Differences between Dell OptiPlex 3040 SFF and HP EliteDesk 800 G1 SFF

If a more modern desktop is what you are looking for, then you should go with the Dell OptiPlex 3040 SFF which was released in 2015. The HP EliteDesk 800 G1 SFF is older and entered production in 2013.

If you are looking for the smaller form factor the Dell OptiPlex 3040 SFF is the right one for you. It is smaller than the HP EliteDesk 800 G1 SFF 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 3040 SFF as it is running a newer generation CPU. This is not to say that HP EliteDesk 800 G1 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The HP EliteDesk 800 G1 SFF has 4 RAM slots while the Dell OptiPlex 3040 SFF has only 2 slot(s). Of course this is not something to worry about. Just make sure you take it into consideration when planning how much RAM will your system be using.

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 1600. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G1 SFF as it has the ability to run 32 GB of RAM. The Dell OptiPlex 3040 SFF can do a bit less at max 16 GB. Most of the times, this should be sufficient for most users.

Ports

In total the HP EliteDesk 800 G1 SFF has 10 USB ports. The Dell OptiPlex 3040 SFF is inferior in this regard and packs 8 USB ports. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP EliteDesk 800 G1 SFF comes with 2 ports, while the Dell OptiPlex 3040 SFF has only 1.

The Dell OptiPlex 3040 SFF comes with an HDMI port, while the HP EliteDesk 800 G1 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 port 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 G1 SFF is better equipped as it comes with 3 SATA slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA. Unfortunately, neither the Dell OptiPlex 3040 SFF, nor the HP EliteDesk 800 G1 SFF has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

Remark: Make sure that the M.2 slot supports the PCIe (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 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/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 3040 SFF comes with a decent 180 Watt PSU, but the HP EliteDesk 800 G1 SFF has a more powerful one rated at 320 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.
