Differences between Dell OptiPlex 980 SFF and HP ProDesk 600 G3 Microtower

If you are looking for a more modern desktop, then you should go with the HP ProDesk 600 G3 Microtower which was released in 2017. The Dell OptiPlex 980 SFF is older and entered production in 2010.

If you are looking for the smaller form factor the Dell OptiPlex 980 SFF is the right one for you. It is smaller than the HP ProDesk 600 G3 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 600 G3 Microtower as it is running a newer generation CPU. This is not to say that Dell OptiPlex 980 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 ProDesk 600 G3 Microtower is using the faster 2400 MT/s RAM. The Dell OptiPlex 980 SFF is slower by supporting RAM speeds of up to 1333 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 600 G3 Microtower as it has the ability to run 64 GB of RAM. The Dell OptiPlex 980 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 ProDesk 600 G3 Microtower has 11 USB ports. The Dell OptiPlex 980 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. 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 ProDesk 600 G3 Microtower comes with 2 ports, while the Dell OptiPlex 980 SFF has only 1. If you are planning to use multiple monitors, the HP ProDesk 600 G3 Microtower is the better choice.

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 HP ProDesk 600 G3 Microtower is better equipped as it comes with 5 SATA slot(s), while the Dell OptiPlex 980 SFF has 3 slot(s).

If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the HP ProDesk 600 G3 Microtower. Sadly, the Dell OptiPlex 980 SFF has no such slot, and you will be forced to use the SATA interface instead.

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 SFF comes with a decent 235 Watt PSU, but the HP ProDesk 600 G3 Microtower has a more powerful one rated at 250 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.
