Differences between Dell OptiPlex 3000 Tower and HP EliteDesk 800 G4 SFF

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3000 Tower which was released in 2022. The HP EliteDesk 800 G4 SFF is older and entered production in 2018.

If you are looking for the smaller form factor the HP EliteDesk 800 G4 SFF is the right one for you. It is smaller than the Dell OptiPlex 3000 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 Tower as it is running a newer generation CPU. This is not to say that HP EliteDesk 800 G4 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP EliteDesk 800 G4 SFF has 4 RAM slots while the Dell OptiPlex 3000 Tower 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 Dell OptiPlex 3000 Tower is using the faster 3200 MT/s RAM. The HP EliteDesk 800 G4 SFF is slower by supporting RAM speeds of up to 2666 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.

Ports

In total the HP EliteDesk 800 G4 SFF has 11 USB ports. The Dell OptiPlex 3000 Tower 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 G4 SFF, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 3000 Tower 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 G4 SFF comes with 2 ports, while the Dell OptiPlex 3000 Tower has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G4 SFF is the better choice.

The Dell OptiPlex 3000 Tower comes with an HDMI port, while the HP EliteDesk 800 G4 SFF 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 slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 3 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.

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 G4 SFF has 1 M.2 slots while the Dell OptiPlex 3000 Tower 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 G4 SFF comes with a decent 250 Watt PSU, but the Dell OptiPlex 3000 Tower has a more powerful one rated at 300 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.
