Differences between Dell OptiPlex 980 DT and HP ProDesk 400 G2 Microtower

If you are looking for a more modern desktop, then you should go with the HP ProDesk 400 G2 Microtower which was released in 2014. The Dell OptiPlex 980 DT is older and entered production in 2010.

If you are looking for the smaller form factor the Dell OptiPlex 980 DT is the right one for you. It is smaller than the HP ProDesk 400 G2 Microtower 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 ProDesk 400 G2 Microtower as it is running a newer generation CPU. This is not to say that Dell OptiPlex 980 DT is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell OptiPlex 980 DT has 4 RAM slots while the HP ProDesk 400 G2 Microtower 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 HP ProDesk 400 G2 Microtower is using the faster 1600 MT/s RAM. The Dell OptiPlex 980 DT is slower by supporting RAM speeds of up to 1333 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 16 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 Dell OptiPlex 980 DT has 8 USB ports. The HP ProDesk 400 G2 Microtower is inferior in this regard and packs 6 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.

Unfortunately, only the Dell OptiPlex 980 DT has a DisplayPort. The HP ProDesk 400 G2 Microtower does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.

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 980 DT is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 400 G2 Microtower has 3 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell OptiPlex 980 DT, nor the HP ProDesk 400 G2 Microtower has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 980 DT comes with a decent 255 Watt PSU, but the HP ProDesk 400 G2 Microtower 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.
