Differences between Dell XPS 8900 and HP EliteDesk 800 G8 Mini

If you are looking for a more modern desktop, then you should go with the HP EliteDesk 800 G8 Mini which was released in 2021. The Dell XPS 8900 is older and entered production in 2015.

If you are looking for the smaller form factor the HP EliteDesk 800 G8 Mini is the right one for you. It is smaller than the Dell XPS 8900 and will fit more easily under your desk.

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 XPS 8900 is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell XPS 8900 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 XPS 8900 is slower by supporting RAM speeds of up to 2133 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 XPS 8900 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. What is nice about the HP EliteDesk 800 G8 Mini, is that it has 3 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell XPS 8900 has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP EliteDesk 800 G8 Mini comes with 2 ports, while the Dell XPS 8900 has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G8 Mini is the better choice.

The Dell XPS 8900 comes with an HDMI port, while the HP EliteDesk 800 G8 Mini does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).

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 HP EliteDesk 800 G8 Mini has 0 slot(s).

If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the HP EliteDesk 800 G8 Mini. Sadly, the Dell XPS 8900 has no such slot, and you will be forced to use the SATA interface instead.

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 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.
