MagyarLenovo ThinkPad T14s G4 Core i7 laptop review: Uphill battle against AMD Ryzen 7
The venerable ThinkPad T14s series is back this year with wide-ranging SKUs encompassing Intel, AMD, IPS, and OLED options. We've already reviewed the AMD and OLED systems and so now is the perfect time to check out an Intel IPS configuration to see how it compares.
Our test unit ships with the Core i7-1365U vPro and 1200p IPS display for approximately $1400 USD. It is one of the more affordable configurations as it excludes some luxuries like WAN, Smart Card, and the 5 MP webcam.
The ThinkPad T14s competes with other 14-inch business subnotebooks like the Dell Latitude 7440, HP EliteBook 845 G10, or Asus ExpertBook B9.

Case
An easy way to distinguish between an Intel configuration from an AMD configuration — aside from their sticker logos — is to look for the Thunderbolt icon next to the USB-C ports. Otherwise, the Intel and AMD configurations share the same chassis design with no other visual differences.
Communication
WLAN performance is consistent and excellent when paired to our Wi-Fi 6E (6 GHz) network. Performance on Wi-Fi 6 (5 GHz) is a bit more shaky as shown by the graph below but it is nonetheless reliable and perfectly serviceable.
Webcam
Our test unit comes configured with a 2 MP webcam instead of a 5 MP as found on our AMD unit. IR is only optional while the privacy slider comes standard.
Maintenance
Display
There are a total of six(!) display options available as follows. Our test unit has been configured with the one in bold which is one of the cheaper options.
- 1920 x 1200, IPS, 300 nits, touchscreen, matte, ~60% sRGB
- 1920 x 1200, IPS, 300 nits, matte, ~60% sRGB
- 2240 x 1400, IPS, 300 nits, matte, ~60% sRGB
- 1920 x 1200, IPS, 400 nits, matte, 100% sRGB
- 2800 x 1800, OLED, 400 nits (500 nits HDR), glossy, 100% DCI-P3
- 1920 x 1200, IPS, 500 nits, touchscreen, matte, 100% sRGB
As shown by our measurements below, opting for the lower-end panel entails noticeable sacrifices to colors and brightness when compared to the higher-end options. We recommend the fourth option with full sRGB coverage at the very least especially for any graphics editing and to improve outdoor visibility.
There are no display options greater than 60 Hz which is a shame as competing 14-inch subnotebooks like the Asus ExpertBook B9 have 90 Hz OLED panels.

The display does not come calibrated with its average grayscale and color deltaE values of 4 and 3.72, respectively. Calibrating it ourselves addresses the overly warm color temperature for more accurate grayscale and colors as shown by our CalMAN screenshots below. Even so, the display still becomes more inaccurate at higher saturation levels due to the narrow color coverage mentioned above.

Performance
Testing Conditions
We set Windows to Performance mode prior to running the benchmarks below. Lenovo Vantage does not have its own set of power profiles to reduce confusion.
Processor
The Core i7-1365U offers just 10 percent faster single-thread performance than the Core i5-1335U. Otherwise, the two CPUs perform almost identically when it comes to multi-thread performance. You'll have to consider the AMD Zen 4 configurations for greater performance.
Performance sustainability is only average. When running CineBench R15 xT in a loop, for example, multi-thread performance would drop by about 20 percent over time to indicate slowing Turbo Boost speeds.

Storage Devices
Our test unit includes a 512 GB Kioxia XG8 KXG8AZNV512G promising sequential read and write rates of up to 7000 MB/s and 5000 MB/s, respectively. The drive in our unit can indeed reach 7000 MB/s, but this rate would only last for a minute or two before it begins to throttle to the 5000 MB/s range as shown by our DiskSpd loop results below. In comparison, the Samsung PM9A1a in the AMD version of our ThinkPad T14s G4 would have no issues maintaining maximum speeds for longer periods. We suspect that the controller on the Kioxia is reaching its temperature ceiling at a faster rate than on the Samsung.

The Iris Xe 96 EUs is due for an upgrade as it has fallen behind recent alternatives from AMD. The Radeon 780M in the AMD version of the ThinkPad 14s G4 can offer 40 to 60 percent faster performance which is not insignificant by any means. Downgrading to the Core i5-1335U configuration with the Iris Xe 80 EUs instead of our Iris Xe 96 EUs will impact graphics performance by 25 to 30 percent.
Interestingly, overall performance remains about the same between battery power, Balanced mode, and Performance mode as shown by our 3DMark 11 results table below.

Emissions
System Noise
Fan noise, or more specifically the lack thereof, is one of the best aspects of the ThinkPad T14s G4. Our Intel unit in particular runs slightly quieter than the AMD configuration when demanding loads are introduced. In other words, the internal fan is able to remain quieter for longer before higher RPMs are needed.

Temperature
Surface temperatures top out at 40 C on the top and bottom (C and D covers) when running demanding loads similar to what we recorded on the AMD version. The hot spots are toward the rear away from the palm rests and many of the commonly used keyboard keys.
(+) The maximum temperature on the upper side is 39.8 °C / 104 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 35.2 °C / 95 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 23.6 °C / 74 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 26.2 °C / 79.2 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (+1.5 °C / 2.7 F).

Stress Test
The CPU would boost to 3.8 GHz, 53 W, and 100 C when initiating Prime95 stress. After about 10 seconds or so, however, the CPU would drop to 2.5 GHz and 23 W in order to maintain a more manageable core temperature of 77 C. The short-lived Turbo Boost potential is common amongst U-series-powered Ultrabooks and it is consistent with our CineBench R15 xT results above.
Core temperature when running Witcher 3 to represent high GPU load would stabilize at 73 C compared to 77 C on the recent Pavilion Plus 14 with the faster Ryzen 7 7840U.

Energy Management
Power Consumption
Our Intel system is slightly more demanding than the AMD version by a few watts when idling on desktop. Extend this by several hours and the minor differences can add up as exemplified by our battery life results in the next section.
Power consumption when initiating CPU-intensive tasks will draw much more power with our Intel unit than an AMD unit due to the generally higher Turbo Boost potential of the Core series. However, the power spike would only last for just a few seconds before consumption normalizes between the Intel and AMD models as shown by our comparison graphs below.
Performance-per-watt is clearly in AMD's favor. Running Witcher 3 or Prime95, for example, demands about the same from each model after accounting for throttling and yet the AMD Ryzen 7 configuration would provide noticeably faster multi-thread CPU performance and graphics performance than our Intel Core i7 configuration.

Battery Life
WLAN runtime is noticeably shorter than on the AMD model by several hours even though battery capacity is the same between them. We're able to record almost 8 hours of real-world browsing compared to over 13 hours on the AMD-based version which is still good but nonetheless underwhelming against the HP EliteBook 845 G10 or Latitude 7440.

Verdict — Tough Competition From AMD
The Core i7 vPro ThinkPad T14s G4 is the fastest Intel configuration available and yet it is still slower than the cheaper Ryzen 7 Pro configuration in both multi-thread CPU performance and graphics performance. Not only that, battery life is actually shorter than the AMD option despite the overall slower performance. These drawbacks alone make it easier to recommend the AMD Ryzen 7 configuration which can be found for $1200 USD or $200 less than our Core i7 review configuration equipped with the same 16 GB of RAM, 512 GB SSD, and 1200p IPS touchscreen.
The Core i7 ThinkPad T14s G4 isn't terrible by any means. Instead, the Intel U-series is simply outclassed by the current crop of AMD Zen 4 CPUs especially when it comes with the impressive Ryzen 7 7840U.
The Intel SKUs benefit from Thunderbolt support, but the AMD options ship with USB4 which supports most Thunderbolt devices anyway like eGPUs and monitors. The benefits of going Intel instead of AMD are therefore very minor for the vast majority of users. Users can save money or get more bang for the buck by going with a Ryzen 7 unit and then configuring with additional auxiliary options like WAN or Smart Card.
Price and Availability
Lenovo is now shipping the ThinkPad T14s in multiple configurations starting at $1110 USD for the Intel SKUs or $920 for the AMD SKUs. Our specific Intel Core i7 configuration retails for around $1400.
