First look at an Intel Compute Card and Dock


Previously I covered the product details of the new Intel Compute Cards and Dock so this post looks at the physical devices and their actual operation and performance which is possible thanks to Intel who kindly provided me with a Compute Card (CD1M3128MK) and Dock (DK132EPJ).

The Dock comes with a small power brick with international plug adaptors similar in size to the power brick supplied with the Intel Core Compute Sticks and can be used with any of the Compute Cards. The Card slides into the Dock and requires a firm push to ensure connectivity and can't be retrieved unless the power is connected and the eject button is pressed.

Depending on the BIOS setting the Card will either boot immediately or after the power buttom is pressed.


The BIOS can be accessed by pressing F2 immediately:

Alternatively F10 can be pressed for the Boot Menu which is how to install an Operating System.


Both legacy and UEFI enabled OS are supported so a USB with an Ubuntu ISO will show two entries.

The specification of the CD1M3128MK Compute Card includes:


and the DK132EPJ Dock includes:


I first installed Windows 10 Enterprise Evaluation to look at performance under Windows.


The performance is very good in part because the SSD storage is attached via NVMe:






and the Core m3 Compute Card performance improves on the Core m3 Compute Stick:


The m3-7Y30 CPU makes watching 8K video possible:


Next I created a 20 GB partition so I could install and dual boot Ubuntu:


I used a standard Ubuntu 17.04 desktop ISO however whilst the installation completed sucessfully the Ubuntu NVRAM entry was incorrect and needed to be fixed by entering:

efibootmgr -b 4 -B
efibootmgr -c -d /dev/nvme0n1 -p 2 -l \\EFI\\ubuntu\\shimx64.efi -L ubuntu

This resulted in a F10 Boot Menu only showing Ubuntu:


which of course is not an issue as Windows can be booted from the GRUB menu:


as can Ubuntu:


Looking at the hardware in more detail for the Core m3 Card and Dock the CPU is a dual core m3-7Y30:

Running my usual suite of Phoronix tests shows a similar performance improvement of the Core m3 Card over the Core m3 Stick in Ubuntu:


with Ubuntu's Octane result being slightly better than in Windows:


No problems were encountered using Kodi to plays videos:


The Card itself is similar in size to a credit card and not really comparable to the earlier 'stick' form-factor:


The Dock is obviously bigger than a Stick:


and is also slightly larger than a NUC:


The Dock contains a fan as well as providing the additional ports. The fan is effective in keeping the temperature under control and with a resting temperature of around 30°C:


the temperature under load max'ed at just over 70°C:



However the fan does run all the time and is noticeably noisy when under load:



The external temperature of the Dock didn't exceed 30°C:


One issue I've encountered is when removing a Sandisk Ultra Fit USB from the front port. Because the USB is small it is very easy to accidentally press 'eject' or catch the 'power' button resulting in the Card shutting down.

The lack of a USB Type-C port on the Dock is also a noticeable omission given a DisplayPort is provided. Neither is there an SD or micro SD card slot.

Overall the Card and Dock combination works well and the Card is a great innovation for computing. Whether the Card will be popular as a retail product will be dependent on how useful it is seen together with its adoption by both manufacturers and the public alike.

The original 'stick' form factor initially succeeded as a consumer mini PC because early versions targeted both the portable computing goal and the concept of making TVs 'smart'. To a certain extent though the ongoing success of the 'stick' has been limited by its own form factor and 'boxes' have gained traction due to their provision of USB ports, inclusion of ethernet and better including fanless cooling. But whilst 'sticks' have remained popular for their portability and small size their commercial continuance is under threat. With market segments including digital signage seeing the potential their business requirements have heavily influenced the evolution of design.

A Card and Dock still fulfills the basic requirements of a mini PC. Portability is certainly addressed by the design with the ability to swap out Cards from a Dock. And if alternatives to the 'dock' such as a Card based laptop or a Card based all-in-one materialize then subject to cost popularity should follow. However whilst the Card may be well suited to the commercial market the Card and Dock face challenges in the consumer mini PC market given the size, fan, configurability and price as there are alternatives to using a Card and Dock as a mini PC.

Several Apollo Lake 'boxes' are already available in the market including fanless devices. For the Apollo Lake Cards if a fanless 'dock' creating a solution similar to the Zotac ZBOX PI225 was offered by Intel or their collaborating partners it would make the Apollo Lake Cards more attractive as an alternative 'next generation' Stick. 


Equally for the Core m3 Card the price and configurability offered by Intel's own NUC NUC7i3BNK or similar will probably undermine the need for a second generation Core m3 Stick and is likely preferable to a Core m3 Card and Dock combination although this will still be attractive to those who want a prebuilt solution.

However these points should not detract from what is a very good pair of product offerings. With Intel cancelling its next generation of 'stick' products the Card and Dock proposition must be seen as an alternative to fill that void. It is just that the market has changed and the future of Intel based 'stick' mini PCs is very much dependent on whether manufacturers can offer new products at price competitive points. Unless the Card becomes ubiquitous then 'boxes' are likely to remain as the de facto successor.
