MagyarRobo and Kala TW220 2-in-1 OLED tablet review: Outperforming the Microsoft Surface Go 3
The TW220 is the latest flagship Windows 11 tablet from the Chinese-American company Robo and Kala. It's one of the very few Windows tablets to ship with an ARM SoC much less a Qualcomm Snapdragon 8cx Gen 3 with integrated Adreno 690 graphics. As such, it competes directly with the Microsoft Surface series including the recent Surface Pro 9 ARM which uses the exact same Qualcomm processor.
Beyond its uncommon SoC, the specifications read like a high-end tablet including the 16:10 2560 x 1600 OLED touchscreen with 98% DCI-P3 colors, 16 GB LPDDR4X RAM, 512 GB NVMe SSD, and detachable keyboard base all for $599 USD or hundreds of dollars less than a typical Core-powered Surface Pro.

Case — Strong First Impressions
The aluminum chassis is rigid for solid first impressions which is impressive considering it is both thinner and lighter than the Surface Pro and with narrower bezels as well. The keyboard base is also strong, but its connection pins detach from the tablet too easily.
The tablet itself weighs 712 g while the keyboard base adds another 350 g for a total of 1.06 kg. It's lighter than most if not all Surface models including the smaller Surface Go 3.
Connectivity
The two USB-C ports each support DisplayPort and charging. We're able to output up to a maximum of 4K and 60 Hz at an 8-bit color depth. There is no headphone jack.
Communication
A Qualcomm WCN685x comes standard for both Wi-Fi 6 and Wi-Fi 6E connectivity. We experienced no issues when paired to our Asus AXE11000 6 GHz network.
Webcam
At 13 MP, the webcam on the TW220 is of higher resolution than the webcams on both the Surface Pro 9 (10 MP) and Surface Go 3 (8 MP). IR is built-in for Windows Hello support, but a privacy shutter is absent.
Accessories And Warranty
The retail box includes the backlit removable keyboard base and 4096-level pressure smart pen. The keyboard base has its own internal battery and can connect to the tablet wirelessly via Bluetooth or physically via connection pins. The base integrates no ports and so it can only charge when physically connected to the tablet.
The standard one-year limited manufacturer warranty applies.
Input Devices
Keyboard
Detachable keyboards for tablets are almost always worse than the keyboards on traditional laptops. The keyboard for the TW220, however, is actually not bad. Key feedback is uniform and crisp and the 1.3 mm travel is standard. Unfortunately, the keys feel somewhat stiff and so it takes more effort from the fingers to push down and register an input.
Touchpad
The clickpad is 11 x 6.5 cm which is larger than the 10.2 x 5.8 cm clickpad on the Surface Pro keyboard. Feedback when clicking is shallow but firmer than on most laptops. Clatter is subsequently sharp and loud, however.
Display — OLED
The TW220 is the first device in our database to utilize a Sharp RM69380 OLED panel in contrast to the LG Philips LP129WT2 or BOE NV105WAM IPS panels on the Surface Pro 9 or Surface Go 3, respectively. OLED brings inherent advantages over IPS including faster black-white response times to reduce ghosting, deeper black levels, wider color ranges, and better brightness uniformity.

The display does not come pre-calibrated despite it being a high quality OLED panel. It targets P3, but the overly cool color temperature means colors are inaccurate at lower saturation levels as shown by our CalMAN measurements below.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 60.6 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 60.6 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 60.6 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17903 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Flickering is present on all brightness levels including the 100 percent setting. We're able to detect a flickering of 60 Hz much like on most other tablets, laptops, or smartphones with OLED displays.
The display of the Robo and Kala is actually brighter than the displays on the Surface Pro 9 or Surface Go 3 by 25 to 35 percent. Nonetheless, it's still recommended to work under shade in order to reduce glare and maximize color vibrancy.
Performance — Faster Than The Core i3 In Multi-Threaded Scenarios
Testing Conditions
We set Windows to Performance mode prior to running the benchmarks below. It's worth noting that many applications fail to launch on Windows ARM including many of our usual benchmark applications. LatencyMon, PCMark 10, 3DMark, i1Profiler, BaseMark, Geekbench 5.4, GPUScore Sacred Path, 3DMark 06, HWiNFO sensor readings, and certain Windows Batch files are just some of the problematic applications we experienced during testing.
Processor
Raw multi-thread performance is consistently ahead of the three-year old Core i5-1035G1 while the opposite is true for single-threaded workloads. Demanding tasks like 4K encoding or Blender are slower than the Core i5 meaning that power users should still want to consider a Core i7 Microsoft Surface Pro. At least the Snapdragon 8cx Gen 3 is much better than the old Core m3 series on the abysmally slow Surface Go 2.
When stressed under Prime95, CPU clock rates would be as high as 2.7 GHz for the first several seconds before falling and stabilizing at 2.1 GHz after a few minutes.

System Performance
Subjectively, Windows 11 runs smoothly and responsively on the Snapdragon SoC and we experienced no BSODs during testing. With that said, keep in mind that most applications are run via emulation and so the chances for incompatibility are high.
Navigating the OS is not as smooth as on most Android tablets due in part to the 60 Hz refresh rate of the display. Most tablets these days have already moved on to higher refresh rates such as the 120 Hz display of the Lenovo P11.

GPU Performance
Users shouldn't expect the integrated Adreno 690 to outperform the common Iris Xe or Radeon RX Vega series since it runs on a lower power envelope and is passively cooled. Even so, 3DMark 11 reveals the Qualcomm GPU to at least be faster than the very old UHD Graphics series. Perhaps most importantly, the tablet is able to play 4K video at 60 FPS without any dropped frames.

Gaming Performance
The TW220 is more fit for game streaming rather than native gaming. With that said, gaming performance sits in between the slower UHD Graphics and faster Iris Xe 80 EUs as found on most Core i5 laptops. Many games would fail to launch or crash on certain settings, anyway.

Power Consumption
Overall power consumption is slightly higher than the Surface Go 3 while being well below the faster Core i7-powered Surface Pro 9. The OLED touchscreen is noticeably more power demanding as it alone can draw up to 9 W depending on the color and brightness setting. It may offer deeper colors and a brighter backlight than a Surface model, but owners are paying for it with higher power consumption.

Pros
Cons
Verdict — A Great Midway Point Between The Surface Pro And Surface Go
The best aspects of the Robo and Kala TW220 are its OLED touchscreen, decent ARM performance, and relatively affordable asking price for a well-built aluminum chassis and keyboard base. The OLED display in particular helps to differentiate the TW220 from the competing Surface Pro and Surface Go series and it is a highlight of the model. Users who can appreciate or exploit the wider colors and deeper black levels of OLED will find the TW220 more valuable than most other Windows tablets.
If you can deal with limitations of Windows ARM, then the Robo and Kala TW220 would make for an affordable alternative to the Surface Go 3 or even the Surface Pro 9 if you don't need the horsepower of an Intel Core i7.
For future models, we would like to see the display come pre-calibrated so owners can enjoy accurate OLED colors right out of the box. The keyboard connection pins could be stronger and additional connectivity options would be appreciated including MicroSD or LTE/5G options. Certain compatibility issues are inevitable with ARM and so an alternative model with Intel Core CPUs may attract a wider pool of interested buyers. For basic tasks like browsing, emailing, and streaming, however, the TW220 is one of the most effective Windows tablets we've seen for the price especially when compared to the smaller Surface Go series.
