Wireless

HP has gone all-Intel for its networking options, and with the current state of PC wireless, that’s not a bad decision. The Intel Dual Band Wireless-AC 8265 network adapter found in the HP Spectre Folio is one of the best of the latest generation, perhaps only surpassed by the newer 9260, but for 2x2 performance on a typical 40 Mhz wide Wi-Fi channel, the 8265 is no slouch.

WiFi Performance - TCP

On our wireless copy we achieved an average over 500 Mbps, which is in-line with what other manufacturers have gotten out of this NIC. The performance is doubly good when you add in the stability and reliability of the Intel wireless drivers, which surpass all other manufacturers in our testing.

For those that need data on the go, HP also offers LTE featuring the Intel XMM 7560 modem for a reasonable $158.99 upgrade if you’re doing a per-system configuration. Coupled with the amazing battery life and stylus support, the HP Spectre Folio would be an excellent machine for remote work.

Audio

HP offers Bang & Olufsen speakers on much of their lineup, and the Spectre Folio is no exception, with four speakers located in a strip above the keyboard.

The speakers get reasonably loud, peaking around 82 dB(A) measured one inch over the trackpad, but as is typically the case in thin and light designs, the speaker sound quality is poor with a very flat sound. Worse yet, when you flip the device into tablet mode the speakers get covered over by the display and leather casing, muffling the audio even further.

With most devices of this nature, the speakers are fine for video conferencing and the like, but proper headphones would offer much better audio. The 3.5 mm jack is nicely located at the bottom left corner of the display, but is part of the hinge and not the display so it stays put when moving the display into other use modes, so you’ll always know where to find it.

Thermals

Leather isn’t known to be a great conductor of heat, and with no active cooling solution, HP has to rely totally on the chassis to dissipate the heat generated by the Core i7-8500Y under load. Luckily the TDP is only 5 Watts, so handling this isn’t quite as big of an issue as it would be on a mobile workstation. The motherboard unit is located in the top of the keyboard deck, so it does have some aluminum around it that it can use as a heat sink.

To see how the Spectre Folio operates under sustained load, we utilized AIDA64’s CPU stress test feature to run the system at 100% load for about an hour. This provided plenty of time for the CPU to go through its separate power levels and settle into its TDP.

As with most passively cooled systems, the end result isn’t a smooth line but more of a see-saw pattern as the processor tries to achieve maximum performance, runs into a thermal limit, slows down, cools down, and then ramps up again.

Interestingly the Core i7-8500Y, despite only having a 5-Watt TDP, has a PL1 level of almost 18 Watts which it delivers for about 12 seconds before moving down to about 10 Watts for an additional 62 seconds, and then finally settling into the final result, which was the system bouncing between 7.53 Watts and 4.22 Watts, averaging 6.13 Watts of power draw. This resulted in an average frequency of 2045 MHz, and an average temperature of just 60°C on the processor. So despite the leather design, the HP can actually deliver slightly higher than the 5-Watt TDP on the processor, and the system itself never gets very warm except right above the CPU which wouldn’t impact usage at all.

Software

HP goes light on the software, which is appreciated. The main addition is their HP Support Assistant software which appears in the task bar by default, and provides access to driver updates, support, and troubleshooting. It’s well thought out, and while not everyone will appreciate this software, it’s nice to have a single pane of glass to access all of the support for a notebook.

The driver updates can be set to automatically install, or prompt for install.

If you do have an issue with the notebook there’s a virtual assistant to guide you through troubleshooting, or of course you can contact actual support if it is something more serious. HP isn’t alone offering this type of software, but their implementation works well.

HP also ships with a JumpStart icon on the Start Menu, which offers software and services to go alongside the notebook. It’s likely not needed by most people who are familiar with Windows 10 but for those that are not I can see some value. The layout is easy to use and it looks nice as well.

Finally, HP ships the laptop with a subscription to McAfee, so if you’d rather use a different AV you already own, or the built-in Windows tools, you’ll have to remove this.

Overall the software selection is almost exclusively useful utilities, so HP gets a star here.

    5W for 2 cores at 1.3GHz.

    Apple A12 is ~5W for 2 similarly fast (in terms of IPC) cores at ~2.5GHz + 4 slow efficient cores.
    10nm fiasco costed Intel a lot.

    Intel was never really as efficient for mobile (<5W) though, which is why their atom line failed spectacularly. ARM-based processors definitely has the advantage in the low-power field

    im sure HStewart will find a way to refute this.. and bash arm based cpus some how...

    I like the idea of a leather covered laptop, leather feels nice to the touch for me. And it makes a nice change I think. I have an HP ENVY X360 with the Ryzen 2500U in it, and it is a really great little machine and was £649 when I bought it. I can manually set the power limit to 30W and disable the skin temperature throttling for maximum sustained performance. It is around 3.1 GHz all core in multi-thread and 3.4-3.5 GHz in single threaded. In games the GPU can boost to 800-900 MHz and easily beats any Ultrathin Intel iGPU. Also I think at stock the 2500U is heavily throttling so it explains why it gets beaten a lot by this device in the review. (yes I am aware that the whole point is that they are efficient, and yes Intel's processor is more efficient, largely helped by the fact that Intel 14nm+++ has vastly superior power and voltage characteristics to GlobalFoundries 14nmLP/P).

    As for 5W, in this power envelope, 10/7nm will really, really help a lot here. I think if AMD can get 7nm low power mobile chips out soon-ish, they can have a really big competitive advantage against these 14nm Intel ones. But that said, Ryzen with onboard graphics is usually an entire cycle behind the desktop CPUs without. 12nm 3000-series APU are uninteresting for me, as it is basically 10% or close to that, more performance than my 2500U at the same power use. But I heard the idle power use is vastly improved. Sorry I typed a huge comment.

    Excellent review.

    This laptop was one of the inspirations for Project Athena, apparently.

    >Though the HP Spectre Folio wasn’t explicitly described as a Project Athena device, it’s representative of the collaboration between Intel and its PC partners.

    Props to the 1W display. I'd love a deep dive by Anandtech on how 1W (LPDT) panels work. IIRC, they use LTPS backplanes (a-si -> IGZO -> LTPS from worst to best), panel self-refresh, variable refresh rate, more efficient backlights, and some panel microcontroller efficiencies.

    So a lot of good technologies on their own brought together into a shipping product.

    In 2013, the Sony Fit 13A, 14A, 15A "Flip PCs" had screens that can flip down over the keyboard.

    Spun off, Vaio continued with the Vaio Z Flip in 2016.

    That model still seems to be sold in Japan.

    One benefit of the flip-down screen is that it is simpler and quicker to switch between keyboard mode and pen mode for taking notes. Other convertibles require picking up the whole computer, which can disturb your neighbors in a meeting or lecture. A benefit of the leather surfaces might be to quiet any clattering as the pieces fold together.

    I pre-order the Folio and have been using it as my daily work machine since. I agree with every point in this review.

    One thing to note is that Dell just added fans to its XPS 13 2-in-1 so it looks like the Folio could be the only premium fanless notebook with screen larger than 13" left in the market.
