Differences between Dell OptiPlex 3050 SFF and Dell OptiPlex 7050 MT

Both computers, the Dell OptiPlex 3050 SFF and the Dell OptiPlex 7050 MT, were released during the same year - 2017.

If you are looking for the smaller form factor the Dell OptiPlex 3050 SFF is the right one for you. It is smaller than the Dell OptiPlex 7050 MT and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 7 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.

Memory

The Dell OptiPlex 7050 MT has 4 RAM slots while the Dell OptiPlex 3050 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.

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 2400. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 7050 MT as it has the ability to run 64 GB of RAM. The Dell OptiPlex 3050 SFF can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the Dell OptiPlex 7050 MT has 10 USB ports. The Dell OptiPlex 3050 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 7050 MT comes with 2 ports, while the Dell OptiPlex 3050 SFF has only 1. If you are planning to use multiple monitors, the Dell OptiPlex 7050 MT 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 7050 MT is better equipped as it comes with 4 SATA slot(s), while the Dell OptiPlex 3050 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 3050 SFF comes with a decent 180 Watt PSU, but the Dell OptiPlex 7050 MT has a more powerful one rated at 240 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.
