Differences between Dell OptiPlex 5040 SFF and HP EliteDesk 800 G4 Tower

If you are looking for a more modern desktop, then you should go with the HP EliteDesk 800 G4 Tower which was released in 2018. The Dell OptiPlex 5040 SFF is older and entered production in 2015.

If you are looking for the smaller form factor the Dell OptiPlex 5040 SFF is the right one for you. It is smaller than the HP EliteDesk 800 G4 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 HP EliteDesk 800 G4 Tower as it is running a newer generation CPU. This is not to say that Dell OptiPlex 5040 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (4 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.

The HP EliteDesk 800 G4 Tower is using the faster 2666 MT/s RAM. The Dell OptiPlex 5040 SFF 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 HP EliteDesk 800 G4 Tower as it has the ability to run 64 GB of RAM. The Dell OptiPlex 5040 SFF 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 G4 Tower has 11 USB ports. The Dell OptiPlex 5040 SFF is inferior in this regard and packs 10 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 Tower, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex 5040 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.

The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.

The Dell OptiPlex 5040 SFF comes with an HDMI port, while the HP EliteDesk 800 G4 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 G4 Tower is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 5040 SFF has 3 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 G4 Tower has 1 M.2 slots while the Dell OptiPlex 5040 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 5040 SFF comes with a decent 180 Watt PSU, but the HP EliteDesk 800 G4 Tower has a more powerful one rated at 500 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.
