness in outdoor use. You don't have to be concerned about indirect sunlight either.

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
21.2 ms ... rise ↗ and fall ↘ combined↗ 8.4 ms rise
↘ 12.8 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. » 29 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (24.2 ms).
       Response Time 50% Grey to 80% Grey
41.6 ms ... rise ↗ and fall ↘ combined↗ 19.6 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. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.4 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 9665 (minimum: 5 - maximum: 151500) Hz was measured.

We can't find any complaints regarding the viewing-angle stability of the IPS screen.

Performance: Lenovo ThinkPad T15p with fast components

The Lenovo ThinkPad T15p Gen 1 is sold with Intel Comet Lake-H CPUs. The Core i5-10300Hi5-10400Hi7-10750Hi7-10850H, and i7-10875H are available - but the latter is explicitly not available in EMEA. In terms of graphics, Intel's UHD Graphics 630 is always on board, alongside Nvidia's GeForce GTX 1050 in most models. As for memory, there's up to 64 GB of DDR4-2933 RAM - it's not soldered but upgradeable with two RAM slots instead. Two slots are also available for mass storage, since the ThinkPad T15p can accommodate two M.2 2280 SSDs.

Processor

The Intel Core i7-10750H is a processor from the "Comet Lake-H" series that has six cores (12 threads with Hyper-Threading). The nominal TDP of this chip is 45 watts. The base clock speed is 2.6 GHz (Boost: 5 GHz). For more detailed comparisons with other CPUs, please refer to our CPU comparison list.

In the Lenovo ThinkPad T15p Gen 1, the Intel chip can consume twice the TDP with up to over 91 watts, but this value is only valid for a few seconds. In the long run, the ThinkPad laptop can allow the CPU up to 50 watts, which means clock rates of around 3.4 GHz on all cores.

In terms of CPU performance, the T15p is a very clear upgrade compared to the "normal" ThinkPad T15. Especially in the multi-core test, the difference between Comet Lake-U and Comet Lake-H is indisputable. However: The more compact and lighter HP EliteBook 855 G7 with the AMD Ryzen 5 Pro 4650U achieves almost the same multi-core performance. Only under load on one core does the Intel processor have an advantage, but the higher efficiency of the Ryzen 4000 series is visible.

A limitation in performance was not found on battery power with the ThinkPad T15p.

Graphics card

Nvidia GeForce GTX 1050
Nvidia GeForce GTX 1050

The Nvidia GeForce GTX 1050 is a GPU based on the "Pascal" architecture that is now several years old. Lenovo provides the graphics chip with 768 shader units (maximum clock speed: 1,139 MHz) and 3 GB of GDDR5 memory. Benchmark comparisons are possible with the GPU benchmark list.

GPU performance is clearly better compared to the Nvidia GeForce MX330 of the ThinkPad T15, but with the MX450, the GTX's advantage should soon be history. However, it can still beat current iGPUs easily.

The GPU performance was also fully available on battery power.

Gaming performance

The Nvidia GeForce won't win any prizes for its gaming suitability. The GPU can stably deliver its performance, and we couldn't determine a performance drop in our The Witcher 3 test - however, the chip is fundamentally only good enough for medium details and Full HD resolution in newer games.

Emissions: The Lenovo laptop gets loud and hot

Noise emissions

When the Lenovo ThinkPad is idle, the fan either runs very quietly or not at all - this is also true when browsing the web. However, when the system is put under load, the cooling system reaches a maximum noise level of 42.7 dB(a). That is significantly louder than most other ThinkPads and also very audible.

We didn't notice any coil whine in the Lenovo ThinkPad T15p.

Temperature

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

Under maximum load, the case heats up to 56.6 °C (~134 °F) at the bottom. The palm rest also gets noticeably warm at 38.6 °C (~102 °F). The Lenovo ThinkPad T15p also gets warm in our The Witcher 3 test, but not nearly as excessively: We measured a maximum of 48.9 °C (~120 °F) here.

In the stress test, the CPU of the Lenovo ThinkPad T15p can initially consume up to 88 watts for a few minutes, which puts the processor's temperature at about 100 °C (~212 °F). At the same time, the GPU's clock rates have to be throttled significantly. Over the course of the test, the CPU consumption drops to up to 26 watts, while the graphics chip can simultaneously ramp up its clock rates again. Performance fluctuates for the remainder of the stress test, with the CPU and GPU clock speeds having an inverted trajectory.

The temperature-induced throttling shouldn't affect everyday use; running 3DMark11 after the stress test produces a normal result.

Speakers

The stereo speakers above the keyboard lack bass. Therefore, you should rather use an external solution; the 3.5 mm output intended for this works without issues.

Energy management: ThinkPad laptop pays tribute to Intel Comet Lake and Nvidia Pascal

Energy consumption

In view of the rather inefficient components, the high power consumption is no surprise. The 4K UHD display in particular is likely to drive it up.

The maximum power consumption under load remains below the power adapter's capacity of 135 watts.

Battery life

With 68 Wh, the internal battery currently has the largest capacity in a T-series ThinkPad laptop. However, the 11 watts of additional capacity in comparison to the ThinkPad T15 don't lead to better battery runtimes in the Wi-Fi test due to the higher consumption - 7:41 hours is not a terrible rate, but it is below average. Battery life should be better with a Full HD display, but you have to put up with the poorer display quality in return.

Verdict: The ThinkPad T15p is a good laptop - but for whom?

In review: Lenovo ThinkPad T15p Gen 1, provided by

The Lenovo ThinkPad T15p is neither the thinnest nor the most powerful ThinkPad laptop in its class. It may be lighter and thinner than the bulky ThinkPad P15, but the Lenovo ThinkPad X1 Extreme Gen 3 is even more compact. And it can't compete with these models when it comes to graphics performance in particular.

However, the ThinkPad T15p also has its strengths. Compared with the regular Lenovo ThinkPad T15, it represents a significant performance upgrade. It also has a full-size SD card reader. The keyboard, touchpad, and TrackPoint are beyond reproach, and the selection of connectivity functions and security features is broad - this includes the availability of LTE out of the box. Lenovo didn't skimp on the display either: The 4K UHD display performs strongly in every respect. The ThinkPad T15p is also upgradeable, and the model with the "p" suffix offers more expansion options compared to the T15. We draw a mixed verdict when it comes to the case: Although it's sturdy, it feels relatively cheap compared to the other ThinkPad laptops.

Battery life is rather weak. This is where the inefficient components and the 4K display take their toll. Speaking of tolls: The ThinkPad T15p "dazzles" with a combination of high temperatures and high fan volume under load. The cooling system seems to be rather underpowered. We find it odd that Lenovo has completely omitted the possibility to charge the laptop via USB-C. We don't see a reason why this function should be left out.

A tough case: Viewed on its own, the Lenovo ThinkPad T15p Gen 1 is a good, powerful work laptop for the desk at home. However, the in-house competition makes life difficult for the ThinkPad laptop.

We can't advise against the ThinkPad T15p, but we also have a hard time making a recommendation. A clear purpose is missing, and the in-house competition is too strong. The T15p isn't cheap either, and if you're willing to pay over 2,000 Euros (~$2,424), you might as well buy the ThinkPad X1 Extreme Gen 3. It lacks many of the ThinkPad T15p's weak points. Apart from RJ45 Ethernet and the numeric keypad, the T15p has no real advantages over it.

Price and availability

The Lenovo ThinkPad T15p Gen 1 is available on Lenovo's online store in several configurations; at the time of writing our review (mid-February), all models of the T15p Gen 1 are currently discounted. The base model starts at around $1,200 (Intel Core i5-10300H, 8 GB of RAM, 256 GB of PCIe SSD storage, Full HD display at 250 nits, integrated graphics only). A version with our same CPU, the Intel Core i7-10750H, 16 GB of RAM, 512 GB of storage, the Nvidia GeForce GTX 1050, and the same display as the base model currently costs about $1,600. The only model that comes with a 4K display also upgrades the CPU to the i7-10850H and the storage space to 1 TB for a price of around $2,100.
