Differences between Dell OptiPlex 3050 SFF and Lenovo ThinkCentre Edge 72 Small

If a more modern desktop is what you are looking for, then you should go with the Dell OptiPlex 3050 SFF which was released in 2017. The Lenovo ThinkCentre Edge 72 Small is older and entered production in 2012.

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 Lenovo ThinkCentre Edge 72 Small 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 3050 SFF as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre Edge 72 Small is bad - it can still run some powerful CPUs, albeit being an older generation.

Memory

RAM slots is where your insert your RAM sticks. Each of those two models has 2 RAM slot(s) which should be taken into account when planning how much and what combination of RAM you are going to need.

The Dell OptiPlex 3050 SFF is using the faster 2400 MT/s RAM. The Lenovo ThinkCentre Edge 72 Small is slower by supporting RAM speeds of only up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex 3050 SFF as it has the ability to run 32 GB of RAM. The Lenovo ThinkCentre Edge 72 Small can do a bit less at max 16 GB. Most of the times, this should be sufficient for most users.

Ports

In total the Dell OptiPlex 3050 SFF has 8 USB ports. The Lenovo ThinkCentre Edge 72 Small is inferior in this regard and packs 6 USB ports. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals you will need to look at other models.

Unfortunately, only the Dell OptiPlex 3050 SFF has a DisplayPort. The Lenovo ThinkCentre Edge 72 Small does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of mode conversion.

The Dell OptiPlex 3050 SFF comes with an HDMI port, while the Lenovo ThinkCentre Edge 72 Small 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 port 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 Lenovo ThinkCentre Edge 72 Small is better equipped as it comes with 3 SATA 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 Dell OptiPlex 3050 SFF. Sadly, the Lenovo ThinkCentre Edge 72 Small has no such slot, and you will be forced to use the SATA interface instead.

Remark: Make sure that the M.2 slot supports the PCIe (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 6 Gb/s, while the PCIe 3.0 x4 will support speeds up to 32 Gb/s!

Power Supply

Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 180 Watts. Howver be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU option.
