Obsession with Handheld Computers
Preserving the handheld heritage of the computer revolution.
For the past couple of years I’ve been using 7-inch handhelds from One-Netbook as my main workstation.
The devices do their job pretty well. And from an aesthetic point of view, I find these devices quite pleasing. The only thing that bothered me was a bit boring lid with no marks what so ever. Therefore I decided to put my custom logo using a laser engraving technique. The lady in the engraving is Themis (quite unusual, without a sword and with open eyes).
"An ultra-mobile PC (ultra-mobile personal computer or UMPC) is a miniature version of a pen computer, a class of laptop whose specifications were launched by Microsoft and Intel in spring 2006." (c) Wikipedia. That was the dawn of the first UMPC epoch. This epoch did not last too long, because in the early 2010s major UMPC manufacturers ended its product lines. Few years later new manufacturers emerged and recreated UMPC market. The major one was the Chinese company GPD. GPD started the second UMPC epoch by releasing gaming handheld GPD Win in 2016 and the general purpose device GPD Pocket in 2017. Since then a whole bunch of UMPC devices were released. In this article we will compare performance of various UMPC devices from the second epoch: including the very first GPD Win and the most powerful UMPC up do the date – One-Netbook OneGx1 Pro.
Disclaimer. This article is not a comprehensive performance analysis of the 2-nd era UMPCs. All the test items are taken from my collection. Therefore the number of test items is quite limited. In case I add any new corresponding items to my collection, this benchmark survey might be extended as well.

The 11th generation Intel Core mobile processors (codename Tiger Lake) is a substantial breakthrough. It’s hard to believe that Core i7-1160G7 is faster than the high-end desktop processor Core i7-4790k, which was discontinued in 2017.
It is worth noting the variation in write speed across devices. Write speed of premium OneGx1 is significantly lower than the write speed of A1.
Few notes:
Since GPD Win performance of UMPCs has increased in many times in every single aspect.
Tiger Lake architecture is an outstanding breakthrough in both CPU and GPU performance.
