System Performance

It’s been a long time coming for Chuwi to make the leap from Atom to Core. Intel historically also likes to ensure it has strong product separation in its lineup, so the jump from Atom to Core comes with more performance, but also a sharply higher price. That being said, the latest Gemini Lake based Celerons have made some significant gains, so there is a question of what kind of performance delta there will be between a dual-core Skylake-Y based Core m3 compared to a Goldmont Plus Celeron with four actual cores.

To see how the Chuwi AeroBook performs, it was run through our Laptop workload. For our graphs a variety of devices were chosen to compare it to. The Chuwi LapBook 12.3 is the older Apollo Lake N3450, with four Atom cores from 1.1 to 2.2 GHz. The Chuwi LapBook SE is the latest Gemini Lake N4100, featuring four updated Atom cores from 1.1 to 2.4 GHz. Both of these notebooks cost less. The Microsoft Surface Go features a Y-Series Kaby Lake Pentium 4415Y, but being a Pentium it offers no Turbo at all, so it’s just a 1.6 GHz CPU. The HP Spectre Folio is a Core i7-8500Y, and while being far more expensive, it should show the maximum capabilities of the latest Amber Lake Y Series processor. Finally, the Surface Pro 6 is there to give a reference as to where these fanless devices stack up against a 15-Watt U series Kaby Lake-R with four cores. Once again it’s not direct competition, but was included just to see where these Y series compare against a U series that is also fanless.

UL’s PCMark suite tests all aspects of a system, with varying workloads depending on the scenario. Some are more stressful on the GPU, such as the Content Creation, and it gives a nice overall look at total system performance including the memory and storage subsystems. There’s no doubt that the move to a Core m3 processor has been a nice bump in performance, easily outclassing the earlier Atom powered Chuwi notebooks. Performance is well off the Amber Lake Spectre Folio though, so while it’s great to see Chuwi move to Core, it would have been nice to see them utilize a more recent version.


Cinebench R15 - Single-Threaded Benchmark

Cinebench R15 - Multi-Threaded Benchmark

Cinebench is a purely CPU task, and is a great tool because it offers both single-threaded and multi-threaded workloads. The AeroBook once again surpasses the older Atom based Chuwi laptops handily, especially in single-threaded where Core is so much more powerful. On the multi-threaded test the Gemini Lake claws back some of that gap though since it does offer four cores compared to just two on the AeroBook. Four Gemini Lake cores are quicker than two Kaby Lake cores in the Surface Go because the Pentium, despite being a Core architecture, offers no Turbo, but the Core m3 in the AeroBook does offer some boost up to 2.2 GHz and can win the day. However, all of these Y series and Atom powered notebooks are far below the performance of a quad-core U series.

Similar to Cinebench, x264 uses the CPU to encode video and works well with more cores. Once again the Core m3 in the AeroBook offers a nice performance bump over the previous models, but all of these are surpassed dramatically by the Core i5-8250U in the Surface Pro 6.

Web Results

Web workloads tend to be short, and Intel’s aggressive pursuit of ramping up to their maximum Turbo via their Speed Shift mechanism has helped tremendously here. Web is influenced heavily by the browser as well, so for consistency we test with Microsoft Edge. Microsoft is currently migrating away from their EdgeHTML rendering engine to Chromium though, and once they do that we’ll refresh our tests with updated ones.

There is a definite gap where the AeroBook slots in. The 2.2 GHz maximum Turbo helps ensure that in light workloads the Core m3 can stay ahead of the Pentium and Celerons, but there’s also a massive gap to the latest Amber Lake Y series in the HP Spectre.

System Performance Conclusion

Despite Chuwi not leveraging the latest Amber Lake processors in the AeroBook, they’ve still added in some noticeable performance with the move away from Atom. Unlike the Surface Go, which offers a Kaby Lake based Pentium, the Core m3-6Y30 does offer a mild Turbo boost to 2.2 GHz, which makes all of the difference compared to Atom. The Pentium 4415Y with just two Kaby Lake cores at 1.6 GHz would trade blows with the four Goldmont Plus Atom cores in the LapBook SE, but the AeroBook, with even just that slight Turbo, easily jumps ahead and stays ahead in pretty much every task.

    Ah, this article mentions that it wakes up when sleeping, but not when hibernated:

    I have had hibernated laptops wake up for windows updates before, it seems to be a quite new 'feature'.
  • Rookierookie - Sunday, June 23, 2019 - link

    They do a good job of waking you up in the middle of the night.

    Windows update 1903 wakes my laptop from sleep. First time in the life of that 2015 laptop

    "After a bit of howling and screaming they did offer me to send it to HongKong for a free replacement, and I am torn between using it just on external power or actually see if it gets back fixed."

    That right there should be a huge red flag for anyone considering Chuwi. If they're selling it in North America, then there should be somewhere I can send it for repair in North America. If they don't want to do that, then they should be cross-shipping (for free) at the very least.

    Even with weird / intense usage, it should take a *lot* longer than a year for a battery to swell like that. It was definitely a manufacturing fault.
  • StormyParis - Friday, June 21, 2019 - link

    Can you keep using it ? I've had huge durability issues with 3rd-tier Chinese OEMs (Teclast and Chuwi esp., Cube has been OK for me) and according to fellow complainers (a highly representative sample /s) on Techtablets' youtube channel, I'm not alone.

    They've managed to make stuff that's OK out of the box (it wasn't, a few years ago). Now it seems the things are still fragile, especially with iffy connectors and batteries.

    I've had no issues whatsoever with 10+ XIaomi devices, and since they're barely more expensive than Teclast Chuwi et al., I'm sticking with Xiaomi for now.

    My Teclast T8 tablet's still in good shape after 15 months; but I went with a lower tier Chinese maker because I don't use my tablet much and didn't want to pay apple/samsung prices; but wanted something with a higher DPI display than Amazon's race to the bottom Kindles.

    I managed to keep my 8" Dell android tablet for about 4 years; despite the model I got being cursed with a highly fragile usb port so I'm not overly concerned about general breakableness.

    There's a good chance I would buy this laptop apart from 1 thing:
    I do NOT buy laptops with glossy screens !!
  • eastcoast_pete - Friday, June 21, 2019 - link

    Looks nice enough. The main no-go for me is the low battery life. Also, how long do Chuwi's keyboards and track pads last?
