The information below has been extracted from an undated publicity leaflet from Dell/Wyse that is missing the usual dated copyright marking. A quick check with Google found mention of the D class mid-range Cloud Client family being launched in August 2012. The leaflet mentions:
"The range features dual core processors throughout with the D90D7 for Windows Embedded Standard 7, the D90DW for Windows Embedded Standard 2009, the D50D for Dell Wyse-enhanced SUSE Linux and the D00D for Dell Wyse WSM."
Another undated leaflet adds a D90Q7 to the line up - with a quad core processor.
The D-class is styled in a similar way to the Z class, but it is smaller than the Z class and also consumes less power - typically under 9 watts rather than under 15 watts.
The class may also be referred to as the 5000 series. I have a D10DP manufactured in October 2013 which carries the part number 909648-02L. According to a Wyse EOL document this part number is currently active (as of March 2017) and is for a 5010 with PCoIP (D10P) and comes with 8GB flash / 2GB RAM but a note says 'Flash Memory Upgrade Announcement 7/16/2015' which probably explains why mine only has 2GB of flash fitted. Another Wyse document implies that this was originally known as 5012-D10DP and is now known by the name Wyse 5010 thin client with PCoIP. Whatever it was known as there is no indication of 5010 or 5012 on the label - just the part number and Prod ID: D10P
When I first discovered the trailing P for PCoIP I wondered what might be coming as, up to now, all PCoIP thin clients I have seen have been based on a dedicated chip from Teradici. Luckily this not the case here as the D10P runs Wyse Thin OS with support for PCoIP.

The above are the specifications close to launch. It looks like things have changed a little since then in that the size of the flash drive has been increased.
