Since many of our users are going to want to run different OSes on this, we wanted to give some of the key hardware specs. There is a lot on these machines that are customizable, but this at least gives you some sense of what hardware is available. If you want to know if your hardware is compatible with your OS, this list should help do that tie-out.

Intel Core i7-8700T (6 Cores/ 12 MB/ 12T/ up to 4.0 GHz/ 35 W)
For the 65W parts, this system would use the 130W power adapter. For the 35W CPU, these systems use a 90W power supply.

- Intel Q370 PCH
- 1x USB 3.1 Gen1 Front
- 1x USB 3.1 Gen2 Type-C Front

OSes From Factory
- Windows 10 Home (64-bit)
- Windows 10 Pro (64-bit)

- Windows 10 Home National Academic (64-bit)
- Ubuntu 16.04 SP1 LTS (64-bit)
- Neokylin v6.0 SP4 (China only)
The OS section can be a big deal. Sometimes the units are advertised as supporting Windows 10, but one gets a Windows 10 Home license. Also, some companies may order these units with FreeDOS in order to load their own OSes. If you are running Linux or another OS, then this is largely irrelevant. If you want to, or may want to, run Windows 10 Pro, knowing exactly which OS is on the device is ultra important.
Note: These systems sometimes change specs mid-generation. If you find another spec sheet with items you think we should add, please let us know in the comments.
Next, we are going to look at the performance and power consumption before getting to our final words.
Dell OptiPlex 7070 Micro Performance and Power Consumption
Instead of going through the entire Linux-Bench test suite, we are going to show a few performance and power numbers here to give a general sense of performance. We actually planned to do storage testing, but then we realized that there was a huge variability in terms of what drives could be found in machines.
Python Linux 4.4.2 Kernel Compile Benchmark
This is one of the most requested benchmarks for STH over the past few years. The task was simple, we have a standard configuration file, the Linux 4.4.2 kernel from kernel.org, and make the standard auto-generated configuration utilizing every thread in the system. We are expressing results in terms of compiles per hour to make the results easier to read:
There is a fairly huge gap here between this solution and the older generation Core i5-6500T. Older versions of these systems may seem like they only have two fewer cores, but that core count and often clock speed deficit means huge performance deltas. Also, if we compare this to the older AMD Pro chips we saw in the Project TinyMiniMicro HP EliteDesk 705 G3 Mini CE Review, the new Core i5-9500T is much faster.
7-zip Compression Performance
7-zip is a widely used compression/ decompression program that works cross-platform. We started using the program during our early days with Windows testing. It is now part of Linux-Bench.
We wanted to also show perspective regarding some of the embedded chips such as the Xeon D and Atom series. Here the performance is better than many of the lower-power chips that can be more costly.
OpenSSL is widely used to secure communications between servers. This is an important protocol in many server stacks. We first look at our sign tests:
Here are the verify results:
Comparing to some of the server chips, the Core i5-9500T is really starting to get to a reasonable performance range while maintaining lower power consumption. There was not a huge upgrade over the Core i5-8500T, however, we can see it start to get into the territory of a quad-core Intel Xeon E-2224G range.
Next, we are going to discuss power consumption before getting to our final words.
