Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

The Dell XPS 8900 is using the faster 2133 MT/s RAM. The Dell Inspiron 3650 is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell XPS 8900 as it has the ability to run 64 GB of RAM. The Dell Inspiron 3650 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 Dell XPS 8900 has 10 USB ports. The Dell Inspiron 3650 is inferior in this regard and packs 6 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 Dell XPS 8900 has a DisplayPort. The Dell Inspiron 3650 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
In case your monitor supports HDMI only, you will be happy to hear that both models come with an HDMI port.
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 XPS 8900 is better equipped as it comes with 5 SATA slot(s), while the Dell Inspiron 3650 has 4 slot(s).
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell XPS 8900, nor the Dell Inspiron 3650 has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.
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 Dell Inspiron 3650 comes with a decent 240 Watt PSU, but the Dell XPS 8900 has a more powerful one rated at 460 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.
