Differences between Dell OptiPlex 3000 SFF and Dell OptiPlex 5050 SFF

If you are looking for a more modern desktop, then you should go with the Dell OptiPlex 3000 SFF which was released in 2022. The Dell OptiPlex 5050 SFF is older and entered production in 2017.

Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.

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 3000 SFF as it is running a newer generation CPU. This is not to say that Dell OptiPlex 5050 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

The Dell OptiPlex 5050 SFF has 4 RAM slots while the Dell OptiPlex 3000 SFF 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 Dell OptiPlex 3000 SFF is using the faster 3200 MT/s RAM. The Dell OptiPlex 5050 SFF is slower by supporting RAM speeds of up to 2400 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 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 5050 SFF has 10 USB ports. The Dell OptiPlex 3000 SFF is inferior in this regard and packs 8 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 Dell OptiPlex 5050 SFF comes with 2 ports, while the Dell OptiPlex 3000 SFF has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 5050 SFF is the better choice.

In case your monitor supports HDMI only, you will be happy to hear that both models come with an HDMI port.

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 5050 SFF is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex 3000 SFF has 2 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 Dell OptiPlex 5050 SFF comes with a decent 180 Watt PSU, but the Dell OptiPlex 3000 SFF 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.
