Processor
Usually the newer the generation of the CPU, the better the performance and efficiency is. If your budget allows it, you should go with the HP EliteDesk 800 G8 Mini as it is running a newer generation CPU. This is not to say that Dell OptiPlex 7070 MT is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Dell OptiPlex 7070 MT has 4 RAM slots while the HP EliteDesk 800 G8 Mini has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.
The HP EliteDesk 800 G8 Mini is using the faster 3200 MT/s RAM. The Dell OptiPlex 7070 MT is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G8 Mini as it has the ability to run 128 GB of RAM. The Dell OptiPlex 7070 MT can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.
Ports
Both models have the same amount of USB ports for total count of 10. If this is not enough, using a USB hub is always a viable option. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the HP EliteDesk 800 G8 Mini as it has 3 USB3.1 ports (the Dell OptiPlex 7070 MT has 1).
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.
SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the Dell OptiPlex 7070 MT is better equipped as it comes with 4 SATA slot(s), while the HP EliteDesk 800 G8 Mini has 0 slot(s).
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the HP EliteDesk 800 G8 Mini has 1 M.2 slots while the Dell OptiPlex 7070 MT comes with just 1.
Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!
Power Supply
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The HP EliteDesk 800 G8 Mini comes with a decent 90 Watt PSU, but the Dell OptiPlex 7070 MT has a more powerful one rated at 360 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
