Lenovo ThinkPad L13 Yoga G4 Intel convertible review: Shorter battery life than AMD
The ThinkPad L13 Yoga Gen 4 is available in both Intel and AMD versions to attract users on both sides of the fence. This review page will focus on the Intel version as we recently reviewed the AMD version back in August. All our comments on the physical features of the AMD version apply here since the two versions are visually identical.
Our Intel review unit is a higher-end configuration with the 13th gen Raptor Lake-U Core i7-1355U CPU, 16 GB RAM, and 1200p IPS touchscreen for approximately $1400 to 600 USD retail. Other configurations range from the Core i3-1315U up to the Core i7-1365U with vPro, but all options are otherwise limited to integrated graphics and a 1200p display.
Alternatives to the ThinkPad L13 Yoga G4 include other business-centric convertibles like the MSI Summit E13 Flip Evo, HP Elite Dragonfly Folio 13.5, or the Dell Latitude 7330 2-in-1.

Case
Much like on the recent ThinkPad E14 G5, the quickest way to identify the Intel version from AMD is to look for the Thunderbolt logo along the left edge as the AMD options lack the feature. Note that while the model ships with two USB-C ports, only the left port is compatible with Thunderbolt devices like eGPUs.
Communication
An Intel AX201 comes standard for Wi-Fi 6 and Bluetooth 5.1 support while the Intel AX211 with Wi-Fi 6E is optional.

Webcam
IR is optional while the privacy shutter comes standard. Lower-end SKUs only come with a 720p webcam whereas higher-end SKUs offer 1080p.
Maintenance
There are no major internal differences in terms of upgradeability between the AMD and Intel versions as shown by the comparison images below.
Accessories And Warranty
The retail box includes an AC adapter and active stylus pen. The pen is housed within the laptop itself for both convenience and charging.
Display
Our Intel unit comes with a different 1200p IPS panel as found on our AMD unit (NV133WUM-N61 vs. B133UAN01.2). This particular panel appears to be slightly dimmer by about 50 to 60 nits while offering faster black-white and gray-gray response times to minimize ghosting. Color and image quality are otherwise very similar between the two models.
It's unfortunate that Lenovo offers no 90 Hz or 120 Hz refresh rate options considering the high $1500+ asking price.

Calibrating the panel ourselves with an X-Rite colorimeter would improve average grayscale and color DeltaE values from 3.9 and 2.6 to just 0.4 and 0.51, respectively. Our calibrated ICM profile is available above to download for free.

Performance
Testing Conditions
We set Windows to Performance mode prior to running the benchmarks below. There are no additional power profiles beyond the standard Windows ones (Power Saver, Balanced, and Performance).
Processor
CPU performance is slightly slower than most other laptops with the same Core i7-1355U due to throttling. When running CineBench R15 xT in a loop, for example, the initial score of 1274 points would fall by as much as 35 percent over time as shown by the graph below. Multi-thread performance is thus only a bit better than the competing Ryzen 5 7530U configuration after accounting for the higher throttling on the Intel version.
The main advantage for Intel continues to be in single-thread performance where our Core i7 has a 20 to 25 percent lead over the Ryzen 5 7530U.

System Performance
PCMark scores are higher in the GPU-heavy Digital Content Creation subtest whereas the CPU-heavy Productivity test favors the AMD version. This suggests that our Intel version offers better integrated graphics performance but slower CPU multi-thread performance than the AMD version.

Frame rate stability when gaming is unfortunately unsteady. When idling on Witcher 3 on low settings, for example, frame rates would fluctuate between 70 and 85 FPS as shown by the graph below to suggest fluctuating clock rates over time. The ThinkPad L13 is thankfully not a gaming laptop and so this specific disadvantage shouldn't be a deal breaker to the target audience. Streaming applications still run smoothly on the machine.

Emissions
System Noise
Fan noise can be louder on the Intel version than on the AMD version when running demanding loads like 3DMark which may be attributed to the faster graphics performance and overall power consumption of the Intel version. Otherwise, fan noise would typically hover in the low 30 dB(A) range when web browsing or streaming to be easily ignorable in most office or conference settings.

Temperature
Hot spots can reach 40 C on the right side of the keyboard similar to what we recorded on the AMD configuration. Thus, the Intel unit does not run significantly cooler or warmer despite their performance differences.
(+) The maximum temperature on the upper side is 38.4 °C / 101 F, compared to the average of 35.3 °C / 96 F, ranging from 19.6 to 55.7 °C for the class Convertible.
(-) The bottom heats up to a maximum of 46 °C / 115 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 27.2 °C / 81 F, compared to the device average of 30.2 °C / 86 F.

Stress Test
When initiating Prime95 stress, the CPU would boost to 3 GHz, 89 C, and 35 W for only the first few seconds before steadily falling and stabilizing at 2.2 GHz, 75 C, and 19 W. This behavior aligns with our CineBench R15 xT observations above where performance would be highest during the start of the test before trailing off.
GPU clock rates when running Witcher 3 would cycle between 950 and 1150 MHz which contributes to the cycling frame rates mentioned above.

Power Consumption
Power consumption is higher across the board on the Intel configuration when compared to AMD particularly when running higher loads. These differences could be due to both the higher initial Turbo Boost potential of the Core i7 CPU when compared to Ryzen 5 and the faster integrated graphics performance when compared to the Radeon RX Vega 7. Running Witcher 3, for example, would consume about 30 percent more power on our Intel unit.

Battery Life
The generally higher power consumption mentioned above takes its toll on battery life. Web browsing on our Intel unit would last just over 6 hours compared to 7.5 hours on the AMD unit when both are on the same Balanced power profile. Charging is also slower than expected at around 2 hours even when Lenovo Rapid Charge is enabled.

Pros
Cons
Verdict — Trading Battery Life And Quieter Fans For Thunderbolt And Faster Graphics
Perhaps the most surprising finding about the Intel version of the ThinkPad L13 Yoga G4 is the steeper-than-expected CPU performance throttling. While we never expect any Core U processor to maintain high Turbo Boost clock rates for extended periods, the Core i7 in this particular Lenovo model would throttle more than on most other laptops with the exact same CPU. This performance deficit mitigates a key advantage point for Intel against AMD especially since the throttling issue is not as severe on the AMD configuration.
Another aspect worth mentioning is the higher power consumption of the Intel version leading to shorter runtimes by 1 to 2 hours. Users who value longer battery life may therefore want to select the AMD version of the ThinkPad L13 Yoga G4 instead.
Unless if you really need the extra graphics performance and Thunderbolt support from Intel, the AMD version of the ThinkPad L13 Yoga G4 should be sufficient for the majority of interested users.
The main reasons for choosing the Intel version of model over AMD are for vPro (instead of AMD PRO), Thunderbolt support, and faster graphics performance and single-thread CPU performance. Otherwise, the AMD SKUs have the upper-hand when it comes to multi-thread CPU performance, battery life, and price.
Price and Availability
Lenovo is not yet shipping the ThinkPad L13 Yoga Gen 4 at the time of publishing. However, CDW is currently shipping our Core i7 configuration for $1419 USD.
