Lenovo has primarily targeted small and medium-sized businesses with the ThinkBook 14s Yoga ITL, a business convertible with a 14-inch screen. A Tiger Lake CPU powers the device, and in this article, I’ll analyse the laptop’s Tiger Lake CPU to get a good idea of its overall performance and determine how good it is and whether it’s worth buying.
A Performance Analysis of the Lenovo ThinkBook 14s Yoga ITL with an Intel Core i7 Processor
The ThinkBook 14s Yoga from Lenovo is a 14-inch business laptop with adequate processing power for web and office apps. It starts at $900 and comes in a variety of combinations. The one I’m testing out today, though, has a quad-core Tiger Lake Intel Core i7-1165G7 processor.
Context for Testing
Users can select between many performance settings using the preinstalled Lenovo Vantage software, including “smart cooling,” “maximum performance,” and “battery saving mode.” I used the “smart cooling” setting to conduct all of my tests. Additionally, certain benchmarks were finished in “maximum performance” mode.
Tiger Lake’s Core i7-1165G7 quad-core processor runs at a base frequency of 2.8 GHz. This can be raised by the turbo to 4.1 GHz (for all four cores) or even 4.7 GHz (for a single core). Hyperthreading, which uses two threads per core, is also supported.
During my Cinebench multi-threaded testing, the processor briefly ran at 4.1 GHz before dipping to 1.5 – 3.5 GHz. At 1.7 to 4.7 GHz, the single-thread tests were completed. When using a battery, the clock rates are much reduced.
I did the Cinebench R15 multi-thread test constantly for at least 30 minutes to determine whether the CPU turbo is utilised continuously when operating on mains. The test’s early minutes were the only time the high clock rate was attained. The CPU then ran at a slight increase over its base clock rate. Continuous turbo clock rates were possible in the “maximum performance” mode.
Throughout my testing period, there were no problems with the quick and seamless system. For office and internet tasks, the processor provides performance that is more than adequate. The GPU even permits the sporadic use of video games. The positive PCMark findings support my initial hypothesis. The ThinkBook 14s’ RAM (DDR4-3200) operates in dual-channel mode. Lenovo selected a mix of soldered and non-soldered modules, each with 8 GB. This implies that RAM might be increased to a maximum of 40 GB if required.
DPC latencies in my standardised Latency Monitor test (web browsing, 4K video display, and Prime95 high load) did not reveal any anomalies. The system appears to be appropriate for real-time video and audio processing.
The graphics component is handled by Intel’s inbuilt Iris Xe Graphics G7 96EU GPU. It can run up to 1300 MHz and supports DirectX 12. The GPU continues to perform below its potential in both the 3DMark benchmarks and in real-world (gaming) situations.
Fast RAM is advantageous for contemporary iGPUs from Intel and AMD. Performance is increased in direct proportion to RAM speed. As a result, these laptops frequently have faster LPDDR4X-4267 RAM modules. The ThinkBook 14s “only” has slower DDR4-3200 RAM, which prevents the iGPU from operating at its peak level of graphics performance.
To be clear, however, the integrated GPU is not subpar. Its benchmark results outperform those of the preceding GPU generation (Ice Lake) by a wide margin. The Ryzen 4000 iteration of AMD’s Vega-8 GPU can still be outperformed by the Iris graphics processor. The graphics performance is unaffected by the “maximum performance” mode.
Gaming was not a design goal while creating the Lenovo ThinkBook 14s Yoga ITL convertible. Nevertheless, even at low resolution and quality settings, its CPU/GPU combo can smoothly display a large number of titles in my library. Better circumstances are available for playing games that are only somewhat hardware-demanding. The “maximum performance” mode is beneficial for games that rely heavily on the CPU.
I played “The Witcher 3” for 60 minutes at Full-HD resolution with the highest quality settings to determine whether the refresh rates held steady over time. This time, the character was not moved. Performance wasn’t diminished in any way. However, since the character was not moving, frame rates could not be consistently achieved. However, when moving around, frame rates held stable at lower graphical settings but not as much at higher graphical settings.
|The Witcher 3 (2015)||64.7||42.2||20.9||11.7|
|Dota 2 Reborn (2015)||78.1||54.9||36.6||34.6|
|X-Plane 11.11 (2018)||40.9||33.3||30.2||NIL|
|Far Cry 5 (2018)||36||17||16||15|
|Shadow of the Tomb Raider (2018)||38||13||12||10|

My Lenovo test device is outfitted with a 512-GB SK Hynix NVMe SSD (M.2 2242). These devices’ transfer rates are excellent. A user could add a second NVMe SSD (M.2 2280) to the system.
Across all load levels, the Lenovo ThinkBook 14s Yoga ITL produces very little noise. The cooling fan is either entirely off or only operating at modest rates. In the Witcher 3 stress test, load test) the fan noise was barely audible.
During the majority of my stress test, which involved running Prime95 and FurMark for at least an hour, the CPU and GPU clocked between 600 and 1100 MHz and 550 and 650 MHz, respectively. I didn’t measure clock rates of 2.8 GHz (CPU) and 1.3 GHz (GPU) until the test’s early stages.
An extreme circumstance is represented by the stress test. It is used to determine how the system responds to the highest possible load. The convertible doesn’t really get hot. Even with a full load, the temperatures at all measurement sites are far below 40 °C. When used regularly, the outcomes are significantly lower.

The Lenovo ThinkBook 14s Yoga completed my Wi-Fi test with a runtime of 10:22 hours and my video test with a runtime of 13:56 hours (Film: Guardians of the Galaxy 2 H.264, FHD). The energy-saving mode is disabled, and the display brightness is set to around 150 cd/m2 for the duration of these tests. The wireless module is turned off throughout the video test as well.
While the ThinkBook uses more power than its rivals while idle (9.1 watts maximum), it is more energy-efficient under full load (stress test), using only 39 watts. Because the CPU turbo is not active, the latter occurs. Power usage from Prime95 alone is 68 watts. The Type-C USB AC adaptor that comes with it has a 65-watt rated output.
I had a positive overall experience with the Lenovo ThinkBook 14s Yoga ITL, which is a well-rounded business convertible. The device is an excellent solution for all potential flexible business usage scenarios thanks to the Core-i7-1165G7 processor, 16 GB of RAM (dual channel mode, 8 GB onboard + 8 GB module, max 40 GB), and a 512-GB NVMe SSD. Because of the RAM’s selection (DDR4-3299), the integrated GPU (Iris Xe Graphics G7 96EU), performs below its potential. I appreciate you reading this article.
