Lenovo ThinkPad X12 laptop review: Detachable with Intel Core i3 is quite slow

Weak version. We have already reviewed the Lenovo ThinkPad X12 Detachable with i7, and now we will update our review of the i3 version. There is one thing to say in advance: we cannot recommend the CPU downgrade to the i3.

12 inches - this size has largely disappeared from the laptop market. There used to be a selection of 12-inch laptops every year, especially business laptops, but nowadays the smallest notebooks for business customers have 13-inch screens. Niches, where smaller screens continue to exist, are tablets and detachable models - those like the Lenovo ThinkPad X12 Detachable.

The configuration of today's test device is similarly niche - a dual-core processor in a laptop in 2022, that does not happen that often anymore, either. We have already tested the ThinkPad X12 with a quad-core chip, so our review today will skip the sections about the design, the equipment, and the input devices. Information about these topics can be found in the already mentioned detailed review of the ThinkPad X12 with i7 CPU.

Display: ThinkPad tablet in 3:2 format

Lenovo only uses one display for the ThinkPad X12 Detachable: a 12.3-inch FHD+ panel (1,920 x 1,280) in a 3:2 format. The screen is glossy with an anti-reflective coating, which means reduced reflections. According to Lenovo, the ThinkPad X12 is supposed to achieve a brightness value of 400 cd/m². Unfortunately, the panel installed here achieves a considerably lower value of 324 cd/m². We were probably just unlucky with the series deviations because the already tested Lenovo X12 with i7 achieved much better rates - but the difference is so big that one could almost suspect a defect. In return, the panel tested here scores better in terms of response times.

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
22 ms ... rise ↗ and fall ↘ combined↗ 10.8 ms rise
↘ 11.8 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 0.1 (minimum) to 240 (maximum) ms. » 42 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
45.1 ms ... rise ↗ and fall ↘ combined↗ 20.1 ms rise
↘ 24.5 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.9 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18080 (minimum: 5 - maximum: 3846000) Hz was measured.

The screen's lack of cd/m² would definitely be helpful in outdoor use, even though you can still use the ThinkPad X12 Detachable in the shade. The surface is reflective, but the reflections are reduced.

Performance: ThinkPad X12 with i3 only for simple tasks

Lenovo provides the Intel CPUs from the "Tiger-Lake-UP4" series with 8 or 16 GB LPDDR4X-4266 memory and an upgradeable M.2-2242 SSD. On the other hand, the memory is soldered. There is also no dGPU in this compact tablet. The ThinkPad X12 relies fully on the integrated Intel iGPU.

Test conditions

For prolonged load, a power limit of only 10.5 watts applies in the Windows performance mode "Best Performance", which was active during our performance tests. For short-term load, the CPU of the Lenovo ThinkPad X12 Detachable can consume up to 22 watts.

Processor

An Intel Core i3-1110G4 is a Tiger Lake processor from the UP4 series. This means that this dual-core processor has a typical consumption (TDP) of 15 watts. The two cores (four threads thanks to Hyperthreading) clock with 2.5 to 3.9 GHz. Our CPU benchmark list will help to compare the chip with other CPUs.

CPUs with only two cores are rare these days. Our benchmarks also clearly show why: the performance clearly lags behind the other detachable with four cores. The ThinkPad X12 achieves much higher performance with twice as many cores. The dual-core variant on the other hand is only suitable for the lightest tasks in everyday office and internet use.

The CPU performance is on the same level in battery mode as with the power supply connected.

Graphics card

Actually the Intel UHD Graphics 620 has been superseded by Intel Xe, but it has survived in inexpensive i3 CPUs like in the ThinkPad X12. Its performance is on a low level, it is only suitable for the simplest games from the Microsoft Store, older titles in the lowest resolution level, or 4K video playback.

Emissions & energy: ThinkPad laptop with low heat development

Noise emissions

Compared to the ThinkPad X12 Detachable with i7 CPU the fan behavior has changed slightly. The average load volume is lower, but the fan gets a bit louder under maximum load. Presumably, Lenovo adjusted the behavior via BIOS update. Overall, the Lenovo ThinkPad X12 Detachable remains mostly silent during use. We did not hear any noise from the X12.

Temperature

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

In view of the weak processor, it is by no means surprising that Lenovo's ThinkPad X12 Detachable stays extremely cool and undercuts its i7 counterpart by several degrees. 39.8 degrees Celsius at the back are the absolute maximum in the stress test. The Microsoft Surface Pro 8 with its much faster processor gets noticeably warmer with a maximum of 47.2 degrees Celsius

After one hour of stress testing, the two cores still clock at 1 GHz and the processor consumes around 10 watts. However, this TDP throttling will not have an impact on everyday use.

Speaker

The speakers of the Lenovo ThinkPad X12 Detachable lack bass and also volume. The Microsoft Surface Pro 8 proves that a tablet does not have to deliver bad sound. Its speakers get louder, deliver more bass, and are simply more balanced overall.

Energy consumption

The energy consumption at idle is lower than that of the ThinkPad X12 with i7 CPU and also with the Microsoft Surface Pro 8. However, the Dell Latitude 7320 is even more frugal in this respect.

The maximum energy consumption is 55 watts and thus clearly below the power supply capacity of 65 watts. However, an even narrower 45-watt power supply would not be sufficient under maximum load.

Battery life

The battery runtime has not improved despite the lower idle consumption. On the contrary: the Lenovo ThinkPad X12 Detachable with i7 is just ahead, although the capacity of the 42-Wh battery has not changed. Both variants of the ThinkPad X12 remain clearly behind the Dell Latitude 7320 with seven to eight hours, which comes to 10 hours in the WiFi test (150 cd/m²).

Verdict: Lenovo ThinkPad X12 Detachable with i3 makes little sense

In review: Lenovo ThinkPad X12 Detachable, test device provided by
In review: Lenovo ThinkPad X12 Detachable, test device provided by

Performance certainly does not play the decisive role in an ultra-mobile tablet, but things look a bit different when it is also supposed to do the job of a full-blown laptop. The Lenovo ThinkPad X12 Detachable is undoubtedly a laptop replacement. After all, it still costs over 1,000 Euros even with an i3 CPU.

The performance of the tested i3 variant is simply too weak for this price. It can certainly be argued that it is sufficient for pure office use. But an i5 model with four cores is not considerably more expensive and is much more future-proof. Apart from the minimally lower price, the i3 variant hardly offers any other real advantages, apart from the lower heat development.

With i3 too slow for the price: The Lenovo ThinkPad X12 Detachable should include at least a Core i5.

If it has to be the Lenovo ThinkPad X12 Detachable, then chose configuration with i5 or i7. The ThinkPad does have its advantages, such as the basically upgradeable SSD and the very good keyboard. If performance is more important, then the Microsoft Surface Pro 8 could be a superior option. For better battery life, the Dell Latitude 7320 Detachable might also be worth a look.
