Lenovo ThinkPad T490 Laptop Review: The Comet Lake-U Update

Small CPU refresh. Lenovo is refreshing its ThinkPad T490 one last time before the impending launch of the ThinkPad T14. The update is so minor, however, that you can opt for last year's ThinkPad T490 or just wait for the ThinkPad T14 instead without missing all that much.

Early last month, Lenovo unveiled the ThinkPad T14 and ThinkPad T15 as successors to the ThinkPad T490 and ThinkPad T590, respectively. We've already reviewed the T490 in multiple Whiskey Lake-U SKUs over the past year. Now, this latest Comet Lake-U configuration will likely be the last refresh before the aforementioned ThinkPad T14/15 series hits the market.

The unit here comes equipped with the Core i7-10510U CPU, 32 GB of RAM, and a FHD touchscreen for a retail price of $1600 USD on CUKUSA.com. Its aftermarket Sabrent Rocket Q NVMe SSD is courtesy of our reseller and so users shouldn't expect this same brand if purchasing the T490 directly from Lenovo. See our existing reviews on the ThinkPad T490 to learn more about the chassis and its features as this page will instead focus on the display and new CPU.

Display

Our latest T490 unit uses a different panel than all the other T490 units that we've tested thus far. Whereas the other units had QHD B140QAN02.0 or FHD NE140FHM-N61 panels, the unit here uses an FHD R140NWF5 RA panel. This panel is the inferior FHD option as it is dimmer (300 nits vs 400 nits) and with more limited colors (61 percent sRGB vs 92 percent sRGB) than on the NE140FHM-N61. Pulse-width modulation is also now present on nearly all brightness levels. On the other hand, response times are faster this time around for less noticeable ghosting.

There is slight-moderate uneven backlight bleeding on our test unit as shown by the picture below. Thankfully, it is unnoticeable during day-to-day browsing or word processing.

Display options range from 768p to 1080p and 1440p with matte or glossy options

* ... smaller is better

Color space is limited to just 61 percent of sRGB compared to >95 percent on high-end Ultrabooks like the ZenBook S13 or HP Spectre 13. Users will have to configure the ThinkPad T490 with higher-end panel options for deeper and more accurate colors.

Further measurements with an X-Rite colorimeter reveal an accurate grayscale out of the box. Calibrating the panel ourselves improves the average grayscale DeltaE even further from 2.8 to 1.1. Color accuracy, however, remains average at best due to the limited color coverage mentioned above. Blue is especially inaccurate relative to the other colors tested.

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
28 ms ... rise ↗ and fall ↘ combined↗ 14.8 ms rise
↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
47.2 ms ... rise ↗ and fall ↘ combined↗ 26 ms rise
↘ 21.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 75 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.5 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 detected 980.4 Hz ≤ 99 % brightness setting

The display backlight flickers at 980.4 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 980.4 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17067 (minimum: 5 - maximum: 2500000) Hz was measured.

Outdoors visibility is worse than the other T490 laptops we've tested since the screen is dimmer this time around. We recommend opting for the 400-nit option or even alternatives like the XPS 13 or HP EliteBook x360 1040 G5 which have much brighter displays.

Performance

Lenovo offers the 10th gen Core i5-10210U or Core i7-10510U CPU to replace the older 8th gen Core i5-8265U or Core i7-8565U, respectively. While RAM is now faster (DDR4-2666), the optional GeForce MX250 graphics remain the same. It's a shame that there is no Core i7-10710U option as that would have have boosted the multi-thread performance of the system much further. AMD Ryzen options are reserved for the ThinkPad T495 or T495s series.

LatencyMon shows no recurring DPC latency issues even with Wi-Fi enabled.

 

Processor

CPU performance is where we expect it to be at within 3 percent of the average Core i7-10510U in our database. Unfortunately, the actual processor itself is underwhelming as it's only marginally faster than the last generation Core i7-8565U or Core i7-8550U at best. AMD's competing Ryzen 7 3700U is also comparable in multi-threaded workloads while costing less. A Core i7-10710U option would have offered a more significant gen-to-gen performance boost.

See our dedicated page on the Core i7-10510U for more technical information and benchmark comparisons.

System Performance

Average PCMark results are higher than than every 14-inch ThinkPad T series laptop thus far including last year's Whiskey Lake-U SKU equipped with faster GeForce MX250 graphics. This is likely partly attributed to the aftermarket Sabrent Rocket Q NVMe SSD that CUKUSA has outfitted onto our test unit.

We experienced no notable software or hardware glitches during our time with the unit.

Storage Devices

Only one internal M.2 2280 slot is available whereas the older ThinkPad T480 has a secondary 2.5-inch SATA III bay. The Sabrent Rocket Q SSD is more comparable to the Samsung PM981a rather than the slower SK Hynix PC501 or the Toshiba HG6 series.

GPU Performance

Despite being a sparkly new Intel 10th gen CPU, the Comet Lake-U series still uses the years old UHD Graphics 620. Graphics performance is only about 15 to 20 percent faster than the average UHD Graphics 620 in our database which is essentially unnoticeable during real-world loads. You'll have to consider SKUs with the GeForce MX250 or the RX Vega 10 if you want tangible graphics boosts.

See our page on the UHD Graphics 620 for more benchmark comparisons.

Emissions

System Noise

As expected, fan noise is close to what we recorded on the Whiskey Lake-U version of the ThinkPad T490 and even the older ThinkPad T480. Running the first benchmark scene of 3DMark 06 would top out at about 35.5 dB(A) while higher loads like Prime95 would cause fan noise to spike temporarily to 38 dB(A). Otherwise, the system will almost always be completely silent or at least very quiet at only 29.2 dB(A) during undemanding loads like browsing or video streaming.

We can notice no electronic noise or coil whine from our test unit.

Temperature

Hot spots when idling range from 30 C to 34 C or 46 C to 64 C when under extreme processing loads. We don't recommend running demanding loads for long periods without a nearby table because the bottom of the laptop can become very warm.

Stress Test

Running Prime95 causes the CPU to spike to 4.2 GHz for just a couple of seconds before falling to 3.5 GHz and at a core temperature of 97 C. After about 20 seconds, performance drops even further before stabilizing at 3 GHz and 90 C. Running both Prime95 and FurMark simultaneously will throttle the CPU down to 1.3 GHz with periodic dips to just 400 MHz. These high core temperatures definitely explain the warmer-than-expected surface temperatures recorded above.

Running on battery power will not limit performance. A 3DMark 11 run on batteries returns Physics and Graphics scores of 8799 and 1947 points, respectively, compared to 8995 and 1942 points when on mains.

Power Consumption

Running the first benchmark scene of 3DMark 06 consumes an average of 35 W to be similar to what we recorded on the ThinkPad T495s with the Ryzen 7 Pro 3700U. This is notable because the RX Vega 10 GPU in the Ryzen 7 3700U is able to offer roughly two times the graphics performance of our UHD Graphics 620 without consuming more power.

We're able to measure a high of 68 W from the small (~10.4 x 4.8 x 3 cm) 65 W AC adapter when initiating both Prime95 and FurMark simultaneously. The high consumption rate is only temporary as shown by the graphs below.

Battery Life

Battery capacity has dropped from 72 Wh on the ThinkPad T480 to just 50 Wh on the T490. Consequently, WLAN runtimes are about five hours shorter on the T490 for a total of "only" 8.5 hours. While still excellent, don't expect ridiculously long runtimes unless if a secondary battery is attached.

Recharging from empty to full capacity with the included AC adapter takes approximately 1.5 hours.

As noted in our initial overview of the series, the raw performance benefits of Comet Lake-U over Whiskey Lake-U are marginal save for the hexa-core Core i7-10710U which is unfortunately not available on the ThinkPad T490. Instead, users can only configure up to the quad-core Core i7-10510U.

Aside from the CPU update, the Comet Lake-U ThinkPad T490 SKUs have faster RAM (DDR4-2400 to DDR4-2666) and Wi-Fi (802.11ac to 802.11ax) than the older Whiskey Lake-U SKUs. The gen-to-gen differences, however, are again marginal at best.

To maximize value, we recommend an older Whiskey Lake-U configuration with one of Lenovo's brighter display options. The T490 offers 400-nit FHD and 500-nit WQHD panels to be brighter than the 300-nit display we have here. Investing in a better display will be much more noticeable than the jump from Intel 8th gen to 10th gen in this regard.

The CPU, RAM, and WLAN changes are minor upgrades over last year's model. If you want a 14-inch T series ThinkPad, then wait for the ThinkPad T14 or just go with a Whiskey Lake-U T490 configuration.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
