Differences between Dell OptiPlex 3070 SFF and HP EliteDesk 800 G1 Mini

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3070 SFF which was released in 2019. The HP EliteDesk 800 G1 Mini is older and entered production in 2014.

If you are looking for the smaller form factor the HP EliteDesk 800 G1 Mini is the right one for you. It is smaller than the Dell OptiPlex 3070 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 3070 SFF as it is running a newer generation CPU. This is not to say that HP EliteDesk 800 G1 Mini is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

Both models have have equal amount of ram slots (2 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 Dell OptiPlex 3070 SFF is using the faster 2666 MT/s RAM. The HP EliteDesk 800 G1 Mini 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 Dell OptiPlex 3070 SFF as it has the ability to run 32 GB of RAM. The HP EliteDesk 800 G1 Mini 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 Dell OptiPlex 3070 SFF has 8 USB ports. The HP EliteDesk 800 G1 Mini is inferior in this regard and packs 4 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.

DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP EliteDesk 800 G1 Mini comes with 2 ports, while the Dell OptiPlex 3070 SFF has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G1 Mini is the better choice.

The Dell OptiPlex 3070 SFF comes with an HDMI port, while the HP EliteDesk 800 G1 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 OptiPlex 3070 SFF is better equipped as it comes with 2 SATA slot(s), while the HP EliteDesk 800 G1 Mini has 1 slot(s).

When your goal is to have the fastest SSD transfer speeds, an M.2 interface is crucial. Thus, it is good that both models have M.2 SSD slots. Today M.2 SSDs are not much more expensive than the average SATA drives, so it really does not make sense to invest in SATA drives anymore.

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 G1 Mini comes with a decent 65 Watt PSU, but the Dell OptiPlex 3070 SFF has a more powerful one rated at 200 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.
