Devices Day at Microsoft grows every year. We have seen the numerous Surface announcements come through the special event held in NYC, as well as the peripheral devices around the ecosystem and a few smartphones as well. As this is the first Device Day after Windows 10 launch, we were greeted with numbers and facts about Windows 10 adoption rates, such as 110 million Win10 installs in 10 weeks, 1 billion questions asked through Cortana and 1.25 billion visits to the Microsoft app store. While the Surface Book announcement arguably stole the show, the big presentation everyone was expecting was for the new Surface Pro 4.

Panos Panay exalted the virtues and successes of the Surface Pro 3, such as the march towards 98% of users recommending the device. However the Surface Pro 4 aims to break such records. The device itself looks like an upgrade of the SP3, featuring 500 unique parts, however due to Intel’s major release of their 6th Generation Core platform, the SP4 was expected to get the whole platform upgrade. As a result we will see SP4 devices with Core M (Intel’s 4.5-watt platform), Core i5 and Core i7 processors up to 15W and ‘up to nine hours’ of battery life.

The Core i7 models will have Iris integrated graphics, which is part of Intel’s eDRAM strategy and we assume at this point that they will have 64MB of eDRAM. Microsoft showed the three-chip SoC in one of their presentation slides:

From 12-inches in the SP3 to 12.3-inches in the SP4, we are told that the device itself is not any bigger as Microsoft were able to reduce the size of the bezels. The display optical stack is also thinner than before, with Microsoft saying it is the thinnest optical stack ever fitted and comes with Microsoft custom silicon in the form of a G5 processor to help drive the display. The chassis is machined magnesium with the same SP3 kickstand that allows multi-position configurations. The SP4 comes in at 8.4 mm thick and a hybrid cooled system as well. The display retails the 3:2 aspect ratio of the SP3 but boasts a ‘5 million pixel display’, or 2736x1824 in numbers, with PixelSense. Each display is 100% sRGB with individual calibration, but also features 10-point multitouch.

The hardware will also come in 4GB, 8GB and 16GB models for DRAM, paired with 128GB, 256GB, 512GB or 1TB of PCIe 3.0 based SSD storage. We would assume this is PCIe 3.0 x4 in line with current high end storage in other PCs, although Microsoft does not specify at this point. 802.11ac 2T2R WiFi comes as standard with MIMO enabled.

Cameras come in the form of an 8MP rear facing auto-focus and a 5MP front-facing camera, both capable of 1080p. Nothing special was made about the microphones, but the SP4 comes with a full-size USB 3.0 port (note no USB 3.1 or Type-C here). Other inputs include a mini-DisplayPort for external displays, headphones/microphone jack and the Surface Connect for movement out to an external dock capable of driving more screens and USB ports.

The new Surface Pen is an upgraded model, featuring 1024 levels of pressure sensitivity and is presumably a derivative from Microsoft’s acquisition of pen technology from N-Trig. Microsoft will offer several colors of pen, and adjustable tips to account for the feel of the pen. On stage we noted that these will be labelled similar to pencils, and Microsoft will offer B, HB, H and 2H alternatives but prices were not announced for these. The pen is stored by magnetic attachments to the SP4, rather than a storage bay

New Type Covers are inbound as well, featuring a new switch design that facilitates quiet operation and 1.3 mm travel due to a new scissor design. The keyboard is backlit, and the trackpad is 40% larger than previous type covers. It is also worth noting that the trackpad uses precision glass, which Microsoft claims should give a more accurate representation when used. They weren’t 100% clear on the use of fingerprint sensors on trackpads, but there seems to be some versions with fingerprint sensors enabled as well. No pricing was given on the new Type Covers.

The basic SP4 box will come with the device, a Surface Pen and a power supply (24W with Core m3, 36W with i5/i7 that also has a USB charging port).  Prices will start from $900 and go up to $2200, with pre-orders starting on October 7th. Devices will be available from October 26th, but Microsoft failed to mention which regions they would be available, so given the price information we could assume it might be a US/NA initial launch at this point with other regions to follow. If we get more information on this, we will update this post.

At this point the exact CPU models are unknown, or whether each device will use some form of cTDP Up or cTDP Down to align with the chassis. One would assume the Core m3 is in cTDP Up mode to align with the performance of the others, though the battery life of the Core m3 device would be interesting nonetheless as the CPU draws less power overall. We will have to try and source at least one m3, i5 and i7 due to the configuration differences for review.

    And $400 for another 256GB of storage. Steve Jobs would be so proud!
  • jaydee - Tuesday, October 6, 2015 - link

    Definitely going the way of Apple here:

    i5 from 128GB - 256GB and 4GB to 8GB: $300
    i5 from 256GB - 512GB (no other changes): $400

    Either way it's a win for MS. Buy the low storage SP4 and have to rely on MS OneDrive cloud storage. Buy the high storage version and they get another $400 for $50 BOM increase.
  • IanHagen - Tuesday, October 6, 2015 - link

    God help us if we have to rely on OneDrive storage. That thing lost far too many documents while synchronizing for my taste. Not to mention when it mysteriously duplicates all my files forcing me to resort to black magic-ish shell scripts to sort the bloody mess out.

    I have held onto my Surface Pro 1 since it launched. I have been waiting for a reason to upgrade mainly because pen accuracy was always meh and the device lasts me 3 hours on a charge at best. So the Surface Pro 4 has peaked my interest. My debate is whether to choose the m3 or i5. I really just want to write and use Photoshop, probably not much gaming.

    Of course the grinding issue is the lack of storage or ram options. I would love the m3 with 256 gb of storage. Save $100 and go with the m3 or just suck it up and go for the i5?
  • fokka - Tuesday, October 6, 2015 - link

    best wait for reviews first. for only 100 bucks more i'm inclined to say go for the i5, but if it turns out the m3 has better battery life and sufficient performance, it might be the smarter buy in some cases.
  • mkozakewich - Tuesday, October 6, 2015 - link

    Did you get the 128GB model? It'll be more of the same. The CPU should be roughly similar, too, but it should last three times as long.

    You could also pick up the Power Cover. It gives me an extra two hours, at least.
  • defferoo - Tuesday, October 6, 2015 - link

    i'm confused by microsoft's power claims. they say it's 50% faster than a Macbook Air and 30% faster than a Surface Pro 3... so they're saying the Surface Pro 3 is faster than the Macbook Air? which models are they comparing? because the slowest MBA crushes the slowest SP3 and the fastest MBA kicks the pants off the fastest SP3. sounds like a lot of BS to me.
  • abrowne1993 - Tuesday, October 6, 2015 - link

    Obviously they're talking about the speed you can throw them.
  • IanHagen - Tuesday, October 6, 2015 - link

    They're probably claiming that the $1599 Surface Pro 4 is 50% faster than the $899 MacBook Air 11. Which is fantastic! I'd expect nothing different when considering the gigantic price gap lol
  • repoman27 - Tuesday, October 6, 2015 - link

    This was an insanely disingenuous claim. What they did is compare the base clock speed of the Core i7-4650U Surface Pro 3 (1.7 GHz) to that of the Core i7-6650U Surface Pro 4 (2.2 GHz) to arrive at "up to 30% faster". And then they compared the base clock speed of the Core i5-5250U MacBook Air (1.6 GHz) to that of the Core i5-6300U Surface Pro 4 (2.4 GHz) to get to "50% faster". Which anyone paying any attention will realize has no bearing whatsoever on real-world performance, because it's not like Intel made some 30-50% leap in performance between Haswell/Broadwell and Skylake.
