Dell Inspiron 3650 vs. HP ProDesk 400 G3 SFF

Differences between Dell Inspiron 3650 and HP ProDesk 400 G3 SFF

Both computers, the Dell Inspiron 3650 and the HP ProDesk 400 G3 SFF, were released during the same year - 2016.

If you are looking for the smaller form factor the HP ProDesk 400 G3 SFF is the right one for you. It is smaller than the Dell Inspiron 3650 and will fit more easily under your desk.

Processor

The two models have the same generation of Intel processors. We think that the 6 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.

The HP ProDesk 400 G3 SFF is using the faster 2133 MT/s RAM. The Dell Inspiron 3650 is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 400 G3 SFF as it has the ability to run 32 GB of RAM. The Dell Inspiron 3650 can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.

Ports

In total the HP ProDesk 400 G3 SFF has 8 USB ports. The Dell Inspiron 3650 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.

Unfortunately, only the HP ProDesk 400 G3 SFF has a DisplayPort. The Dell Inspiron 3650 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 3650 comes with an HDMI port, while the HP ProDesk 400 G3 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 3650 is better equipped as it comes with 4 SATA slot(s), while the HP ProDesk 400 G3 SFF has 2 slot(s).

M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the Dell Inspiron 3650, nor the HP ProDesk 400 G3 SFF has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.

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 G3 SFF comes with a decent 180 Watt PSU, but the Dell Inspiron 3650 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.
