Face Off: Microsoft Surface Pro 4 vs. HP Spectre x2 12 vs. Fujitsu Stylistic Q665
We've already compared the Surface Pro 4 against itself as three separate SKUs. While the Surface series still offers the best Windows experience in a tablet form factor, we wanted to see how the latest Surface Pro 4 compares to a couple of other high ranking Windows tablets from competing manufacturers.
We encourage users to check out our dedicated review pages below for more data and detailed analyses of each of the three models. This comparison is by no means a replacement, but a condensed aid for those on the fence.
Case
Microsoft's tablet is the most robust with its sturdy magnesium casing that barely flexes. HP's tablet uses an aluminum build that feels just as sturdy, but the upper length of the back is made of weaker plastic that heavily contrasts the otherwise excellent build quality everywhere else on the device. The Fujitsu solution is largely plastic with above average resistance to twists and depressions. Its back cover, however, is more easily removable. In essence, we have a tablet with superb build quality but almost impossible maintenance (Surface Pro 4), a tablet that rivals Microsoft in quality with relatively easier maintenance (Spectre x2 12), and a tablet with a weaker build but with better repairability than the rest (Stylistic Q665).
In terms of weight, the Stylistic Q665 is the lightest at 753 g compared to 774 g and 850 g of the Surface Pro 4 and Spectre x2 12, respectively. When taking into account the keyboard docks, the Microsoft, HP, and Fujitsu tablets weigh 1066 g, 1229 g, and 1533 g, respectively. Thus, the Fujitsu can be heavier than the rest due to its thicker docking station.
Microsoft would win this round on design and quality alone, but it's hard to ignore how user-unfriendly the maintenance will be if the Surface Pro 4 ever experiences hardware issues. The HP offers the better balance with a mostly metal chassis and accessible screws on its back panel for troubleshooting.
Winner: HP Spectre x2 12
Ports in Comparison
Connectivity
There are vital differences in available ports between the three Windows tablets. For one, the HP lacks a full-size USB port in favor of two USB Type-C Gen. 1 ports for charging, transfers, docks, and video-out. While this will better future-proof the tablet, an innumerable number of users will certainly wish that it had at least one full-size USB port like on the Surface Pro 4 or Stylistic Q665. Be ready to carry a handful of USB Type-C adapters to make the most out of the Spectre x2 12.
Meanwhile, the Surface Pro 4 is the only one out of the three with no SIM or WWAN options. An objective winner in this category would be impossible to choose as each tablet includes an option not found on the others.

Input Devices
The keyboard dock for the Surface Pro 4 is a noticeable upgrade from the previous Type Cover for the Surface Pro 3. Travel is longer with a rigid case that does not yield significantly when typing. In comparison, the keys on the aluminum HP dock tend to clatter more loudly when typing. HP offers two different size docks as well - one with a Smart Card reader and one without.
The Fujitsu keyboard dock is the clunkiest since it utilizes mechanical locks instead of magnets like on the Surface Pro 4 and Spectre x2 12. Its surface will yield a bit more when typing and the keys include no backlight option.
As for the touchpads, both the Microsoft and HP tablets offer solid and reliable performance for scrolling and multi-touch inputs, especially on the wider touchpad of the HP. Nonetheless, the dedicated mouse keys of the Fujitsu are easier to use with clearer and more audible feedback than the integrated solution on the two competitors. It's a shame that none of the keyboard docks offer a TrackPoint to appease core business users.
Winner: Keyboard -- Microsoft Surface Pro 4
Touchpad -- Fujitsu Stylistic Q665
Display
Microsoft offers the larger display size, brighter backlight, higher pixel count, and more appropriate screen ratio for general work. While its gamut is as wide as the Fujitsu, colors are less accurate out-of-the-box unless if users opt in for the pricier Core i7 SKU. Thus, the display on the Surface Pro 4 m3 SKU should be more fitting for those who don't demand the most accurate of colors.
Grayscale is much worse on both the HP and Fujitsu compared to the Microsoft tablet. A calibration is recommended for warmer color temperatures on both of these devices. Additionally, while it's true that the Fujitsu tablet uses a matte panel to reduce glare and reflections, its backlight is also noticeably weaker than both Microsoft and HP, so its outdoor advantage is somewhat mitigated.

Performance
CPU Performance
Microsoft, HP, and Fujitsu all offer multiple CPU options beyond what we have here, so this comparison is only between the configurations on hand.
In terms raw CPU power, even the lowest-end Surface Pro 4 SKU can outperform the Spectre x2 12 and Stylistic Q665 according to CineBench benchmarks. Multi-core performance is over 30 percent faster than the older Broadwell Core M-5Y31 in the Fujitsu due to moderate throttling issues with the Stylistic Q665. Results are even slightly better on the Surface Pro 4 than on the HP for the same throttling reasons despite the higher-end Core m7-6Y75 in the Spectre x2 12.

GPU Performance
Microsoft's Surface Pro 4 comes out on top once again despite having the same integrated HD Graphics 515 GPU as the HP. The older HD Graphics 5300 in the Fujitsu lags behind by almost twofold.

Stress Test
We run both Prime95 and FurMark to simulate maximum stress and test system stability. These unrealistic conditions do not represent daily workloads, but are instead meant to put both the CPU and GPU at 100 percent capacity.
Our stress test results show why the Surface Pro 4 is able to outperform both the HP and Fujitsu in the aforementioned synthetic benchmarks. The Microsoft tablet is the only one out of the three where its stable CPU clock rate is higher than its base clock rate, so no major CPU throttling occurs. The lower core temperature ceiling on the Fujitsu means that both its CPU and GPU will throttle at much lower clock rates than the HP and Microsoft. The comparatively larger heat pipes in the Surface Pro 4 are likely responsible for the system's better performance under stress as well.

Temperature
The Fujitsu tablet is warmer under stress compared to the Microsoft and HP despite it having a lower temperature ceiling before throttling occurs. We were able to record a hot spot of just over 50 C at worst, which can be uncomfortable to hold. The HP runs a bit cooler than the Surface Pro 4 due in part to its thicker build.

Verdict
It's only fitting that the maker of Windows also produces the best Windows tablet. While the Surface Pro 4 isn't perfect, it carries a number of key advantages over the HP Spectre x2 12 that make it the overall easier recommendation. For one, even the lowest-end Surface Pro 4 SKU outperforms both the HP and Fujitsu in CPU and GPU benchmarks. It also has the longer battery life, the brighter display, and the more consistent build quality with no strips of plastic.
The HP tablet fills in the small gaps omitted by the Microsoft tablet, namely by offering SIM and Smart Card options, better repairability, and multiple USB Type-C ports. Thus, the Spectre x2 12 is an excellent alternative if all of these features are vital to the user. Unfortunately, the HP tablet falters in most other areas by having no USB Type-A ports, a dimmer display backlight, weaker colors, thicker and heavier build, increased sensitivity to throttling, and shorter runtimes.
Fujitsu's solution uses the increasingly unpopular latch-and-hook mechanism for its keyboard base instead of a rear stand as found on its two competitors. Its plastic build and slower performance will put off many users as well. It does, however, carry dual USB Type-A ports, a fingerprint reader, SIM slot, and matte display. It's a trade off between the Surface Pro 4 and Spectre x2 12, all things considered.
Microsoft Surface Pro 4 | HP Spectre x2 12 | Fujitsu Stylistic Q665 |
