Asus VivoBook Flip 14 TM420IA Ryzen 7 Convertible Review: Core i7 Need Not Apply

Flippin' good. It's another home run for the affordable Asus VivoBook Flip series as this AMD-powered convertible retails is both faster and cheaper than many Intel Core i7 alternatives in the market.

Unveiled earlier this year, the Asus VivoBook Flip 14 TM420 convertible is the successor to last year's VivoBook Flip 14 TP410 series. This latest model introduces both a brand new chassis design and the latest Zen 2 U-series CPUs to be sleeker and faster than before without burning a hole through your wallet. Asus markets its VivoBook series to budget-conscious home users in contrast to the pricier higher-end ZenBook series.

Our configuration here comes with the Ryzen 7 4700U CPU, 8 GB of RAM, 512 GB GB NVMe SSD, and 1080p touchscreen for about $700 USD. Less expensive Ryzen 5 4500U and Ryzen 3 4300U SKUs are also available for while Intel Tiger Lake versions will be coming later in Q4 2020. Competitors include other affordable subnotebook convertibles like the Lenovo IdeaPad Flex, HP Pavilion x360, or Dell Inspiron 2-in-1.

Case

When compared to the older VivoBook Flip 14 TP410, the TM420 is smaller in every dimension while still weighing about the same. Both the base and lid are rigid and just slightly weaker than an HP Envy x360.

Chassis and lid are made of aluminum alloy to feel almost like a ZenBook. Corners and edges are sharper this time around when compared to the last gen model

Display

Though the chassis and innards may be new, Asus is still using the same BOE NV140FHM-N49 touchscreen panel as found on the older VivoBook Flip 14 TP401NA meaning that the visual experience remains the same year-over-year. This IPS panel is notable for its limited colors, average response times, and average contrast ratio to represent a budget display.

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
30.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 11.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
36.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 17.6 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. » 46 % of all devices are better.
This means that the measured response time is similar to 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 18110 (minimum: 5 - maximum: 3846000) Hz was measured.

The display is not bright enough to overcome the glossy overlay and bright ambient lighting when outdoors. Expect a lot of glare even when set to the maximum brightness setting. Remember to disable AMD Vari-Bright or else maximum brightness will automatically drop to just 154 nits when running on battery power.

Performance

 

Processor

CPU performance is faster than any Intel Comet Lake-U or Ice Lake-powered laptop at the moment. Performance over time dips by about 20 percent as shown by our CineBench R15 xT loop test results below, but clock rates eventually recover and stabilize at the 1000-point range.

See our main page on the Ryzen 7 4700U for more technical information and benchmark comparisons.

PCMark results are strong and consistently ahead of many 14-inch Intel Ice Lake or Comet lake-U Ultrabooks. We didn't experience any issues with our unit save for it being unable to wake from sleep one time that we weren't able to reliably reproduce.

Storage Devices

The Samsung PM991 is a budget mid-range NVMe SSD that pairs well with the budget mid-range VivoBook. Its drawback is the relatively slow average sequential write rate of about 800 MB/s whereas pricier NVMe drives like the PM981a can be 2x to 3x faster.

See our table of HDDs and SSDs for more benchmark comparisons.

GPU Performance

According to 3DMark, the integrated Radeon RX Vega 7 performs as well as most laptops equipped with the 10 W GeForce MX150 while being about 10 to 15 percent faster than the Core i7-1065G7 and its integrated Iris Plus G7. Real-world gaming performance still favors the GeForce GPU due to its more mature drivers, but AMD has been steadily optimizing its drivers to narrow the gap.

See our dedicated page on the Radeon RX Vega 7 for more technical information and benchmarks.

System Noise

Day-to-day loads like browsing or word processing will not induce any bothersome pulsing behavior. At most, we're able to record a high of just 31.7 dB(A) which is just barely audible in most environments. Higher loads like gaming will induce a fan noise of 41.3 dB(A) to be louder than most Ultrabooks with slower Intel UHD Graphics only.

Cooling solution consists of a single long heat pipe and a relatively large ~55 to ~60 mm fan

Temperature

Surface temperatures are noticeably warmer on the keyboard keys and along the left edge near the exhaust grilles as shown by our temperature maps below. The bottom panel can become quite warm at 43 C when under high processing loads partly because there are no ventilation grilles on the bottom panel.

Stress Test

Running Prime95 would boost CPU clock rates to 4.9 GHz for just a couple of seconds before stabilizing at 3.5 GHz and 76 C for a few minutes thereafter. Clock rates and temperature eventually settle at 3 GHz and 69 C, respectively. Faster stable clock rates may have been possible, but it would have likely caused skin temperatures or fan noise to be higher than what Asus was aiming for.

Energy Management

Power Consumption

The latest Ryzen laptops are able to offer higher performance-per-Watt than any Intel Core U-series laptop at the moment especially when it comes to processor performance. Running Witcher 3, for example, consumes about 30 percent more than the Core i7-1065G7-powered Asus ZenBook 13 while offering both 15 percent higher graphics performance and over 100 percent faster CPU multi-thread performance.

We're able to measure a temporary maximum consumption of 45 W from the small (~5.4 x 5.4 x 3 cm) 45 W AC adapter when running both Prime95 and FurMark simultaneously as shown by our graphs below. Consumption drops  since maximum boost clock rates are not sustainable over long periods.

Battery Life

Runtimes are longer than expected despite the relatively small 42 Wh battery. Our system would last for 8 hours when looping web pages to be just enough for a full day of use.

Charging from empty to full capacity takes about 1.5 hours. Unfortunately, the USB-C port cannot be used to recharge the system.

Verdict

In review: Asus VivoBook Flip 14 TM420IA. Test unit provided by Asus

The AMD-powered 2020 VivoBook Flip couldn't have launched at a better time. Intel's 10th gen Ice Lake and Comet Lake-U platforms have already grown stale against the Zen 2 series in terms of raw performance and the generally lower starting prices of AMD laptops make Core i7 alternatives even less attractive at the moment. Intel is set to regain some lost momentum later this year when Tiger Lake becomes available, but AMD laptops like the our VivoBook will have free reign until then.

As for the laptop itself, users won't be sacrificing performance at all despite the affordable price point. Instead, the hardware will lack a few luxurious features like Thunderbolt 3, USB-C charging, Wi-Fi 6, and an IR camera. It's biggest cut corner is to the display and its narrow gamut which pales in comparison to the ZenBook series. Otherwise, this is a fast and well-built budget laptop fit for students, home multimedia use, and the occasional travel.

An inexpensive convertible that can perform faster than most others in its size category costing hundreds more. It's above average on almost all fronts save for the mediocre display.
