Differences between Dell Inspiron 3670 and HP ProDesk 400 G5 SFF

If you are looking for a more modern desktop, then you should go with the Dell Inspiron 3670 which was released in 2019. The HP ProDesk 400 G5 SFF is older and entered production in 2018.

If you are looking for the smaller form factor the HP ProDesk 400 G5 SFF is the right one for you. It is smaller than the Dell Inspiron 3670 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 Inspiron 3670 as it is running a newer generation CPU. This is not to say that HP ProDesk 400 G5 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 (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.

The HP ProDesk 400 G5 SFF is using the faster 2666 MT/s RAM. The Dell Inspiron 3670 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 32 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 HP ProDesk 400 G5 SFF has 8 USB ports. The Dell Inspiron 3670 is inferior in this regard and packs 7 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.

Unfortunately, only the HP ProDesk 400 G5 SFF has a DisplayPort. The Dell Inspiron 3670 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

The Dell Inspiron 3670 comes with an HDMI port, while the HP ProDesk 400 G5 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 Dell Inspiron 3670 is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 400 G5 SFF has 3 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 HP ProDesk 400 G5 SFF comes with a decent 180 Watt PSU, but the Dell Inspiron 3670 has a more powerful one rated at 365 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.
