None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 1600. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G1 Tower as it has the ability to run 32 GB of RAM. The HP ProDesk 400 G1 Microtower can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the HP EliteDesk 800 G1 Tower has 10 USB ports. The HP ProDesk 400 G1 Microtower is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
Unfortunately, only the HP EliteDesk 800 G1 Tower has a DisplayPort. The HP ProDesk 400 G1 Microtower does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

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 HP EliteDesk 800 G1 Tower is better equipped as it comes with 5 SATA slot(s), while the HP ProDesk 400 G1 Microtower has 4 slot(s).

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!

Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The HP ProDesk 400 G1 Microtower comes with a decent 300 Watt PSU, but the HP EliteDesk 800 G1 Tower has a more powerful one rated at 320 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.
