Dell OptiPlex 3050M vs. HP ProDesk 400 G4 SFF

Differences between Dell OptiPlex 3050M and HP ProDesk 400 G4 SFF

Both computers, the Dell OptiPlex 3050M and the HP ProDesk 400 G4 SFF, were released during the same year - 2017.

If you are looking for the smaller form factor the Dell OptiPlex 3050M is the right one for you. It is smaller than the HP ProDesk 400 G4 SFF 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

Both models have have equal amount of ram slots (2 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.

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 HP ProDesk 400 G4 SFF as it has the ability to run 64 GB of RAM. The Dell OptiPlex 3050M 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 HP ProDesk 400 G4 SFF has 8 USB ports. The Dell OptiPlex 3050M 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.

The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.

The Dell OptiPlex 3050M comes with an HDMI port, while the HP ProDesk 400 G4 SFF 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 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 400 G4 SFF is better equipped as it comes with 2 SATA slot(s), while the Dell OptiPlex 3050M has 1 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 3050M. Sadly, the HP ProDesk 400 G4 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 3050M comes with a decent 65 Watt PSU, but the HP ProDesk 400 G4 SFF has a more powerful one rated at 180 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.
