Differences between Dell OptiPlex 3000 SFF and HP EliteDesk 800 G8 Tower

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3000 SFF which was released in 2022. The HP EliteDesk 800 G8 Tower is older and entered production in 2021.

If you are looking for the smaller form factor the Dell OptiPlex 3000 SFF is the right one for you. It is smaller than the HP EliteDesk 800 G8 Tower 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 Dell OptiPlex 3000 SFF as it is running a newer generation CPU. This is not to say that HP EliteDesk 800 G8 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP EliteDesk 800 G8 Tower has 4 RAM slots while the Dell OptiPlex 3000 SFF 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.

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 3200. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G8 Tower as it has the ability to run 128 GB of RAM. The Dell OptiPlex 3000 SFF can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the HP EliteDesk 800 G8 Tower has 11 USB ports. The Dell OptiPlex 3000 SFF 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. What is nice about the HP EliteDesk 800 G8 Tower, is that it has 4 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3000 SFF 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 Tower comes with 2 ports, while the Dell OptiPlex 3000 SFF has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G8 Tower is the better choice.

The Dell OptiPlex 3000 SFF comes with an HDMI port, while the HP EliteDesk 800 G8 Tower 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 HP EliteDesk 800 G8 Tower is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3000 SFF has 2 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 Tower has 1 M.2 slots while the Dell OptiPlex 3000 SFF 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 Dell OptiPlex 3000 SFF comes with a decent 300 Watt PSU, but the HP EliteDesk 800 G8 Tower has a more powerful one rated at 550 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.
