Powering the Chuwi LapBook 14.1: Intel Apollo Lake

Intel’s Atom processor is their low-cost offering, with a smaller die size than Intel’s Core series, allowing them to sell them for less money, but keep their margins up. Atom has had a bit of a roller coaster of a ride over the last several years. When it launched in 2008, it was an in-order design, offering low power, but also low performance. It was originally on the 5-year cadence that Intel was still doing with their main CPUs as well, which really made the original Atom long in the tooth, despite several process changes along the way.

Eventually Intel saw the threat of ARM processors, and tried to speed up the cadence of Atom so that it could be used in thin and light tablets, as well as smartphones. We saw some brief success with Atom, partially due to a strategy of contra-revenue, and partially because Windows RT was a failure, but with Intel never gaining a foothold in smartphones and basically only available in Windows tablets, Intel made the decision to cancel the Broxton tablet platform completely. This was a bit of a shock, and I’m sure it caught a lot of their partners a bit flat footed, since they had devices being sold with Cherry Trail that would never get an update.

But this didn’t impact the low-end PC market, because Intel was moving forward with their PC platform, which they dubbed Apollo Lake. The new 14 nm successor to Airmont, named Goldmont, was going to live on, albeit in less devices. Much of the confusion about the death of Atom has to do with just how many products it was in.

So, the low-end PC market was still going to go ahead, with Intel focusing on its strengths, despite the decrease in the PC market, rather than push a new Atom against the latest ARM products in tablets and phones. While this retrenching by Intel likely seemed like a good idea for them at the time, Microsoft’s announcement that Windows 10 will support ARM processors with x86 support, surely did not make them happy. Intel is likely to get the ARM competition against Atom they never wanted, but we’ll have to wait and see how the Qualcomm Snapdragon 835 compares later this year.

That brings up back to the present, which is the Chuwi Lapbook 14.1, which run on the Intel Celeron N3450, and despite the name Celeron, this is most certainly an Apollo Lake platform featuring the Intel Atom Goldmont core. Apollo Lake was first publicly announced at IDF in 2016, and it offers some nice advancements over the Braswell PC platform it replaces. The main change should help performance, with Goldmont cores replacing Airmont cores, but also with Gen 9 graphics replacing Gen 8 in Braswell.

Much of the changes with Goldmont were about improving the out-of-order execution compared to Silvermont, with a wider decoder, better branch prediction, and a larger out-of-order execution window. Goldmont can perform one load and one store per cycle, and it can execute up to three simple integer ALU operations per cycle. There’s new instruction support for hashing with SHA1 and SHA256, and there’s new support for the RDSEED instruction. The graphics are also improved, with Gen 9 offering better performance than Gen 8, as well as features like Quick Sync for H.265, and low-power H.264 encode.

Overall, Intel’s previous marketing materials have outlined what kind of performance gains to expect:

Apollo Lake Mobile Performance: Pentium N4200 vs. Pentium N3710
CPU Performance +30%
GPU Performance +45%

With a lower bill of materials, higher performance, and lower power consumption, Apollo Lake is certainly a nice step forward. It remains to be seen just how competitive it will be, and Atom is still a significant step down in performance from Core, even at similar TDP numbers. It remains to be seen if Apollo Lake will be competitive with ARM offerings, and we should have a nice ability to test that later this year.

    Here's a link to a reviewer that tested the Lapbook with Ubuntu:

    http://www.cnx-software.com/2017/02/07/installing-...

    The results look promising.

    If I could don my tin hat for only a few seconds...Has anyone ever looked at the outbound traffic on these lesser known Chinese designed electronics? There was some controversy with Xiaomi router traffic even iirc.
  • BrokenCrayons - Friday, March 10, 2017 - link

    A quick search didn't turn up anything. I don't think they're selling in large enough numbers to attract a lot of interest in sniffing their outbound traffic. It's a reasonable concern, but I don't think Chuwi would actively attempt to perform mass data collection. That's a pretty widely cast net that wouldn't reap much value because you're probably looking at largely home users. The data collection would be almost entirely uninteresting. Maybe some social networking, shopping and general web browsing, someone's hidden inappropriate photos and videos...that kind of thing isn't worth a lot unless you have a specific target in mind and in that case its more prudent to isolate that individual rather than everyone buying your products. Probably the best you'd get is access to someone's personal finances and a deep enough investigation would do a lot of damage to business interests. It's really worth more to establish a good brand reputation and land decent numbers of sales than it is to go through the trouble of getting one or two generations of hardware out there to a small number of people that probably are collectively deep in debt and have little liquid cash.

    I think the concern would lay more on the government's involvement (The Chinese government is involved with virtually all exported electronics). I agree with every single thing you wrote, but Chinese businesses don't all exist for the sole purpose of making money.

    Good point tipoo

    This article just today and all the turmoil at Samsung and S Korea makes me think we should be looking out for malware popping up in other places

    Even places we have considered to be quite reliable up till now

    https://arstechnica.com/security/2017/03/preinstal...

    Things seem to be escalating but I'm sure the CIA will put a start to any malware threats to this Country (LOL)
  • Murloc - Saturday, March 11, 2017 - link

    to make such low costs devices you buy standard chips so I don't think they can put anything in it.

    If chinese-designed chips have espionage software in them, then a bunch of the network infrastructure we rely on is bugged because huawei is everywhere in them. Also phones that use mediatek devices.

    So worrying doesn't make sense, also because it's well-known from the various leaks and stuxnet that the NSA and the CIA and mossad don't need hardware to snoop or damage critical infrastructure so the chinese don't either.

    Nice review of a nice machine.

    Good to read about how Goldmont finally played out. MS must've been pissed when Intel cancelled Broxton, but I imagine it's now Intel's turn with Windows on 835 coming. It's a shame Intel did what they did as Goldmont appears to be good silicon.

    The main competition in this price category is Chromebooks.

    The fact that you are pitting this device in your comparisons against a Yoga 3 Pro and a Asus UX305, and not a single Chromebook, says all that needs to be said about the sorry state of AT these days.

    Sure, I miss Anand & Brian, but when they left we got Jarred Walton Andrei Frumusanu, who at least knew what they were talking about. Ryan, these new writers you have hired do not stack up.
  • Ian Cutress - Saturday, March 11, 2017 - link

    To clarify an obvious error: Jarred was here 10 years, and both Andrei and Brett were here well before Anand left. Brett has been one of our freelance editors for over two years and attends events such as CES and Build as our Senior Laptop Editor. If you dislike the context of this review, sure, I'll grant you that opinion, but he has a large body of great work under him already. He's not new, he knows the score.

    On the testing front, it's a factor of what we get in for testing at any given time. Ultimately 90% of the time vendors want us to test their premium units, not something low cost. And there's a thousand low-cost options out there to potentially compare them against. When you've got a freelancer with time for 6-10 reviews a year, most of those will be high-end premium reviews. So if something interesting comes along, even at a super low price point, you compare against what you can or have at the time.

    Which in this case, the HP Stream 11 is the perfect comparison point for all these benchmarks. The Yoga/Surface are added to show the comparison to what a high-end notebook investment would be, which users always want to know without having to dig through our results database. We do have some Chromebooks in our database, but they are old. We haven't tested one in a long while (so we don't have one in for retesting), and they were all done by a different reviewer over 1000 miles away at the time. Most of the Chromebooks are Atom based anyway, which is why the HP Stream is still a relevant comparison. Heck, I even recommended the Stream 11 to someone I know a couple of weeks ago, and she loves it (especially now there's a 360-degree hinge version).
  • fanofanand - Monday, March 13, 2017 - link

    I get what the OP is saying but it is misguided in this case. Brett's reviews are solid. Some of the review product choices (case and PSU reviews) have been questionable but other than mobile reviews I haven't seen a real decline in the quality of Anandtech's journalism. Yes, they have had some major misses in the last year (especially in the GPU space) but what they have actually written has been fairly solid content.
